摘要
Abstract
Aiming at traditional 3D terrain modelling characteristics such as time consuming,difficult in eigenvalue extraction and poor modelling effect,we put forward the contour sketch-based improved method for 3D terrain modelling.The system analyses the geometric char-acteristics of contour with Douglas-Peucker algorithm,and denoises the reconstructed 3D terrain with Gauss high-pass filter.Experimental re-sults showed that the 3D terrain model generated by this method had good visualisation effect,and proved as well that the Douglas-Peucker al-gorithm is suitable for the analysis of outlining,decomposing and reconstructing contour,and that Gauss high-pass filter has good effect on ter-rain smoothing.关键词
