The Digital Training System Study On Athletics Motion

The Digital Training System on athletics motion is very important in the development of sports. Studied on the Digital Training System by motion of golf, the system had been completed the video capture by tow cameras, also seen the actions both side, and compared with the specialists. The main function is: capturing motion video, parallel playing, drawing analysis, building train booklet, saving records and intelligent image processing.The new content of this system as follows: synthesized comparison, video sequence effect, velocity calculation and display, partial locked image and track description. Compared with various algorithms, we found out the most suitable algorithms to our system:(1) Video segmentation: using the algorithm of frame difference to segment foreground.(2) Video sequence effect: we adopted each two neighbor difference frame to add, and then mixed tow sets of pixel according to 50%, the final panoramas clearly show the full background and vivid action of athletes.(3) Velocity calculation and display: we calculated the average velocity of the special position through the golf rob length and time gap between two neighbor difference frame, finally, demonstrated with the form.(4) Partial locked image and track description: we found the algorithm of moving object detection. But because the complex background, the effects of tracking was not very well.At last, the Digital Training System has been developed by using C++ Builder.
