Quan-zhou　chest-clapping　dance　is　one　of　the　national　intangible　cultural　heritages　of　China,　and　the　motion　capture　technique　is　an　important　method　to　realize　its　protection　and　inheritance.　In　this　paper,　we　present　the　automatic　segmentation　technique　of　the　motion　capture　data,　in　which　the　motion　data　is　automatically　segmented　through　KPCA　combined　with　PPCA　to　reduce　the　dimension　and　project　the　56　dimensional　data　in　2　dimensional　space;　formulate　the　feature　function　to　obtain　the　derivative　of　projection　error,　detect　the　segmentation　point　of　data　through　analyzing　the　change　of　geometric　features　to　realize　the　automatic　segmentation.　It　is　indicated　in　the　experiment　that　the　motion　capture　technique　has　certain　feasibility.　©　2015　Taylor　&　Francis　Group,　London.
