【摘要】："中国首次月球探测工程全月球影像图"是我国第一幅覆盖月球的遥感影像图,将成为嫦娥工程后期探测和月球科学研究的重要基础图件.详细介绍了嫦娥一号CCD图像数据的获取、数据特点和数据质量,描述了图像数据的处理方法和流程,按制图规范对图像数据进行了镶嵌拼接和处理,制作了覆盖全月球的1:250万比例尺影像图,并进行了影像图的定位精度分析.数据处理和制图结果表明,嫦娥一号CCD数据及其定位精度能够满足1:250万比例尺的制图要求,制作的"中国首次月球探测工程全月球影像图",其相对定位精度优于240m,平面定位精度约为100m～1.5km,定位精度略好于2005联合控制网(ULCN2005)和克莱门汀基础地图(2.0版);对所有像元进行了逐一光度校正,大大改善了全球图像的一致性,是目前覆盖最全、图像质量最好、定位精度最高的全月球影像图.
[Abstract]:"the whole Moon Image Map of the first Lunar Exploration Project in China" is the first remote sensing image map covering the moon in China. It will become an important basic map for the later exploration of the Chang'e project and the scientific research of the Moon. This paper introduces in detail the acquisition, characteristics and quality of Chang 'e-1 CCD image data, describes the processing method and flow of the image data, and makes mosaic and processing of the image data according to the cartographic specification. A 1: 2.5 million scale image map covering the whole moon has been made and the positioning accuracy of the image map has been analyzed. The data processing and mapping results show that the Chang 'e-1 CCD data and its positioning accuracy can meet the mapping requirements of 12: 2.5 million scale. The relative positioning accuracy of the "whole Moon Image Map of China's first Lunar Exploration Project" is better than 240 m. The accuracy of plane positioning is about 100mb ~ 1.5km, which is better than that of ULCN2005 (2005) and Clementine (2.0). All the pixels are corrected one by one, which greatly improves the consistency of the global image. It is the lunar image with the most complete coverage, the best image quality and the highest positioning accuracy.
