What Are the Advantages of Using Machine Vision for Defect Detection?

Due to the development of modern production, most of the items used in daily life are mechanically manufactured and inevitably have some defects. With the development of industry and continuous progress in science and technology, especially the rapid development of machine vision, visual product defect detection has become popular. Let's learn about defect detection.


Definition of machine vision defect detection


Defect detection usually refers to the detection of surface defects. Surface defect detection uses machine vision detection technology to detect defects such as spots, pits, scratches, color differences, and defects on the surface of the workpiece.


Machine vision defect detection projects


Defect detection projects include: product defects, product size, and product appearance.


Machine vision defect detection equipment


Currently, many software companies worldwide have developed many such testing software. The system can automatically detect and mark defective parts according to the set technical specifications, and can also sort and reject automatically as needed.


Machine vision defect detection functions


In order to meet the needs of actual production, the surface defect detection system has the following applicable functions:


  • Automatically synchronize the workpiece with the camera;


  • Automatically detect defects such as spots, pits, copper stains, scratches, bubbles, etc. on the product surface;


  • Can learn and name defect types as needed;


  • Select the defect type to be detected as needed;


  • Independently set the size of defects as needed;


  • Locate the bad area and control the labeling equipment and printing equipment;


  • Automatically store images of defective products for historical queries;


  • Automatically count (NG, OK, total, etc.);


  • Provide sound and light alarms when abnormal, and control equipment start/stop;


  • Machine vision systems have self-learning functions, and the learning process is simple. Thereby further promoting the accuracy of machine vision measurement.


Case study of machine vision defect detection applications


The defect detection system covers various major production and manufacturing industries such as food, medicine, manufacturing, 3C, automobiles and their accessories, and agriculture. With the prevalence of machine inspection system, machine vision optics has attracted increasing market attention.
