MULTI OPTICAL AXIS PHOTOELECTRIC SENSOR, APPARATUS FOR RECOGNIZING SHAPE OF VEHICLE, AND CAR WASHER

摘要

PROBLEM TO BE SOLVED: To accurately discriminate an object to be detected from other parts, in the object to be detected from which an extremely small part such as an antenna is extended. SOLUTION: A vehicle shape recognition apparatus is provided with a projector 32 including a plurality of projecting elements 11 and a light receiving unit 33 including a plurality of light receiving elements 12, and configured to discriminate whether or not light is shielded for each optical axis. Then the detection sensitivity of the optical axis at the interval of a prescribed number of optical axes is set differently from the detection sensitivity of the other optical axes among a plurality of the optical axes.
