An Estimation Method of the Covariance Matrix for Mobile Robots' Localization

이동로봇의 위치인식을 위한 공분산 행렬 예측 기법

  • Published : 2005.05.01

Abstract

An empirical way of a covariance matrix which expresses the odometry uncertainty of mobile robots is proposed. This method utilizes PC-method which removes systematic errors of odometry. Once the systematic errors are removed, the odometry error can be modeled using the Gaussian probability distribution, and the parameters of the distribution can be represented by the covariance matrix. Experimental results show that the method yields $5{\%}$ and $2.3{\%}$ offset for the synchro and differential drive robots.
