大面阵高清高帧CMOS枪瞄系统关键技术

摘要

为了使射手能快速观察并瞄准战场目标,设计并实现了一种基于大面阵高清高帧频CMOS图像传感器的数字枪瞄系统;重点解决了系统中的几个关键技术:硬件电路设计、基于FPGA的CMOS驱动、图像格式转换和瞄准分划的动态生成与位置调整;实验结果表明:该系统可在采集分辨率为2 560×2 048,显示分辨率为1 280×1 024,帧速为75 fps,数据传输速率为2G bps方式下稳定地工作.%In order to enable the shooter to observe and target the battlefield,the paper designed and realized a digital riflescope system based on high definition and huge frame and large area array CMOS.In this paper,the key technologies for realizing the system were solved.It includes hardware circuit design,CMOS driver based on FPGA,image format conversion and dynamic generation and position adjustment of targeting differentiation line.The experiment results indicate that the system can stably work at the resolution of 2 560 × 2 048,the display resolution of 1 280 × 1 024,the frame rate of 75 fps and the data transmission rate of 2G bps.
