TLDR
In this paper, an image sensor is set at an intersection to measure traffic flow by vehicle tracking, which is done by gray level pattern matching, and then the hardware for high speed gray-level pattern matching is provided.Abstract:
In this paper, we show anew image sensor for measuring traffic flow. The image sensor is set at an intersection. The image sensor measures traffic flow by vehicle tracking. The tracking is done by gray level pattern matching. Gray level pattern matching is suitable for outdoor use since it is robust against change of scene brightness. Then we provide the hardware for high speed gray level pattern matching. After showing our new method for measuring traffic flow by the image sensor, we measure traff~c flow at an actual intersection and describe the results. The sensor measures traffic flow accurately under various conditions.read more
