摘要 在光学式运动捕捉系统中,标记点往往会出现近似或对称的分布结构,这使得在对标记点进行识别时容易引起混淆。基于模板匹配的人体运动捕捉数据处理方法根据人体局部刚性结构把人体模板分割为多个子模板,使用空间仿射变换从运动捕捉数据中搜索与相应子模板误差最小的匹配点集作为最优匹配,并通过标记点跟踪实现对散乱数据的识别,解决了因标记点分布结构近似或对称而引起的混淆。对标记点缺失情况进行了重构。当出现错误匹配时系统能够自动检测并更正,整个过程无需人工干预。实验结果表明该方法能够正确识别标记点,标记点缺失情况重构效果比较理想,能够满足实时处理要求,证明了该方法的有效性。 In optical motion capture system,markers may be easily confused because of the approximate and symmetrical distributing structure.An approach based on template matching was proposed for the processing of human motion data.The human template was segmented to several rigid sub-templates by the local rigid structure.Matching point-set with least error was searched for each sub-template from the human motion capture data by affine transformation,and the scattered data was identified by point tracking.The ambiguity of identification was notability reduced.The missing data is reconstructed and when error matching is encountered the system is able to check and rectify them automatically.Manual intervention isn't necessary through the whole process.Experiment results indicate that this approach is able to identify the markers correctly,the reconstruction of the missing data is ideal and the processing is in real time.All these prove that the approach in this article is available.
