1. What is machine vision , What is machine vision system

Machine vision is to use machines instead of human eyes to measure and judge ; Machine vision system is to automatically receive and process the image of a real object through optical devices and non-contact sensors , Through analysis （ Various operations ） Get the information you need （ Characteristics of the target ）, And then control the action of field equipment .

2. The relationship between machine vision and computer vision

 3. digital image processing （DIP）

Digital image processing is to remove noise from the image by computer 、 enhance 、 Restore 、 Division 、 Methods and techniques of feature extraction .

4. Robot visual servo system consists of

 5. Hardware composition of robot vision system

The machine vision system consists of ：

        The light source 、 The lens 、 The camera 、 Image acquisition module 、 Image processing module 、 Interactive interface, etc  

 6. Machine vision workflow

 7. Case study  

For example, there is an artifact , It is necessary to check whether the size of the three apertures of the workpiece meets the requirements , as follows ：

If a digital camera is used, the above figure can be converted into ：

  If a smart camera is used, the above figure can be transformed into ： The software is directly integrated into the camera
