Abstract
An image capture device captures a plurality of sequential images of a vehicle in motion. At substantially the same time a collocated rangefinder determines the distance between the vehicle and the image capture device. Each of the plurality of images may be segmented based on the rangefinder point of reference. The portion of each image representing the vehicle is extracted based on its motion with respect to a stationary background. Knowing the size of the vehicle with respect to the image and the distance that the vehicle is from the image capture device, the image data is converted to real world dimensions. Using these real world dimensions a vehicle classification is determined.
