摘要 阐述了一种适用于被动式光学人体运动捕捉散乱数据处理的方法,该方法基于模版匹配的原理,根据人体标示的特征点的局部相对刚性结构以及整体拓扑结构关系,利用刚性结构匹配、运动轨迹追踪、拓扑结构校验实现散乱数据的处理,从而得到人体运动参数及骨架拓扑结构。该方法解决了追踪算法在特征点重合时的追踪出错问题,处理方法经优化后数据处理过程能够满足运动捕捉的实时性要求,具备错误自动检测和纠正能力,处理过程无须人工干涉。 An approach of scattered data processing for passive optical motion capture was proposed.The approach is based on the principle of model matching.Based on rigid construct matching,tracking and topology checking,the parameters of motion could be obtained and the topologic model of human could be constructed according to character markers,local rigid structure and global topologic relation.This method avoids the error of tracking method when two or more markers overlap. Due to the ability of checking and rectifying error,the data processing is in real time and needs no manual works.
