Why photogrammetry?
What makes the difference, between photogrammetry and other survey techniques, is artificial stereo vision, which differs from natural stereo vision because it provides us, "within reach", the virtual scale model of the object to be detect, meeting our natural needs for optimal observation. Other advantages of photogrammetry are: - rapidity of the survey, which, in the case of shooting, both with a single camera and with the stereometric camera, is reduced to the shooting time of a couple of photographs; - remote surveys, ie the possibility of detecting an object, in all its details, without the need to "touch" it. Think of the case of natural disasters or. however, with particularly dangerous findings; - restitution after some time, that is, the possibility of detecting the measurements that are needed, with peace of mind in the laboratory, even after years from the survey and, with the use of the Internet, far from the documentation center; - establishment of international archives, according to the indications of the CIPA. With online archives, a link is sufficient to connect to the archive or to the simple survey; - verify the restoration project directly on the virtual model, thanks to the reverse photogrammetry;
