插值算法在姿态显示图形中的应用
Application of Interpolation Algorithm in Attitude Display Graphics
摘要
针对座舱显示系统姿态指引画面中俯仰线数值、倾斜角指示三角在旋转、平移时出现扭曲、闪烁的现象,提出双线性插值的反向映射法实现图像旋转、平移,并在PC机Windows环境下采用Visual C++开发工具进行仿真,给出了未经插值算法和经过插值算法处理的姿态画面俯仰线数值的对比。实验结果表明,该算法成功解决了姿态指引画面中俯仰线数值、倾斜角指示三角在旋转、平移时的扭曲抖动现象。
Abstract
In attitude guidance picture of the cockpit display system, distortion and flickering may occur to the numerical value of pitching angle and the triangle indicating the angle of inclination in rotation and translation.To solve the problem, reverse mapping method of bilinear interpolation was used for image rotation and translation.Visual C++ was used in the PC Windows environment for simulation.Comparison was made to the attitude pictures before and after the processing of interpolation algorithm.Experimental results showed that the algorithm can effectively restrain the distortion and flickering of attitude display in rotation and translation.
