AIDED NAVIGATION APPARATUS USING 3 DIMENSIONAL IMAGE AND INERTIAL NAVIGATION SYSTEM USING THE SAME

摘要

PURPOSE: A 3D image auxiliary navigation device and an inertial navigation system are provided to calculate a distance from a current position to a target object on the ground by using a viewing angle difference at two spots with respect to the target object on the ground in which location information is known and to calculate errors between the location information and the current location calculated by an inertial navigation system based on the calculated distance. CONSTITUTION: A 3D image auxiliary navigation device and an inertial navigation system comprise an inertial navigation device(170), an image sensor(110), a 3D image auxiliary navigation device(130), and an induction control device(150). The inertial navigation device calculates a current location of a flight vehicle. The image sensor is installed in the flight sensor, thereby photographing a target object in which location information is known. The 3D image auxiliary navigation device calculates a location information error of the calculated current location and the actual current location based on viewing angle measurement values of two spots of the image sensor with respect to the target object on the ground. The induction control device extracts an optimal condition of each factor used for calculating the location information deviation minimizing own errors with respect to the calculated location information and controls the flight vehicle in order to move according to the extracted optimal condition.
