摘　　要：为了深入开展航空光学测绘装备的研制,通过文献调研对该领域主流装备系统的产品性能、系统配置、发展趋势以及关键技术进行研究.研究表明,5 ～6 μm的5～20k大面阵多光谱数字相机是目前测绘相机的主流配置.机载LiDAR（lightdetection and ranging）已发展成为航空测绘装备系统的重要一员,数千米工作高度下的测量精度可达厘米级别,最大测量速度优于250 kHz.为满足更多新兴测绘任务需求,达到优势互补效果,测绘相机与机载LiDAR相结合已成为必然趋势.以30～50 k超大面阵测绘相机为主,机载LiDAR、高光谱成像设备相结合的多传感器测绘平台,是未来的重要发展方向.在高性能多传感器航空光学测绘平台搭建中,存在LiDAR数据效率提升、视场拼接、像移补偿、数据处理等多项关键技术.In order to facilitate the further development of airborne optical mapping equipment, performance, product configuration ,trend and key techniques of mainstream equipment system in this field are studied through literature survey. The study indicates that digitalized large-format multi-spectral camera which is featured with 5 -6 p,m pixel size and 5 - 20 k pixel scale is the mainstream system configuration of airborne mapping camera. Airborne LiDAR （light detection and ranging） has grown into one important member in the airborne mapping equipment products family. The measurement accuracy of airborne LiDAR has reached centimeter level at several kilometers above ground level, and the maximum data acquisition speed is quicker than 250 kHz. In order to satisfy increasing application needs and system function optimization, combination of airborne mapping camera and LiDAR has been the inevitable developing trend. From current perspective, the multi-sensor mapping platform which is composed of 30 - 50 k ultra-large format mapping camera, airborne LiDAR and hyper-spectral sensor is the future trend of airborne mapping equipment system. In the construction of high performance multi-sensor mapping platform, there are several key techniques, such as data acquisition speed improvement of LiDAR, detector alignment, image motion compensation and data processing.
