基于实测图像实时绘制技术的红外烟幕图像仿真

红外烟幕图像仿真是红外成像武器应用领域中的一项重要技术。在典型环境条件下开展了运动目标烟幕红外成像跟踪野外试验。根据某型发烟罐外场试验的实测红外图像和相关数据,针对红外烟幕的自身特点和施放条件的影响,提出了一种可对经典红外烟幕模型进行修正的方法。在视景仿真程序中,利用背景、目标等仿真要素,通过与实测数据对比分析生成了图像库,并使用图像分层实时透明绘制方法实现了对红外烟幕干扰的动态视景仿真。其视景窗口大小为360×240,帧频为40帧/s,可以满足一般成像型红外制导过程的仿真实时性要求。

Simulation of Infrared Smoke Image Based on Real-time Drawing Technique for Measured Images

Infrared smoke simulation is a key technique in the appUcation field of infrared imaging guidance weapons.Under a typical environmental condition,the infrared imaging tracking of the smoke of a moving target is carried out.According to the infrared images and related data obtained in the field test of a given smoke pot,a method for modifying the classic infrared smoke model is proposed. In a scene simulation program,the elements such as background and target are utilized.By comparing them to the measured data,an image database is formed.The dynamic scene simulation of infrared smoke interference is implemented by using a real time layered transparent image drawing method.The simulation uses a scene window of 360×240 and a frame rate of 40 frames per second.It can meet the real time simulation requirement of the conventional imaging infrared guidance process.
