Abstract: 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.

Abstract: A vehicle service system incorporating a set of imaging sensors disposed in an inspection lane through which a vehicle is driven. A first imaging sensor is disposed with a field of view aligned to observe leading surfaces on an approaching vehicle, while a second imaging sensor is disposed with a field of view aligned to observe trailing surfaces of a departing vehicle. A processor is configured with software instructions to capture a set of images from the first imaging sensor as the vehicle approaches, and a set of images from the second imaging sensor as the vehicle departs. The processor evaluates the acquired images from the first and second imaging sensors according to a set of rules to identify images in which a license plate is present on an observed surface of the vehicle, and to extract license plate information from at least one of the identified images.
