Detailed ways

The embodiments and examples of the present invention will be described in detail below with reference to the accompanying drawings.

The scope of applicability of the present invention will become apparent from the detailed description given below. It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given for purposes of illustration only.

Figure 1 shows a schematic side view of an embodiment of a sports device according to the present invention. The sports device includes a display 5, a protective screen 3, an infrared frame 2, a stand 6, a processor 7 (not shown in Fig. 1 ) and a memory 8 (not shown in Fig. 1). The display 5 is a liquid crystal or OLED display or other known suitable display and is fixedly mounted on the stand 6 . The protective screen 3 is, for example, a tempered glass screen, and is stacked on the display 5. There is a gap 4 between the protective screen 3 and the display 5 to avoid excessive impact on the display. The height of the gap can be determined according to the size and material of the display. For example 5-10mm. The infrared frame 2 is set or attached around the protective screen 3 to form four sides slightly higher than the plane of the protective screen so that the infrared transmitting and receiving sensors can be installed, and multiple pairs of infrared transmitting and receiving sensors (infrared transmitting tubes and infrared receiving tubes) 2-1 On the four sides, the control circuit board 2-2 that cooperates with the infrared emitting and receiving sensors can also be arranged in the infrared frame 2, as shown in FIG. 2 . The distance between adjacent infrared emitting/receiving sensors on the same side of the infrared frame may be, for example, less than 5 cm, and the smaller the distance, the higher the precision of the sports equipment of the present invention. The infrared emitting and receiving sensors on the four sides form a horizontal and vertical opposing grating grid during operation. Each pair of infrared emitting and receiving sensors sends a blocking signal to the processor 7 when its infrared rays are blocked by an object such as a basketball, as shown in the figure shown in 3. The memory 8 stores a computer program that can run on the processor 7, and the processor 7 can implement the virtual-real interaction process as shown in FIG. 4 when the processor 7 executes the computer program.

In S402, display a virtual target on the display 5, usually a character or a scene, such as a virtual basket or a virtual player (other images such as backgrounds, advertisement images, etc. can also be displayed at the same time), waiting for the user to face the preset of the virtual target The hitting area throws or passes the actual basketball (here, a basketball is used as an example, in other embodiments, it can also be other objects such as soccer balls, etc.). The preset hitting area is a part of the virtual target body, which is usually set to a regular shape such as a circle or a square (in this example, a circle is set). The position of the virtual object on the display may be a random position or a predetermined position. In either case, the center coordinates and the radius and/or the occupied area of the position on the display of the preset hitting area of the virtual target body are known. When the actual basketball touches the protective screen, since the basketball blocks some infrared rays emitted by the infrared emitting and receiving sensors, each corresponding pair of infrared emitting and receiving sensors will send a blocking signal to the processor.

In S404, after receiving the blocking signal, determine the X (horizontal) or Y (vertical) coordinate of the infrared emitting and receiving sensor corresponding to each blocking signal, the infrared emitting and receiving sensor that emits horizontal infrared rays corresponds to the Y coordinate, and emits longitudinal infrared rays The infrared transmitting and receiving sensor corresponds to the X coordinate. The dot of the coordinate system may be the lower left corner of the protective screen. Since the installation position of each infrared transmitting and receiving sensor is known, after determining which infrared transmitting and receiving sensor sends the blocking signal, the coordinates of the location of the infrared transmitting and receiving sensor can naturally be known.

At S406, the center and area of the blocking region are calculated according to all the determined coordinates. In an embodiment, all the X and Y coordinate values in the basketball impact process are accumulated to obtain the average value of the X and Y coordinates respectively, and the difference between the maximum and minimum X coordinate values and the difference between the maximum and minimum Y coordinate values are divided by 2 to obtain X. , the relative offset of the Y coordinate, the average value of the X and Y coordinates and the relative offset of the X and Y coordinates are added to obtain the coordinates of the impact center of the basketball (X ₀ , Y ₀ ). This accumulation algorithm can offset the influence of factors such as uneven surface of the basketball, rotation of the basketball, and the basketball sliding on the screen, and improve the accuracy of hit judgment. In an embodiment, the impact area of the basketball on the screen is a circle, the coordinates of the center of the circle are (X ₀ , Y ₀ ), and the radius R can be half of the difference between the maximum and minimum values of all X coordinate values and the largest among Y coordinate values. Half of the sum of the difference from the minimum value, that is, R=(X _MAX -X _MIN +Y _MAX -Y _MIN )/4, where X _MAX is the maximum value of the X coordinate, X _MIN is the minimum value of the X coordinate, and Y _MAX is the maximum value of the Y coordinate, and Y _MIN is the minimum value of the Y coordinate. The area of the blocking region can be calculated according to the radius R and the circle area formula.

At S408, it is determined whether the distance between the center of the blocking area and the center of the preset hitting area of the displayed virtual target is within a predetermined distance, and/or the distance between the blocking area and the displayed virtual target is Whether the overlapping area of the preset hitting area is greater than a predetermined percentage. If the distance between the centers is not within the predetermined distance, and/or the overlapping area is less than the predetermined percentage, it indicates that the basketball misses the virtual target, which is an invalid shot or pass, and the process ends; if the distance between the centers is equal to or less than the predetermined distance , and/or the overlapping area is greater than or equal to a predetermined percentage, it indicates that the ball is a valid shot or pass, and the process proceeds to step S410. The predetermined distance and the predetermined percentage can be preset according to the actual application. For example, the predetermined distance can be between 0 and the radius of the preset hitting area (circle) of the virtual target body, and the predetermined percentage can be between 50% and 100%. The higher the accuracy, the smaller the set distance value and the larger the set predetermined percentage. For example, the situation where the virtual character catches the ball: when a virtual character appears on the screen, the user will take the character as the target, and the user will pass the basketball in his hand to the target. If the basketball falls within the effective hitting range of the target (ie, the preset hitting area) , the pass is successful; the shooting situation of the virtual basket: a virtual basket can appear randomly in the game screen, and the user can shoot for the virtual basket. If the basketball falls within the effective hitting range of the virtual basket target, it is a shot. Success; hitting situations of various virtual targets: the game can design hitting targets in various scenarios, the user hits the target with a basketball, if the basketball falls within the effective hitting range of the target, the hit is successful .

In S410, counting or scoring is performed. Counting refers to accumulating valid shots, and scoring refers to scoring according to valid shots according to predetermined rules.

At S412, the counting or scoring result is displayed on the display such as the upper right corner.

In an embodiment, when the processor executes the computer program, it may further realize: receiving the scoring or counting result or video from another sports equipment in real time; synchronously displaying the scoring or counting result from another sports equipment on the display; or Video, so that the current user can understand another user's situation, online and other users PK.

Figure 5 shows a schematic diagram of another embodiment of a sports device according to the present invention. In addition to the components shown and described in conjunction with FIGS. 1 and 2 , the sports equipment of this embodiment also includes a backboard 1 and a basket 9 , the backboard 9 is mounted on the bracket 6 and located on one side of the display 5 such as above, and the basket 9 Installed on the backboard 1, the upper infrared reflection sensor 1-1 is installed in the backboard 1 and is located directly above the basket 9, such as 10 cm, and the lower infrared reflection sensor 1-2 is installed in the backboard 1 and is located directly under the basket 9, such as At 10 cm, the upper or lower infrared reflection sensor sends a reflection signal to the processor 7 when the basketball blocks the infrared rays emitted by the infrared reflection sensor and receives the reflected light from the basketball. The upper or lower infrared reflection sensor can be one or a group, and its installation position can be adjusted according to the type of infrared reflection sensor used, the size of the basket, the size of the basketball, etc. In other embodiments, the upper and/or lower infrared reflective sensors may also be absent. In this embodiment, when the processor 7 executes the computer program stored in the memory 8, the method for automatically determining a valid goal as shown in FIG. 6 can also be implemented.

In step S602, when the first reflection signal is received, it is determined whether the first reflection signal is sent by the upper infrared reflection sensor 1-1 or the lower infrared reflection sensor 1-2. If it is sent by the upper infrared reflection sensor 1-1, the process proceeds to step S604, and waits to receive the second (next) reflection signal; otherwise, returns to step S602.

In step S604, when the second (next) reflection signal is received, it is determined whether the second reflection signal is sent by the upper infrared reflection sensor 1-1 or the lower infrared reflection sensor 1-2. If it is sent by the lower infrared reflection sensor 1-2, the process proceeds to step S606; otherwise, it returns to step S604.

In step S606, it is determined whether the time difference between the first and second reflected signals exceeds a predetermined threshold. In the case where the upper and lower infrared reflection sensors are vertically arranged at 10 cm on each of the upper and lower sides of the basket, the path of the basketball free fall from the upper sensor to passing through the lower sensor is 20 cm, regardless of the initial downward velocity of the basketball, this is the basketball passing through The upper and lower sensors are the slowest and longest case. Using the gravity displacement equation h=1/2gt ² , h=20CM, g is the gravitational acceleration, it can be calculated that the maximum time t=0.2020s through the upper and lower sensors, taking into account factors such as software and hardware errors, the predetermined threshold (maximum duration) is optimal Choose 0.3 seconds. In this way, it can fight against other unexpected situations such as the basketball only touches the upper sensor and then bounces away or throws a double ball, and improves the accuracy of scoring judgment. If the predetermined threshold is not exceeded, the process proceeds to step S608; otherwise, the pitch is determined to be an invalid goal, the current process ends, and the process returns to step S602.

In step S608, it is determined that the shot is successful, and counting or scoring is performed.

In step S610, the counting or scoring result is displayed on the display such as the upper right corner.
