“Chang'e-4 lander achieves high-precision localization, crucial for mission safety and efficiency. The paper introduces localization techniques using Chang'e-2 and LROC NAC images, as well as Chang'e-4 camera images, determining the lander's precise location at (177.588°E, 45.457°S). This multi-dataset localization is valuable for comprehensive scientific exploration of the landing site.”
摘要: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.
