| Abstract: | An analysis at underwater topographic two-media photogrammetry based on the formula of two-media photogrammetry and seawater as medium from POS data was presented.In this paper,four major steps were involved.First,an introduction of the airborne POS system and the formula of two-media photogrammetry were expressed.In the following step,algorithms for refractive index of sea water and elevation correction coefficient caused that index were discussed.Then,methods for relative and direct orientation of two-media photogrammetry were developed based on the second step.Finally,validation and analysis were processed. |
| Keywords: | POS two-media photogrammetry refractive index of sea water elevation correction coefficient |
