  • Publication number: 20230419845
    Abstract: A system for detecting a foreign object on a runway, the system including a thermal camera comprising a first field of view and adapted to capture a thermal image of a first view of an area of interest on the runway from one side of the runway, a visible light camera comprising a second field of view and adapted to capture a visible light image of the first view of the area of interest on the runway from the one side of the runway, wherein the first field of view overlaps the second field of view, detect a thermal object image in the thermal image, detect a visible light object image in the visible light image, and determine that the foreign object is detected when the thermal object image and the visible light object image are detected in the thermal image and the visible light image respectively.

  • Patent number: 9483952
    Abstract: A surveillance system and method for detecting a foreign object, debris, or damage (FOD) on a runway. The system comprises one or more cameras for capturing images of the runway; and an image processing system for detecting the FOD on the runway based on adaptive image processing of the images captured by the cameras; wherein the surveillance system is adaptively operable for FOD detection under both day and night ambient light conditions without assisted illumination such as infrared or laser illuminators.

  • Patent number: 8005267
    Abstract: An apparatus for the automatic inspection of a motor vehicle has an identification and psychological profiling zone, an automatic inspection zone and a manual inspection zone. A biometric and heart rate detection station and an attached console are located in zone one. Undercarriage scanning equipment and an explosives detection portal are located in zone two. The apparatus also has one or more fixed cameras, an alarm or other alerting mechanisms and a physical barrier. A vehicle detection mechanism detects the entry of a vehicle into zone two and captures an image of the vehicle number plate. When the captured biometric data and number plate data indicate that the driver is authorized to drive the particular vehicle into the secured zone, and if no abnormalities or foreign objects in the undercarriage image are detected, the driver is allowed to proceed.

  • Patent number: 7889232
    Abstract: A surveillance system and method for vessels. The system comprises surveillance means for surveying a waterway; vessel detection means for determining the presence and location of a vessel in the waterway based on information from the surveillance means; camera means for capturing one or more images of the vessel; image processing means for processing the images captured by the camera means for deriving surveillance data; wherein the camera means captures the vessel images based on information from the vessel detection means, the surveillance data from the image processing means, or both. The images can be used to classify and identify the vessel by name and category, possibly also to compare the category with that previously registered for a vessel of this name. The vessel can be tracked, including by speed and direction until it leaves the surveyed waterway.
