説明
This paper deals with distinguishing vehicle types in the automobile traffic flow by image processing. In the traffic flow, a traffic jam always occurs. The traffic jam gives a driver's burden and it results in time-delay, a traffic accident, and air pollution. In that case, it is important to offer the traffic information such as vehicle volume and the distinction of vehicle types. In this paper, we attempt to do them using a value of vehicle width.<br>The general measurement method of traffic flow is done using an ultra sonic sensor. But the system is expensive, and the method is not useful for automobile traffic flow. Thus, we have developed the simple system using a portable camera, a personal computer, and DSP. This system makes the width measurement of vehicles in real time. The measurement method uses Fourier transform, and takes an advantage of robustness for noise. Taking into consideration that frequency analysis for width measurement on vehicle image differs from it on road image, we will measure vehicle volume and distinguish vehicle types in real time.
