3D Modelling of Petrified Trees: Laser Scanning vs Photogrammetry

摘要

In this paper, a methodology for the photogrammetric and laser scan survey of tree fossils of the Petrified Forest on Lesvos island in Greece, is proposed. The Petrified Forest is of particular interest since it is one of the rarest monuments of geological heritage worldwide and it was formed from the fossilized remains of plants. During this study, photogrammetric and laser scanning data by the tree fossils have been gathered, processed and modelled in 3D, and a comparison of the two techniques is taking place. Finally, the most suitable technique for the 3D modelling of objects such as the petrified trees is proposed.
