The process of image data processing is generally called (), and the software and hardware system used is called photogrammetry system.

The process of image data processing is generally called (indoor production), and the software and hardware system used is called photogrammetry system.

The image system consists of image processing software, CCD camera, CCD lens, image acquisition card and computer (industrial computer). If there is a motion platform, it is necessary to add a motion control system unit, but at this time the system is no longer called an image system, but a machine vision system.

Basic definition

Image system is commonly known as CCD system or vision system in industry.

System principle

The core of image system is image processing software, which is usually called visualization software in industrial automation. When working, the CCD camera takes pictures of the products and sends them to the image acquisition card, which converts the signals into digital signals and sends them to the computer. The image processing software then analyzes, locates and identifies the collected data, and returns the coordinate values, proportions, angles and other parameters of the product to the user.

core technology

The core part of the image system is the image processing unit, which includes BLOB analysis, object counting, geometric matching, gray matching, character recognition, bar code recognition, circle measurement, caliper measurement, external meridian measurement, color recognition, basic image operations (binarization, proportional transformation, open operation, closed operation, expansion, corrosion, filtering) and other functions. The famous foreign companies devoted to image algorithm include NI Company of the United States and cognex Company.

System application

Imaging systems have been widely used in measurement, monitoring, medical treatment, sensors, industrial smart cameras, visual tracking and navigation devices, industrial automation equipment and other fields, among which medical applications are mainly in developed countries abroad, and domestic applications are relatively few.

development prospect

With the development of China's economy and the improvement of people's living standards, more stringent requirements are put forward for the products produced by industry. In the case that manual work can't meet the requirements of product monitoring, the image system will replace manual work for product factory control, while the high-end image system will monitor the products with high quality and the fiercest market competition.

At the same time, the improvement of efficiency will greatly save the production cost of enterprises. Therefore, the development prospect of imaging system technology in the next decade will be widely used, and some production enterprises that use a lot of manual labor and have low production efficiency will face elimination.
