| 摘 要： | 根据气象雷达回波数据的三维极坐标分布特点,提出一种改进的Marching Cubes三维重建算法.该算法将Marching Cubes常规算法中的单位正立方体构建转换为直接对回波极坐标数据的拟柱体构建,生成相应的等值三角面,并对三角面的顶点数据进行地曲订正,供OpenGL显示.为进一步提高重建算法的效率,该算法避免了对高仰角远距离无回波区的重建.实验表明,该算法有效实现了雷达回波的三维重建.

| Abstract: | Based on three dimensional polar coordinated distributions of echo data of meteorology radar,an improved Marching Cubes reconstruction algorithm isproposed.In the algorithm,unitcubes of Marching Cubes generalalgorithm are replaced by imitated cylinders,and the data of isosurface generated by the algorithm are corrected by earth curvature before showing with OpenGL.To further improve the algorithm,the non echo data areas with high elevation and long distance are not taken into consideration during reconstruction.The experiment shows the 3D reconstruction of echo data of radar are implemented effectively with the improved algorithm. |
