Image processing device for image data

Abstract

The invention provides an image processing device for image data, which comprises a CCD camera, a programmable gate array, a digital signal processor, a data assembly module and a display module, wherein the programmable gate array is connected with the CCD camera; the input end of the digital signal processor is connected with the output end of the programmable gate array; the data assembly module is connected with a gigabit network sending module of the digital signal processor; and the display module is connected with the data assembly module. Through software setting, the device can acquire the data of CCD cameras with a Camera link interface, different frame frequencies and different resolutions at a high speed in real time, and transmits and displays the acquired data in real time to facilitate field diagnosis and debugging; meanwhile, the device also has the advantages of miniaturization, real-time, high bandwidth and simple upgrade.

Description

technical field [0001] The present invention relates to image processing and image acquisition, the field of image communication, in particular to the high-speed real-time acquisition of image data of Camera link interface type based on programmable logic gate array FPGA and digital signal processor DSP, based on external memory interface EMIF and gigabit High-speed real-time transmission and display device of network transceiver module Ethernet MAC. Background technique [0002] In traditional image processing, image acquisition is often the first link. The general acquisition device is an image acquisition card used in conjunction with a personal computer. The acquisition card is inserted into the PCI slot of the personal computer, and the collected image data Store it on the hard disk of the personal computer, and then analyze and process the collected images, including image enhancement, image compression, image communication and other processing methods. Such an acquis...

Problems solved by technology

Such an acquisition device has the following disadvantages: the space is large and cannot adapt to the development trend of miniaturization of electronic equipment; it is not real-time, and the collected images must be transferred to the hard disk first, and the data is generally read from the hard disk afterwards. Analyzing the data is not conducive to on-site analysis and debugging; the bandwidth is limited, the PCI slot of a general computer is only 32 bits wide, and the frequency is only 33MHz. Calculated at 80% utilization rate, the bandwidth is only about 100MB / s, which is not enough. Real-time acquisition of high frame rate and high-resolution image data; equipment upgrades are cumbersome. If you want to upgrade image acquisition and transmission display equipment, you need to replace the acquisition card and computer at the same time, which is time-consuming and laborious, and the cost performance is not high
