Abstract: Multiple objects tracking is the basic and important problem in intelligent visual surveillance system. It is difficult to track multiple objects under occlusion only using two-dimensional visual features. Recently, the three-dimensional tracking system becomes the hot point, which can utilize three-dimensional features to recognize and track objects even under occlusions, and improve the accuracy of intelligent visual surveillance system entirely. The methods of tracking multiple objects based on three-dimensional visual system are introduced, which can be divided into three classifications described in detail. The merits and drawbacks of representative methods of each classification are introduced, and the future application and research trend is discussed.

Key words: multiple objects tracking, visual surveillance, three-dimensional visual modeling system
