Mobile robot applied to QR landmark localization based on the keystone effect

Abstract

This paper proposes a method for the localization of QR (Quick Respond) landmark based on the Keystone Effect (KE) for real-time positioning applications. This is an important aspect, whose solution is still necessary for improving performance in autonomous landmark-based navigation tasks. The paper presents an experimental analysis of the localization of QR landmark and discuss the results which minimize the keystone distortion related to the precision of estimating the landmark’s position in a given environment. Through the experiment, the use of proposed algorithm in performing landmark-based robotics action tasks by a Seekur Jr mobile robot is demonstrated.
