基于红外与微光融合图像的夜视仪设计

摘要

This paper designed a night vision system based on infrared and low light level imaging to aware the status of around environment at any time in the dark of night. The vision can accurately locate the target and its relative position, automatically find the targets with the constant false alarm rate in the range of scanning, enhance and dye them to further increase the image clarity, and then automatically transfer the acquired information to command center and neighbor via digital signal, while ensuring the investigators well familiar with surroundings and keep in touch with others at the same time. Both systematic simulation and onboard verification indicate that this system has achieved a high efficiency and good detection capability.%在漆黑的夜幕下，为了能随时掌握周围环境动态，设计了一款基于红外、微光融合技术的夜视仪系统。该夜视仪能够准确定位目标及其相对背景位置，自动地增强和染色目标，并且在扫描搜索范围内恒虚警率地发现跟踪目标，然后将获取的目标信息以数字信号的方式自动传输给指挥中心和友邻，使侦查人员对周围环境更加熟悉的同时保持同各方保持联系。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。
