小天体建模约束条件下的观测规划方法研究
Observation Planning Methods Under Modeling Constraints of Small Celestial Bodies
摘要
Abstract
Three-dimensional models of deep space small bodies are crucial scientific data obtained through exploration missions.Due to the large amount of observation image data required for modeling and the high requirements for survey conditions and imaging quality,the probe needs to undergo frequent orbital maneuvers to obtain images that meet the requirements.Therefore,it is necessary to consider multiple factors such as solar illumination angle,imaging coverage rate,fuel consumption,and the cost of data transmitted via downlink,etc.This paper proposes an observation planning method for photometric modeling based on the principle of Stereophotometry(SPC)for small bodies.Based on the low-resolution 3D model obtained from remote detection modeling,a genetic algorithm is used to plan a detailed survey plan for the detector at close range.This method provides an efficient imaging strategy that considers coverage and shadowing relationships,effectively improving the observation efficiency in the surveying process.While meeting the requirements of 3D reconstruction accuracy,it also reduces the need for orbit maneuvering and the transmission of image data.关键词
