Abstract
This paper describes a method of counting pedestrians by a surveillance camera at an entrance gate. The surveillance camera is set up at side of the gate and side views of pedestrians are taken to count them. The proposed method uses only pedestrians' motion to determine their walking directions and it uses the time required for the gate passages to count pedestrians. To evaluate the method, we prepared thirty-hour videos of the Open-Laboratory at October 2005 and October 2007. More than ten thousand pedestrians were taken in the videos. The experimental results show the error ratios of counting pedestrians are less than five percent for the videos. The method is low computational costs and it works at 67 fps by a note PC.
