Embodiment Construction

[0044] like figure 1As shown, the vehicle wheel alignment detection system of the present invention includes a target 10 that can be fixed on the vehicle wheel, a light emitting device (not shown), an image acquisition device 20, an image acquisition and processing device 30 connected to the image acquisition device 20 and an output device 40 .

[0045] like figure 2 As shown, the target 10 has a target surface 12 for receiving and reflecting the light emitted by the light emitting device. The target surface 12 can be in any shape, and a mark is set at the center (of course, the mark can also be set at other positions on the target surface); a plurality of feature points are also designated on it. The target 10 can also be provided with a specular reflective layer on the target surface 12 to ensure the intensity of reflected light. In this embodiment, the target 10 can be fixed on the wheel of the car through the wheel clamp 11. The wheel clamp 11 has a plurality of clampi...

Abstract

The related position detection method for vehicle wheel comprises: fixing the target on the wheel, moving vehicle to obtain the target trace data by an image acquirement device; determining the real trace of the target by the image acquirement and process device and the wheel position data. This invention is simple, convenient and well accurate.

Description

technical field [0001] The invention relates to the technical field of automobile detection, and more specifically, relates to an automobile wheel alignment detection method and system. Background technique [0002] Automobile wheel alignment, such as four-wheel alignment, refers to the relative position of automobile wheel installation, which is expressed by the relative angle and position parameters between the automobile suspension system and various moving parts, including wheel camber, toe angle, and kingpin inclination , caster angle, wheel geometric centerline, thrust angle, wheel lateral offset, wheel longitudinal offset, etc. Automobile wheel alignment detection is used to detect the state of automobile wheel alignment to ensure correct wheel alignment, so as to ensure the stability of straight-line driving and light steering of the car, and reduce the wear of tires and steering parts during driving. [0003] The traditional vehicle wheel alignment detection method...
