METHOD FOR AUTOMATIC GEOMETRIC CORRECTION OF CROSS-PLATFORM MOON-BASED EARTH OBSERVATION IMAGING

摘要

By analyzing influential factors of the moon-earth relationship on the geometric distortion of moon-based imaging, and focusing on the influential effects of positional changes of sublunar points, earth curvature, and topographic relief on large-scale hemispherical imaging, and considering the problems that ground control points may be few in number and unevenly distributed, a method of geometrically expressing the projection of polar coordinates for moon-based earth observation imaging while taking into account sublunar point movement is provided, and automatic precision geometric correction of earth observation data from a moon-based platform can be implemented in coordination with earth observation data from multiple platforms.
