WIPO Patent Application WO/2023/182515
Kind Code:

Abstract:
The present invention enables accurate and easy detection of a vehicle that passes through a prescribed area even when various vehicles pass through the prescribed area in a mixed manner. A passing vehicle detection device (1) comprises: an optical sensor (20) for irradiating the side surface of a vehicle passing through a prescribed area (A) with laser light, and detecting the reflected light of the laser light which was reflected by said side surface; and a computation processing device (41) for detecting a vehicle passing through the prescribed area (A) on the basis of the detection results from the optical sensor (20). The height of the optical sensor (20) from the ground is set such that the irradiation location in the height direction of the laser light is a height that is positioned within a range (Rh) from the center of a wheel provided to the vehicle to the apex of the vehicle.
