DYNAMIC SCENE MODELING FOR AUTOMATIC TRAFFIC DATA EXTRACTION

Some aspects of the automatic analysis of real dynamic scenes related to obstacle detection for the prevention of accidents involving a trolley car driven through zones of possible conflict with other users are discussed in this paper. A new technique is described for detecting time-varying edges under nontrivial conditions. For modeling purposes, the knowledge of the boundaries of the moving objects is used to generate minimum bounding octagonal models of vehicles and pedestirans. The computational aspects associated with real-time image processing are discusssed. The effectiveness of the surveillance system is demonstrated by means of video tapes recorded at street crossings, under natural lighting condtions. Two frame sequences, where different moving objects such as pedestrians and cars, cross an urban intersection are presented.
