| A Study of the Weathering Monitoring of Dinosaur Bone Fossils Based on TLS |
| This paper aims at tackling the problem that it is difficult to monitor the weathering state of fossils in the protection of dinosaur bone fossils. Through obtaining fine 3D point cloud data of fossil surface by terrestrial laser scanning and on the basis of the comparison of three-dimensional data of two periods at an interval of 7 months, the change of the fossil surface caused by weathering was analyzed. Two dinosaur bone fossils from Zhucheng area of Shandong Province were collected for two periods of data collection, and the whole surface of the fossils and their fractures were analyzed. It is found that, during the monitoring period, there was no obvious change in the monitoring object as a whole, and there was spot change (deviation of 0.7 mm) in some parts, with the change in the main fracture area being less than 0.2 mm. The experimental results show that the monitoring method adopted in this paper can monitor the submillimeter scale changes of fossils and provide a reference for the weathering monitoring of similar fossils. |
