基于FPGA的CMOS图像传感器采集系统设计

Design of the CMOS Sensor Image Acquisition System Based on FPGA

针对大市场、小目标实时监测系统测量视场与测量速度相互制约的问题,研究了基于FPGA的具有CMOS ROI控制功能的图像采集系统的设计。应用FPGA驱动CMOS IBIS-6600,并对其获取图像进行实时预处理,提取小目标位置信息,进行图像开窗跟踪,实现对高速运动的小目标实时精确定位。开窗跟踪技术,缓解了监测系统中测量视场与测量速度间的矛盾。

For the wide field and small target real time monitoring system, research the design of the CMOS sensor image acquisition system based on FPGA, FPGA has been applied to drive the CMOS IBIS--6600, as well as to preprocess the image it gets, distill the position information of small targets, and then drive the CMOS under the ROI read out mode to track the high speed moving target. The application of the ROI read out technique relieves the contradiction between the field and speed in the monitoring system.
