Behind the windshield camera-based perception system for autonomous traffic violation detection

A license plate recognition (LPR) camera assembly, comprising:

• an LPR camera housing containing one or more LPR cameras configured to capture videos containing one or more license plates of one or more vehicles involved in a traffic violation event;
• an LPR camera mount coupled to the LPR camera housing and configured to mount the LPR camera housing to an interior of a carrier vehicle at an angle with respect to a windshield of the carrier vehicle;
• a plurality of infrared (IR) lights configured to illuminate an event scene of the traffic violation event;
• and
• at least one LPR camera skirt coupled to and protruding outwardly from the LPR camera housing, wherein the at least one LPR camera skirt is configured to prevent reflected IR light from interfering with the videos captured by the one or more LPR cameras,
• wherein the at least one LPR camera skirt comprises an outer LPR camera skirt and an inner LPR camera skirt at least partially shrouded or surrounded by the outer LPR camera skirt,
• wherein the outer LPR camera skirt comprises a first outer camera skirt lateral side and a second outer camera skirt lateral side,
• wherein the inner LPR camera skirt comprises a first inner camera skirt lateral side and a second inner camera skirt lateral side, and
• wherein the length of at least one of the second inner camera skirt lateral side and the first inner camera skirt lateral side is determined based on an angle made by the second outer camera skirt lateral side and a windshield of the carrier vehicle.
