Quickbird遥感影像提取建筑物阴影信息的方法改进

The QuickBird RemoteSensing image extracting building shadow Information method improvement

在分析Quickbird遥感卫星图像上多出建筑物阴影与其真实高度的对比关系中,进行了城市建筑物高度信心提取方法的进一步的精确和改进,并且以曹妃甸典型建筑物高度信息提取为例,更加精确地提取出建筑物的阴影和高度信息,从而体现出遥感卫星图像在城市规划中越来越重要的作用。

Highly confident extraction method of the city building is further improved by analdyzing the contrast rela- tions between many building shadows and true altitude on the QuickBird satellite remote sensing image. Taking the typical building height information extraction of Caofeidian as an example, more accurate information of building shadow and height is extracted. Thus the remote sensing satellite images are more and more important in city plan- ning.
