DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.

At present, the data display of live sports events or historical live broadcasts mainly focuses on the capture and transmission of real-time images, and cannot realize data analysis and data evaluation and display. It is precisely because of the lack of in-depth analysis and evaluation of data that the audience can only rely on intuitive images and limited statistical data to perceive the game when watching the game. This situation not only increases the threshold for viewers to watch, making it difficult for non-professional audiences to deeply understand the data and logic behind the game, but also increases the difficulty for professionals to review the game and conduct tactical analysis. In short, the existing data display methods have low data value, lack of in-depth interpretation and evaluation, have limitations, and cannot meet the objective needs in actual use.

In this way, the present disclosure provides a data display method that can determine, analyze and display the indicator data of the highlights and the objects associated with the highlights in real time, solving the problem of high threshold for viewers to watch and high difficulty in reviewing. Please refer to Figure 1, which is a flow chart of a data display method provided by an embodiment of the present disclosure. As shown in Figure 1, the method includes:

In step S101 , a video stream for a sports field is collected.

In the disclosed embodiments, the sports venue can be understood as the sports venue in the target scene. The target scene can be various live broadcasts of games and/or replays of historical games, such as live broadcasts or replays of at least one standard competition venue with multiple participants, such as football, basketball, table tennis, tennis, swimming, skating, track and field competitions, volleyball, etc.

Specifically, one or more cameras can be deployed in the sports field to collect video streams of the sports field from multiple angles. These cameras can be selected at appropriate locations in the sports field to capture comprehensive sports scenes, which can provide basic data for subsequent real-time tracking of moving objects and moving objects.

In step S102, the motion trajectory of each moving object is tracked in real time in the three-dimensional coordinate system of the sports field.

In the disclosed embodiment, the three-dimensional coordinate system of the sports venue can be established based on at least one of the fixed buildings or landmarks or fixed positions in the venue as the origin, and can be flexibly changed according to the actual situation when applied. For example, according to the type of event and the characteristics of the venue, a representative fixed landmark is selected as a reference point. These reference points can have obvious visual features, such as size, dimensions, specifications, etc., so that they can be accurately identified in the live broadcast screen. Use at least one lens angle such as the God's perspective (i.e., looking down from a high altitude) and the audience's perspective to obtain all-round information of the event venue. Based on the selected reference points and all-round information, a unified three-dimensional coordinate system is constructed. And each sports object can be all people who move in the sports venue, such as: at least one of the opponent athletes, teammate athletes, referees, etc. The moving object can be an object moving in the sports venue, which can be flexibly adjusted according to the type of sport. For example: at least one of various balls in a ball game, a sword in a fencing sport, etc.

In the present disclosure, at least one of a camera tracking system and a global positioning system (GPS) can be used to track the motion trajectory of each moving object in real time. Among them, the GPS can determine the position and trajectory of the moving object through satellite signals. The camera tracking system can use multiple high-definition cameras to capture moving images from different angles, analyze the image sequence through computer vision algorithms (such as at least one of optical flow method, background subtraction, target detection and tracking, etc.), and determine the motion trajectory of each moving object.

Specifically, in the present disclosure, the computer vision technology of the camera equipment can be used to identify the players, referees, balls and other targets in the field in real time. Based on the identified information and image processing technology, a three-dimensional coordinate system is established to calculate and determine the coordinate position of each target in the three-dimensional space. The position information of the target is captured by real-time and continuous tracking to form its motion trajectory. Of course, if there are multiple cameras, it is necessary to determine the synchronization of the trajectory data captured from different perspectives in time and space. This can be achieved by at least one method such as timestamp matching and coordinate conversion.

In step S103, when the motion trajectory of the target object meets the preset motion rules, the highlight clips in the video stream are captured.

In the disclosed embodiment, the target object may be a moving object that satisfies a preset motion rule. The preset motion rule may be related to a motion scene, and it can be understood that the motion rule is a computer simulation and representation of the motion rule in a real motion scene, which stipulates the rules of various aspects of the motion. The motion rule may include, but is not limited to, at least one of a scoring rule, a foul rule, a penalty kick rule, and the like. Taking the scoring rule as an example, for a football game, the scoring rule is the goal of the football, and the motion rule is whether the three-dimensional coordinate position of the football is strictly within the three-dimensional coordinate area of the door frame. For at least one of badminton and volleyball, the scoring rule is when the ball falls on the opponent's field and is within the boundary, or the opponent's player fails to legally return the ball, that is, it is considered a score. The motion rule is whether the position of the ball satisfies the range of the opponent's sports field. For a volleyball game, the scoring rule is that the volleyball crosses the net, and the motion rule is whether the position of the ball satisfies the effective area within the opponent's field. The highlight clip can be understood as a clip with at least one of the ornamental, tense, and decisive features in the game, and these clips are often closely related to the motion rule. The motion trajectory can be the actual moving path of the moving object in motion.

Specifically, it can be used to determine whether the motion trajectory of each moving object meets the preset motion rules. Once it is determined that the motion trajectory meets the preset motion rules, the process of capturing the highlights can be triggered. By capturing the highlights that meet the preset motion rules, it can be ensured that the audience sees the most entertaining part of the game. These clips often contain at least one of the key moments such as the high-level performance of the athletes, the exciting confrontation, and the direction of the game, which can attract the attention of the audience and enhance their viewing experience. The captured highlights can include a few seconds of video before and after the wonderful moment to ensure that the complete situation is captured, and the specific capture method is not limited here.

In step S104, the highlight clips and the index data are displayed, and the index data is used to evaluate the associated moving objects in the highlight clips.

In the disclosed embodiment, the index data may be evaluation data of the associated motion object involved in the highlight clip. The index data may be used to evaluate the capability of the associated motion object. Specifically, the index data of the associated motion object may be automatically determined and displayed while the highlight clip is captured and displayed.

It should be noted that the highlight clips and indicator data can be displayed by directly overlaying the indicator data in the highlight clips; or by displaying a data panel next to the highlight clips and displaying the indicator data on the data panel; or by displaying the indicator data instead of the associated motion objects in the highlight clips. The specific method of displaying the highlight clips and indicator data is not limited here.

In summary, the technical solution provided by the present disclosure can track the motion trajectory of a moving object in real time. Once the motion trajectory meets the sports rules (such as goal rules, etc.), the highlights in the video stream can be intercepted. And for the highlights, the indicator data of the associated moving object can be automatically determined and displayed, which can reduce the threshold for viewers to watch and the difficulty of reviewing, and enrich the audience's viewing experience. In this way, through precise positioning, real-time data analysis, evaluation and display, the problem of low data value and limitations can be solved, and the objective needs in actual use can be met.

As mentioned above, when displaying the highlights, the indicator data of the associated sports object can be displayed in combination, so that the performance of the associated sports object in the game can be evaluated more comprehensively, objectively and easily understood. In the disclosed embodiment, the indicator data includes but is not limited to at least one of the following: basic indicators and ability indicators.

The basic index is used to evaluate the basic motion conditions of the associated motion objects in the highlight clips, that is, the basic index mainly reflects the basic motion conditions of the motion objects in the clips.

Basic indicators include but are not limited to at least one of the following: technical level, position, direction, distance, and speed. Technical level can be understood as the technical proficiency of the sports object in the sports event, such as at least one of the frequency, stride, and reaction time of running; at least one of the dribbling, passing, and shooting techniques of basketball. Position is used to describe the position of the sports object on the sports field. Specifically, the origin of the three-dimensional coordinate system of the sports field can be used as a reference to determine the position of the sports object. Direction can reflect the moving direction of the sports object in the game. Specifically, the origin of the three-dimensional coordinate system of the sports field can be used as a reference to determine the moving direction of the sports object. Distance can be used to measure the distance between the sports object and at least one of the moving object and the target position. Specifically, the origin of the three-dimensional coordinate system of the sports field can be used as a reference to determine the distance between the sports object and at least one of the moving object and the target position. Speed reflects the moving speed of the sports object in the game. Specifically, the origin of the three-dimensional coordinate system of the sports field can be used as a reference to determine the moving speed of the sports object. At least one basic indicator such as technical level, position, direction, distance, and speed can be selectively displayed as needed, and the specific determination method is not limited here.

The ability index can be used to evaluate the individual ability of the associated sports object, that is, the ability index mainly reflects the sports performance of the sports object.

Ability indicators include but are not limited to at least one of the following: acceleration, strength, endurance, flexibility, agility, coordination, explosive power, technical execution, and tactical awareness. Acceleration can be used to evaluate the ability of the sports object to change speed during the game, that is, the change in the speed of the sports object between units. Strength can reflect the driving force of the sports object in the game. For example, determine at least one of the power of a short start and the power accumulation of a football kick. Endurance can measure the sports object's ability to continue to move in the game, which is particularly important in long-distance running competitions. Flexibility can reflect the sports object's physical flexibility and coordination in the game, which can be determined by the range of motion of the joints of various parts of the body of the sports object and the speed of conversion. Agility can be used to evaluate the reaction speed and movement speed of the sports object in the game. This can be determined by determining at least one of the sports object's ability to quickly change direction or posture. Coordination can reflect the sports object's physical coordination and movement fluency in the game. This can be determined by determining the sports object's ability to perform multiple actions at the same time. Explosive power can reflect the sports object's ability to generate maximum force in a short period of time. Technical execution can reflect the quality of the sports object's execution of specific sports skills, such as determining at least one of the swinging arm posture of running and the passing technique. Tactical awareness can reflect the ability of the sports object to understand and execute the game strategy. At least one ability indicator such as acceleration, strength, endurance, flexibility, agility, coordination, explosive power, technical execution, tactical awareness, etc. can be selectively displayed as needed, and the specific determination method is not limited here.

The index data can be obtained by using at least one of computer vision or image processing and analysis technology. The image processing and analysis technology can obtain the index data by using at least one of image segmentation method, transformation method, geometric morphology analysis method, etc.

Basic indicators can provide basic information about the associated objects, helping the audience to quickly understand the general situation of the game. It can lower the audience's understanding threshold so that they can easily obtain game information. For beginners and audiences who do not understand the game, basic indicators can help them integrate into the game more quickly and enjoy the fun of watching the game. The ability indicators can deeply evaluate the personal abilities of the associated objects, and can deeply understand the strengths and weaknesses of the associated objects, so that the audience can more comprehensively evaluate the performance of the associated objects in the game. In summary, the display of basic indicators and/or ability indicators can provide the audience with a comprehensive, in-depth, and easy-to-understand game analysis, which helps to lower the audience's understanding threshold of the game, and can also enhance their viewing experience and make them enjoy the charm of the game more.

The following will specifically describe how to intercept and determine the highlights of the embodiment of the present disclosure:

When the motion trajectory meets the motion rules, the data stream within the target time interval is intercepted in the video stream to obtain the wonderful clip;

The first endpoint of the target time interval is the moment when the motion trajectory satisfies the motion rule;

The second endpoint of the target time interval is the last contact moment, and the contact moment is the moment when the moving object contacts the moving object.

In the disclosed embodiment, the motion trajectory determined by tracking can be judged to determine whether it meets the preset motion rules. When the motion trajectory meets the motion rules, the two endpoints of the target interval can be determined, and the highlight clips are intercepted in the video stream according to the determined two endpoints. In the disclosed embodiment, one endpoint of the target interval is the moment when the motion trajectory meets the motion rules (such as: the moment when the ball enters the goal). The other endpoint of the target interval is the last contact moment when the moving object contacts the moving object (such as: the last moment when the ball and the athlete contact). Of course, the other endpoint of the target interval can also be the last two contact moments when the moving object contacts the moving object (such as: the last pass moment), and the determination of the specific target interval can be flexibly adjusted according to actual needs. Generally speaking, the highlight clip determined according to the data stream of the variable target interval can be a goal highlight clip that only includes a goal, or it can be a goal highlight clip and a pass highlight clip, and the specific intercepted highlight clip is not limited here.

In summary, by identifying the moment when the motion trajectory meets specific rules as the first endpoint of the highlight clip, the key or wonderful moments in the sport can be accurately captured. These moments are often the most interesting and valuable parts for the audience. Taking the contact moment as the second endpoint of the highlight clip, it can be determined that the intercepted clip contains a complete action sequence from beginning to end. This completeness helps the audience better understand and feel the athlete's skills. In this way, determining the intercepted wonderful moments can accurately capture the wonderful moments, maintain the integrity of the action, facilitate post-editing and processing, and adapt to a variety of application scenarios.

According to the above method, the wonderful clips can be intercepted and determined, and the indicator data can be displayed at the same time according to the intercepted and determined wonderful clips. The following specifically describes possible implementation methods for displaying the indicator data.

In the disclosed embodiments, the displayed indicator data may have different levels of detail, and displaying indicator data of different levels of detail can meet the needs and preferences of different users, and can also improve the practicality and efficiency of data analysis. In practical applications, the appropriate level of detail can be selected for display according to actual conditions and needs.

Exemplarily, the indicator data according to the embodiment of the present disclosure includes:

The first indicator data set includes: a three-dimensional coordinate system, and a motion trajectory, a basic indicator, and a capability indicator of a designated associated motion object; the designated associated motion object is an associated motion object that satisfies a motion rule;

and/or,

The second indicator data set includes: a three-dimensional coordinate system, and the motion trajectory of each associated motion object, basic indicators, capability indicators, and the calculated trajectory of the motion object.

In an embodiment of the present disclosure, the indicator data includes a first indicator data set and/or a second indicator data set. The second indicator data set is more detailed than the first indicator data set. The first indicator data set displays simple data in a three-dimensional coordinate system, including but not limited to: a three-dimensional coordinate system of a sports field, a motion trajectory of a designated associated sports object, basic indicators, and at least one of ability indicators. Among them, the designated associated sports object can be a sports object that meets the sports rules (such as: a player who scores a goal). The second indicator data set displays complex data in a three-dimensional coordinate system, including but not limited to: a three-dimensional coordinate system of a sports field, a motion trajectory of each associated sports object, basic indicators, ability indicators, and at least one of the calculated trajectories of the sports object. In layman's terms, the first indicator data set displays a three-dimensional coordinate system, as well as the indicator data and motion trajectory of the associated objects (such as: a player who scores a goal) that meet the preset rules. The second indicator data set displays a three-dimensional coordinate system, as well as the indicator data of all associated sports objects involved in the highlight clip (such as: at least one of a player who scores a goal, a player who passes a ball, an irrelevant player, a referee, etc.), the motion trajectory of all associated sports objects, and the calculated trajectory of the sports object. It should be noted that in addition to displaying the actual motion trajectory of each associated moving object, the second indicator data set can also display the calculated trajectory of the moving object. The calculated trajectory can be the motion path of a moving object predicted based on physical models and algorithms, which may differ from the actual trajectory, but it helps to analyze the motion laws and trends of the object. For example, in a football game, the flight path and landing point of the ball can be predicted by calculating the trajectory, thereby assisting coaches and athletes to make more accurate judgments and decisions. Of course, the calculated trajectory can also be a calculated trajectory obtained by deep learning method, and the specific method of obtaining the calculated trajectory is not limited here.

One possible implementation method is that the indicator data includes a first indicator data set; another possible implementation method is that the indicator data includes a second indicator data set; yet another possible implementation method is that the indicator data includes a first indicator data set and a second indicator data set. The specific indicator data is not limited here.

As described above, indicator data of different levels of detail can be displayed to meet the needs and preferences of different users. In the embodiment of the present disclosure, the display of indicator data is also closely related to the target scene. When there are at least two display screens in the target scene, indicator data of the same level of detail or different levels of detail can be displayed. The specific method of displaying indicator data on multiple screens is not limited here.

In an exemplary embodiment, if the target scene includes at least two display screens, the first indicator data set can be displayed on the main screen, and the second indicator data set can be displayed on the auxiliary screen. Of course, in specific applications, the level of detail of the indicator data displayed on the main screen and the auxiliary screen can be customized, and the specific display content is not limited here.

Of course, whether it is the main screen or the auxiliary screen, if a second indicator data set with a higher level of detail is displayed, it can be displayed in a variety of different ways. The following specifically describes possible implementation methods for displaying the second indicator data set.

One possible implementation method is: for multiple screens, partial contents of the second indicator data set can be displayed in chronological order.

In this exemplary embodiment, part of the content of the second indicator data set may be displayed on multiple screens in a time sequence. That is, the content of the second indicator data set may not be displayed in full, but may be displayed in a time sequence on multiple screens in sequence. The time sequence may include at least one of clockwise and counterclockwise. In this way, the user can see the details of different time periods of the game on multiple screens at the same time, which is convenient for analysis and understanding.

Another possible implementation manner is: displaying the second indicator data set in slow motion.

In this exemplary embodiment, when displaying the second data indicator set, slow motion display can be performed to achieve the effect of highlighting the display of the second indicator data set. Among them, the slow motion can be achieved by using at least one method such as segmentation rule slow motion and multiple speed slow motion. Among them, segmentation rule slow motion can set different playback speeds for each small segment to achieve the slow motion effect. For example, for key small segments, it can be set to normal speed or a slightly slower speed, while for other small segments, it can be set to a faster speed. Multiple speed slow motion can set the highlight segment as a key data point, and set different playback speeds based on this. The closer the data point is to the highlight segment, the slower the playback speed; the farther the data point is, the faster the playback speed.

In the disclosed embodiment, the method of displaying the indicator data also includes: displaying the indicator data by comparison. By displaying the indicator data by comparison, the association and difference between the indicator data can be identified more quickly, which helps the audience to understand the indicator data more intuitively and easily.

The method of comparing and displaying the indicator data can be to compare and display different indicator data for any associated motion object. In layman's terms, different indicator data of an object can be compared and displayed, that is, horizontal comparison of the indicator data.

For example, a possible implementation method of comparing and displaying indicator data is:

For any associated motion object of the highlight clip, obtain current index data and historical index data of the associated motion object;

Compare and display the current indicator data and historical indicator data.

The number and type of the compared indicator data are not limited here.

Specifically, it is possible to select and determine any associated sports object in the highlight clip. Determine the index data to be compared according to the event type. Obtain the current index data of the associated sports object. Retrieve and obtain the historical index data of the associated sports object from at least one of a database or a data storage module. Compare and display the current index data with the retrieved historical index data. This can be achieved in at least one form such as absolute value comparison, relative value comparison, etc.

For example, target athletes can be selected through representative highlights. According to the specific type of sport, appropriate comparison indicators can be selected, such as at least one of speed, strength, flexibility, and technical movements. It is necessary to analyze or record the current indicator data involved in the highlights, and obtain historical indicator data from the database. The indicator data of different highlights of the target athletes can be compared together to see in which aspects they have improved and in which aspects they need to improve. The analysis results can also be presented to find out the factors that affect the performance of the athletes and present them to the audience. Of course, the analysis results can be fed back to athletes and coaches to help them adjust their training plans and competition strategies. Regular horizontal comparative analysis can also be carried out to track the progress of athletes and adjust training and competition strategies in a timely manner.

The method of comparing and displaying the index data can also be to compare and display the index data of any two related sports objects. In layman's terms, the same index data of different objects can be compared and displayed, that is, the vertical comparison of the index data. Among them, the same index data can be understood as the index data of the same highlight segment.

Exemplarily, another possible implementation of comparing and displaying the indicator data is: for any two associated motion objects in the highlight clip, obtaining the indicator data of the associated motion objects;

Compare and display the indicator data of any two related sports objects.

The number and type of the compared indicator data are not limited here.

Specifically, any two associated sports objects in the highlight clip may be determined. The index data to be compared may be determined according to the event type. The index data of the two associated sports objects may be obtained. The index data of the two associated sports objects may be compared and displayed. This may be achieved by at least one form of absolute value comparison, relative value comparison, etc.

In summary, the indicator data can be compared and displayed in different ways. Comparative display of indicator data can help coaches, analysts and spectators better understand the technical characteristics and advantages of athletes.

In the disclosed embodiment, when displaying the indicator data, the indicator data can also be corrected by environmental factors, and the corrected indicator data can be displayed. In this way, the influence of environmental factors is fully considered, the accuracy and reliability of the indicator data can be improved, and more comprehensive and accurate indicator data can be provided to the audience, which is easy for the audience to understand.

Exemplary methods of displaying indicator data also include:

Acquire environmental influencing factors of the associated sports object; the environmental influencing factors include at least one of the following: natural environmental factors, social environmental factors, and personal factors;

Based on environmental factors, correct the index data of the associated moving objects;

Display the corrected indicator data.

In the disclosed embodiment, the environmental influencing factors include but are not limited to at least one of the following: natural environmental factors, social environmental factors, personal factors, etc. Natural environmental factors include but are not limited to at least one of the climate change and venue environment changes at that time. Social environmental factors include but are not limited to at least one of the audience atmosphere at that time and the changes in the venue buildings at that time. Personal factors include but are not limited to at least one of the age, psychological quality, injury and illness of the individual of the sports subject.

Specifically, the environmental influencing factors of the associated moving objects can be obtained. The weighted data of the associated moving objects can be generated according to the environmental influencing factors. The index data can be weighted analyzed according to the weighted data to obtain the corrected index data. Of course, this weighted data can also be presented only as reference data, not as the index data actually processed.

For example, when displaying athlete data, it is necessary to consider the positive or negative impact of at least one factor such as nature, social environment, and individual factors on the athlete data, and finally present the data after consideration and analysis. This consideration factor can only be used as a reference indicator without processing the actual indicator data. Among them, natural and social environmental factors can include the athlete's injuries. Personal factors can include indicators such as the athlete's age and psychological quality.

In summary, the indicator data can be corrected through environmental influencing factors, which can eliminate the deviation caused by environmental factors and make the displayed indicator data more objective and professional.
