These data allow metric modeling if the object’s polyhedral nature is exploited. Thus, 3D reconstruction was based on transferring X, 
Y or Z point coordinates through intersecting planes, assuming their orthogonality or parallelism. The model was completed with all 
required additional details, e.g. the balcony lattices. For texturing the model other images were also used, while artificial texture was 
added wherever needed (texturing and animation was performed in 3DStudio Max). Frames of the textured model are seen in Fig. 5.

4. THE PANORAMIC IMAGE 
As already mentioned, panoramic images can be generated either with specially designed rotating cameras or simply through mutual 
rectification of images taken from the same standpoint. If full view (360°) panoramic images or images with very large angular 
openings (for instance > 150°) are required, then a cylindrical projection is needed. For smaller angles, projection on a plane suffices.
