A vehicle service system incorporating a set of imaging sensors disposed in an inspection lane through which a vehicle is driven. A processor is configured with software instructions to capture a set of images from the set of imaging sensors and to evaluate the captured images according to a set of rules to identify images in which a license plate is visible on an observed surface of the vehicle. The processor is further configured with software instruction to extract license plate information from the identified images, assign a figure of merit to the extracted information, and generate an output in response to the assigned figures of merit.
