利用高分辨率遥感影像提取建筑物方法研究

随着航空航天技术的发展,人们获取的遥感影像数据的空间分辨率不断提高,同时获取难度大幅降低。在遥感数据日益普及的今天,利用影像处理与分析技术对高空间分辨率遥感影像中的感兴趣目标进行自动提取已经成为目前遥感领域研究的热点之一。建筑物作为与人类生活密切相关的主要人工地物,是城市发展的重要标志。目前,通过对高分辨率遥感影像进行建筑物自动提取已经成为建筑物信息获取的重要手段,而建筑物信息可用于进一步研究城市的扩张与发展、城市土地利用现状与变化、城市规划、城市热岛效应、人口估计与预测、灾害监测预警与评估等。

State-of-the-art in Building Extraction from High-resolution Remote Sensing Images

With the development of aeronautics and astronautics, the spatial resolution of remote sensing images is increasing, and the difficulty in obtaining data is reduced.Today, with the growing popularity of remote sensing techniques, the automatic extraction of ROI from high-resolution remote sensing images has become research focus.Buildings, which play an important role in human daily life, mark the urban development.Currently, the automatic building extraction from high-resolution remote sensing images has be-come an important means in urban studies, such as urban sprawl, urban planning, urban heat island effect, population estimation and damage evaluation.
