【摘要】：正建筑區(qū)檢測是城市遙感領域的一項重要課題,高精度的建筑區(qū)信息具有重要的應用價值。在高分辨率影像中,同物異譜與異物同譜現(xiàn)象導致光譜、紋理、形狀等平面特征對不同類地物的區(qū)分性降低,進而也降低了建筑區(qū)與非建筑區(qū)之間的區(qū)分性。建筑區(qū)的建筑物等地物通常高于周圍地表,而高度信息有利于提高不同類地物之間的區(qū)分性,因而高度信息有利于提高建筑區(qū)與非建筑區(qū)之間的區(qū)分性。結合高度與平面信息進行建筑區(qū)的聯(lián)合檢測,能提高建筑區(qū)檢測精度。
[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.
