高分辨率卫星图像中制图目标的提取用于目标模型生成

Extraction of cartographic objects in high resolution satellite images for object model generation

Guray Erus, Nicolas Loménie

摘要:

本研究的目的是检测高分辨率卫星图像中的人造制图对象。新一代卫星提供了亚米制空间分辨率,其中有可能(也有必要)在物体一级而不是像素一级开发方法,并利用物体的结构特征。为此,提出了一种从人工分割的图像中生成结构物体模型的方法。为了从非分割图像生成模型,需要从样本图像中提取对象。提出了一种混合提取方法(输入源和分割算法):基于区域的分割应用于10米分辨率的多光谱图像。将结果用作2.5米分辨率全色图像上的“使用边缘的标记控制分水岭方法”中的标记。即使在目标物体的界限不明显的图像上也取得了非常有希望的结果。

英文摘要:

The aim of this study is to detect man-made cartographic objects in high-resolution satellite images. New generation satellites offer a sub-metric spatial resolution, in which it is possible (and necessary) to develop methods at object level rather than at pixel level, and to exploit structural features of objects. With this aim, a method to generate structural object models from manually segmented images has been developed. To generate the model from non-segmented images, extraction of the objects from the sample images is required. A hybrid method of extraction (both in terms of input sources and segmentation algorithms) is proposed: A region based segmentation is applied on a 10 meter resolution multi-spectral image. The result is used as marker in a "marker-controlled watershed method using edges" on a 2.5 meter resolution panchromatic image. Very promising results have been obtained even on images where the limits of the target objects are not apparent.
