  • 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.

  • Patent number: 9307133
    Abstract: An imaging system for increasing image resolution is provided. In one embodiment, the system comprises a camera lens, beam splitters, color image sensors, multiple-DOF (degree of freedom) actuators, and a computational unit. One beam splitter receives light from the camera lens, and each color image sensor receives a split light beam from one of the beam splitters. The color image sensors are configured to individually sense a scene with different focus to yield captured images. Each actuator connects to an individual color image sensor for translating and rotating the individual color image sensor. The computational unit is configured to: compute a geometric transformation among the captured images so as to configure the actuators to align the color image sensors by performing translation and rotation on the color image sensors; and to perform luminance unification on the captured images to output a resultant image.
