Abstract
Visual landing aids including a series of contrasting circles and polygons for unmanned aerial vehicles that are capable of being accurately detected over a wide range of angles and distances by an unmanned aerial vehicle equipped with a camera and shape detection capabilities. The visual landing said may be implemented using contrasting colors for the pattern which reflect visible and/or UV or infrared light, or by light emitting elements. In some examples, the landing aids includes a secondary smaller version of the landing aid shape pattern that is embedded within the larger pattern, to enable greater detection range while facilitating close-in precision guidance. In still further examples, light emitting elements may be pulsed at a rate that is synchronized with the camera shutter on the unmanned aerial vehicle to further enhance accurate detection.
