Collected Shape Models of Comet 67P/Churyumov-Gerasimenko Produced by the Rosetta Mission

This dataset contains a variety of shape models for comet 67P/Churyumov-Gerasimenko, the target of the Rosetta mission, together with a definition of the body-centered coordinate system for the nucleus. Models were developed by the OSIRIS instrument science team using stereophotoclinometry; by the European Space Agency (ESA) Rosetta Mission Operations Center (RMOC), by applying stereophotoclinometry to NAVCAM images; and the German Aerospace Center (DLR), by applying stereo-photogrammetric techniques to the OSIRIS images. The shapes are presented as triangular plate models in various forms, include a digitel kernel shape (DSK) format for use with the NAIF SPICE toolkit, and .obj files suitable for 3D printing. Each model is presented in multiple resolutions and multiple formats. Documentation is included.

本数据集包含多款用于罗塞塔（Rosetta）任务目标彗星67P/楚留莫夫-格拉希门克（67P/Churyumov-Gerasimenko）的形状模型，同时附带彗核的体心坐标系定义。该数据集的模型由三方团队分别开发：其一为OSIRIS仪器科学团队，通过立体光测术（stereophotoclinometry）完成建模；其二为欧洲空间局（ESA）罗塞塔任务运行中心（RMOC），将立体光测术应用于NAVCAM图像以构建模型；其三为德国航空航天中心（DLR），通过对OSIRIS图像运用立体摄影测量技术实现建模。这些形状以三角面片模型的形式提供，涵盖多种格式，其中包括适配NAIF SPICE工具包的数字核形状（Digital Kernel Shape, DSK）格式，以及可用于3D打印的.obj格式文件。所有模型均提供多种分辨率与多种格式版本，并附带完整文档资料。
