【概要描述】With the development of industrial automation, the application of industrial machine vision system will also be more and more extensive. In addition, the rapid development of digital image sensors, CMOS and CCD cameras, DSP, FPGA, ARM and other embedded technologies, image processing and pattern recognition technologies will also bring a huge boost to the development of machine vision inspection. Here is a brief introduction of the main components of industrial machine vision system: 1. Camera and optical components This category usually contains one or more cameras and lenses (optical components) for photographing the detected object. According to the application, the camera can be based on the following standards: black and white, composite color (Y/C), RGB color, non-standard black and white (variable scan), step scan or line scan. 2. Lights The light of industrial machine vision system is used to illuminate components, so as to capture better images from the camera. The light system can be in different shapes, sizes and brightness. The general light forms are high-frequency fluorescent lamps, LED, incandescent lamps and quartz halide optical fibers. 3. Component sensor It usually appears in the form of grating or sensor. When the sensor senses that the component is close, it will give a trigger signal. When the component is in the correct position, the sensor will tell the machine vision system to collect the image. 4. Image acquisition card Also known as video capture card, this part is usually a card inserted on the PC. The function of this capture card is to connect the camera with the PC. It obtains data (analog signal or digital signal) from the camera and then converts it into information that the PC can process. Industrial machine vision system can also provide signals to control camera parameters (such as trigger, exposure time, shutter speed, etc.). There are many types of image capture cards, Support different types of cameras and different computer buses.

随着工业自动化的发展，工业机器视觉系统应用面也将越来越广泛，加上数字图像传感器、CMOS和CCD摄像机、DSP、FPGA、ARM等嵌入式技术、图像处理和模式识别等技术的快速发展，也为机器视觉检测发展带来巨大的助推力，下面为大家简单介绍工业机器视觉系统的主要组成：

　　1.摄像头和光学部件

　　这一类通常含有一个或多个摄像头和镜头(光学部件)，用于拍摄被检测的物体，根据应用，摄像头可以基于如下标准，黑白、复合彩色(Y/C)，RGB彩色，非标准黑白(可变扫描)，步进扫描或线扫描。

　　2.灯光

　　工业机器视觉系统灯光用于照亮部件，以便从摄像头中拍摄到更好的图像，灯光系统可以在不同形状、尺寸和亮度，一般的灯光形式是高频荧光灯、LED、白炽灯和石英卤(quartz-halogen)光纤。

　　3.部件传感器

　　通常以光栅或传感器的形式出现，当这个传感器感知到部件靠近，它会给出一个触发信号，当部件处于正确位置时，这个传感器告诉机器视觉系统去With the development of industrial automation, the application of industrial machine vision system will also be more and more extensive.
