The imaging model for aerial long range oblique photography(LOROP) camera is the basis of geometric calibration, atmospheric refraction and assemble error correction. Through analysis of the imaging principle for LOROP camera, eliminating the moving photography center, the strict imaging model for LOROP with physical meaning and solvability is constructed, and its correctness is verified by simulation, which provides a reference for the related research. The oretical analysis and simulation measurements show that the system whose optical system and scanning mirror sweep together has the advantage of no image-rotation. The control situation of LOROP camera is analyzed theoretically. Results show that the cross-track scanning position and image motion compensation speed are nonlinear process which is positive correlated with the aviation speed and height.
