Abstract
To the issue of the adaptability of a single reference image under the condition of multi-aircraftcondition of cooperative terminal guidance, an effective method of reference image adaptability evaluation was presented. The model of multi-aircraft cooperative guidance was established, with focus on analyzing the relationship between detection angle and initial aircraft position. A method for analyzing the adaptability of reference image was proposed based on actual parameters and the model of detection angle. Geometric distortion was applied to the real-time images, and the threshold angle was obtained through a lot of scene matching simulation experiment by using the normalized product correlation algorithm. Simulation verified the feasibility of the method, which provided a theoretical basis for real-time image correction, reference image reformation and adaptive algorithm improvement.
