In this work we present a comparison between two different techniques to generate a DEM of a sample mould. In the first part an automatic extraction of object’s DEM from orthophotos is performed using the digital photogrammetric software OrthoEngine by PCI, while in the second part the mould is scanned by a laser range camera (BIRIS), by which the range data are directly acquired in a computer readable form. Then, the resulting DEMs are compared through Surfer software in order to evaluate the accuracy achievable from these techniques in 3D object model reconstruction.

Abstract
In this work we present a comparison between two different techniques to generate a DEM of a sample mould. In the first part an automatic extraction of object’s DEM from orthophotos is performed using the digital photogrammetric software OrthoEngine by PCI, while in the second part the mould is scanned by a laser range camera (BIRIS), by which the range data are directly acquired in a computer readable form. Then, the resulting DEMs are compared through Surfer software in order to evaluate the accuracy achievable from these techniques in 3D object model reconstruction.File in questo prodotto:
