Diving auto-tracking shooting and video feedback method and system thereof

Abstract

The invention relates to a diving automatic track shooting and video feedback method and a system thereof, comprising acquiring diving moment of a player accurately, according to the set of the player, acquiring delay time of the player reaching the highest point, predicting air position of the player for motion of the player after the highest point according to law of motion of free falling body, performing track shooting, finally broadcasting the act video shoot through a projector with delayed several seconds, so that the player can see the act effect of himself at once. The system comprises a sensor unit composed of a laser tube bundle, a photo-sensitive tube bundle and a signal processor; a master control unit comprising a master controller, a stepping motor and a camera; a display unit composed of a computer, a projector and a translucent screen. The invention is capable of representing air act of the diving player accurately, and enabling the player to see the act video of himself after completing diving, with input directly feed back to the player to enhance training effect.

Description

technical field [0001] The invention relates to a sports auxiliary training method and training auxiliary equipment, in particular to an auxiliary training method and training auxiliary equipment for tracking and photographing athletes' diving actions and playing back the video feedback of the actions immediately after the athletes come out of the water in professional competitive diving training. Background technique [0002] Feedback is a concept in control engineering. In the control system, a certain output can be obtained by inputting a certain control signal to a specific system, and different output effects can be obtained by inputting different control signals. [0003] Feedback is divided into positive feedback and negative feedback. The effect of feedback is to reduce the output deviation and get closer to the stable value, which is called negative feedback. [0004] With the continuous discovery of feedback phenomena in living organisms and the deepening of peopl...

AI Technical Summary

Problems solved by technology

[0010] 1. The start of the camera's whereabouts needs manual control;

[0011] 2. The cost and maintenance fee of the whole set of equipment is high, so it can only be used for TV broadcast of large-scale competitions, and cannot be used for daily training;

[0012] 3. The equipment is difficult to install. It can only be planned before the construction of the venues. This equipment is installed when the venues are built. Those venues that have not installed this equipment cannot be purchased separately;

[0013] 4. The shooting angle of the device is different from that observed by referees and coaches. There is no problem in using it for TV broadcasting, but it may cause certain parallax when used in daily training
