Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.
In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "e.g.," is intended to present concepts in a concrete fashion.
In addition, the system architecture described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application.
As shown in fig. 1, an architecture of a penalty method for badminton provided in the embodiment of the present application includes: three-dimensional laser radar, server, display terminal. The three-dimensional laser radar, the server and the display terminal are arranged on one side of the badminton court.
The badminton court is made by the international union. In the badminton court, the boundary line is divided into a bottom line and a side line. Wherein, the bottom line is a shorter boundary line of the badminton court specified by the International Union of feather. As shown in fig. 2, in the case of the singles match, the length of the base line is 5.18 meters; as shown in fig. 3, the length of the base line is 6.10 m in the double-beat match. And the sideline is a longer boundary line of the badminton court specified by the international union. The length of the sideline is 13.40 meters for both single play and double play games.
Three-dimensional laser radar is a radar system for detecting characteristic quantities such as position, speed and the like of a target by transmitting laser beams. The working principle is that a detection signal is transmitted to a target, then the received signal reflected from the target is compared with the transmitted signal, and after appropriate processing, relevant information of the target, such as target distance, direction, height, speed, posture, even shape and other parameters, can be obtained, so that the target is detected, tracked and identified. The laser changes the electric pulse into optical pulse and emits it, and the optical receiver restores the reflected optical pulse from the target into electric pulse and sends it to the display. In the embodiment of the application, the three-dimensional laser radar is used for calibrating the badminton. The three-dimensional laser radar calibrates the shuttlecock by presetting the volume value of the laser scanning object. The first threshold value has the same volume value as the volume value of a game shuttlecock specified by the international association.
A server, which is a type of computer, runs faster and is more highly loaded than a normal computer. A server provides computing or application services to other clients in a network. The server has high-speed CPU computing capability, long-time reliable operation, strong I/O external data throughput capability and better expansibility. Generally, a server has the capability of responding to a service request, supporting a service, and guaranteeing the service according to the service provided by the server. The server is used as an electronic device, and the internal structure of the server is very complex, but the difference with the internal structure of a common computer is not great, such as: cpu, hard disk, memory, system bus, etc.
And the display terminal is used for displaying the penalty result and the penalty time of the server. The display terminal can also comprise an alarm function and is used for giving an alarm sound when the server judges that the shuttlecocks are out of bounds and prompting the referees that the shuttlecocks are out of bounds.
The technical solution provided by the present application is specifically explained below with reference to the drawings of the specification.
As shown in fig. 4, a method for penalizing a shuttlecock provided in the embodiment of the present application includes the following steps:
s101, the server acquires position data of the shuttlecocks through the three-dimensional laser radar.
Optionally, the three-dimensional laser radar performs laser scanning on the badminton court, and acquires laser signal data reflected by objects in the badminton court. And then, the three-dimensional laser radar transmits the laser signal data reflected by the object to a server, and the server converts the laser signal data into three-dimensional coordinate data by data transformation.
Optionally, the server controls the three-dimensional laser radar to periodically perform laser scanning on the badminton court so as to acquire three-dimensional coordinate data of the badminton at the non-use time point. The scanning period of the three-dimensional laser radar may be set manually, which is not limited in this application.
It can be understood that, because the three-dimensional laser radar calibrates the shuttlecock, in the laser scanning process, the three-dimensional laser radar can only send the laser signal data of the reflection of the obtained shuttlecock to the server, and the server converts the laser signal data into the position data of the shuttlecock through data conversion, thereby avoiding obtaining the position data of other objects in the shuttlecock court and reducing the data calculation amount of the server.
S102, the server determines the height and the two-dimensional plane coordinate of the badminton according to the position data of the badminton.
Optionally, the server establishes the two-dimensional coordinate system in advance. The origin of the two-dimensional coordinate system can be the position where the server is located, and can also be other position points of the badminton court, or can be artificially set according to actual requirements, and the method is not limited in the application.
Optionally, the server determines the height and the two-dimensional plane coordinate of the badminton at the current time point in a coordinate change mode according to the three-dimensional coordinate data in the position data of the badminton. The two-dimensional plane coordinate is used for indicating the position of the badminton in the two-dimensional plane coordinate system. The two-dimensional plane coordinates include a first coordinate and a second coordinate, the first coordinate being a coordinate on a first coordinate axis, and the second coordinate being a coordinate on a second coordinate axis.
S103, the server judges whether the shuttlecocks fall to the ground or not.
As a possible implementation, the server determines whether the height of the shuttlecock is less than a threshold. When the height of the shuttlecock is smaller than or equal to the threshold value, the server determines that the shuttlecock falls to the ground. When the height of the badminton is larger than the threshold value, the server determines that the badminton does not fall to the ground.
Illustratively, the threshold is preset, and may be set to 0.1 mm, for example.
Optionally, the server judges whether the shuttlecocks fall to the ground or not according to the height of the shuttlecocks. If the judgment result is that the shuttlecock does not fall to the ground, returning to the step S101, and repeating the steps S101 to S103 for the shuttlecock at the next time point; if the judgment result is that the shuttlecock falls to the ground, the subsequent step S104 is executed.
For example, when the threshold is set to 0.1 mm, if the height of the badminton is 1 m, it is determined that the badminton does not fall to the ground, and then the step S101 is returned to, and the steps S101 to S103 are repeated for the badminton at the next time point; if the height of the badminton is 0 m, the badminton is judged to fall to the ground, and the subsequent step S104 is executed.
S104, the server judges whether the shuttlecock is out of range.
Optionally, if the value of the first coordinate of the badminton is not located in the first interval, or the value of the second coordinate of the badminton is not located in the second interval, determining that the badminton is out of bounds; and if the value of the first coordinate of the badminton is located in the first interval and the value of the second coordinate of the badminton is located in the second interval, determining that the badminton is not out of range.
Note that, since badminton games are divided into single-play games and double-play games, and the boundary settings of the two games are different, the settings of the first section and the second section are also divided into the following two cases:
(1) singleplay match
As shown in fig. 5, during a single play match, the server presets a first coordinate point, a second coordinate point, a third coordinate point, and a fourth coordinate point in a two-dimensional plane coordinate system. The first coordinate point, the second coordinate point, the third coordinate point and the fourth coordinate point are four end points of a rectangular court of the badminton single play match in a two-dimensional coordinate system. The first coordinate point and the second coordinate point are coordinates of two end points of one bottom line of two bottom lines of the boundary of the single play match in the two-dimensional coordinate system, and the third coordinate point and the fourth coordinate point are coordinates of two end points of the other bottom line of the two bottom lines of the boundary of the single play match in the two-dimensional coordinate system.
Optionally, the left end point of the first interval is a value of a first coordinate of the first coordinate point, and the right end point of the first interval is a value of a first coordinate of the second coordinate point; the left end point of the second interval is the value of the second coordinate of the third coordinate point, and the right end point of the second interval is the value of the second coordinate of the first coordinate point.
For example, when playing a single game, the origin of the two-dimensional coordinate system is set as the geometric center of the badminton court, namely the midpoint of the connecting line of the two net posts in the badminton court. At this time, the coordinates of the first coordinate point are (-2.59,6.70), the coordinates of the second coordinate point are (2.59,6.70), the coordinates of the third coordinate point are (-2.59, -6.70), the coordinates of the fourth coordinate point are (2.29, -6.70), the first interval is [ 2.59,2.59 ], and the second interval is [ 6.70,6.70 ].
(2) Double-hit match
As shown in fig. 6, during the double-play match, the server presets a fifth coordinate point, a sixth coordinate point, a seventh coordinate point and an eighth coordinate point in the two-dimensional plane coordinate system. The fifth coordinate point, the sixth coordinate point, the seventh coordinate point and the eighth coordinate point are four end points of a rectangular court of the badminton double-play competition in a two-dimensional coordinate system. The fifth coordinate point and the sixth coordinate point are coordinates of two end points of one bottom line of the two bottom lines of the boundary of the double-play match in the two-dimensional coordinate system, and the seventh coordinate point and the eighth coordinate point are coordinates of two end points of the other bottom line of the two bottom lines of the boundary of the double-play match in the two-dimensional coordinate system.
Optionally, a left end point of the first interval is a value of a first coordinate of the fifth coordinate point, and a right end point of the first interval is a value of a first coordinate of the sixth coordinate point; the left end point of the second interval is the value of the second coordinate of the seventh coordinate point, and the right end point of the second interval is the value of the second coordinate of the fifth coordinate point.
In the double-playing competition, the origin of the two-dimensional coordinate system is set as the geometric center of the badminton court, namely the middle point of the connecting line of the two net posts in the badminton court. At this time, the coordinates of the fifth coordinate point are (-3.05,6.70), the coordinates of the sixth coordinate point are (3.05,6.70), the coordinates of the seventh coordinate point are (-3.05, -6.70), the coordinates of the eighth coordinate point are (2.29, -6.70), the first interval is [ 3.05,3.05 ], and the second interval is [ 6.70,6.70 ].
Optionally, the server sends the time data of the current time point and the penalty result to the display terminal. The display terminal may be a mobile phone, a tablet computer, or a display screen, which is not limited in this application.
Optionally, after the server judges that the shuttlecock is out of bounds, alarm information is generated. The alarm information is used for enabling an alarm device in a badminton court to give an alarm and prompting a referee to the badminton out of bounds.
Through the technical scheme, the server can acquire the position data of the shuttlecock at each moment in the badminton process. Judging whether the shuttlecocks fall to the ground or not according to the height of the shuttlecocks in the position data, if the shuttlecocks fall to the ground, judging whether the falling points of the shuttlecocks are within the boundary or not according to the two-dimensional plane coordinates in the shuttlecock position data, and finally obtaining the penalty result of the shuttlecocks falling to the ground. Therefore, the badminton contact time and the contact position can be accurate, fair, objective and stable, adverse effects on badminton penalty caused by artificial factors are avoided, and the competition cost is saved.
