The visual measurement system is a high-precision measurement system that uses optical components and image processing technology to achieve measurement and analysis. Its main components include: visual light source, industrial lens, industrial camera, image processing software, etc. Each part has different functions.

1. Visual light source: The function of the light source is to provide sufficient light so that the object to be measured presents a clear image on the industrial camera. The type of light source and illumination method can be selected according to needs.

2. Industrial lens: The function of the industrial lens is to form a clear image of the object to be measured on the industrial camera. According to different measurement requirements, different types and parameters of lenses need to be selected, such as zoom lenses, FA lenses, telecentric lenses, etc. .

3. Industrial camera: The function of the industrial camera is to convert the image of the object to be measured into a digital signal and transmit it to the computer for processing. According to different measurement requirements, industrial cameras with different resolutions and frame rates need to be selected.

4. Image processing software: Image processing software is the core part of the visual measurement system. It includes various image processing algorithms and software tools for processing and analyzing the acquired images to extract the required information. For example, image filtering, edge detection, sub-pixel edge positioning, feature extraction and other algorithms.

Each part of the visual measurement system has different functions, and together they complete the task of image acquisition, processing, and measurement analysis of objects. The system has the characteristics of high precision and high reliability, can achieve high-precision non-contact measurement, has the advantages of fast, accurate and non-destructive, and has been widely used in the field of modern industrial inspection.
