Research on Robust Registration Algorithm for Point Clouds Based on Kernel Density Estimation
摘要
Abstract
Aiming at the problems of narrow convergence region and robustness in classical point cloud registration algorithms,a new algorithm for point cloud registration was proposed based on kernel density estimation. A new measure was proposed and used to evaluate the similarity between kernel density functions,which provided a smooth bridge between the Kullback-Liebler divergence and the Euclidean distance. The analytical form measure was derived under rigid constraints. The local maximum phenomenon caused by over-scaled parameter and the drifted maximum phenomenon caused by deficiency-scaled parameter were analyzed based on comparative experiments. And then, the variable-scaled BFGS-quasi Newton method was used to search the optimal parameters. Experimental results show that the method can realize point cloud registration, extending the convergence region, meanwhile, improve the robustness under white noise interferences.关键词
