First Steps Toward Spatio-Temporal Rheims Reconstruction Using Old Postcards

We address the problem of the 3D reconstruction of Rheims (France) using sparse data. We consider an old postcard dataset embodying the period from the beginning to the middle of the 20th century. Our reconstruction have to take into account spatial and temporal aspects that are implicitly characterizing our dataset. Indeed Rheims was destroyed during the first World War, we dispose of postcards taken before, during and after the war. The first steps of our work consists in determining the best way to match different views of the same place. This study reports on performance comparison of state-of-the-art couple of detectors-descriptors that are most robust and reliable in the context of our application.
