China has become the most active region in the world for the development of machine vision , and its application scope covers various industries of the national economy such as industry, agriculture, medicine, military, aerospace, and meteorology.
Machine vision is to use machines instead of human eyes to make measurements and judgments. machine vision system refers to converting the captured target into an image signal through a machine vision product (i.e., image capture device, divided into CMO and CCD), and transmits it to a dedicated image processing system, based on pixel distribution, brightness, color and other information , into digital signals; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions based on the discrimination results.
The hardware structure of a general machine vision system includes three parts: camera, lens and light source.
Advantages of machine vision
1. Clearer details
Compared with the human eye, machine vision has a higher magnification and can grasp the details of products more accurately.
Detection of 3mm resistor
2. Image capture is faster and more stable
Compared with manually using a microscope or other observation equipment to detect details, the optical system of machine vision can quickly and stably capture images at a set speed after debugging.
3. Perception is more objective and subjective errors are reduced.
Machine vision compares features within the software, quantifies the detection standards, and strictly implements them. The detection is more objective and is not interfered by emotions such as subjective fatigue.
