基于FPGA的实时视频采集预处理系统设计
Design of Real-time Video Capture and Pretreatment System Based on FPGA
摘要
采用Verilog语言设计了一套基于RGB格式的视频采集预处理系统,先将采集到的RGB信号转换成易于处理的YCbCr信号,然后进行相应的处理,最后再转为RGB信号输出显示.系统包含视频采集模块、视频显示模块、IIC控制模块和视频处理模块.各个模块的功能通过在Xilinx公司的XC5VLX110T上得到实现.给出了系统的效果演示、仿真结果和效率分析,结果表明该方案是可行的,并且在处理速度上有很大的优势.
Abstract
A video capture and pre-treatment system for RGB was designed by Verilog HDL.First,the collected RGB signal was converted into YCbCr signal.Then,it was processed and converted into RGB signal to be displayed on the screen.The system includes video input and output modules,IIC control module and preprocessing module.And the demands of each modules in the system were realized on XC5VLX110T of Xilinx company.The test and simulation results indicate that the system is feasible and has great advantages in processing speed.
