基于遥感图像散乱数据点的三角曲面片插值构造

基于散乱数据点集构造三角插值曲面的方法，在CAD／CAM、科学计算可视化、图像处理等领域有着广泛的应用。本文介绍一种基于遥感图像散乱数据点的三角曲面片插值构造方法。该方法通过在遥感图像上选取局部极值点来构成平面散乱数据点集，并在此基础上进行三角剖分、优化和三角插值曲面构造。此方法在海洋遥感图像多尺度分解处理应用中取得了较为理想的结果。

Triangular Interpolating Surface Construction of Scattered Data Points Based on Remote Sensing Image

The triangular interpolating surface construction based on scattered data points has extensive applications in CAD/CAM, scientific visualization, image processing. This paper will present a method to make the triangular interpolating surface based on scattered data points of remote image. It gets the plane scattered data points through selecting the local extremum points on the remote image, and then triangulates, constructs the triangular interpolating surface on it. It uses in the application of ocean remote sensing image multi-scale decomposition, and gets a good result.
