Measur ement and Identification of Moving Object Flow Using Digital Video Camer a

Abstract

To decide a road maintenance plan, it is necessary to predict future traffic volume of the road by analyzing and understanding the present traffic volume. Currently, investigators measure the traffic volume manually using counters. Recently, with the development of information technology, automatic measurement using a digital video camera has been undertaken experimentally. However, this method is not able to accurately measure the flow of a moving object in the case where another objects exist and thus, automatic measurement of the flow of a moving object has not yet to be realized. In this research, the direction vector of a moving object is calculated. The moving object is identified based on angle and size of the direction vector. In addition, based on the results of identifying the moving object accurately, the flow of pedestrians is accurately measured.
