  • Patent number: 10891727
    Abstract: An automated airfield ground lighting inspection system and method is disclosed. An image acquisition means captures image streams of the airfield ground lighting system lights when moved across an airfield. A location sensor detects positional information for the image acquisition means when capturing the plurality of images comprising the image streams. An image processor coupled to the image acquisition means and the location sensor processes the image stream of a light of the airfield ground lighting system by: (a) associating characteristics of a plurality of points in an image with an item in the light to be checked, and using this association for extraction of the points; (b) verifying each extracted point; and (c) determining the state of the light of the image stream by processing the verified extracted points comprising an item to be checked.
