Motion capture database searching method based on dynamic bending algorithm

Abstract

The invention discloses a motion capture database searching method based on a dynamic bending algorithm. The method includes selecting proper motion characteristics to build a primary index and a secondary index of a motion capture database in advance, and the speed for example searching is improved. The primary index comprises motion moment attitude information. Calculation of the secondary index is based on gesture variation of skeleton motion dynamic characteristics, namely the Euclidean distance of characteristic included angle vector of the adjacent frames is utilized as the index value, and finally the dynamic time bending algorithm with the lower bound function is utilized to calculate the similarity between the searching example and the candidate segment. By means of the method, motion capture data searching is achieved accurately and quickly, the searching accuracy is improved, and the searching time is shortened.
