ATTITUDE ANGLE SENSOR THREE-DIMENSIONAL MISALIGNMENT CORRECTION METHOD USING SINGLE IMAGE

摘要

The present invention relates to attitude angle sensor misalignment correction method using a single three-dimensional image, especially ship ( Spacecraft) or aircraft (Aircraft) single image calculation ground control point (Ground Control Point) from a single image information photographed in the image pickup camera mounted on the vehicle to which the three-dimensional misalignment correction to quantitatively extract the position information of each sensor, such as a . Using the three-dimensional attitude angle sensor misalignment correction relates to a method ; the configuration of the present invention, the calculation step of the ground control point reference vector; Calculation step of the ground control point observation vector using image information; The attitude error matrix calculation step using the ground control point reference vector and the calculated the ground control point observation vector; And correcting attitude angle sensor misalignment using the attitude error matrix calculation step value; according to the three-dimensional misalignment correction method of an attitude angle sensor using a single image comprising a, in the calculation step of the ground control point reference vector, the earth coordinate system (Earth Centered aircraft position vector Earth Fixed Coordinate System) () and ground control point locations vector () ground control points using the reference vector () the following equation: is characterized in that the calculation by.
