多源数据的嫦娥四号着陆点定位
|
摘要
嫦娥四号着陆点的精确定位对于工程任务安全高效实施至关重要。本文基于嫦娥二号正射影像、LROC NAC正射影像、嫦娥四号降落相机影像、嫦娥四号监视相机影像等多源数据,利用影像特征匹配定位和单像视觉测量定位技术,确定了嫦娥四号着陆点的精确位置为(177.588°E,45.457°S)。本研究结果对综合利用多源数据深入开展着陆区科学研究具有重要意义。
High precision localization of Chang'e-4 lander is critical to support safe and efficient mission operations. This paper presents the lander localization techniques, including image feature matching and monoscopic image measurement, using digital orthophoto maps of Chang'e-2 and LROC NAC images, descent camera images and monitoring camera image of Chang'e-4 lander. The lander location is precisely determined to be(177.588°E, 45.457°S) using these techniques. Localization of the lander in multiple datasets is valuable for synergistic scientific investigation of the landing site.
