摘　　要：摄影测量模拟实验室可以实现从数据获取到成果输出的全过程摄影测量模拟。为了解决单相机摄影装置只能拍摄沙盘正射影像的缺陷,对摄影装置进行优化设计,使实验室可以同时搭载单相机、五镜头倾斜相机和云台相机3种摄影装置;可以模拟航空摄影测量和倾斜摄影测量,能够拍摄具有不同姿态角的沙盘影像。对沙盘影像进行空中三角测量,精度满足摄影测量规范。将沙盘正射影像空三结果导入JX-4G中进行数字摄影测量,可以得到沙盘模型的"4D"产品;将沙盘倾斜影像导入Smart3D中进行三维模型重建,可以得到沙盘的三维模型。The photogrammetric simulation laboratory can simulate the whole process of photogrammetry from obtaining data to outputting results.In order to solve the problem that a single camera can only take orthoimage of the sand table,by optimizing the photography device,it can carry a single camera,a oblique camera of five lens and a pan-tilt&single camera at the same time.It can simulate aerial photogrammetry and oblique photogrammetry,and take sand table images with different attitude angles.The accuracy of aerial triangulation for sand table images meets the standard of photogrammetry.The"4D"product of sand table can be obtained by importing the aerial triangulation results of sand table orthoimages into JX-4G for digital photogrammetry.By introducing the oblique images into Smart3D for3D model reconstruction,the3D model of sand table can be obtained.
