Abstract
Methods, devices, and systems are presented for determining a distance to an object using a color camera and special markers mounted on the object that refract or reflect different colors depending on the angle at which they are viewed. Different colors can be refracted or reflected using lenticular lenses or other technologies. The color received by the camera reveals the orientation of the markers. The orientation information can be combined with the perceived angular distance between the markers and the known distance between the markers to determine the actual distance to the object.
