Embodiment Construction
[0051] The specific implementation manner will be described below in conjunction with the accompanying drawings.
[0052] see figure 1 , is a schematic diagram of the camera coordinate system of the computer-based ball motion processing method provided by the preferred embodiment of the present invention. like figure 1 As shown, the origin of the camera coordinate system is the center of the video camera, the positive direction of the X-axis is horizontally to the right, the positive direction of the Y-axis is vertically upward, and the positive direction of the Z-axis is horizontally backward. The camera coordinate system is used to describe various information of the racket and the user in the recognition module.
[0053] Please refer to figure 2 , is a schematic diagram of the virtual coordinate system of the computer-based ball motion processing method provided by the preferred embodiment of the present invention. like figure 2 As shown, the origin of the virtual coor...

The invention relates to a small ball sport processing method based on a computer. The method comprises the following steps that: position data of a racket are collected as well as speed data and force data of the racket and position data of a user are calculated; position data of a small ball before batting are calculated; according to the position data of the racket and the position data of the small ball before batting, it is determined whether the racket has hit the small ball; according to the speed data and / or the position data of the racket, a swing type of the racket is determined, and speed data of the small ball after the batting are calculated according to the force data of the racket; position data of the small ball after the bating are calculated; and it is determined whether the small ball falls into a region of a half table of the opponent. In addition, the invention also discloses a system for realizing the method. According to the method and system in the invention, a position and a swing motion of a user can be accurately reflected; it can be accurately determined whether a small ball is hit or not and a motion type of the swing motion can also be determined; therefore, the effect realized by the method and the system is very close to that of an actual body-building program.
Description
technical field [0001] The present invention relates to the field of computer applications, more specifically, to a computer-based ball motion processing method and system. Background technique [0002] The rapid development of computer technology is bringing more and more convenience to people, and the fitness project using computer for small ball exercise is one of them. At present, there are mainly two ways to implement small ball sports on the computer, such as table tennis, tennis, badminton and other sports or games: [0003] Operate with a computer mouse and keyboard. Among them, the keyboard is used to deal with what type of ball to play, and a button corresponds to a type of ball to be played; the mouse is used to deal with the strength, direction, and strength of the ball, and there will be a bar graph indicating the strength on the display. When the mouse button is pressed When you press down, the strength of this time is selected as the strength indicated by th...
