Experimental Evaluation of Methods of Pedestrian Traffic Measurement Using Subtraction Stereo

Abstract

In this paper, we report the results of experimental evaluation for methods of pedestrian traffic measurement at the festival held in Tatebayashi, Gunma prefecture. To measure pedestrian traffics, which include the direction and the number of pedestrian, we have already proposed two types of measuring methods based on subtraction stereo. One is the tracking method using Kalman filter, which is used in uncrowded scenes. The other is the method using KLT and Voronoi diagram, used in highly dense scenes. Finally, we show the accuracy of the proposed methods used in city environments.
