| description | In this paper we present a radiometric block adjustment method that is related to geometric block adjustment and to the concept of a
terrain Digital Radiometric Model (DRM) as a complement to the terrain digital elevation and surface models. A DRM, in our concept,
is a function that for each ground point returns a reflectance value and a Bidirectional Reflectance Distribution Function (BRDF).
In a similar way to the terrain geometric reconstruction procedure, given an image block of some terrain area, we split the DRM
generation in two phases: radiometric block adjustment and DRM generation. In the paper we concentrate on the radiometric block
adjustment step, but we also describe a preliminary DRM generator. In the block adjustment step, after a radiometric pre-calibraton
step, local atmosphere radiative transfer parameters, and ground reflectances and BRDFs at the radiometric tie points are estimated.
This radiometric block adjustment is based on atmospheric radiative transfer (ART) models, pre-selected BRDF models and radiometric
ground control points. The proposed concept is implemented and applied in an experimental campaign, and the obtained results are
presented. The DRM and orthophoto mosaics are generated showing no radiometric differences at the seam lines. |
