Abstract

This paper proposes a pedestrian counting system using line laser. By using a line laser and IR filter, the shapes of pedestrians are easily obtained without complex preprocessing. Also, the directions of pedestrians were able to distinguish by employing gradient information. In the experiment, the proposed method successfully counted the number of people with accuracy of about 97% and with processing time of 24ms per frame.
