  • Publication number: 20250218028
    Abstract: In one embodiment, a method includes receiving an image generated by a camera associated with a vehicle. The image includes a point of interest (POI) associated with a physical object. The method also includes determining a number of pixels from the POI of the image to an edge of the image. The edge of the image represents a location of the camera. The method further includes determining an offset distance from the POI to a Global Positioning System (GPS) unit associated with the vehicle using the number of pixels.

  • Publication number: 20240124035
    Abstract: In one embodiment, a method includes identifying, by an image detection tool, a tank within an image of a railway environment and identifying, by the image detection tool, a railroad track within the image of the railway environment. The method also includes determining, by the image detection tool, a distance between the tank and the railroad track and comparing, by the image detection tool, the distance between the tank and the railroad track to a predetermined threshold distance. The method further includes determining, by the image detection tool, that the tank presents a hazard to the railway environment in response to comparing the distance between the tank and the railroad track to the predetermined threshold distance.
