A Method of Real-Time Image Correction for Multi-aircrafts Cooperative Detection

Abstract

Abstract. Aiming at the problem of the geometric distortion of the real-time image under the condition of multi-aircrafts cooperative detection, an effective method for the geometric correction is proposed. First multi-aircrafts cooperative terminal guidance model is established, especially the relationship between terminal detection angle and the initial position. Second the detecting angle model combined with the actual parameters, is analyzed, then put forward a real-time image geometric correction method; Simulation of the detection angle geometric distortion is applied to real-time image. Last using normalized product correlation algorithm for a large number of matching simulation, then get matching threshold, a real-time image geometric correction experiment is carried out. The simulation results show that the proposed method is effective,which provides theoretical basis for the reformation of reference image and the further improvement of the algorithm.
