摘要
为了满足微光条件下的观测成像,设计了一款基于红外、微光融合技术的图像目标侦察系统。该系统在扫描搜索范围内能恒虚警率地定位目标及其相对背景位置,并且自动地跟踪、增强、加亮和染色,然后报警,在进一步增加成像清晰度的同时确保侦察人员对周围保持警觉。本系统基于51单片机和FPGA芯片得以实现,体积小、重量轻、方便安装和使用。通过多次功能仿真以及板上验证,该系统具有较高的执行效率,并且具有良好的侦测能力。
This artical has designed a target detection system to help the observe of objects at the condition of low light level.The system can accurately locate the target and its relative position,automatically find the targets by the constant false alarm rate in the range of scanning,then enhance and dye them to further increase the image clarity,while ensuring the investigators remain vigilant.It was implemented on one FPGA chip,small,light,easy to install and use.Both systematic simulation and onboard verifying indicate that this system has achieved a high efficiency and good detection capability.
