A road traffic census is an investigation to grasp the realities of road traffic in Japan, and there are the general traffic density investigation and the parking investigation. Especially, the general traffic density investigation measures various traffics of the pedestrian, the bicycle, and the car every one hour on weekday or holiday. Therefore, grasping a local environment and a local traffic density can estimate the traffic in the future by executing road traffic census. Until now, investigators manually performed the traffic. With a development of information technology, many researchers are carrying out researches that can be automatically measured using the animation filmed with the digital video camera. However, existing researches are required for huge computational complexity to realize the accurate measurement at congested time. Then there is a demand for establishment of a general-purpose method to accurately measure. Therefore, in this research, we calculated the three-dimensional coordinates of the movement body area based on corresponding points of the rough movement body area extracted with histogram of brightness. And we have developed the system that separates the movement body area from people by carrying out cluster analysis based on the three-dimensional coordinates of the movement body area, and measures a people flow based on lap probability of the movement body area.
