Title:
VEHICLE INSPECTION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/080091
Kind Code:
A1
Abstract:
The present invention makes it possible to automatically perform an appearance inspection of a vehicle moving in two directions with minimal increase in cost. One preferred aspect of the present invention is a vehicle inspection device comprising a first speed measurement means, a second speed measurement means, a one-dimensional sensor, and a control device, wherein the one-dimensional sensor measures a moving vehicle a plurality of times along a direction intersecting the moving direction and obtains inspection information including two-or-more-dimensional information on the basis of the measurement result. In this device, the inspection information can be obtained both when the vehicle moves in a first direction and when the vehicle moves in a second direction opposite to the first direction, and the second speed measurement means has higher accuracy than the first speed measurement means. If the speed information of the vehicle is not measured by the second speed measurement means and is measured by the first speed measurement means, the control device performs control in a first control mode in which the measurement timing of the one-dimensional sensor is controlled on the basis of the speed information obtained by the first speed measurement means. If the speed information of the vehicle is measured by the second speed measurement means, the control device performs control in a second control mode in which the measurement timing of the one-dimensional sensor is controlled on the basis of the speed information obtained by the second speed measurement means.
