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.
