The Multiple Skills Of Sports Video And Image Processing Applied And Innovated In Track And Field Science

The Multiple Skills Of Sports Video And Image Processing based on the Non-Interfering Analysis and assessment, which are applied widely and developed in the modern sports science field。They play an important part in helping and supporting to improve the level of China sports science and the competitive abilities of China excellent athletes, they are approved and supported by the most of coaches and athletes in the sports training practiceThe main research methods were the documentation, the interview of experts and coaches and athletes, investigation, experimentation, logic and analysis, mathematical statistics. The subject was the males and females who took part in the final of triple-jump competation in Beijing Olympic Games. the elite male and female jumpers and triple-jumpers in China, the elite female shot-put players in China. The major research conclutions were as follows:1. The Sports Video And Image was defined about all the video and image data of the athletes' sport skill exhabition and sport tactics action and the sport instrument behaviors. The application of the Multiple Skills Of Sports Video and Image Processing in the track and field science field are visuality, rapidity, diversity and practicability, it is useful to promoting the Technique And Tactics ability of athletes evidently.2. The sports video and image of fast processing and replying system included the collection device of video and image and the transmit cable of video and image and the individul computer and the output device of video and image. And it also included the commom and special video and image processing software.its process included the many ways of video and image collection, and the video and image input in computer, and the compress ways of video and image, and the diversity of sports video and image processing techniques. 3. The non-interfence sport skills analysis are come ture by appling the Multiple Skills of sports video and image processing. It can satisfy to the many of visual need of sports technique analysis and evaluation through the key technique, such as the split screen and synchronous compare and superinposed synchronous compare and the trajectory tracking of video4. The sports video and image processing skill can get the key kinematics parameters fastly in the live place. the 2-D calibration scale, and the sports video and image's panorama, and the calibration technique acorrding to the defference players in the defference track, and the special video and image analysis software programed and so on. These sports video and image processing skills were innovation in the track and field scientisfic domain.5. Our elite women shotput players Compare to the world-class shotput players, their release velocity and release angle were more lower than the world-class players' significancely, and the release altitude was almost identical. It is the key to promote our sport achievement by improving our elite women shotput players' release velocity and release angle.6. The last two strides and the rhythm change of Our elite long-jump male were get by using the sports video and image processing skill. And these parameters are the same to the world-class elite long-jump male's. but the approach speed of our long-jumper male are less than the world-class elite long-jump male's, it is so as to the take-off vertical speed and the take-off angle significantly. The last two strides and the rhythm change of our elite long-jump female are the similar to the world-class elite long-jump female, but the approach speed and the take-off vertical speed and the take-off angle of our elite long-jump elite long-jump female are also less than the world-class elite female's significantly.7. The last two strides and the rhythm change of Our elite triple jump male were get by using the sports video and image multiple processing skill, these parameters are the equal to the world-class elite triple jump male's, and it is the same to the three times take-off angle. but the approach speed and the hop horizontal speed and the step horizontal speed and the jump horizontal speed of our elite triple jump male are less than the world-class elite triple jump male's significantly. the porportion of the second jump(step jump) is significantly less than the world-class elite trip jump male's in the porportion of three times jump in particular. The last two strides and the rhythm change of Our elite triple jump female are the equal to the world-class elite triple jump female's, and it is the same as to the three times take-off angle. but the approach speed and the hop horizontal speed and the step horizontal speed and the jump horizontal speed of our elite triple jump female are also less than the world-class elite triple jump female's significantly.the porportion of the second jump(step jump) of our elite triple jump female is significantly less than the world-class elite trip jump female's in the porportion of three times jump, so as to the third jump porporation, and the first jump porporation is singnificently larger than than the world-class triple jump female.
