| 摘 要： | 针对许多领域对建筑物信息更新的迫切要求,提出并发展了一套完整的基于高分辨率遥感影像的建筑物二维轮廓快速提取流程。首先介绍一种利用数学形态学理论进行边缘检测和边缘连接的新方法,然后利用了模式识别和图像分析领域的相关技术(区域标识和特征量测等)进行建筑物二维信息的提取。最后通过Quickbird影像进行了方法验证,试验证明该流程可以快速有效的提取建筑物轮廓信息。

| Abstract: | To meet the urgent demand in many fields for the building information updating, a set of high-resolution remote sensing image based 2D building outline fast extraction method is developed. In this paper, we first introduce a mathematical morphology theory based new method of edge detection and edge linking. Then we use the relevant pattern recognition and image analysis techniques (region label and feature measurement etc.) to conduct 2D building information extraction. The method is verified us- ing Quickbird image and it is proved by experiments that the method can extract the building outline in- formation rapidly and effectively. |
