利用高分辨率遥感图像阴影信息提取建筑物高度

Extracting Buildings Distribution Information of Different Heights from the Shadows in High Resolution Images

利用全色高分辨率卫星影像数据中的阴影信息进行建筑物高度计算的原理和方法 ,并结合专家分类系统 ,研究了如何进行建筑物阴影、顶部和建筑物向阳面分类 ,并计算出建筑物的高度 .从试验区得结果表明 。

Based on the analysis of the relationship between the building heights and the shadows in the high resolution images, this paper discusses the principle and the method for getting the high of the building form the shadow of the building. Different from the previous studies mentioned in published articles, expert classifier is used to classify the shadow and the buildings in this paper. A result has been achieved while applying this technique to the practice place.
