基于人工离线特征库的室内机器人双目定位
Binocular localization of indoor robot based on artificial offline feature-database
摘要
Abstract
In this paper, a binocular vision localization method adopted in a comprehensive environment with dense feature points is proposed in order to address the problem of mobile robot localization in a complicated indoor envi-ronment.To overcome the computational complexity difficulties at the moment when more feature points with a weak ability to data association existing, which establishes a feature-database by an artificial offline algorithm, was de-signed on the basis of the extended Kalman filter-simultaneous localization and mapping ( EKF-SLAM) method. Improvement measures for the sparse control mechanism and salient feature point selection were introduced in order to guarantee the distributed-uniformity of feature points and controllable feature-database.The test result revealed that this algorithm can realize real time positioning with high reliability and accuracy.Moreover, in this method, a periodically updated strategy was employed in order to achieve adaptation to environmental changes.Therefore, long-term effective localization could be realized.关键词
