A novel fusion method of SAR and optical sensors to reconstruct 3-D buildings

This paper investigates the method for 3-D buildings reconstruction using the fusion of SAR and optical sensors. First, the joint positioning equation is described as the foundation of this method. Then, the principal steps of this method are recommended. Image registration is employed to obtain a mapping function between the two images as the first step. And the 3-D coordinates are calculated with the joint positioning equation. Afterwards, the 3-D buildings are reconstructed using the 3-D coordinates obtained above. Finally, an experiment is conducted to show the reconstruction result of this method.
