Xinxiwang Class - What is a visual inspection system?

he full name of visual inspection is "machine vision inspection system", which mainly collects images from the camera, analyzes and calculates the vision system, and compares it with the limit sample to determine whether it is defective.

Composition of the inspection management system for vision technology

Generally speaking, a visual inspection system includes a lighting system, a lens, a camera system, a capture card, an image processing card, and an image processing system. For each application, we need to consider the speed of the system and the speed of image processing, whether to use a color or monochrome camera, to detect the size of the target or whether to detect defects, how high the field of view needs to be, and how much contrast the resolution needs.

Functionally, the analysis of a typical visual inspection management system can be divided into three parts: image acquisition part, image information processing part and motion control part.

Design of a visual inspection system

The design of the visual inspection system is divided into software design and hardware design.

1. The hardware of the visual inspection management system is designed

The hardware of the visual technology inspection management system is mainly composed of lenses, cameras, image data acquisition cards, input signal output units, and control devices. The quality of a set of visual inspection and analysis system depends on the level of camera pixels, the quality of the hardware environment, and more importantly, the mutual cooperation and reasonable selection and use of various components.

2. Software design of visual inspection system

The software engineering design of the visual inspection management system is a very complex topic, which should not only consider the optimization of the program design, but also the effectiveness of the algorithm, and whether the enterprise can take into account the problems that may arise in the process of software product design. After the software development and design of the visual information system is completed, its robustness should be analyzed, tested and improved to adapt to the complex external market environment.

How a visual inspection system works

The visual inspection and image acquisition hardware mainly consists of two visual processing units and an image-to-digital converter and frame memory acquired by the lighting system, vision sensors, analog acquisition, and other components.
