Assignment of colour in three dimensional models

Nowadays, current three-dimensional sensors provide geometric information with a high degree of accuracy. The colorimetric information is provided through a color camera which can be inserted or not into the 3D sensor, so that the whole information (points + color) is available for each scan of the scene. However, the integration of color information from different scanner positions is an issue which has not been satisfactorily solved in the current digitalization systems. This work focuses on developing techniques which obtain a complete 3D digitalization (geometry + color) from different scans of the scene, paying particular attention to the texture merging.
