Embedded parallel multi-channel digital image acquisition system based on GigE interface

Abstract

The invention discloses an embedded parallel multi-channel digital image acquisition system based on a GigE interface. The embedded parallel multi-channel digital image acquisition system comprises an industrial local area gigabit Ethernet, a camera based on a GigE interface, an industrial computer, and a digital image acquisition embedded device based on a GigE interface. The digital image acquisition embedded device based on a GigE interface is the core device of the system. According to the invention, embedded image multi-channel simultaneous acquisition based on a GigE interface can be realized, and advantages, such as high transmission rate, low image transmission distortion rate, convenient networking, convenient installation, convenient maintenance, etc., can be realized. The digital image acquisition embedded device based on a GigE interface is designed for specially acquiring GigE camera image data in a local area network. Embedded systems developed based on the invention can be widely applied in industrial production field monitoring based on machine vision.

Description

technical field [0001] The invention relates to a digital image acquisition system, in particular to an embedded parallel multi-channel digital image acquisition system based on a GigE interface, belonging to a digital image processing system. Background technique [0002] As a common means of framing, machine vision has been widely used in many fields. The image acquisition device is the data source in the entire image processing system and is an essential part. [0003] At present, most of the image acquisition and processing devices used for monitoring and control are based on PC and image acquisition cards. In this mode, the image acquisition card collects images from industrial cameras, and the PC processes the images and obtains the results. According to the processing results, the PC can control and operate related equipment through other interface equipment. If you want to perform multi-channel image detection, you need to expand the image acquisition card on the ...

AI Technical Summary

Problems solved by technology

[0004] Since the PC operates serially on instructions and data, the image can only be processed one by one, resulting in a decrease in image processing speed, which becomes the bottleneck of the entire system acquisition, which in turn affects the real-time performance of subsequent data operations

In addition, with the increase in the number of image acquisition and processing channels, the bottleneck of the processing power of the PC should become more prominent.

[0005] Furthermore, the purchase cost of the hardware equipment of the PC and the copyright fee of the corresponding operating system and high-level language development software will greatly increase the user cost.

Especially when the PC and acquisition card structure is installed, multiple data lines will be used to connect to the computer at the same time, which will lead to a series of problems such as difficult on-site wiring, high cost, and cluttered lines.
