EVOC IPC design machine vision method

Machine vision is a skill that uses computer and various sensor skills to complete the understanding and processing of drawings, videos, or other visual data. It is mainly composed of industrial cameras, light sources, industrial computers and corresponding picture analysis software systems.

Machine vision is used in the manufacturing industry, mainly for appearance inspection, defect detection, etc., the detection requirements are different, but the detection process is through CCD and collection card to obtain pictures, and through the industrial computer for analysis and processing. In this process, the target can be automatically photographed, recorded, stored, and transmitted.

The operating principle of machine vision is like a single-function industrial robot, such as using a camera to obtain a picture of the detected policy, and the special light source makes the characteristics of the detected policy be strengthened in the picture, such as scale features, surface defect characteristics, etc. The picture with clear characteristics is transmitted to the industrial computer at high speed, and the characteristics are analyzed and processed to calculate the features, and the industrial computer can control the actuator to classify, reject, alarm and other actions according to the accounting results. The advantages of machine vision are:

Continuity: The industrial computer can operate 7*24 hours uninterruptedly, which is stable and reliable, and ensures that there is no omission in product testing.

High accuracy: the detection accuracy can reach one thousandth of an inch.

Flexibility: It can complete the fast and accurate identification and tracking of objects, faces, barcodes, QR codes and other policies, can detect the size, shape, shortcomings, stains and other problems of products, and can also carry out intelligent analysis and resolution planning.

In the machine vision system, the industrial computer converts the ingestion policy into a picture signal, transmits it to a special picture processing system, obtains the shape information of the captured policy, and then completes the detection operation, during which the picture processing is completed by the industrial computer. It can be seen that in machine vision, the function of the industrial computer directly affects the processing speed and operation time of the entire vision system, and is the key point of the entire vision system. How to design an industrial computer for machine vision?

1. Equipment of industrial computer

The industrial computer selects high-performance equipment to complete the efficient, accurate and real-time picture collection, processing, analysis and identification, and supports real-time monitoring and control to meet the needs of industrial use that require rapid response. For example, in order to speed up the processing speed, the current transformer is reduced, and the solid-state drive is used instead of the mechanical hard drive.

2. The interface and expansion slot of the industrial computer

The industrial computer supports a variety of picture input and output interfaces, such as USB, GigE Vision, Camera Link, HDMI, etc., and can be connected with various industrial cameras, sensors, displays and other devices to complete a variety of picture input and output. Furthermore. Some machine vision algorithms rely on robust functional accelerators, such as GPUs, for real-time accounting parallelism. The IPC is required to have a PCIex16 slot and the bandwidth meets the needs of GPU use.

3. Customization of industrial computer

Industrial computer manufacturers can customize design and manufacture according to the needs of use to meet the needs of different customers and occupations.
