地外天体形貌测绘研究现状与展望

Recent Advances and Prospects in Extraterrestrial Planets Mapping

  • 摘要: 地外天体的形貌测绘产品为深空探测工程任务的顺利实施以及各种行星科学研究提供基础地理信息数据,用于着陆区选址、巡视器路径规划、行星地质与地貌分析等。对月球、火星、小行星探测任务中有代表性的形貌测绘技术与遥感制图成果进行了总结,重点梳理了利用测绘相机、激光高度计等科学仪器获取月球与行星表面的数字正射影像图与数字高程模型的研究现状。结合中国开展地外天体形貌测绘的实际需求,针对标准制定、数据共享、关键技术瓶颈、数据处理技术体系等方面给出了几点建议。

     

    Abstract: The topographic mapping of extraterrestrial planets provide basic geospatial data for engineering missions and various planetary scientific research, which can be used to select landing sites, plan path of rovers and conduct planetary geological and geomorphological analysis. We summarize the representative topographic mapping techniques and products in the exploration missions of moon, Mars and asteroids. This paper focuses on the research status of the techniques of generating digital orthophoto map and digital elevation model using mapping camera and LiDAR. We also give some suggestions on standard setting, data sharing, key technical bottlenecks and data processing technology system of extraterrestrial planets mapping.
