Problems solved by technology

[0020] When simply using the prewitt operator, it will cause misjudgment of the edge points, because the gray value of many noise points is also very large, and for the edge points with small amplitude, the edge is lost instead, and it is not isotropic same-sex

Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0040] The technical scheme that the present invention solves the problems of the technologies described above is:

[0041] The purpose of the present invention is to solve the problem that the prewitt operator has a smoothing effect on noise when using the modified prewitt operator-8 template prewitt operator to detect the edge of the image, the positioning accuracy is not high enough, and the prewitt operator is basically lost Corner information and other problems, and the present invention solves these problems through the 8-template prewitt operator, and realizes the improvement of the image recognition rate. The present invention will be described in further detail below with reference to the accompa...

Abstract

The invention requests to protect a method for enhancing edge characteristics based on an improved prewitt operator, and the improved prewitt operator-8 template prewitt operator is used for sharpening a workpiece image to obtain an edge image with a good effect, so that the quality of the workpiece image is improved. A Prewitt operator is used in a traditional method and has a smoothing effect onnoise, the positioning precision is not high enough, and the prewitt operator basically loses angular point information and is not isotropic. In order to solve the problems, the invention provides animproved prewitt operator-8-template prewitt operator. By sharpening the workpiece image by using the improved prewitt operator-8-template prewitt operator, an edge image with a relatively good effect is obtained, thereby improving the quality of the workpiece image.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to using an improved prewitt operator—8 template prewitt operators to sharpen workpiece images, obtain edge images with better effects, and improve the quality of workpiece images. Background technique [0002] Machine vision is the use of machines instead of human eyes for measurement and judgment. Machine vision mainly uses computers to simulate human visual functions, reproduces certain intelligent behaviors related to human vision, extracts information from images of objective things for processing, and understands them, and finally uses them for actual detection and control. [0003] my country's machine vision started with the introduction of technology in the 1980s, and the semiconductor and electronics industries were one of the earlier application industries, such as PCB printing, circuit assembly, component manufacturing, and semiconductor equipment. [0004] I...
