METHOD OF CORRECTING THREE-DIMENSIONAL ERRONEOUS ARRAY OF ATTITUDE ANGLE SENSOR BY USING SINGLE IMAGE

摘要

<P>PROBLEM TO BE SOLVED: To provide a method of correcting a three-dimensional erroneous array of an attitude angle sensor by using a single image, in which a ground control point is computed from single image information imaged by an image taking camera mounted on a flight vehicle, and three-dimensional erroneous array information of the attitude angle sensor is quantitatively extracted and corrected. Ž<P>SOLUTION: The method includes steps of: computing a ground control point standard vector; computing a ground control point observation vector by using image information; computing an attitude error matrix by using the computed ground control point standard vector and the ground control point observation vector; and correcting the attitude angle sensor erroneous array by using the computed value of the attitude error matrix.
