Auxiliary training system, method and terminal for accurate collection and analysis of table tennis trajectory

Abstract

The invention belongs to the technical field of table tennis training, and discloses an auxiliary training system, method, and terminal for accurately collecting and analyzing table tennis trajectories. The training includes: a training room image acquisition module, an image denoising module, an image analysis module, and a ball point A real-time determination module, a central control module, a standard trajectory acquisition module, a display module, a trajectory comparison module, a deviation acquisition module, and a deviation early warning module. The invention collects the panorama image of the training room image and analyzes the collected image, and can realize the acquisition of the position information of the table tennis table, the position information of the trainer, and the actual movement route of the table tennis ball, and facilitates the teeing point and standard movement of the table tennis ball in the later stage Determination of the trajectory; by comparing the standard trajectory of the table tennis movement with the actual movement route of the table tennis ball, the trajectory comparison result can be obtained, and the determination of the trainer's dribbling deviation can be realized. Even if the early warning is corrected, the effect of training is better.

Description

technical field [0001] The invention belongs to the technical field of table tennis training, and in particular relates to an auxiliary training system, method and terminal for accurately collecting and analyzing table tennis trajectories. Background technique [0002] At present, table tennis is a popular ball game in the world, including attack, confrontation and defense. Match divides group, singles, doubles, mixed double etc. several; Before September 1, 2001 was divided into one innings with 21, now with 11 points for one innings; Adopt five innings three victory, seven innings four victory. Table tennis equipment specifications are as follows: the table is 76 cm high, 2.74 meters long, and 1.525 meters wide, and the color is dark green or blue; White or orange, matte, hard ball with a diameter of 40 mm and a weight of 2.7 grams, with a baffle height of 0.75 meters and a width of 1.4 or 2 meters, the same color as the table. [0003] In the existing table tennis train...

AI Technical Summary

Problems solved by technology

[0003] In the existing table tennis training, the coaches generally carry out hand-in-hand teaching, and then carry out repeated training for a long time according to the experience taught by the coaches. Table tennis is a sport, and different people have different experiences, so it mainly depends on the individual. In the process of training, existing table tennis players generally observe the trajectory of the table tennis ball with the naked eye. The observation results are not accurate enough, and it is difficult to summarize the relatively perfect hitting trajectory of the table tennis ball.

[0004] Through the above analysis, the existing problems and defects of the prior art are: in the process of training, the existing table tennis players generally observe the trajectory of the table tennis ball with the naked eye. hit track
