Abstract: A survey and 3D modeling were performed to obtain a three-dimensional model of a complex-surface object using photogrammetry. The object was photographed from different angles, si 264 photos were obtained overlapping 90%. To get the model in real size, scale bars were placed next to the statue, which serve as the basis for scaling the model during processing. Using the Agisoft Photoscan software package, photos were processed and an accurate three-dimensional model of the object was created with an accuracy of 1,5 mm.

Keywords: photography, scanning, modeling, dot cloud, stereo image.
