Video-Assisted Global Positioning in Terrain Navigation with Known Landmarks

Free registration required

Executive Summary

The authors present a rigorous geometric analysis of the computation of the global positions of an airborne video camera and ground based objects using aerial images of known landmarks. This has also been known as the Perspective-n-Point (PnP) problem. A robust Hough transform-like method, facilitated by a class of CORDIC-structured computations is developed to find the camera position followed by a method of computing the position of a ground object from images of that object and three known landmarks.
