Infrared Sequence Simulation Method for Aerial Moving Platform Target Scene

Abstract

Infrared flight image sequences are the basis of flight guidance and target detection and recognition, but real infrared image sequences are not easy to obtain. So a flight vehicle infrared sequence simulation method is proposed to get 3D model of ground target by 3DMax simulation modeling, and analyze the target infrared characteristics, use ANSYS to calculate the temperature field of the target, then input it to the infrared radiation calculation module, and output the infrared radiation image. The positive downward looking infrared background is selected, the geodesic coordinate system is established, and the flight trajectory of the vehicle is simulated, the Euler angle between the vehicle and the ground target in the trajectory is calculated, and the simulated infrared sequence is obtained by using perspective transformation according to the Euler angle.
