Design of real-time image acquisition and display system based on FPGA

Abstract

With the development of recent years, video image acquisition technology is also in constant progress and development. The technology can be widely used in all walks of life. With the promotion and development of technology, image technology for real-time and image computing requirements are constantly improving. Image storage needs logic resources also increased significantly. Aiming at this problem, it needs to develop a kind of applicable image acquisition and display system on the hardware. In order to reduce the use of logic resources and add some image processing algorithms on the system platform, this paper usesNEXYS4DDR series FPGA of Xilinx company to realize the system. The front-end image acquisition uses CMOS image sensor OV7670. The cache adopts the IP core SRAM integrated with Xilinx vivado platform. The system displays the real-time video image data through VGA display, and uses hardware description language Verilog HDL. Through simulation test, the system can fully realize the function of real-time image acquisition and display.
