“…From this point of view, videogrammetry is shown as a technique capable of combining the advantages of laser scanner and photographic image [13,14]. Methodologies based on video techniques are more often found in several fields such as robotics [15], erosion [16] and studies of fluid processes [17,18] among others. The capture of hundreds of images in a video sequence allows measurement of thousands of points by automatic processes to obtain a 3D model [19].…”

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 accuracy.
