ABSTRACT:
Methods and apparatus are provided for locating a runway by detecting an object (or blob) within data representing a region of interest provided by a vision sensor. The vertices of the object are determined by finding points on the contour of the object nearest for the four corners of the region of interest. The runway can then be identified to the pilot of the aircraft by extending lines between the vertices to identify the location of the runway.
