TIRE OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/282276
Kind Code:
A1
Abstract:
A tire observation device (20) comprises: a camera (211); an imaging device (21) that includes a plurality of ranging sensors (2161U, 2161D); and an arithmetic unit (22). The plurality of ranging sensors (2161U, 2161D) are installed at different angles with respect to the surface of the ground. The arithmetic unit (22) calculates the position of a tire FT relative to the camera (211) by using a plurality of distances to the tire which are measured by the plurality of ranging sensors (2161U, 2161D). The arithmetic unit (22) uses the position of the tire (FT) to calculate amounts of adjustment of the position and the angle of the camera (211) so that the center of the imaging performed by the camera (211) is oriented toward the center of the tire (FT) or the tire (FT) surface to be measured. The imaging device (21) uses the adjustment amounts to adjust the position and the angle of the camera (211).
