These reconstructions are obtained from one or more images in which some 2D points are identified by hand and some apriori geometric information, such a known planarities, angles, symmetries and other forms of regularity. From this information, the leastsquares reconstructions are computed, together with estimates of the precision with which they are obtained.
A brief summary of each dataset is given. The maximum likelihood reconstruction assuming the errors in the 2D observations are Gaussian is given in the form of a VRML model. The images come mostly from scanned postcards.
Full description of how the reconstruction is obtained can be found in my PhD thesis [4], (123 pages, ~2MB), our 2005 article [5] in Computer Graphics and Image Understanding ,or from two smaller articles that discuss geometric aspects [1], (449KB) and probabilistic aspects [3] (600KB).
