Abstract


With the development of the field of machine vision , real-time image processing urgent needs , the software implementation of image processing can not meet the real-time demand , directly based on specific integrated chip implementation of the development cycle is too long, too difficult to develop . The rapid development of FPGA ( field-programmable gate array ) changed the status quo , so that the hardware implementation of real-time image processing becomes feasible . FPGA-based image processing has become a hot area of the home and abroad now . FPGA development platform using VHDL ( ultra- high-speed hardware description language ) FPGA-based image acquisition and processing system . The system includes image acquisition module , image processing module , debugging module , display module four parts , image acquisition module based on the real-time images of the Camera Link standard CCD line camera acquisition ; image processing part of the basic image processing algorithms include the gray histogram statistics, image convolution filter and image median filtering , and in-depth study of the image convolution algorithm and optimization of the algorithm to adapt the structure of the FPGA ; debugging the acquisition and processing of data transmitted to PC via UART interface with software data processing results contrast ; show the results of the real - time image processing module of the completion . The entire design the ISES9.2 and the Modelsim simulation software environment developed in the Xilinx Spartan-3 XC3S200 hardware platform . Use of software simulation process use ISE 9.2 comes with simulation tools and Modelsim . Finally, build a platform of image acquisition and processing system , good real-time image acquisition and processing .
