ABSTRACT:
The method for measuring speed is performed by dividing the time sequence image data A into long and narrow frames (step401). Next, the framed images and the time sequence image data B produced by the line scan camera B are correlated to obtain a moving time (step402). Next, a moving time of each framed image and a corresponding moving distance are obtained to compute a moving speed (step403). Next, scale of a specific shape pattern and the like is corrected using the moving speed obtained to match the scales in the two image sequences A and B to obtain a similarity degree (step404). Next, a threshold value is applied to the similarity degree to recognize the specific shape pattern, thereby recognizing that the images are produced by a moving vehicle.
