【摘要】：正建筑区检测是城市遥感领域的一项重要课题,高精度的建筑区信息具有重要的应用价值。在高分辨率影像中,同物异谱与异物同谱现象导致光谱、纹理、形状等平面特征对不同类地物的区分性降低,进而也降低了建筑区与非建筑区之间的区分性。建筑区的建筑物等地物通常高于周围地表,而高度信息有利于提高不同类地物之间的区分性,因而高度信息有利于提高建筑区与非建筑区之间的区分性。结合高度与平面信息进行建筑区的联合检测,能提高建筑区检测精度。
[Abstract]:The detection of positive building area is an important subject in the field of urban remote sensing. High precision information of building area has important application value. In high resolution image, the phenomenon of isospectral and foreign body isomorphism leads to spectrum and texture. The difference between building and non-building areas is also reduced by the difference between the shape and plane characteristics of different types of features. Buildings in building areas are usually higher than the surrounding surface. The height information is helpful to improve the distinction between different types of features, so height information is helpful to improve the distinction between the building area and the non-building area. Combined with the height and plane information, the joint detection of the building area is carried out. It can improve the detection accuracy of building area.
