Document Type and Number:
WIPO Patent Application WO/2022/196766
Kind Code:
A1
Abstract:
In the present invention, a mirror device (12) is provided so as to cover the top of a test apparatus (5), which is on an inspection chamber floor surface (4), from a LiDAR device (11) so that the LiDAR device (11) does not detect the test apparatus (5). The mirror device (12) comprises: first planar mirrors (13) that extend along a horizontal plane and that have an inner edge (13a) extending to a test vehicle (1); and second planar mirrors (14) that are inclined and have an outer edge (14a) extending to side walls (2). The height and angle of each planar mirror are set so as to guide laser light from the LiDAR device (11) toward a ceiling direction. A light absorbing material (17) is adhered to an inner surface of a ceiling wall (16) and to an upper portion of the side walls (2).
