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.

Abstract: A vehicle inspection system for acquiring measurements of at least one vehicle moving through an inspection lane is in communication with a remote data processing and storage system to aggregate data from multiple vehicles passing through the inspection lane, and optionally, from multiple inspection lanes. The remote data processing and storage system is configured with suitable software instructions to store the received vehicle inspection data, as well as vehicle service data received from vehicle service equipment, and to generate reports and/or respond to data queries using the stored vehicle inspection and vehicle service data.

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.
