Research on Tennis Landing Point Measurement Based on Monocular Vision
In tennis competitions,professional equipment is currently mainly used to locate the landing point of tennis balls,which is costly and difficult to widely popularize in daily training.This paper proposes a monocular vision based ten-nis landing point positioning method.This method filters and calibrates the optimal combination of feature points based on the re projection error,obtains camera calibration parameters,and establishes a projection model to calculate the position information of the tennis landing point combined with the tennis movement trajectory.The experimental results show that the average error of the method in this paper is 9.42%and 25.76%lower than that of the method based on the projection model determined by Zhengyou Zhang calibration method and Tsai two-step method,respectively.
