Abstract
A method for estimating a position of a target by using an image acquired from a camera is provided. The method includes the steps of: (a) setting multiple virtual estimated reference points by dividing a view-path; (b) comparing altitude values of the respective estimated reference points with those of respective points on terrain; (c) searching neighboring virtual estimated reference points among the multiple virtual estimated reference points to satisfy a requirement under which a difference between an altitude zk of one point among the neighboring estimated reference points and that of the terrain corresponding thereto and a difference between an altitude zk+1 of the other point among the neighboring estimated reference points and that of the terrain corresponding thereto have different signs; and (d) determining that the actual position of the target exists between the searched estimated reference points Pk.
