从地球测绘到地外天体测绘

From Earth mapping to extraterrestrial planet mapping

随着人类空间探测技术的不断发展,月球与深空探测已成为测绘遥感科学与技术的前沿和新战场。在多类型深空探测任务的驱动下,测绘遥感技术也得到了新的发展。本文结合国内外深空探测的各类任务,对地外天体环绕遥感测图、着陆导航遥感避障、巡视环境感知与视觉导航定位方面的研究现状和成果进行了系统总结;结合未来月球与深空探测任务需求,对深空遥感测绘技术的发展,包括地外天体海量全球遥感数据智能处理、全球控制网精化、月球南极精细三维形貌测绘、多传感器融合的着陆导航避障和巡视环境感知与定位等进行了探讨。

With the continuous development of human space exploration technology,lunar and deep space exploration has become a new battlefield and frontier of surveying and remote sensing science and technology.Driven by many types of deep space exploration tasks,surveying and mapping remote sensing technology has been developed.With various tasks of deep space exploration,this paper systematically summarizes the research status and achievements of orbital remote sensing and mapping of extraterrestrial planets,obstacle avoidance of landing navigation,patrol environment perception and visual navigation.In view of the requirements of future lunar and deep space exploration missions,the development of deep space remote sensing and mapping technology is discussed,including intelligent processing of massive global remote sensing data of extraterrestrial planets,refinement of global control network,high-resolution three-dimensional topography mapping of lunar south pole,multi-sensor-fusion based obstacle avoidance and navigation for landing and patrol.
