摘　　要：本文设计了一种基于多光谱融合图像的飞机姿态测量与导航系统,为飞机自主着陆或着舰提供可靠的导航信息。可见光图像和红外图像融合后的增强图像能够在昼间和夜暗条件下为监控人员、飞行员或者无人机提供可靠的图像信息,同时利用日盲紫外光谱图像具有背景干净和便于目标提取的特点,提高了姿态测量的精度和导航精度。本文对比了融合后的增强图像与单通道图像并分析了融合图像的优点,最后进行了模拟飞行仿真试验并分析了导航系统输出数据的精度。In this paper,an attitude measurement and navigation system based on multi-spectral image fusion is designed to provide reliable navigation information for aircraft landing.The enhanced image after the fusion of visible and infrared images can provide reliable image information for pilots or unmanned aerial vehicles under day and night dark conditions.At the same time,the use of day blind ultraviolet image has the characteristics of simple background and easy target extraction,and attitude measurement accuracy and navigation capability is boosted.Finally,this paper compares the enhanced image and the single channel image,and analyzes the data and accuracy of the navigation system.
