Abstract

Selecting key point in airplane target as tracking aimpoint at end term is important for IR imaging missiles to improve guidance accuracy. A new aimpoint selection method proper for engineering application is proposed in this article. Other than tracking the center of plume which is the most marked property of airplanes, some point near engine is selected as aimpoint. Firstly plume and skin are extracted by using different thresholds according to their gray scale statistics and features like circularity, distance ratio and central axis are obtained to classify the image types. Then referring to these image types, the centroid of the segmented sector or a point on the line of central axis of plume sector are selected as aimpoint respectively. The algorithm has the advantage of more efficiency in both space and time consuming. Tests have shown the validity of the algorithm.
