Abstract: An imaging sensor observes a field of view through which a vehicle passes, at an orientation and position suitable for acquisition of license plate data from a surface of the vehicle. Responsive to the vehicle position, at least one image of a surface of the vehicle including a license plate is acquired and evaluated to extract license plate data. The position of the vehicle for acquisition of the image is established by a trigger in a fixed relationship with the imaging sensor.
