US Patent 10001376 Aircraft position monitoring system and method

An apparatus monitors position for an aircraft. The aircraft includes a display, a position system, a vision system and a database comprising terrain data associated with an environment at a location of the aircraft. The apparatus includes a monitoring processor configured to perform character recognition or structure recognition on the image data to identify a structure or a character in the image data, correlate a position of the structure or character in the environment using a position from the position system and the terrain data, and cause the display to provide a confirmation in response to the position of the structure or character in the terrain data matches the position of the structure or character in the image data.
