高分辨率遥感影像提供了地物更丰富的信息,包括光谱信息、地物结构、形状、纹理以及地物之间的空间关系等多方面的信息。面向对象的影像分析方法以目标地物为研究对象,充分考虑目标地物的形状、结构及空间关系等信息进行目标的提取和分析,是当前高分辨率信息提取技术的主要方法。研究了采用面向对象目标的思想将MRF方法应用于高分辨率遥感影像的道路目标提取中,并进行了道路提取实验。
High-resolution remote sensing images provide a wealth of information about the features, including spectral information, features, features, shapes, textures, and the spatial relationships between features. The object-oriented image analysis method takes the target object as the research object, and takes the target object shape, structure and spatial relationship into consideration to extract and analyze the target information. It is the main method of the current high-resolution information extraction technology. The idea of object-oriented is applied to apply the MRF method to the road target extraction of high-resolution remote sensing images, and the road extraction experiment is carried out.
