Abstract. The painted surfaces of a building are generally vertical walls and flat roofs or arched roofs. The detection of these objects must be prepared according to the reason why the metric operation is designed; metric control of the whole performance practice is crucial for the result to matches the predetermined needs.
It's now clear that the acquisition of metric data, as the whole process of detection, can certainly not be left to an unidentified automation.
The mere representation of point clouds transformed in mesh and processed into 'maps' can cover only a few limited requirements. Conservation and restoration also require the transformation of "discrete" three-dimensional data into two-dimensional representations, resulting in geometric transformations that require a new mindset, especially considering hardware and software potential.
We want to propose a new type of projection end analysis as base for the development of representation systems that will transform three-dimensional models in two-dimensional projections for the conservation and restoration.
