Development of modern science and technology has promoted sports science and technology progress tremendously,high-tech has applied to motion training broadly, which improved training horizontal,moving engineering level and competition achievement. In train with the successive steps that development of sports science and motion,the improvement of the science training method and monitoring a means moves improved the effective training,importance improving motion achievement,already becoming one of sports developing direction. That science moves training is to build one kind of motion training pattern based on training intensity and control taking that enginery monitors the index and the technology monitoring an index as feedback information. At present,an training effectuation to monitor main application's from the technology monitors is the move analytical system of picture recording.But,moving analytical system of picture recording is returning the grave defect back to existence,being that the unable timely feedback information and operation are complicated mainly. Be one or two monthly after the image being shot about three moons ability gets the testing data even,can not realize real time supervisory control,the gains data not having reality guiding value. But affect a kinematics studying the bottleneck that the fleetness couples back depends on the data acquisition handles method,the tradition analysis method is that point,amount of work are enormous from manpower be sentenced the human body Joints,the operation affecting the speed coupling back,distinguishing not only that,artificial orientation is monotonous, weary error often from this and handle error,moreover repetitiveness difference. Move picture recording analysis systematically handling certain difficult,to complicated,need to have and training ability operation strictly. As for busy coach,it is not easy to control. Make use of a computer to carry out the automation orientation on the human body Joints,have money spent is low,the period is short,accuracy is high,the repetitiveness is easy to wait for merit,feedback,maneuverability are can realize real time supervisory control and the fleetness mainly most easy to have very much developing future.For the bad maneuverability problem resolving analytical motion picture recording system information feedback slowly and may,the thesis chooses dash as the object of study,this is because:The dash project not only self technology action analysis is very important,but also it is moves the project basis other. A high jump,a long jump,being still basketball,football , badminton and so on is various , being to be completed in running move[1].Therefore,originally with platform providing a theory research method and software for moving a project other while the Joints resolving the dash human body counts the automation orientation. If the peculiar law leading-in will move a project one by one is such platform,the Joints being OK to realize these projects counts the automation orientation.The thesis takes dash as object of study,takes computer as implement,first, uses the method which divides first fills again, obtains image which the double image, does not vibrate. And then according to form line rock bottom coordinate (x,y axis coordinate) change characteristic,from the computer,the automation looks at and appraises time the motion distinguishing peculiar moment (be away from the field moment and land to wait),and then distinguishing diversity. And,according to dash,this looks at and appraises time the project characteristics of motion and the motion already ascertaining that,looks at and appraises face to face no at the same time even the different Joints being unlike moment adopts corresponding method.The area that every Joints counts in the human body outline characteristic point that area gains easy to track aspect (human body outline maximal point,the point of bottom etc.) is used to ascertain the human body combining with dash characteristics of motion is tracked,specifically for the peculiarity that every Joints puts and the peculiarity looking at and appraising time every,area centre and radius,and self fit in with being in progress according to action continuity adjust the tracking adopting diversity on every joints not looking at and appraising at the same time. Distance is equal according to the centre of a circle to every circumference point this one principle , finds with upper Joints vicinity form line characteristic point from when equal point (be a midpoint in general) is what be asked an Joints to burn.Study the continuity according to motion originally,judge the motion image special case appearing on the point distinguishing the human body Joints. And,the oblique tones Joints making use of long law of link,the slope from the coordinate that the Joints adjacent to counts to link to calculate visible entering the human body outline burns; The Joints making use of pixel difference,the outline picking up the visible oblique tones arm to resolve the visible oblique tones arm enters trunk outline problem; With the period It can be seen that oblique tones Joints point coordinates moves half,the acquisition secretly scheming against keeps out the corresponding oblique tones Joints point coordinates data; Make use of pixel value to resolve the effect that hand ascertains to articulation coax before judging that hand is located in articulation coax afterwards. The form line applying distinguishes and gradation distinguishes two kinds method synthetically,the Joints has given first place to upper form line characteristic point within ascertaining the body,difference has distinguished for subsidiary,first,second mutual complement,has improved automation orientation accuracy and efficiency with gradation.Computer application studying developed the dash human body weaving in that Windows system platform working,uses Visual C + + 6.0 Joints has counted automation orientation software system originally,having realized computer automation orientation dash human body Joints in moving an image makes analytical motion picture recording system accurate coupling back motion information in time and has fine maneuverability.
