基于Delaunay三角剖分和ICP的星图运动补偿算法
A New Starry Images Motion Compensation Method Based on Delaunay Triangulation and ICP
摘要
Abstract
Motion compensation method for starry image registration is one of the key technologies,which could effectively improve the dim target detection precision in complex background for space surveillance.In this paper,a new method combining with Delaunay triangulation and ICP algorithm is presented for starry images sequences motion compensation.Firstly,this method establishes the clue matrix for several fixed stars in one starry image by Delaunay triangulation.Secondly,this method could get the corresponding relations between the adjacent starry maps by using the ICP registration algorithm.And through the SVD optimal resolution to get the transform relation between the adjacent frames which is the camera motion model.Finally,the bilinear interpolation method is employed to finish the motion compensation.The experimental results show that,this method can effectively realize high precision motion background compensation,and lay the technical foundation for dim small target detection in complex background.关键词
