The paper deals with the problem of determining the instantaneous velocity of vehicles from a series of one-camera images. The model of vehicle trajectory is described, and the relationship between the image and real coordinates is expressed. Relationships are derived to obtain the necessary a priori information on the height above the road. Accuracy analysis for the designed processing method is performed.
For measuring a vehicle velocity, we can use a series (time sequence) of CCD camera. In order to calculate the velocity, we need to know a distinct point on the vehicle images to identify it in all images of the series, and subsequently transform its position from image coordinates to real coordinates. As this transformation is not generally straightforward a certain a priori information is required.
