    摘要:

    如何利用高分影像構(gòu)建自動(dòng)解譯模型是快速高效獲取空心村建筑物的關(guān)鍵,對(duì)空心村調(diào)查研究具有重要意義。針對(duì)傳統(tǒng)目視解譯需要專業(yè)知識(shí),,效率低、工作量大的問(wèn)題,,提出一種基于詞袋特征的空心村高分影像建筑物解譯模型。首先,,對(duì)比了多種影像特征提取方法,;然后,選取詞袋特征(BoW)和支持向量機(jī)(SVM)構(gòu)建建筑物自動(dòng)解譯模型,;最后,,為檢驗(yàn)方法的有效性,選取空心村高分影像構(gòu)建了建筑物樣本庫(kù),,并基于該樣本庫(kù)進(jìn)行實(shí)驗(yàn)研究,。結(jié)果表明本文方法的分類準(zhǔn)確度可以達(dá)到0.86,所提方法可用于空心村內(nèi)建筑物自動(dòng)解譯,,具有較高的實(shí)用價(jià)值,。

    Abstract:

    With the rapid development of remote sensing technology, remote sensing image resolution has been greatly improved and the ground targets can be obtained from high resolution remote sensing image. But the traditional visual interpretation has low work efficiency and needs for professional knowledge. Thus using high resolution remote sensing image to construct automatic interpreting model is the key to quickly and efficiently obtain the building of hollow village. Meanwhile, it is important for the hollow village renovation and research. Based on this, a novel automatic building interpretation model of hollow village high resolution images based on bagofwords (BoW) was proposed. Firstly, several existing feature extraction methods were compared, and then based on the BoW and support vector machines (SVM) the automatic interpretation model for the building was constructed. In order to verify the validity of this method, the high resolution remote sensing image of typical hollow village was selected to construct the building sample library. Finally, the model for building interpretation was experimentally studied based on the sample library. The results showed that the classification accuracy (ACC) of this method can reach 0.86. Therefore, the proposed method can be used for the building automatic interpretation, and it had high practical value to hollow village research and renovation.
