Embodiment Construction

[0037] figure 1 It is a system schematic diagram of an embodiment provided by the present invention. This system is mainly composed of image acquisition from CCD, primary color selection, binarization, primary filtering, image analysis, and secondary filtering.

[0038] figure 2 Flow chart for CCD paper detection. The CCD static paper detection system uses CCD to take the paper image into the computer and converts the image into a digital signal, that is, the computer image is composed of many pixels, and then these pixels are analyzed through computer software to detect the black spots on the paper And transparent dots, etc., count the number and area of ​​black dots and transparent dots on the paper, compare the paper standards stored in the computer in advance, automatically classify the paper quality, and automatically alarm for unqualified paper, and automatically calculate it The failure rate of paper and the proportion of paper at all levels, the working principle and fl...

Abstract

According to the invention, a CCD paper defect detection system based on image pattern recognition is designed according to a paper quality grading method. According to the invention, with a CCD technology, paper surface quality is subjected to real-time detection and dynamic measuring; the paper products are automatically classified according to the qualities, and paper defects such as black spots and holes on the paper surfaces are detected; the papers are automatically classified, and alarming is performed when unqualified papers are detected; and a failure arte of the papers and a proportion of each grade of the papers can be obtained by automatic calculation. Therefore, detection efficiency is improved, and various data of the papers is automatically counted.

Description

technical field [0001] The invention relates to pattern recognition, more specifically, to a paper defect testing system based on image pattern recognition. Background technique [0002] At present, there are many manufacturers of paper, but they all suffer from the lack of a good method to carry out quality inspection on the appearance of the produced paper. Many of them still carry out sampling inspection manually, which is time-consuming and laborious. The CCD static paper detection system uses CCD to capture the paper image into the computer, and then automatically analyzes the paper image through the computer to detect black spots and cavities on the paper, and can automatically classify the appearance quality of the paper. For unqualified The paper can automatically alarm, and can automatically calculate the unqualified rate of paper and the proportion of paper at all levels. This not only improves the detection efficiency, but also can automatically count various dat...
