| 摘 要： | 首先获取遥感影像并进行几何校正与配准,再基于八剖面临近点计算法提取高精度的DEM,然后利用ArcScene的可视化功能,从而实现了影像数据的三维可视化显示。使用八剖面临近点计算法进行提取DEM,除了可以减少"阶梯"地形带的误差,还大大提高了地形的三维可视化的精度。

| Abstract: | The main content of this article is to obtain the remote sensing image and geometric correction and image registration, and then extract high precision DEM based on improved eight profile calculation method, and then use the visual function of ArcScene, so as to realize 3D visualization of image data display. The use of the improved eight profile calculation method to extract DEM, in addi-tion to prevent the "ladder" terrain with the error, but also greatly improve the accuracy of the terrain 3D visualization. |
