Close - Range Photogrammetric Digital Projector Approach (DigPro)

A new approach has been established for digital restitution and orthomapping of close range objects of almost any shape and size and with almost no restriction to images or objects. The idea of this approach is an inversion of the photographic technique and is (on the contrary to the "rectification approach") strictly object oriented. All of the objects are regarded to be describable in their geometrical shape by a number of particular faces that can be regular or irregular but can anyway be created in a CAD environment. The data needed to get this surface can come from any photogrammetric, tachometric or other source with any particular one wants to have for the results. All the details that lie on that surface don't have to be restituted by analog or analytical point measurement but can after that be projected onto this surface from any photo, from any side and with any camera they have been taken. A "Digital Projector" does the projection of the photos from the same positions and with the same inner orientation as of photographic camera. Using this approach, any measurements of any details on the facades can be done easily. No details of the object can be neglected.
