MR code for indoor robot self-localization

A novel 2D code which can be used as an efficient artificial landmark system for indoor mobile robot and is thus called MR (mobile robot) code, is described in this paper. A real time detection-recognition algorithm for this MR code is also proposed. Experiments in cluttered indoor environments under various viewing angles and illumination conditions are carried out to show the effectiveness and robustness of the MR code detection-recognition algorithm proposed. How to use this new MR code for indoor mobile robot self-localization and objects recognition is also discussed and experiments are also carried out to show the feasibility and reliability.
