Tire inner wall texture identification method based on locating block

Abstract

The invention discloses a tire inner wall texture identification method based on a locating block. The tire inner wall texture identification method based on the locating block includes steps: obtaining a coordinate of the locating block of an image frame, and transforming an original image at any angle into a standard front view by employing a transformation model; obtaining a static texture description by employing a static texture model through image enhancement; and performing texture identification on sampled images. According to the method, the standard front views can be obtained by transformation of the images with different angles by employing a transformation method, the fact that static texture presents the same characteristic in time and space is researched, a dynamic problem is changed into a static problem, a group of static texture models are obtained for the static texture, matching and identification with a database are performed so that rapid texture matching is realized, and the effect is obvious by employing voting and marking with the combination of various methods.

Description

technical field [0001] The invention belongs to the technical field of video processing and analysis, and in particular relates to a tire inner wall texture recognition method based on positioning blocks. Background technique [0002] Static texture refers to the inherent texture of the surface of the object in the usual sense, including uneven grooves on the surface of the object, and also includes color patterns on the smooth surface of the object, which exist widely in nature, such as artificial artworks (walls, Graffiti and patterns on train and subway surfaces, rugs, sweaters, and other fine arts and crafts include geometric patterns in various formats), cracks, tire patterns, and more. Texture recognition is to perform feature extraction, description and analysis through texture, and correctly classify different types of unknown textures into known texture types. Static texture recognition has a wide range of application prospects. It enables us not only to distinguish...
