摘要
在分析IKONOS卫星图像上建筑物阴影与实际高度关系的基础上,阐述了估算城市建筑物高度的原理和方法,并在以北京市中关村、天坛公园和北海公园为例的试验中,较为准确地得到了建筑物高度信息,从而显示出卫星遥感在城市园林规划与环境数值模拟等方面应用的巨大潜力。
Based on an analysis of the relationship between the building heights and the shadows in IKONOS image, this paper presents the principle and the method for the estimation of building heights in a city from the shadows of an image. A fairly accurate result was achieved in applying this technique to extracting building height information from Zhongguancun area, Tiantan Park and Beihai Park in Beijing. The achievements made demonstrate the great application potential of satellite remote sensing in garden designing and numerical simulation of the urban garden environment.
