Abstract

The invention belongs to the field of sports goods, and provides an eagle eye recognition method in a tennis match. The method includes the step 101 of periodically shooting pictures through a camera arranged at a field corner, the step 102 of positioning the pictures of tennis balls in the pictures and projecting the tennis balls on the X axis, the Y axis and the Z axis, the step 103 of calculating the distances between the shadows projected on the X axis, the Y axis and the Z axis and a calibration line, the step 104 of obtaining the three-axis coordinates of the tennis balls through the distances and the step 105 of repeatedly executing the steps till the coordinates of the tennis balls in all the pictures are obtained and drawing a tennis ball track according to the coordinates of the tennis balls, wherein the included angles between the camera and all edges are each 45 degrees. According to the technical scheme, the method has the advantage of being low in cost.

Description

technical field [0001] The invention belongs to the field of sporting goods, and in particular relates to a method and system for identifying eagle eyes in a tennis match. Background technique [0002] Tennis is a very common sport in the world. Most of the balls out of bounds in existing tennis games still rely on referees to judge. This method is very prone to misjudgment. In order to solve this problem, the existing technology provides an eagle-eye Judgment system, which can confirm the trajectory of tennis balls by synthesizing pictures captured by multiple high-speed cameras. Although this method is very accurate, due to the large number of cameras in the system, the cost is very high. Therefore, the existing eagle eye recognition The cost in the system is very high. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a method for identifying eagle eyes in a tennis match, which aims to solve the problem of high cos...
