Human skeleton three-dimensional reconstruction-based sports features analysis

Author(s): Xiaocheng Sun

Sports video analysis is helpful for athlete techniques improvement, human body threedimensional reconstruction on key motions can effective help coaches and athletes to make progress. The paper firstly states human body sports capturing and threedimensional reconstruction research background and research status. And then, start from human skeleton three-dimensional reconstruction feature points extraction and matching algorithm, detail Harris Corner algorithm application in moving image feature point extraction, and make principle statements on human skeleton three-dimensional reconstruction’s initialization process and basic matrix refining process. Finally, apply Harris Corner algorithm, eight-point algorithm, gold standard algorithm, Sampson correction algorithm and linear triangular algorithm to carry on feature point extracting 、matching and three-dimensional reconstruction to do experiments on men aerobics and men martial arts events one frame image, finally it gets relative satisfied experiment result.
