Abstract
A real-time people counting system using ranging technology with human head-shoulder profile is discussed in this work. To obtain the profile, the system is installed above an entrance/exit gate with vertically downward view. Line structured light is used to detect the height of a person’s head-shoulder. Compared with imaging- processing approaches, this method is cost-effective, computationally simple, and more accurate. The system can also detect the walking direction of each person using a second structured illumination light source.
