POSITIONING APPARATUS AND POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/241263
Kind Code:
A1
Abstract:
A positioning apparatus (100) and a positioning system, in the technical field of calibration. The positioning apparatus (100) comprises a first detection unit (10), a second detection unit (20), and a processing unit (30); the first detection unit (10) and the second detection unit (20) are located at two sides of a vehicle (102), respectively; each of the first detection unit (10) and the second detection unit (20) comprises an image acquisition assembly, the image acquisition assembly comprising a first wheel camera (12) facing the direction of a first wheel (1022) of the vehicle (102), and a calibration frame camera (14) facing the direction of a calibration frame (101); the processing unit (30) is connected to each of the first detection unit (10) and the second detection unit (20), and the processing unit (30) is used to control the two first wheel cameras (12) to acquire first images of the first wheels (1022) on both sides, respectively, and is used to control at least one of the two calibration frame cameras (14) to acquire a second image of at least part of the calibration frame (101); the processing unit (30) is also used to determine the position of the calibration frame (101) relative to the vehicle (102) according to the first image and the second image. The positioning apparatus (100) may improve calibration precision and calibration efficiency, and improve maintenance efficiency.
