基于分析因俯仰角、滚转角、偏航角等无人机姿态角变化对下视景象余辉处理图产生的影响．在构建下视景象成像几何畸变数学模型的基础上，本文阐述了一种下视景像姿态畸变的余辉处理的模拟仿真方法，以获得规律性变化的余辉线段。通过对随机亮点图进行不同姿态角的余辉仿真，得到余辉仿真图。仿真实验结果验证了该方法的正确性，不同无人机姿态的余辉仿真得到特征各异的余辉图。

In order to analyze the influence of UAV (Unmanned Aerial Vehicle) attitudes such as pitching, rolling and yawing variation on afterglow effect image of downward-looking scene image. In the paper, based on establishing the imaging mathematical models of downward-looking scene image, a method for simulating afterglow effect on attitude aberration of downward-looking scene image, to get afterglow according to fixed law is dissertated. Simulating afterglow effect on different attitudes variation of the image of randomly distributed highlight is to get afterglow effect images. The results of simulation have verified accuracy of the method and afterglow effect simulation with different UAV attitudes produces afterglow effect image with various characteristics.
