| Summary: | 碩士 === 遠東技術學院 === 機械研究所 === 92 === The motion analysis systems are the main auxiliary tool of exercise training, where the cinematography is an important method. This method is using the high-speed camera composed of a force measurement plate to analyze the relationship of athlete. In the experimental processes, the pictures were catching and analyzing off line. It exist some drawbacks, such as, the calibrations of camera and space are absent, and the auto pick function also absent. They will lead some error of calibration and manual operation in the experimental processes.
In this study, a feasible structure of camera based is used to enhance the drawbacks mention above. Three parts are described as following:
(1)Auto-pick of body knuckle: The processes are used band with different colors to wind body knuckle of testing athlete. By means of image processing, the center of band will be obtained. Therefore, the motion of athlete will establish according to the series of center point obtained above.
(2)Construct of three-dimensional space: The main method is using epipolar geometry to find out the corresponding points of right and left sides. Therefore, two two-dimensional images captured by two CCDs can construct a three-dimensional space.
(3)Construct coach system: When the functions of auto-pick and trajectory identification are constructed, the qualifization and quantization reports will create in this system. It will provide a useful report for increasing exercise and catch interconnection, and enhance the efficiency of training of exercises.
In this project, an auto-pick function of athlete’s motion will obtain, and a motion analysis system with accuracy and easy operation will develop. This structure can also extend to other sports, it will helpful for training of coach.
