  • Patent number: 9219858
    Abstract: Generating a composite geo-referenced panoramic field of view image of a geographic area is provided. Geodetic coordinates are generated for each of a plurality of pixels in a digital image capturing the geographic area based on a corrected amount of image distortion in each line of pixels in the plurality of pixels in the digital image. Each of the plurality of pixels in the digital image with the calculated geodetic coordinates is mapped to a geo-referenced map corresponding to the geographic area based on the calculated geodetic coordinates of each pixel. The composite geo-referenced panoramic field of view image of the geographic area is generated based on the mapping of each of the plurality of pixels in the digital image with the calculated geodetic coordinates to the geo-referenced map corresponding to the geographic area captured in the digital image.

  • Patent number: 9047668
    Abstract: A global position of an observed object is determined by obtaining a first global position of an observed object with at least one positioning device. A determination is made as to whether a set of stored visual characteristic information of at least one landmark matches a visual characteristic information set obtained from at least one captured image comprising a scene associated with the observed object. In response to the set of stored visual characteristic information matching the obtained visual characteristic information set, a second global position of the observed object is determined based on a set of stored location information associated with the at least one landmark and the first global position.

  • Publication number: 20150062340
    Abstract: A method and system for demonstrating compliance with a requirement of a high occupancy lane in a vehicle for a reduced toll charge for the vehicle is provided. The system includes a housing, an infrared camera within the housing, a GPS unit, a transceiver and a control within the housing. The infrared camera images one or more people in the vehicle. The transceiver detects an RF signal indicating that the vehicle is located at or near a toll booth for the high occupancy lane. The control triggers the infrared camera to image the one or more people and transmit a current time, a current location of the vehicle from the GPS unit, and the triggered image of the one or more people, to a server to demonstrate compliance with the requirement of the high occupancy lane for the reduced toll charge for the vehicle.
