Abstract
A navigation system uses markers that are identifiable in images of an environment being navigated to determine the location of a portable device in the environment. The portable device takes images of the environment, and those images are analysed to identify markers in the images and the pose of the portable device based on the image of the marker. The identified marker and the determined pose of the portable device are then used to determine the location and orientation of the portable device in the environment being navigated.
