CHEAP PHOTOGRAMMETRY VERSUS EXPENSIVE REVERSE ENGINEERING TECHINQUES IN 3D MODEL ACQUISITION AND SHAPE RECONSTRUCTION
The aim of the paper is to verify a procedure both for acquisition and reconstruction of 3D CAD Models combining photogrammetry and R.E. techniques. This procedure utilizes some photogrammetry-based software. 3D points cloud obtained using photogrammetry software has been compared with CAD model by means of some mathematical tools.The several tests made on different objects confirm the usability of this approach to many real cases where the high accuracy is not mandatary and a fast and cheap solution is required.
