基于自适应调节脚高度阈值的脚支撑约束检测

Footplant Detection Based on Adjusting the Foot Height Threshold Automatically

根据捕捉数据的运动类型,用户指定的最小约束帧的长度l,l的最大误差η这三方面确定脚踝的高度阈值覬,若某帧脚踝的高度小于覬,则称此脚为支撑脚。从捕捉数据的第一步开始根据η调整覬动态划分支撑脚。实验表明,基于本方法得到的运动编辑后无滑步现象、运动较自然并且与用户指定的路径偏差更小,更符合用户的要求。

In this paper,we present a footplant detection method by adaptive determining foot height threshold.In ourmethod,we firstly divide one step into a number of stages,each stage has different types of constraints.Then adaptivelyelecting foot height threshold according to motion type and the length of the minimum constraint frame that designedby the user and the maximum error of to determine which foot should be planted.Finally,we verify the effectivenessof our approach from the path offset error.
