Study on Geomagnetic-Matching Technology Based on ICP Algorithm

Charles Okanda Nyatega ^[3] | Li Shi Xin ^[2]

Abstract: ICP (Iterative Closest Point) is a kind of image matching algorithm presented by Besl and McKay, Chen and Medioni and Z. Zhang at the same period [1]. Proposed algorithm was put forth in the image alignment, position estimation and other image processing algorithms which have been widely used especially in terrain match and gravity match, the aim is to improve the current existing basic navigation system INS (Inertia Navigation System) since INS is able to provide a real-time navigation information with good short-term accuracy, however the errors accumulates with time, to solve this, GPS (Global Positioning System) was introduced but still cannot correct this because it cannot work in the absence of satellite, also Terrain matching even though gives position information which is helpful for vehicle safety, but still doesn-t work well when the vehicle sails on water. To correct INS errors we propose the new aided navigation system using ICP algorithm with real-time measurement data and computer simulations.
