An image acquisition system and image data processing method

Abstract

The invention provides an image acquisition system and an image data processing method, and relates to the technical field of image signal. The system comprises an image acquisition module, an image processing module and a network transmission module. The image acquisition module converts the received LVDS (Low Voltage Differential Signaling) signals into digital signals capable of being processedby the image processing module, so that the image processing module reads the LVDS signals from the image acquisition module, compresses the read LVDS signals and transmits the compressed LVDS signals to the network transmission module; and the network transmission module transmits the compressed LVDS signals to peripheral equipment. The technical problems of the short transmission distance and the slow transmission speed of the LVDS signals and the slow response of the image are solved.

Description

technical field [0001] The invention belongs to the technical field of image signals, and in particular relates to an image acquisition system and an image data processing method. Background technique [0002] The LVDS interface is a low-voltage differential signal technology interface, which uses low voltage for differential signal transmission, and the differential signal voltage swing is only about 350mV. Using this interface can make the signal transmission rate on the differential line reach several hundred Mbps, and because of the low-voltage and low-current drive mode, it can greatly reduce signal noise and power consumption. At present, for the acquisition of LVDS signals, there are mainly acquisition cards and LVDS conversion modules, and the implementation methods include FPGA+DSP, FPGA+PCI bus, FPGA+USB transmission interface, etc. The main function is mostly to convert LVDS signals to VGA, HDMI and other signals, and display them locally.

Problems solved by technology

[0003] When studying this application, the researchers found that the current LVDS signal acquisition has the following disadvantages: LVDS signal transmission distance is short, too long communication lines will increase the loss of the transmission process, reduce the transmission rate, and affect the integrity of the signal; the video acquisition card High cost, complex technology, single function, and need to design an independent software driver, the application range is small, and it is not easy to expand other functions
