Image accurate processing method and system for chemical fiber paper tube appearance detection

Abstract

The invention discloses an image accurate processing method for chemical fiber paper tube appearance detection. The method comprises the following steps: arranging an auxiliary mark on a chemical fiber paper tube to be detected to position an end cylindrical surface circumference of the chemical fiber paper tube to be detected; collecting the image signal of the cylindrical surface image of the chemical fiber paper tube to be detected with a detection camera; conducting training remediation on a triggering signal with a PC machine, so as to form a collection control signal; during image splicing, determining the boundaries of two adjacent images, and removing overlapped parts to realize accurate splicing of the images; finally, conducting panoramic view splicing on the signals of cylindrical surface images of different codes. The method has the advantages that not only are problems such as geometric distortion, poor precision and undesirable image splicing effect of the conventional image processing method solved, but also cylindrical surface panoramic images in different areas can be spliced accurately, thereby having the characteristics of high image processing precision, low calculation quantity, high anti-interference capability, high implementation possibility and the like.

Description

technical field [0001] The invention relates to an intelligent image processing technology used in the detection technology of industrial products, and more particularly to a method and system for accurate image processing during the appearance detection of chemical fiber paper tubes used in the appearance detection of chemical fiber paper tubes. Background technique [0002] Chemical fiber paper tubes are mainly used in the textile industry to provide basic guarantees for high-speed winding or elastic spindles. Its shape geometry, roundness, concentricity and whether the appearance is flawed are very important parameters when the paper tube acts as an intermediate medium. At present, paper tube manufacturers generally use manual inspection methods to ensure that the appearance of the output paper tube meets the quality. Require. However, the manual detection method has the following disadvantages: [0003] 1. Due to the inconsistency of subjective judgment standards among...
