Embodiment 1

[0037] refer to Figure 2~Figure 4 , figure 2 For the full-page rivet image, the rivet visual detection method provided by the present invention is used for visual detection, and the obtained image 3 , Figure 4 result. in, image 3 Using the matching score, contrast, etc. as parameters, using methods such as edge contour extraction, shadow area, etc., to obtain the visual detection results of A rivets, the white circle in the figure is the position of A rivets detected by this rivet visual detection method; Figure 4 Using the matching score and contrast as parameters, using methods such as contour comparison and auxiliary masking, the visual detection results of B rivets and the absence of rivets are obtained. The white circle in the figure is the B rivet position detected by this rivet visual detection method, and the black circle is The rivet missing position detected by the rivet visual inspection method.

[0038] The above experimental results show that the method...

Abstract

A visual detection method for rivets. SVRD's image-centric user interface and drag-and-drop interaction method provide users with a simple and efficient workflow, simplify the complexity of the system, and reduce the technical requirements of operators. The system Rich measurement operators are integrated, and operators such as position matching, shape matching, and spot detection can be used to detect whether there are shortages, wrong materials, and out-of-position installation conditions of rivets. SVRD has been introduced and applied in batches in the rivet parts production industry.

Description

technical field [0001] The invention relates to the technical field of machine vision image recognition, in particular to a rivet visual detection method. Background technique [0002] In the global processing industry, China can be described as a big manufacturing country, known as the "world factory". With the intensification of global competition, China's manufacturing industry has made great progress. Exquisite design, complex craftsmanship and strict quality requirements have brought huge challenges to the production of processing plants. Reducing the generation of waste products and improving quality control capabilities have become an important issue for processing plants. At the same time, users have higher and higher requirements for product indicators. The following are customers' technical requirements for software [0003] Detect defect content: [0004] 1) Whether the rivets are missing; [0005] 2) Whether the rivet is installed in an abnormal position, su...
