Abstract

The aim of this paper is to propose a framework for the use of both SAR and optical data in a 3D reconstruction process. The SAR data provide height information either by interferometric or radargrammetric process and the optical data provides building shapes. The method is based on a Markov random field defined on a Region Adjacency Graph. The regions are obtained using a segmentation of the optical image. The graph is then fed by the height information (either interferometric or radargrammetric) computed with the SAR data. The Markovian regularization takes height discontinuities into account thanks to an implicit edge process.
