Abstract

The present invention discloses a tire impression depth data processing method, system and device. The method comprises: collecting a plurality of light bar images by projecting on a tire through a laser beam; obtaining the first coordinates of each pixel point on the light bar in each light bar image, wherein the first coordinates are a two-dimensional coordinates of each pixel point on the light bar; performing coordinate transition of the first coordinates of each pixel points to obtain second coordinates of the collection points on the tire, wherein the second coordinates are three-dimensional coordinates, and the pixel points are in one-to-one correspondence with the collection points on the tire; and determining the impression depth data of the tire according to the height dimension in the second coordinates. The problem is solved that the measurement precision of the impression depth data of tire measurement is low in prior art, and the measurement precision of the impression depth data of tire measurement is improved.

Description

Technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a method, system and device for processing tire indentation depth data. Background technique [0002] During the turn-up process of the tire building drum, due to the influence of the mechanical design parameters of the building drum or the roller pressure, a relatively deep indentation will be formed on the surface of the tire. This indentation cannot be effectively removed after the rubber is vulcanized. Tire quality also affects aesthetics. By obtaining tire indentation depth information, the design of the building drum can be improved. In the prior art, the measurement of the indentation depth on the tire surface is mainly to measure the indentation depth by using a traditional contact measurement method to directly measure the indentation depth. This measurement method is simple to operate, but has disadvantages such as low measurement accuracy, inaccurate positioning, a...
