Computer dynamic infrared image generation of sea background

摘要

Abstract: In the simulation of tracking a target such as a ship with infrared imager in the sea environment, how to generate dynamic images of the target and background is the key issue. The radiation of the scene includes the radiation of the target, sky, and seawater. All of these radiation can be obtained with the software - LOWTRAN7. A method of laser quantification is used to convert the radiance into gray- scale. The gray-scale of anywhere and anytime is computed beforehand and stored as a database. Establishing the 3D model of the target and background is necessary. The scene can be established through 3D transformation. We program with OpenGL in Windows NT operating system. The material of the objects is emitted material and its value is equal to the gray-scale. During the course of animation, the material and the position of the scene changed frequently. It is interactive.!9
