This paper presents a method of pedestrian counting using an IR line laser. In the proposed method, only reflection of IR line laser onto pedestrians is obtained using an IR filter. Hence acquisition of moving object images is extremely simple and reliable compared to other vision-based method. The number of pedestrians is counted using simple blob analysis and their moving directions are obtained from slopes of the blobs. Experiments showed that the proposed method is able to count the number of pedestrians effectively (with accuracy of about 95%) and efficiently (9ms for one frame on a standard PC).
