| 中文摘要:本文针对恐龙骨骼化石保护中化石风化状态难以监测的问题, 采用地面三维激光扫描(TLS)方法获取化石表面的精细三维点云数据, 通过间隔7个月前后两期三维数据对比, 分析化石表面因风化作用产生的变化。选取山东诸城恐龙化石产地2处恐龙骨骼化石进行了两期数据采集并对化石表面整体及其裂缝进行分析, 发现在监测周期内, 监测对象整体无明显变化, 局部存在斑状变化(偏差达0.7 mm), 主要裂缝区域变化小于0.2 mm。实验结果表明本文采取的监测方法可以监测化石亚毫米级变化, 对同类化石风化监测提供了参考。 |

| Abstract: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. |
