Abstract: 
The challenge of reconstructing a polychrome wood statue, which the restorers decides was an intervention for conservation purposes, opened up an artistic/scientific area of work in the field of the restoration of art objects.

This project unfolded in a series of stages in a multidisciplinary context. A process of chromatic restoration and geometric restoration was developed. The work concluded with the development of an interactive 3D representation system with an augmented reality process. 
The work began with the 3D digitalisation of the sculpture through non-intrusive photographic register. This register was treated to map the digitalised geometry and served as the basis for the virtual chromatic restoration with image treatment software. The geometric reconstruction was developed on the basis of the survey of works of art of that time with the same type of symbolic object.

On the 3D surface relating to the destroyed part of the sculpture we tried out a number of solutions whilst fully respecting the survey of works previously carried out. The modelling process is achieved on the drawing projected on the destroyed surface until conclusion of the mask. On conclusion of the work a 3D visualisation in real-time video is implemented.
The modelled mask is superimposed on the computer camera image and positioned according to a location and rotation reference. By calibrating this system it is possible to observe the sculpture with real-time reconstruction.
