摘　　要：航空摄影测量伴随着航摄仪的快速迭代进化而不断向前发展。基于常州全市域航空摄影和正射影像图制作项目,采用AIMS航空集成多传感器航摄仪,同步获取下视影像、倾斜影像、激光点云和高光谱数据,综合运用TerraSolid和自主研发的P3C软件对点云进行分类处理,获取地表点生成DEM,对下视影像进行空三解算,利用DEM对影像进行数据微分纠正获得正射影像图。项目通过多源数据同步获取、融合处理,提高了传统3D产品的生产效率。Aerial photogrammetry continues to move forward with the rapid iterative evolution of aerial cameras.This paper based on the Changzhou aerial photography and orthophoto map production project,AIMS integrated multi-sensor aerial camera was used to simultaneously acquire down-view image,oblique image,laser point cloud and hyperspectral data,and comprehensively used TerraSolid and self-developed P3C software to analyze the point cloud,perform classification processing,obtain surface points to generate DEM,perform spatial triangulation on the down-view image,and use DEM to perform data differential correction on the image to obtain an orthophoto image.The project improves the production efficiency of traditional 3D products through the simultaneous acquisition and fusion of multi-source data.
