Footplant detection based on adjusting the foot height threshold automatically

Abstract

In this paper, we present a footplant detection method by adaptive determining foot height threshold. In our method, we firstly divide one step into a number of stages, each stage has different types of constraints. Then adaptively electing foot height threshold according to motion type and the length l of the minimum constraint frame that designed by the user and the maximum error φ of l to determine which foot should be planted. Finally, we verify the effectiveness of our approach from the path offset error. © Springer-Verlag Berlin Heidelberg 2013.
