Problems solved by technology

Due to the limitation of the system structure size, the existing stereo vision detection system for wheel alignment parameters cannot realize the measurement of long baseline distance, which will lead to problems such as the decrease of system accuracy due to too small baseline distance or the failure of the system to be installed due to too large structure size.

Abstract

The invention discloses a three-freedom-degree automobile wheel positioning parameter three-dimensionalal visual flexible detection system, which aims at overcoming the problem that the three-freedom-degree regulation of an automobile wheel positioning parameter three-dimensional visual detection system can not be realized. The system comprises a bottom plate (1), a vertical guide rail (2), a slide block (3), a transverse connecting plate (4), a transverse guide rail (5), a camera assembly (6) and a plane mirror assembly (7). The system can complete the three-freedom-degree regulation of system elements in the automobile wheel positioning parameter visual detection process.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a three-degree-of-freedom automobile wheel alignment parameter stereo vision flexible 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 ...
