【摘要】：在遙感圖像中,災(zāi)區(qū)建筑物的檢測(cè)對(duì)災(zāi)情獲取和災(zāi)后應(yīng)急救援具有重要意義。針對(duì)災(zāi)區(qū)高分辨率遙感圖像中建筑物檢測(cè)的問題,提出了一種改進(jìn)的基于形態(tài)學(xué)特征的多方向和多尺度分割方法,以實(shí)現(xiàn)災(zāi)區(qū)建筑物的自動(dòng)化檢測(cè)。首先將形態(tài)學(xué)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(duì)比度等特征中,對(duì)遙感圖像進(jìn)行初步的分割并提取高亮和高對(duì)比度的建筑物,然后結(jié)合圖像的區(qū)域邊緣信息,進(jìn)一步提取潛在的建筑物。實(shí)驗(yàn)結(jié)果表明,所提方法對(duì)災(zāi)區(qū)高分辨率圖像中的建筑目標(biāo)有較高的檢測(cè)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.
