Three-dimensional visual inspection system with small size and large base line distance for automobile wheel positioning parameter

Abstract

The invention discloses a three-dimensional visual inspection system with small size and large base line distance for an automobile wheel positioning parameter, which belongs to the field of automobile industry and is used for solving the problem that small structural size and high-accuracy measurement cannot be realized by a visual measuring system of a wheel positioning parameter machine. The system comprises a base (1), a right video camera (2), a right front plane mirror component (3), a right rear plane mirror component (4), a top cover (5), a bulb (6), a left video camera (7), a left rear plane mirror component (8), a left front plane mirror component (9), a mirror holder base (10), a plane mirror (11), a mirror holder top seat (12), an adjusting nut (13), a positioning knob (14) and an upright post (15). By adopting the inspection system, non-contact automatic inspection of the automobile wheel positioning parameter can be completed.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a small-sized long-baseline-distance vehicle wheel alignment parameter stereo vision detection system. Background technique [0002] In order to ensure the handling stability of the car, the installation between the wheels, steering knuckle and axle shaft of the car has a certain relative position, which is called wheel alignment. Whether the vehicle wheel parameters are accurate or not has an important impact on the driving safety, handling stability and fuel economy of the vehicle. The wheel aligner is an important testing device for checking the safety of the vehicle. At present, there are more than 30,000 wheel aligners in the country alone, and the number is increasing at an annual rate of 30%. [0003] Stereo vision measurement of wheel alignment parameters can achieve non-contact detection. The distance between the two cameras in t...
