【摘要】：在遙感圖像中,災區(qū)建筑物的檢測對災情獲取和災后應急救援具有重要意義。針對災區(qū)高分辨率遙感圖像中建筑物檢測的問題,提出了一種改進的基于形態(tài)學特征的多方向和多尺度分割方法,以實現(xiàn)災區(qū)建筑物的自動化檢測。首先將形態(tài)學算子的重建、粒度和方向等性質(zhì)整合到建筑物的亮度、大小和對比度等特征中,對遙感圖像進行初步的分割并提取高亮和高對比度的建筑物,然后結(jié)合圖像的區(qū)域邊緣信息,進一步提取潛在的建筑物。實驗結(jié)果表明,所提方法對災區(qū)高分辨率圖像中的建筑目標有較高的檢測率和較低的誤檢率。
[Abstract]:In remote sensing images, the detection of buildings in disaster areas is of great significance to disaster situation acquisition and emergency rescue. In order to solve the problem of building detection in high resolution remote sensing images of disaster areas, an improved multi-direction and multi-scale segmentation method based on morphological features is proposed to realize the automatic detection of buildings in disaster-stricken areas. Firstly, the reconstruction, granularity and direction of the morphological operator are integrated into the luminance, size and contrast of the building to segment the remote sensing image and extract the high-contrast and high-contrast buildings. Then combined with the region edge information of the image, the potential buildings are further extracted. The experimental results show that the proposed method has higher detection rate and lower false detection rate for building targets in high resolution images of disaster areas.
