The invention discloses a three-dimensional terrain acquisition method in a high dynamic landing process of an extraterrestrial celestial body. The three-dimensional terrain acquisition method comprises the steps of building a celestial body fixed connection coordinate system at a T0 moment, compensating system timing system motion and the like. The three-dimensional measurement sensor adopts a scanning scheme based on a swing mirror, and the function of obtaining the landing area terrain in the dynamic landing process is achieved. Therefore, the detector can obtain the landform data of the falling area without hovering, and the fuel consumption of the system is remarkably reduced.

    本发明公开了一种地外天体高动态着陆过程中三维地形获取方法,包括:T0时刻天体固联坐标系建立、系统时统运动补偿等。三维测量敏感器采用基于摆镜式扫描方案,在动态着陆过程中实现了的落区地形获取的功能。使得探测器不用悬停即可获得落区地形数据,显著减少了系统燃料消耗。
