| 简仪是元代天文学家郭守敬于公元1276年创制的一种测量天体位置的天文仪器,堪称中国古代传统天文学成就的杰作与象征。现存简仪是郭守敬简仪的仿制件,成于明英宗正统年间,目前陈列于紫金山天文台。为尽可能地留存此重要文物的空间结构与器身形貌信息,有必要对其实施原位、无损、高精度的测量研究。本文主要介绍了基于三维激光扫描技术的简仪空间结构与器身形貌测量建模研究成果。 |

| Abstract: |
| Abridged Armilla is an astronomical instrument for measuring the position of celestial bodies created in 1276 AD by Guo Shoujing, an astronomer who lived during the Yuan Dynasty. It is regarded as the masterpiece and symbol of the achievement of ancient Chinese traditional astronomy. The existing Abridged Armilla is a replica of Guo Shoujing's. It was made during the Zhengtong period of Emperor Yingzong in Ming Dynasty and is currently on display at the Purple Mountain Observatory. In order to retain the spatial structure and shape information of this important cultural relic as much as possible, it is necessary to carry out an-situ, non-destructive and high-precision measurement research. This paper mainly introduces the research results from the measurements and modelling of spatial structure and body morphology of Abridged Armilla based on 3D laser scanning technology. |
