摘要
提出了一种基于DM642处理器和DSP/BIOS操作系统的红外热像仪设计方案。通过PHOTON640红外探测器机芯实现热辐射到电信号的转换,转换后的信号通过FPGA采集并调整时序后直接输出到DSP的采集VP口。DM642对原始数据进行校正、测温等处理后通过网络输出未压缩的高分辨率红外图像,同时通过显示VP口输出红外模拟视频。
A design scheme of thermal infrared camera based on DM642 and DSP/BIOS is presented.Firstly,The conversion of thermal radiation to electrical signal with the utilization of PHOTON 640 is achieved.Then the converted signal is collected through the FPGA and transmitted to VP1 of DM642.Finally,infrared data was processed with nonuniformity correction and send to the host computer to display through the EMAC interface of DM642.
