Title Based on the FPGA low illumination CMOS image processing and detection technology research
Abstract
It is constantly increasing of image processing and detecting technology with the development of the time. The night moving targets detection based on FPGA technology is an important part of this technology and become research hot spot.And the moving target detection technology has been widely used in military, traffic, security monitoring,etc.Therefore, research on moving target detection invested a lot of manpower and material resources at home and abroad.This topic has designed a kind of low illumination CMOS motion target detection system based on FPGA.
First ,this article expounds the moving target detection and low illumination CMOS research significance and research status.Second then this topic by using the software and hardware platform is introduced, mainly including low illumination CMOS camera, the FPGA development board, display, power supply, etc.It achieves the goal of frame differential method detection method on the basis of the existing motion target detection.Finally, through the analysis of the moving object, and using verilog programming, realizing the collection of the signal, processing and output.the video acquisition based on FPGA, display and the goal of sports into the alarm function.
