摘要:In the satellite photogrammetry, the base-height ratio greatly impacts the elevation accuracy of the targets for the plotting map, and the greater base-height ratio, the higher elevation precision. The paper firstly analyzes the difference of the projection intersection angles between three linear array satellite and air photogrammetry. Then, the mathematic models calculating the intersection angle and the base-height ratio are detailedly deduced in the three linear array satellite photogrammetry. In order to ensure the elevation precision, the relation of the base-height ratio and the intersection angle is attentively researched in the case of considering the flight altitude. Lastly, the range of the intersection angle of the three linear array CCD camera for the satellite photogrametry is provided to the design system
