Video capture and processing method for teaching and training on baseball batting

Abstract

The invention provides a video capture and processing method for teaching and training on baseball batting by aiming at the current situation of lack of means for measurement key parameters of batting point position and the like during teaching and training on baseball batting. By means of acquisition of video images and adoption of video processing technology for automatic measurement of relevant parameters, accurate analysis data can be provided for baseball teaching and training, and accordingly baseball teaching and training efficiency can be better improved.

Description

technical field

[0001] The invention relates to the technical field of video collection and processing, in particular to a video collection and processing method for baseball teaching and training. Background technique

[0002] In baseball, the speed of movement of the bat, the direction of movement of the bat, the angle of the bat, the position of the point of contact between the ball and the bat on the bat, the position of the point of contact between the ball and the bat on the ball, and the position of the point of contact of the ball with the bat The speed of movement of the ball after hitting, the direction of movement of the ball, and the rotation of the ball will have a direct impact on the quality of the shot. In addition, the way of holding the bat and changes in body movements during hitting will also have an important impact on the quality of hitting. Taking the rotation of the ball as an example, when the baseball rotates, it will have an impact on the running ...

Embodiment Construction

[0022] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown in the figure, the video image is collected first, and the video image of the target personnel playing baseball is collected through the camera. In order to obtain clear and complete video images conveniently, in this embodiment, five high-definition and high-speed depth-of-field cameras are used for shooting. Two of the cameras are set at 3m above the 45° obliquely on both sides of the target person, and are used to photograph the target person's actions, the movement of the bat and the ball; The waist of the player is basically flat, and is used to shoot the movement of the bat and the ball; the remaining camera is set at 45° behind the player's side, at a distance of about 2m, and the height is basically the same as th...
