RESEARCH ON CORRECTION OF REGESTRATION ACCURACY FOR ELECTROMAGNETIC TRACKER IN AUGMENTED REALITY SYSTEM
摘要
Abstract
Aiming at the relationship among the spatial data of the electromagnetic tracker is complex and fuzzy in magnetic field,the fusion method which combined of BP neural network and least squares support vector machine based on T-S fuzzy system is proposed.This method corrects the registration accuracy of the electromagnetic trackers.First,kmeans algorithm was employed in the cluster analysis,and then T-S fuzzy system was used to pre-process the spatial data in local.Second,training was used by BP neural network in global and the training target of BP neural network was dynamically adjusted by the final correction accuracy.At last,least squares support vector machine was used for solving after preliminary correction.Our results indicate that this method is applicable to nonlinear spatial data correction,which can effectively improve the registration accuracy of electromagnetic tracker and to help improve the accuracy of an interactive system with augmented reality.关键词
