基于3D Zernike矩的快速地形匹配算法
A fast terrain matching algorithm based on 3D Zernike moment
摘要
Abstract
In view of the current terrain matching algorithm based on 3D Zernike moment,which is computationally heavy and has poor real-time performance,this paper proposes a fast calculation method of 3D Zernike moment for terrain matching and a matching method that only uses odd-order descriptors to form feature vectors.The forming of method is based on the analysis of the computational process of 3D Zernike moments and the performance of odd-order descriptors.The simulation results show that the fast algorithm proposed in this paper can not only significantly reduce the amount of computation,but also improve the matching accuracy.关键词
