The vision system of automation equipment looks similar to a camera. Although it looks similar to a camera, it is an integrated micro-machine that integrates image acquisition, processing and communication functions into the vision system, thereby providing a multifunctional, modular, highly reliable and easy-to-implement machine vision solution. At the same time, DSP, FPGA, and large-capacity storage technology are applied. Its function is similar to the coordination between the human brain and eyes, and it can distinguish and identify the position, shape, size, etc. of the product.
1. Composition of the vision system of automation equipment:
The vision system of automation equipment is mainly composed of an image acquisition unit, an image processing unit, image processing software, a network communication device, etc.
1. Image acquisition unit: In the vision system camera, the image acquisition unit is equivalent to a CCD/CMOS camera and an image acquisition card in the ordinary sense. It converts the optical image into an analog (definition: a virtual image of a real thing or process)/digital image and outputs it to the image processing unit.
2. Image processing unit: The image processing unit is similar to an image acquisition and processing card. It can store the image data of the image acquisition unit in real time and perform image processing with the support of image processing software.
3. Image processing software: Image processing software mainly completes image processing functions with the support of the hardware environment of the image processing unit. Such as geometric edge extraction, Blob, grayscale histogram, OCV/OVR, simple positioning and search, etc. In smart cameras, the above algorithms are encapsulated into fixed modules, and users can directly apply them without programming.
4. Network communication device: The network communication device is an important part of the visual system camera, which mainly completes the communication tasks of control information and image data. Smart cameras generally have built-in Ethernet communication devices and support a variety of standard networks and bus protocols, so that multiple smart cameras can form a larger machine vision system.
2. The role of the vision system of automation equipment:
Automation equipment is the main force of vision system applications, especially in some non-standard automation equipment with complex feeding systems.
3. Benefits of the vision system of automation equipment:
The vision system of automation equipment can accurately identify some relatively precise and vulnerable parts, or some materials that have been surface-treated and some materials with special shapes, without causing damage or scratches to the objects.
Visual cameras are widely used in product inspection in manufacturing companies due to their compact structure, simple operation, high stability, and low cost. They are embedded with high-performance processors and flexible communication device interfaces. You only need to connect the camera to the host and install the corresponding software to inspect the products on the production line, saving a lot of installation and debugging time.
