摘要/Abstract

摘要： 航空长焦距斜视相机成像模型是几何检校、大气折射和安置误差改正的基础。本文在分析长焦距斜视相机成像原理的基础上，剥离运动的摄影中心，构建了其具有物理意义可解的严格成像模型，通过仿真验证其正确性，奠定相关研究的基础。此外，通过理论分析和模拟量测，得出光学系统与扫描镜以前摆扫的系统具有无像旋的优点。最后，从理论上分析了长焦斜视相机的控制情况，穿轨扫描位置和像移补偿为与航速、航高正相关的非线性过程。

Abstract: The imaging model for Aerial LOng Range Oblique Photography (LOROP) camera is the basis of geometric calibration, atmospheric refraction and assemble error correction. Based on the analysising of the LOROP camera imaging principle, eliminating the moving photography center, we construct a strict imaging model of LOROP camera, which through simulation verify its correctness, making the model solvable and has physical meaning, lays the foundation of related research. In addition, through theoretical analysis and simulation measurements, we can conclude that the LOROP camera has the advantage of no image rotation. Finally, theoretical analysis of the motion control of the LOROP camera indicates that the scanning position and the speed of image motion compensation were nonlinear processes.

Key words: LOROP
