Design and Implementation of Spatial Scattered Data Interpolation
Yang Pan · Microcomputer Information · 2008
This paper proposed originally a interpolation method of curved surface which is based on Shepard method used together with Clough-Tocher Algorithm.This method used K-nearest neighbor algorithm in pattern recognition to construct triangular pieces,then refined interpolation results with Clough-Tocher interpolation Algorithm,improved the interpolation quality.The result shows that the method can get more accurate surface and be used expediently,makes up for the insufficiency of traditional interpolation algo-rithm.
