Abstract

The invention belongs to the tire production field in the chemical industry, in particular to a tire angle property detection method based on point cloud data, which comprises the following steps: 1)scanning a tire to be detected in a production line by using a three-dimensional point cloud laser imaging device; 2) positioning the tire angle position through an image processing method according to the collected tire point cloud data; 3) judging the tire angle property by calculating the main direction curvature of the tire angle position according to the scanned tire point cloud data. The invention solves the problems of low identification accuracy and large error of the tire angle property in the prior art, greatly reduces the labor intensity and improves the detection efficiency.

Description

technical field

[0001] The invention belongs to the field of tire production in the chemical industry, and in particular relates to a tire angle property detection method based on point cloud data. Background technique

[0002] In the tire production process, it is necessary to select the corresponding scraper on the production line according to the tire corner properties of the tire embryo to cut the tire corner into the shape required by the finished tire. The determination of the tire corner properties plays a decisive role in the selection of the scraper type. If the tire corner properties are judged wrong, the production line will choose the wrong scraper, which will make the produced tires not meet the requirements, and eventually lead to tire scrapping.

[0003] At present, there is no literature on tire corner property detection based on point cloud data. Contents of the invention

[0004] The purpose of the present invention is to improve the accuracy of judging ...
