【Abstract】 Correct approaches to identification of dark objects and appropriate choice of atmospheric correction models are key technologies in Dark-Object Methods. On such a basis, researchers have put forward several different improved Dark-Object Methods. The basic idea of Dark-Object Methods and different atmospheric correction models are described in this paper. Two of these models are chosen to correct the atmospheric effects on the scene of SPOT satellite image. It is also pointed out that the methods need further improvement and that we should comprehensively consider their defects in practice.更多还原
