Document Type and Number:
WIPO Patent Application WO/2022/028530
Kind Code:
A1
Abstract:
A calibration device, comprising a bracket (100), an image display board (200), a light projection apparatus (300) and an adjustment apparatus (400). The bracket (100) is used for carrying and installing various structures. The light projection apparatus (300) is used for projecting light to the image display board (200) so as to form a set pattern to assist in calibrating a sensor to be tested on a vehicle to be tested. The set pattern used by the calibration device to calibrate the vehicle is not formed by ink printing, but is formed by means of projecting light to the image display board (200) by means of the light projection apparatus (300), which effectively prevents ink on the edge of the set pattern from easily spreading outward and affecting the display effect of the set pattern. Further provided is a calibration method.
