In this paper, an automatic counting method of the passing people through the gate is proposed. In the proposed method, two measurement lines are set on the floor of the inside and outside of the gate at right angle with the moving directions of the passing people. The images of the passing people are obtained in series and two space-time images are generated at each measurement line. By detecting which line the person passes early, the moving directions of the passing people are recognized. Finally, the incoming persons and the outgoing persons could be measured by counting the people data with each direction information. In this paper, we describe the algorithm of counting the passing people using the two space-time images and show some experimental results obtained by using a simple experimental system to verify effectiveness of the proposed method.
