Photogrammetry is the science that constantly mutates and adapts to technological developments in the field of imprinting objects. It represents today, globally, the main production methodology of cartographic backgrounds. The progress that has occurred in recent years in the development of this technology, particularly in the field of analytical and digital photogrammetry, combined with those of aerial photography, have created conditions for production of extremely high-precision topographic backgrounds and many more. In this thesis we dealt with the three-dimensional imaging of a model, a field of digital photogrammetry. Τhe three-dimensional imaging refers to the realistic representation of three-dimensional objects and surfaces. This is necessary for several reasons. One of the reasons is that the observer can observe the model from different angles and see an object or a three-dimensional region. This is associated with the natural ability to see three-dimensional resulting in better understanding of the complexity of surfaces and their geometry. The aim of this thesis is the three-dimensional imaging of three models and the mapping of a human face, using entirely free software applications both for interior orientation of the camera we using and for processing and final display of the model. For the shooting of the models we used a compatible digital camera, Nikon D90. For the interior orientation of the camera we used Fauccal, a free toolbox for Matlab. For the three-dimensional representation of the model we used the free photogrammetric station, 123D catch. These stations, with simple methodologies and procedures, can solve various photogrammetric problems and produce reliable and accurate models.
