In some embodiments, the apparatus for presenting a game video provided by the embodiments of the present invention may be implemented in software, and fig. 2 shows the apparatus 555 for presenting a game video stored in the memory 550, which may be software in the form of a computer program, a plug-in, or the like, for example, a video client, a short video client, or a live client. The display device 555 for game video comprises the following software modules: a ball game presentation module 5551, an acquisition module 5552 and a playback presentation module 5553, which are logical and thus can be arbitrarily combined or further split depending on the functionality implemented. The functions of the respective modules will be explained below.

The following description will take the terminal 400 in fig. 1 as an example to implement the method for displaying the game video according to the embodiment of the present invention. Referring to fig. 3, fig. 3 is a flowchart illustrating a method for displaying a game video according to an embodiment of the present invention, which will be described with reference to the steps shown in fig. 3.

It should be noted that the method shown in fig. 3 can be executed by various forms of computer programs executed by the terminal 400, and is not limited to the client 410, such as the operating system 551, the software modules and the scripts described above, and therefore the client should not be considered as limiting the embodiments of the present invention.

In step S101, in response to a video playing operation of a ball game, video data of the ball game is acquired, and a ball game process is presented according to the video data.

Here, the ball game video playing operation may be various forms of operations that are preset by the operating system and do not conflict with the registered operation; or may be various forms of operations that are user-defined and that do not conflict with registered operations. The video playing operation of the ball game comprises at least one of the following operations: click operations (e.g., single-finger click operations, multi-finger click operations, multiple continuous click operations, etc.); a sliding operation in a specific track or direction; performing voice operation; a motion sensing operation (e.g., an operation of moving up and down, a curved motion operation, or the like). Thus, the operation experience of the user can be improved.

Here, the video data of the ball game may be live video data in real time, or may be video data cached in a database.

In some embodiments, the client sends a data acquisition request to the server in response to a video playing operation of the ball game, so as to receive video data of the ball game sent by the server, and present a ball game process in a video playing page according to the video data.

In step S102, when a goal event occurs during the ball game, an actual pitching position and an actual goal position of the goal event are acquired.

In some embodiments, when a goal event occurs during the course of a ball game, the client receives the actual pitching position and the actual goal position of the corresponding goal event sent by the server.

When the ball game is a basketball game, the actual goal position corresponding to the goal event is the position of the basket; when the ball game is a football game, the actual goal position corresponding to the goal event is the specific position of the football entering the goal area; when the game is a football game, the actual goal location corresponding to the goal event is the specific location where the football enters the goal area.

For example, since the client obtains the position data in the two-dimensional coordinate system, the two-dimensional coordinate system is the coordinate established by looking down the viewing angle of the playing fieldThe origin of the coordinate system depends on the top view position of the player's foot when looking down the playing field, and thus, when the origin is the center position of the backboard, the actual pitching position may be (X) in fig. 9A₁，Y₁) (ii) a When the origin is the top corner of the field, the actual pitch position may be that in FIG. 9B (X)₂，Y₂) Or (X) in FIG. 9C₃，Y₃). As such, the actual shooting position described above may be the shooting position that can describe the sportsperson in a unique coordinate in the field, and the shooting position that can describe the ball (e.g., basketball, soccer, or football) in a unique coordinate in the field may be the actual shooting position described above, which is not limited by the present invention.

In step S103, a goal review animation is presented.

Here, the goal review animation includes: a playing field, and a goal curve from an actual pitch position to an actual goal position in the playing field. Wherein, since the goal review animation is used to simulate the goal event, the playing field in the goal review animation can be interpreted as a simulated playing field.

In some embodiments, a goal review animation is presented in the playback display page.

Here, the playback display page and the video play page may be displayed simultaneously, and specifically include: the playback display page and the video playing page are displayed in a split screen mode; the playback display page and the video play page are displayed on the same screen, for example, the playback display page and the video play page are arranged in the same display window, and the playback display page and the video play page are displayed in parallel in the same display window; the playback display page is displayed above the video playing page in a floating layer mode, so that the playback display page has transparency and cannot completely shield the video playing page. Of course, the playback display page and the video play page may also not be displayed at the same time, e.g., switching from the video play page to the presentation playback display page.

In some embodiments, the goal review animation is presented while at least one of the following information is presented: head portrait of the pitching person; name of the person who throws the ball; corresponding scores obtained by corresponding pitching; and (4) real-time scoring.

Taking the example of a basketball game as a ball game, since the rhythm of the basketball game is fast and the pitching speed of the players is fast, it is difficult for the users to clearly see the pitching position and the pitching angle when a goal event occurs. However, the goal review animation presented in the embodiment of the invention not only can accurately show the pitching position and the pitching angle to the user, but also can show the head portrait and/or the name of the current pitching person, the corresponding score obtained by the corresponding pitching person and the real-time score in real time to the user, so that the user can conveniently sense the progress of the current ball game in real time.

For example, in fig. 8, during the live process of watching the game video (i.e., the above-mentioned ball game video), the user may switch to the game status page card 801 (i.e., the above-mentioned playback display page) and present the real-time score 802 to the user.

The following describes a specific implementation of rendering a goal review animation.

In some embodiments, a goal review animation of at least one goal event is presented in response to a review trigger operation.

For example, a goal review animation of at least one recently occurring goal event may be presented; a goal review animation of a goal event occurring at any point in time may also be presented.

For example, the lookback trigger operation may be various forms of operations that the operating system has set in advance and that do not conflict with the registered operations. Types of lookback trigger operations include: clicking any position in the field screen (for example, single-finger clicking operation, multi-finger clicking operation, or multi-time continuous clicking operation); a slide for a particular track in the field scene (e.g., a slide from the basket position to an arbitrary position in the field, or a slide in an arbitrary direction along the field boundary line, etc.). Wherein, the scene picture is a picture presenting a goal review animation in the playback display page.

For example, in fig. 8, when the user clicks on any position of the simulated court 803, a goal review animation of at least one recently occurring goal event is presented. Therefore, the user can repeatedly watch the wonderful animation of the bowling through simple operation, so that the watching experience of the user is improved.

In other embodiments, for each goal event, a corresponding goal review animation is automatically presented in real-time.

For example, in fig. 8, when a goal event occurs, the simulated court 803 automatically presents a corresponding goal review animation in real-time. Therefore, the user can watch the wonderful animation of the bowling in real time, and the watching experience of the user is improved.

In still other embodiments, in response to a goal time list viewing operation, presenting a goal time list; in response to a goal time selection operation for the goal time list, a goal review animation of the goal event corresponding to the selected goal time is presented in the field.

Here, the types of the goal time list viewing operation include: a click on a goal time list button; clicking any position in the field screen (for example, single-finger clicking operation, multi-finger clicking operation, or multi-time continuous clicking operation); a slide for a particular track in the scene.

The goal time list may be displayed in a playback display page; or may be displayed in a goal time list page separate from the playback display page. The playback display page and the goal time list page may be displayed simultaneously, and specifically include: the playback display page and the goal time list page are displayed in a split screen mode; and displaying the goal time list page above the playback display page in a floating layer manner, so that the goal time list page has transparency and cannot completely shield the goal time list page. Of course, the playback display page and the goal time list page may also be displayed at different times, for example, when a time list viewing operation is received, switching from the playback display page to the presentation goal time list page; when a goal time selection operation is received, switching back to the presentation playback display page from the goal time list page.

In this way, the user can select the goal review animation corresponding to an arbitrary time point by a simple operation. And the user can acquire the accurate time of all the goal events by checking the goal time list, so that the watching experience of the user is improved.

In still other embodiments, a list of players is presented in response to a player list viewing operation; in response to a goal person selection operation for the goal person list, a goal review animation of at least one goal event corresponding to the selected goal person is presented in the field.

Here, the types of the goal list viewing operation include: clicking on a goal list button; clicking any position in the field screen (for example, single-finger clicking operation, multi-finger clicking operation, or multi-time continuous clicking operation); a slide for a particular track in the scene.

The goal list may be displayed in a playback display page; or may be displayed in a goal list page separate from the playback display page. The playback display page and the goal list page may be displayed simultaneously, and specifically include: the playback display page and the goal person list page are displayed in a split screen mode; and displaying the goal list page above the playback display page in a floating layer manner, so that the goal list page has transparency and cannot completely shield the goal list page. Of course, the playback display page and the goal list page may also be displayed at different times, for example, when a person list viewing operation is received, switching from the playback display page to the presentation goal list page; and when the goal person selection operation is received, switching back to the presentation playback display page from the goal person list page.

In this way, the user can select the goal review animation corresponding to any goal taker by a simple operation. And the user can obtain the players corresponding to all the goal events by looking up the goal event list, so that the watching experience of the user is improved.

In still other embodiments, in response to a goal list viewing operation, presenting a goal list; responding to the selection operation of the goal persons aiming at the goal person list, and presenting a goal time list corresponding to the selected goal persons; and presenting a goal review animation of the goal event corresponding to the selected goal time in response to a goal time selection operation for the goal time list.

Here, the type of goal list viewing operation is the same as described above; the type of the operation selected by the goal taker is the same as that described above; the type of the goal time selecting operation is the same as described above, and will not be described herein.

The goal person list page and the goal time list page may be displayed in the playback display page at the same time, specifically including: the goal person list page and the goal time list page are displayed in a split screen mode; the goal time list page is displayed above the goal person list page in a floating layer mode, so that the goal time list page has transparency and cannot completely shield the goal person list page. Of course, the goal person list page and the goal time list page may also be displayed differently, for example, when a goal time selection operation is received, switching from the goal person list page to the presentation goal time list page.

Therefore, the user can select the goal review animation corresponding to any goal person and any goal time through simple operation, and the watching experience of the user is improved.

In still other embodiments, a goal review animation of a goal event meeting the conditions of interest is presented.

Here, the condition of interest includes at least one of: a specific goal; a particular team of games; a specific pitching position; a specific goal location; a particular goal type; for a specific time.

Taking the example where the condition of interest is a particular goal person, the particular goal person may be any one or more of the participants in the game.

Taking the example where the condition of interest is a particular team, the particular team may be any one or more participating teams in the game.

Taking the condition of interest as a specific shooting position as an example, the specific shooting position may be any one or more positions or areas in the playing field, for example, a position of a bisector or a trisection in a basketball playing field, and a penalty area in a football playing field.

Taking the case that the condition of interest is a specific goal location, the specific goal location may be any one or more locations or regions in a goal area, for example, a basketball hoop in a basketball court is located, a goal area in a football court.

Taking the case that the attention condition is a specific goal type as an example, when the ball game is a football game, the specific goal type can be any ball, namely a goal event occurring after the game is restarted after a foul occurs in the football game; it may also be a goal, i.e. a goal event that occurs after a soccer ball is placed at a penalty point. When the game is a basketball game, the particular goal type may be a trivia, i.e., a goal event that is shot and hit outside the triple point of the basketball game.

Taking the example where the event of interest is a specific time, the goal event meeting the specific time may be a goal event within the last three minutes of the game.

The embodiment of the invention can individually present the goal review animation to the user, and avoid the waste of service resources caused by the presentation of too many goal animations while meeting the watching experience of the user.

Here, the attention condition may be set by the user uniformly for all ball games; or the system can be specially set for one or more ball games, and supports the user to set the attention condition and modify the attention condition before the game starts or in the game process; or may be specifically set for different types of ball games (e.g., basketball games or soccer games), and support the user to set and modify the attention conditions before or during the game. When the user does not set the attention condition, the client can use the default attention condition, wherein the default attention condition can be the attention condition set by other statistical users, the attention condition with the highest set frequency is taken as the default attention condition, and the user is supported to modify the default attention condition before the start of the competition or in the competition process; it is also possible to determine a default condition of interest based on historical behavior data of the user and enable the user to modify the default condition of interest before the start of the race or during the race.

As one example, historical behavior data of a user is obtained; determining review preferences according to historical behavior data; determining an attention condition according to the review preference; a goal review animation of the goal event satisfying the conditions of interest is presented.

Here, from the historical behavior data, a specific implementation of determining the review preference may be: calling a neural network model to perform the following processing on the historical behavior data: extracting a feature vector of historical behavior data; and mapping the extracted feature vectors to the probabilities corresponding to the review preferences of the plurality of candidates respectively, and determining the review preference of the candidate corresponding to the maximum probability as the review preference of the user.

The sample historical behavior data used for training the neural network model includes interaction behavior (such as comment, like or forward) data for a goal person, a game team, a pitching position, a goal position or a goal type. Therefore, the goal animation meeting the requirements of the user can be accurately determined through machine learning, so that the viewing experience of the user is met, and the waste of service resources caused by the excessive goal animation is avoided.

Here, from the historical behavior data, a specific implementation of determining the review preference may be: counting the interaction times and/or the interaction frequencies in the historical behavior data aiming at the candidate review preferences (including the goal persons, the competition teams, the pitching positions, the goal types and the time), and determining the candidate review preferences with the interaction times exceeding the interaction time threshold value and/or the candidate review preferences with the interaction frequencies exceeding the interaction frequency threshold value as the review preferences of the user.

The historical behavior data includes interaction behavior (such as comment, like or forward) data for a goal taker, a match team, a pitching position, a goal position, or a goal type.

As another example, when the historical behavior data of the user cannot be obtained or the amount of the historical behavior data of the user is small and is not enough to determine the review preference, the review preference of the user having a social relationship with the user is obtained; determining an attention condition according to the review preference; a goal review animation of the goal event satisfying the conditions of interest is presented.

Here, the user who has a social relationship with the user may be a member of an interest group of the same team, a member of a gummy ball of the same player, or the like. Therefore, the attention conditions corresponding to the users with similar hobbies in the ball game can be inherited, so that the users do not need to set the attention conditions by themselves, and the computing resources are saved.

In some embodiments, a goal review animation is presented based on a default viewing perspective.

Here, the default viewing angle may be a viewing angle at which the stadium is viewed with the spectator stand (or auditorium) as the review position.

For example, in the event status page card 801 of fig. 8, a goal review animation is presented based on the viewing angle of the spectator stand (or spectator seat) viewing the event field for the review position.

In other embodiments, a goal review animation is presented based on a viewing perspective looking from a review position toward a reference position of the playing field.

Here, the review position is an arbitrary position set inside the field, at the edge of the field, or outside the field by the review position setting operation. The review position setting operation and the review trigger operation described above may be the same operation for both setting the viewing position and triggering the goal review animation. Therefore, the operation steps of the user can be saved, and the operation experience of the user is improved.

Here, the review position being inside the field means that the projection position corresponding to the review position is within the boundary range of the field; the review position at the edge of the playing field means that the projection position corresponding to the review position is on the boundary line of the playing field; the review position being outside the field means that the projected position corresponding to the review position is outside the boundary of the field. The projection position corresponding to the review position is a position obtained by projecting the review position onto the playing field plane in a projection direction perpendicular to the playing field plane.

As an example, when the review position is at the edge of the field or outside the field, the reference position is the center position of the field; thus, the viewing angle is the angle between the line connecting the review position with the center position (i.e., the reference position) of the playing field and the plane of the playing field.

As another example, when the review position is inside the field, the reference position is a center position of a line connecting the actual goal position and the actual shot position; thus, the viewing angle is the angle connecting the review position with the center position (i.e., the reference position) of the connecting line between the two positions (the actual goal position and the actual goal position), and the angle between the connecting line and the playing field plane is the viewing angle.

In the embodiment of the invention, the user can select the review position at will, and the goal review animation under different viewing angles is presented according to the review position selected by the user, so that the user can feel the goal position and the goal angle of the goal time in an all-around manner, and the competition experience of the user is improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for displaying a game video according to an embodiment of the present invention, and based on fig. 3, step S104 may be further included before step S103.

In step S104, a goal review animation is generated based on the actual pitching position and the actual goal position.

In some embodiments, the client may invoke a corresponding service (e.g., an animation generation service) of the terminal, and the process of generating the goal review animation is completed by the terminal. The client may also call a corresponding service (e.g., an animation generation service) of the server, and the process of generating the goal review animation is completed through the server.

As an example, when the client calls the corresponding service (e.g., animation generation service) of the server to complete the process of generating the goal review animation, the alternative steps of step S104 are: the server generates a goal review animation according to the actual pitching position and the actual goal position; and sending the goal review animation to the client. Thus, step S102 can be omitted.

Next, a process of calling a corresponding service (for example, an animation generation service) of the terminal by the client and completing generation of a goal review animation by the terminal will be described as an example. It should be noted that the process of the client invoking the corresponding service (e.g., the animation generation service) of the server to complete the generation of the goal review animation is similar to that described below, and will not be described again.

In some embodiments, referring to fig. 5, fig. 5 is a flowchart illustrating a method for displaying a game video according to an embodiment of the present invention, and based on fig. 4, step S104 may include step S1041 and step S1042.

In step S1041, a spatial transformation process is performed on the actual planar coordinate system of the field based on the review position to obtain a simulated planar coordinate system including the field.

Here, the actual plane coordinate system is a coordinate system established by looking down the field from above the center position of the field; the actual pitching position and the actual goal position are coordinate points in an actual plane coordinate system.

In some embodiments, the review position is connected with a reference position of the playing field in a three-dimensional space of the playing field, and an included angle between the connection line and an actual plane coordinate system of the playing field is determined; rotating the actual plane coordinate system of the competition field by an angle corresponding to the included angle by taking the competition field boundary line which has an intersection with the extension line of the connecting line as a rotating shaft; wherein the direction of the extension line is a direction pointing from the review position to the reference position; and horizontally and vertically projecting the rotated actual plane coordinate system to a vertical plane which passes through the review position and is parallel to the rotating shaft to obtain a simulated plane coordinate system of the competition field.

Taking the review position in the audience table as an example, connecting the review position with the center position of the competition field in the three-dimensional space of the competition field, and determining an included angle between the connecting line and the actual plane coordinate system of the competition field; rotating the actual plane coordinate system of the competition field by an angle corresponding to the included angle by taking the competition field boundary line which has an intersection with the extension line of the connecting line as a rotating shaft; wherein, the direction of the extension line is the direction from the look-back position to the center position of the competition field; and horizontally and vertically projecting the rotated actual plane coordinate system to a vertical plane which passes through the review position and is parallel to the rotating shaft to obtain a simulated plane coordinate system of the competition field. By analogy, when the review position is inside the field or at the edge of the field, the manner of determining the simulation plane coordinate system of the field is similar to the above process, and will not be described herein again.

For example, in fig. 9C and 9D, since the review position is in the positive direction of the spectator stand, i.e. the Y-axis, if the perspective effect needs to be achieved, the actual plane coordinate system of the field (the coordinate system shown in fig. 9C) needs to be rotated by a certain angle (as shown in fig. 9D) towards the review position with the X-axis as the central axis, wherein the degree of rotation is the angle between the connection line of the review position and the central position of the field and the actual plane coordinate system of the field.

In step S1042, a goal curve is determined based on the transformed coordinates of the actual pitching position and the actual goal position in the simulation plane coordinate system.

In some embodiments, referring to fig. 6, fig. 6 is a flowchart illustrating a method for displaying a game video according to an embodiment of the present invention, and based on fig. 5, step S1042 may include steps S10421 to S10423.

In step S10421, a coordinate transformation matrix is determined.

Here, the coordinate transformation matrix is used to convert coordinate points in the actual planar coordinate system into corresponding coordinate points in the simulated planar coordinate system.

In some embodiments, the coordinates of the center position of the playing field are determined in an actual planar coordinate system; determining the coordinates of the center position of the competition field in a simulation plane coordinate system; according to the formula (X)_i，Y_i)×A＝(X_I，Y_I) Determining a coordinate transformation matrix; wherein (X)_i，Y_i) Is the coordinate of the center position of the field, (X)_I，Y_I) Is the coordinate of the center position of the field, and A is the coordinate transformation matrix.

In step S10422, a simulated pitch position corresponding to the actual pitch position and a simulated pitch position corresponding to the actual pitch position are determined in the simulated planar coordinate system based on the coordinate transformation matrix.

In some embodiments, the product of the coordinate transformation matrix and the coordinates of the actual pitch position is determined as the coordinates of the simulated pitch position; and determining the product of the coordinate transformation matrix and the coordinate of the actual goal position as the coordinate of the simulated goal position.

For example, when the coordinate of the actual ball-throwing position is (X)_a，Y_a) The coordinate of the simulated pitching position is (X)_a，Y_a) X is A; when the coordinate of the actual pitching position is (X)_b，Y_b) The coordinate of the simulated pitching position is (X)_b，Y_b) And (4) x A. Therefore, the coordinates of any pitching position or goal position corresponding to the simulation plane coordinate system can be obtained, so that a goal curve can be drawn conveniently in the follow-up process.

In step S10423, a parabola is generated as a goal curve based on the simulated pitch position and the simulated goal position.

In some embodiments, the simulated pitching position and the simulated goal position are connected, and a first coordinate point with a first preset distance from the simulated goal position is determined in the connection line; wherein the abscissa of the first coordinate point is the abscissa of the highest point in the goal curve; the vertical coordinate of the simulated goal position and the vertical coordinate of the simulated goal position are proportionally added to obtain the vertical coordinate of the highest point; and drawing a parabola to be used as a goal curve based on the simulated pitching position, the simulated goal position and the highest point.

As an example, the ordinate of the highest point is determined according to the formula z ═ x +60+30 y/H.

Here, z is the ordinate of the highest point, x is the ordinate of the simulated goal position, y is the ordinate of the simulated goal position, and H is the ordinate of the top of the field closest to the review position.

According to the embodiment of the invention, the goal event in the three-dimensional space is accurately simulated in a plane animation mode according to the video data of the ball game, so that the goal details such as the pitching position, the goal curve and the like can be displayed to the user in real time on the basis of reducing human resources and computing resources, and the user can conveniently sense the progress of the current ball game in real time.

Next, a description will be given by taking as an example a method for displaying a game video, which is provided by the embodiment of the present invention and implemented by the terminal 400 and the server 200 in fig. 1 in cooperation. Referring to fig. 7, fig. 7 is a flowchart illustrating a method for displaying a game video according to an embodiment of the present invention, which will be described with reference to the steps shown in fig. 7.

In step S701, the client acquires video data of the ball game sent by the server in response to the ball game video playing operation.

In step S702, the client presents the ball game process according to the video data.

In step S703, when a goal event occurs during the ball game, the client acquires the actual pitching position and the actual goal position of the goal event sent by the server.

In step S704, the client generates a goal review animation according to the actual pitching position and the actual goal position.

In step S705, the client presents a goal review animation.

It should be noted that the specific implementation manner in steps S701 to S705 is similar to the embodiment included in steps S101 to S104, and will not be described again here.

According to the embodiment of the invention, the client side accurately simulates the goal event in the three-dimensional space in a plane animation mode through data interaction between the server and the terminal, so that the goal details such as the pitching position, the goal curve and the like can be displayed to the user in real time on the basis of reducing human resources and computing resources, and the user can conveniently sense the progress of the current ball game in real time.

The method for displaying the game video provided by the embodiment of the invention is described below by taking the example that the ball game is a basketball game.

In the embodiment of the invention, the single two-dimensional coordinate data source obtained from the competition host is processed for the second time, is converted into the angle for watching the competition field from the viewing angle of the audience table for presentation after conversion, and the presented goal animation (namely the goal review animation) supports shooting at any shooting position after the corresponding angle is calculated.

Referring to fig. 8, fig. 8 is a schematic view of an application scenario of the method for displaying a game video according to the embodiment of the present invention. In fig. 8, during the live viewing of a game video (i.e., the above-described ball game video), the user may be switched to a game situation page card 801 (i.e., the above-described playback display page), and the user may be presented with a real-time score 802, as well as a simulated court 803 (i.e., the above-described simulated field). When a goal event occurs, the corresponding goal animation is presented on the simulated court at the same time, and the pitching position, the goal basket frame (namely the goal position) and the goal curve are marked in the goal animation. When the user clicks any position of the simulated court, the goal animation can be looked back.

Referring to fig. 9A to 9E, fig. 9A to 9E are schematic application scenarios of a game video display method provided by an embodiment of the present invention, and a specific implementation manner of the embodiment of the present invention will be described with reference to fig. 9A to 9E.

The client obtains the position data in a two-dimensional coordinate system, wherein the two-dimensional coordinate system is established by taking the center position of the backboard as an origin and looking down the game field, as shown in fig. 9A, the coordinate of the actual pitching position 901 obtained by the client is (X)₁，Y₁)。

The embodiment of the invention can convert the two-dimensional coordinate system into a pseudo three-dimensional coordinate system established by using the audience table as a viewing angle for viewing the competition field (namely the review position), and then presents the goal animation based on the pseudo three-dimensional coordinate system according to the actual pitching position and the actual goal position.

Specifically, the goal animation is realized by drawing a Bezier curve in the embodiment of the invention. The Bezier curve is drawn by means of three coordinate points which are respectively as follows: the coordinates of the basket (i.e., the goal position) and the coordinates of the pitching position and the coordinates of the highest point in the goal trajectory. As shown in FIG. 9A, assume that the current bowling position is (X)₁，Y₁) The process of drawing the goal curve specifically comprises the following steps:

in step S901, the field is translated to the lower left so that the top corner (X) of the upper right of the field is formed₅，Y₅) And moving to the position of the origin in the two-dimensional coordinate system.

As shown in fig. 9B, the coordinates (X) of the actual ball-throwing position₂，Y₂)＝(X₁，Y₁)-(X₅，Y₅)。

In step S902, the two-dimensional coordinate system is rotated counterclockwise by 90 degrees at the origin position.

As shown in fig. 9C, the coordinates (X) of the actual ball-throwing position₃，Y₃)＝(Y₂，-X₂)。

In step S903, the X-axis is used as a central axis to rotate clockwise by an angle θ (i.e., the included angle between the Y-axis and the Z-axis is 90 degrees — θ degrees), so as to present a perspective effect.

In step S904, the camera distance (i.e., the visual distance of the human eye) is adjusted to achieve the desired perspective effect.

As shown in fig. 9D, the camera is at the center of the field and the visual distance is a.

In step S905, the coordinates (X) of the actual shooting position are determined based on the camera distance₃，Y₃) Matrix-transforming to obtain transformed coordinates (X) of the actual ball-throwing position₄，Y₄)。

Here, the coordinates (X) of the actual ball throwing position₄，Y₄) I.e. the coordinates of the simulated pitch position as described above.

In step S906, the basket coordinates (X) are acquired₈，Y₈) According to the basket frame coordinate (X)₈，Y₈) And the coordinates of the pitching position (X)₄，Y₄) Determining the coordinates (X) of the highest point₁₀，Y₁₀)。

In some embodiments, since the goal curve is finally drawn in the plane coordinate system, a new coordinate system (coordinate axes of the new coordinate system are the X-axis and the Y-axis shown by the dotted line in fig. 9E) needs to be established, and based on the new coordinate system (i.e., the simulated plane coordinate system mentioned above), the basket coordinate is (X)₈，Y₈) The coordinates of the pitching position are (X)₄，Y₄) Thus, the coordinate (X) of the basket frame can be obtained₈，Y₈) And the coordinates of the pitching position (X)₄，Y₄) Determining the coordinates (X) of the highest point₁₀，Y₁₀)。

As an example, the highest point coordinate (X)₁₀，Y₁₀) The calculation mode of the horizontal and vertical coordinates is specifically as follows:

since the highest point of the shot is close to the rim, a distance R (which may be 40 pixels) is defined, and the horizontal distance from the highest point to the basket position is specified to be less than or equal to R, as shown in the circular range of fig. 9E. Thus, according to the basket coordinate (X)₈，Y₈) And the position coordinate (X) of the shot₄，Y₄) And a triangular formula enabling determination of the abscissa X of the highest point₁₀。

Visually, as the audience table is in the positive direction of the Y axis in the pseudo three-dimensional coordinate system, the closer the pitching position is to the audience table, the lower the height of the highest point of the corresponding goal curve is; the farther the pitching position is from the audience table, the higher the height of the highest point of the corresponding goal curve. Therefore, in the coordinates (X) of the rim position₈，Y₈) As a reference point, the ordinate Y of the maximum point is limited₁₀In the range [ b, c](b can take the value of 60 pixels, c can take the value of 90 pixels).

Thus, the ordinate Y of the highest point₁₀＝Y₈+b+Y₄/H(c-b)。

Where H is the pitch height in fig. 9E, and the value may be 120 pixels.

In step S907, according to the highest point coordinate (X)₁₀，Y₁₀) Basket frame coordinate (X)₈，Y₈) And the coordinates of the pitching position (X)₄，Y₄) And drawing a goal curve.

The embodiment of the invention can enrich the live content of the pictures and texts, help the user to comprehensively review the pitching position and the goal angle of the sportsman, and increase the interestingness, thereby prolonging the dwell time of the user page, increasing the stickiness of the user and improving the user experience.
