Image processing device and method as well as system

Abstract

The embodiment of the invention provides an image processing device and method as well as system. The image processing device comprises an image acquisition card and a FPGA (Field Programmable Gate Array) processor; the image acquisition card comprises a first interface, an image signal conversion module and a second interface, wherein the first interface is used for receiving image signals output by a high-speed camera, the image signal conversion module is used for converting the image signals into parallel TTL (Transistor-Transistor Logic) signals or CMOS (Complementary Metal Oxide Semiconductor) signals from serial LVDS (Low Voltage Differential Signals), and the second interface is used for transmitting the image signals subjected to the signal conversion to the FPGA processor; and the FPGA processor comprises a third interface and an image signal processing module, wherein the third module is used for receiving the image signals which are transmitted by the second interface and are subjected to the signal conversion, and the image signal processing module is used for carrying out parallel processing on the received image signals. The image processing device solves the problem that the prior art is high in cost as multiple devices are adopted for processing the image signals, and simultaneously the image signals are processed in a hardware manner, thereby the reliability of the image signal processing is ensured.

Description

Technical field [0001] The present invention relates to the technical field of image acquisition and processing, and more specifically, to an image processing device, method and system. Background technique [0002] With the rapid development of machine vision technology, high-speed cameras represented by line scan cameras have been widely used. The signal output interface of high-speed cameras is mostly the standard Camera Link interface, and the signal output rate can reach Gbps (1Gbps is 1204 megabits per second). [0003] For the processing of the Gbps-level image signal output by the high-speed camera, the existing mainstream image signal processing methods are as follows: the image capture card supporting the high-speed camera captures the image signal output by the high-speed camera, and transmits the captured image signal to the host. It can be an industrial computer or a server, and the host performs subsequent image processing according to the preset image processing sof...
