Abstract
The research has started from the cataloguing of the main low cost photomodeling softwares and technologies that can be found on the Internet. After having selected some programs, the research has been held trying to obtain - using the same set of photos each time - the urban survey of a representative architecture of the island of Procida, which is a little Mediterranean oasis. We have included in our research softwares such as Photoscan, ReMake, ReCap, VisualSFM, and Python.
These programs work starting from an input, which consists in a certain number of photos, to create the output, which is the 3D model of what the photos describe. Having obtained the same model from each program, we will then proceed to analyse each one, in order to find the slightest differences: the main purpose is to understand which low cost programme will give out the best model. The criteria will be mainly based on the colour and dimensional yield that each program will give out.
In conclusion, the main aim of this research is to find the best technologies available, among low cost or licensed programs, which may allow us to get the best survey in the shortest time, in view of further applications in several fields.
