Design and calibration of a 3D modeling system by videogrammetry

Nowadays, close-range photogrammetry and a laser scanner are the two most popular techniques in reconstruction of three-dimensional objects. This paper develops a methodology based on videogrammetry to reconstruct 3D objects more quickly than conventional photogrammetric techniques and more cheaply than a laser scanner. Videogrammetry allows the capture of thousands of points in a very short space of time (like a laser scanner) and the object s geometry and texture (frames are photographic images as stereo pairs). A system composed of a video camera and a turntable support with a double platform over it has been developed. This paper shows the design, construction and calibration of the system to model 3D objects contained on the support with pinpoint accuracyHerráez Boquera, J.; Martínez Llario, JC.; Coll Aliaga, E.; Rodríguez, J.; Martín, M.
