Problems solved by technology

[0003] Machine vision is used more and more in the field of automation. Many software developers use machine vision libraries provided by visual processing software such as Halcon and OpenCV to perform recognition. Unfortunately, due to machine vision applications, lighting, surrounding environments, etc. The impact is very large, which makes it impossible to extract a suitable reference template, which ultimately affects the recognition effect

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] Such as figure 1 Shown is a schematic diagram of the steps of the present invention.

[0045] An image processing method for a visual detection system, the visual detection system includes a camera for collecting images, the collection effect is good, and it is easy to use, image processing software for processing images, and comparison processing software for comparison processing, the comparison processing The software stores the original image, and compares the original image with the comparison image to judge whether the position is consistent, with a high degree of automation;

[0046] Image processing methods are:

[0047] Step 1. Obtain the image to be processed through the camera. The camera takes the image of the material position to form an image, which is easy to use and high in work efficiency; obtains the moving or stationary material through the ...

Abstract

The invention relates to the technical field of visual inspection processing, in particular to an image processing method for a visual inspection system. The visual inspection system comprises a camera for collecting images, image processing software for processing the images and comparison processing software for comparing and processing, wherein the comparison processing software stores the original images. The image processing method comprises the steps of obtaining the to-be-processed images through the camera, intercepting parts, containing a material, of the images, processing the images through the image processing software, drawing the outline of the target material, recording breakpoint positions of each line section of the outline, the positions of the centers of circles and the radii of the circles, producing a DXF file containing the above line sections and the circles, importing the DXF file into the comparison processing software, and using the images of the DXF file as comparison images. The image processing method for the visual inspection system is high in working efficiency, comparison efficiency and judgment efficiency.

Description

technical field [0001] The invention relates to the technical field of visual detection processing, in particular to an image processing method for a visual detection system. Background technique [0002] Machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system refers to converting the target to be detected into digital signals through machine vision products (ie, image capture devices, such as CMOS and CCD), and these digital signals are then sent to dedicated image processing systems (sub-embedded and video card methods) ), the image processing system sets the detection task according to the task requirements to be detected. Then, according to the result of the discrimination, the equipment actions on the spot are controlled. [0003] Machine vision is used more and more in the field of automation. Many software developers use machine vision libraries provided by visual processing software such as Halcon and Open...
