航空物探平面立体阴影图的绘制

摘要

The shaded relief map can enhance the gradation and reality sense of the grid data,and the realistic three-dimensional grid data show the effect of the airborne geophysical interpretation of a wide range of integrated applications.Based on the principle of the drawing of the shaded relief map,the authors realized the drawing of the map,and compared the application effect between the image fusion and the image enhancement technique in the formation of the image.Through the application of the interpolation technology,the display technology and parallel algorithms can improve efficiency and ensure the display effect.%立体阴影图能够增强网格数据的层次感、真实感，使网格数据具有三维逼真显示的效果，在航空物探综合解释中具有广泛应用。在研究立体阴影图绘制原理的基础上，笔者实现了阴影图绘制，比较了图像融合和图像增强技术在阴影图中的应用效果。通过插值技术、区域显示技术和并行算法的应用提高了显示效率，保证了显示效果。
