Description

Technical Field

[0001] The present invention belongs to the technical field related to tennis match penalty, and in particular relates to a tennis match penalty system and components thereof based on artificial intelligence technology. Background Art

[0002] In tennis matches, the traditional penalty method mainly relies on the naked eye judgment of manual referees, which has many limitations. On the one hand, when manual referees judge whether the tennis ball has crossed the line, they are easily affected by factors such as viewing angle and light, which makes it difficult to ensure the accuracy of the penalty. Especially when the tennis game is fast and the game is fierce, it is difficult for manual referees to make accurate judgments in an instant. On the other hand, the efficiency of the traditional penalty method is low. In some key games, the controversy over the penalty results often affects the progress of the game and the emotions of the athletes.

[0003] In addition, traditional tennis venues are relatively simple and lack effective technical means to assist in judging. For example, the boundary lines of the venue are usually just simple line markings, which cannot monitor in real time and accurately judge whether the tennis ball has crossed the boundary. At the same time, traditional camera equipment may have problems such as limited angles and insufficient clarity when shooting the trajectory of tennis balls, making it difficult to meet the needs of accurate judgment.

[0004] To sum up, the existing tennis match judging methods have problems such as low accuracy, low efficiency, and lack of technical support for venue facilities.

[0020] Compared with the prior art, the present invention provides a tennis match penalty system based on artificial intelligence technology and its components, which have the following beneficial effects:

[0021] 1. Accurate judgment: Combining the video capture and analysis system, radar capture and analysis system and lighting control system, artificial intelligence analysis is performed on whether the tennis ball has crossed the boundary, which improves the accuracy of the judgment. The movement trajectory and speed of the tennis ball are captured by multiple high-speed cameras, and combined with the analysis of the landing point of the tennis ball inside the sensing wireframe model and the capture of the tennis ball signal by radar, it is possible to judge whether the tennis ball has crossed the boundary in multiple dimensions, making the judgment more accurate.

[0022] 2. The induction wireframe is cleverly designed: the induction wireframe is composed of multiple boundary wireframes, and induction units are set inside each key wireframe, which can accurately detect whether the tennis ball has crossed the boundary. The induction light and induction radar on the induction unit cooperate with each other. When the radar captures the tennis signal, the lighting control system controls the induction light to light up, and combines video analysis to make a penalty, which is intuitive and efficient.

[0023] 3. Protection and cooling function: An air intake hole is set on one side of the induction lamp, and the air is sucked in by the suction fan to cool the induction lamp to extend the service life of the induction lamp. An air blowing hole is set on one side of the induction radar. The blown gas prevents debris from falling to the upper end of the induction radar and affecting signal collection, ensuring the normal operation of the radar. Filters are set at the air intake hole and the air blowing hole to prevent dust and debris from entering the induction unit and ensure the stability of the equipment.

[0024] 4. High-speed camera is flexible to adjust: The shooting elevation angle of the high-speed camera can be adjusted through the limit frame and can be fixed by a fixing knob to meet different shooting requirements. The shooting direction of the high-speed camera can be adjusted by rotating the limit sleeve on the limit plate, so that the movement trajectory of the tennis ball can be clearly and completely captured at all positions, and the speed of the tennis ball can be accurately analyzed. The limit plate and the limit sleeve are fixed in position by the limit card head and the limit card slot to ensure stable shooting. The arc design of the upper end of the limit card head enables the high-speed camera to be quickly adjusted and fixed. BRIEF DESCRIPTION OF THE DRAWINGS
