Smoke Screen Image Modeling Based on Cellular Automaton

针对成像制导仿真中烟幕模型的实时性与仿真细节兼顾方面的问题,提出了基于元胞自动机理论与技术的烟幕成像模型构建方法。该烟幕成像模型建模方法根据典型烟幕类型、环境条件下的成像特点,依据其消光机理确定相应简化模式,完成基于元胞自动机烟幕模型的各组成要素构建,根据实际试验实测图像相关数据,确定烟幕模型中元胞的离散状态、邻居和扩散规则,和风向、环境等因素对元胞规则的影响及其修正原则。使用C++builder2007软件进行的动态视景仿真验证结果表明,以该方法建立的烟幕模型较好地兼顾了仿真细节与实时性的要求。仿真窗口不小于320×240,帧频不小于40F/s,可以满足成像制导仿真过程的烟幕成像要求。

In order to solve the problem of smoke screen simulation at real-time and detailed describe, according to the characters of smoke screen and the conditions of the smoke loading, this paper proceeded a new way to modify the classic smoke screen model with the images and data got from field tests. Depend on all those charac- ters, the independence states and the expend rules of cellular automaton for the smoke screen mode[ was set up. And all influence factors such as winds and environment were included in the rules to modify the cellular automa- ton models. The simulation program was written with C＋＋builder2007 and compare with the smoke field test data. The simulation result has the window of no less than 320 N 240 and the speed of no less than 40 frames per second. It could satisfy the need of real-time in the progress of the imaging weapons guidance.
