Abstract

In order for a robot to operate autonomously in an environment, it must be able to locate itself within it. A robot’s position and orientation cannot be directly measured by physical sensors, so estimating it is a non-trivial problem. There are sensors that provide this information, such as the Global Navigation Satellite System (GNSS) and Motion capture (Mo-cap). Nevertheless, these sensors are expensive to set up, or they are not useful in environments where autonomous vehicles are often deployed. Our proposal utilizes one vision sensor and a fiducial Moiré marker to estimate the position and orientation of the user using deep learning. This approach was tested experimentally in standard hardware for autonomous system achieving a position estimator with 30 Hz refresh rate and a Mean Squared Error of 0.02 meters.
