In order to improve fairness of tennis game

use computer vision technology

Lab VIEW platform

MATLAB software to realize computing

processing of data and construction of three-dimensional scene. Image of the tennis trajectory is processed by camera calibration algorithm of the Checkerboard pattern to obtain discrete center points

and obtains the smooth tennis trajectory curve by Gaussian fitting

and virtual three-dimensional scene of tennis is set up

and achieve playback of tennis track and judgment of split hit. Through the actual detection

the system has a high accuracy and low misjudgment

can help the referee to judge very well

it has a certain degree of practicality.
