For augmented virtual environment(AVE) video surveillance system,a moving target retrieval method based on trajec-tory constraints using target's 2D image feature and 3D Temporal Spatial feature is proposed in the paper.Firstly,SURF features are used for accurate positioning of target during two-dimensional retrieval process.Secondly,as for three-dimensional retrieval,the computing method of moving block's TemporalSpatial Feature for AVE surveillance system is also elaborated,then making the full use of associated information for relational...
