一种月球极区陨坑检测的可信度排序方法
A Credibility Ranking Method for Crater Detection in Lunar Polar Regions
摘要
Abstract
The lunar polar regions are crucial for future crewed lunar missions.Given the rich crater features on the lunar surface,crater detection plays a vital role in lunar exploration.However,the complex terrain and numerous permanently shadowed areas in the lunar polar regions challenge the accuracy of crater detection methods.To address this issue,this paper analyzes the peaks and troughs in correlation value matrices.Then,we establish three screening criteria-quantity,illumination,and distance-to filter detected craters.Leveraging the information of peak,trough,and radii,we develop a credibility evaluation function to rank the filtered craters.These steps significantly improve the accuracy of lunar crater detection.We validate our method with experiments.We use images from the Chang'e-2 camera and the lunar reconnaissance orbiter camera,focusing on 6 areas near the Shackleton crater in the lunar south pole.The results are clear:the crater center detection error is under three pixels,the radius detection error is less than one pixel,and the false detection rate is 0,outperforming traditional methods like principal component analysis and bright-dark region matching.Furthermore landing simulation experiments conducted in the lunar polar regions demonstrate that the proposed method achieves an attitude estimation error of less than 1.59°and a position estimation error of less than 38.81 m,validating its effectiveness.关键词
