一种基于索引空间的三维运动捕获数据检索方法
A RETRIEVAL METHOD OF 3D MOTION CAPTURE DATA BASED ON INDEX SPACE
摘要
Abstract
In order to effectively retrieve a large number of 3D human motion capture data and put it into use, this paper proposes an efficient retrieval method for the unique characteristics of 3D human motion capture data.Firstly, the original motion data dimension is reduced by key frame extraction, and then the original angle data is transformed into the feature sequence by using the customized human motion semantic feature.According to the feature sequences of all the moving segments in the database, an index space based on attitude feature is constructed.At the time of retrieval, By matching the attitude features sequentially in the index space, the matching motion fragments with the same timing are found.Experimental results show that the proposed method has better time efficiency, higher flexibility and retrieval precision than most existing methods because of better motion semantic feature extraction.关键词
