This paper deals with navigation indoors and in small-scale outdoor scenes. We propose to enhance IMU and conventional visual odometry navigation - typically used in the said contexts - by visual location estimation based on markers conveniently displaced in the environment. We propose using visually appealing Uniform Marker Fields; this technique offers high precision and real-time performance on mobile devices of moderate computational power. We evaluate the accuracy of the proposed technique, achieving approximately 4cm error in a scene of roughly 5 m diameter (beneath 1 %).
