Abstract

The invention provides a method and a system for measuring a tire. The method comprises steps of by detecting positions of a target installed on a tire of an automobile, once the position of the target on the tire of the automobile is in a shooting region, acquiring a moving image of the tire; judging feature points of the image, carrying out further analysis according to the feature points of the image and turning to measure the angle of the tire of the automobile, thereby achieving effects that angle measurement can be carried out on the tire of the automobile with no need for stopping operation of forward and backward pushing of the automobile or left and right turning of a steering wheel during a moving process of the automobile; and then, during the measuring process of the tire, requiring images without a stop, extracting feature points for analysis so that obtained data is not liable to distort, and carrying out all-directional measurement on movement and all angles of the tire of the automobile.

Description

technical field [0001] The invention belongs to the technical field of tire measurement, and in particular relates to a tire measurement method and system. Background technique [0002] In the design of modern automobiles, in order to ensure the stability and comfort of the automobile at high speed, the automobile generally adopts four-wheel independent suspension. In order to ensure that the car can automatically keep a straight line when driving, and the tires can automatically return to their positions after turning, the steering wheels of the car are designed with many angles, such as front wheel toe-in, rear wheel toe-in, front wheel camber, rear wheel camber, Front wheel kingpin caster and inclination, thrust angle, retraction angle, etc., in the actual use process, due to the replacement of tires and parts or the external force of the tires, these angles will change, and the automatic return function of the vehicle will be reduced. , affecting the straight-line drivi...
