An Automatic Counting Passers by Using Two Slanted Measurement Lines

Abstract

Counting people at gates, or at entrances of entertainment halls is considered important for office security or marketing. We propose a new method using two line images at two slanted measurement lines. By using two slanted measurement lines, the number of passers and the direction of movement of each passer are detected simultaneously. In this paper, we describe the algorithm of counting passers using the two spacetime images and show some experimental results obtained by using a simple experimental system to verify effectiveness of the proposed method.
