A Multi-Pedestrian Counting System Using Fusion of Stereo Camera and Laser Scanner

In Phase I, we developed a new system for pedestrian detection, tracking and counting. In this system, both IR LED stereo camera and laser scanner were selected for use. We have demonstrated that our pedestrian counting system can count multiple pedestrians walking in a large group, maintain individual tracks even when some pedestrians walk in unpredictable patterns or leave the crosswalk prematurely. Although we are able to reachover 90% accuracy of multi-pedestrian counting in a realistic environment, in Phase II, we will further improve the system developed in Phase I. We will focus on the system performance issues in terms of near 100% counting accuracy. We will also improve the algorithm computation speed to meet the near real-time requirements. Our primary goal in Phase II is to develop one commercial product for the pedestrian counting at street intersection. There are a number of components in this product suite, including IR LED IP stereo camera, powerline networking, laser scanning device with network capability, software driver to interface with a third party traffic controller, NTCIP compliant remote data access software tools using media streaming, and new intersection performance measures.
