摘要
基于光学的运动捕捉越来越受到人们的重视,但是将捕捉到的Marker点空间位置转换成为人体运动参数的精确性和快速性还是问题,其中关节中心的估算是问题的关键。基于Marker和关节中心之间的刚体特性,运用最小二乘法,并针对具体系统进行适当调整,建立了一种Full_Marker_Joint关系模型,精确而快速地实现了关节中心的判定,达到了较好的效果。
The Motion capture technology based on optics has attracted more and more attention. But the precision and speed in converting from the marker space position to human motion parameters is still a problem, in which estimating the center of the joint rotation is the key duty. It is focused on the solid relationship between marker and its relative joint center, adopted the MSQ methodology, and adjusted the material algorithm according the factual system. At last, a Full_Marker_Joint relationship model is established, the precise and rapid judgment on the joint center is realized, and a better result is achieved.
