Filling lacunas in terrestrial laser scanning data : the Cavallo ligneo of the Palazzo della Ragione (Padua, Italy)

Laser scanning methodology allows to reconstruct the metric characteristics of objects at different LOD (Level Of Detail) providing spatially dense points clouds. In particular, the terrestrial application carried out in the last years have demonstrated the potentialities of the methodology useful in many different sectors. This tecnique has been used also for the “Cavallo ligneo” of the “Palazzo della Ragione” (Padua, Italy) survey providing useful data for the restoration of the wooden horse. Due to the morphologic complexity of the object, some lacunas were created during the points clouds acquisitions: different procedures to filling lacunas were considered and applied providing a complete 3D model of the wooden statue
