摘　　要：针对目前高分辨率遥感影像变化检测中存在的问题,本文提出了一种基于地物分布特征的违法用地变化检测方法。为了提高违法用地检测精度与稳健性,在变化检测模型中加入违法用地判别特征知识,针对不同的影像光谱-空间特征区域使用不同的变化检测方法。选择杭州市某地两组高分辨率遥感影像进行试验,结果表明相比于其他两种方法,本文方法在违法用地检测中的精度更高,能够快速实现疑似违法用地图斑的定位,将本文方法作为违法用地相关类变化检测作业的辅助可有效降低人工工作量,提高作业效率。Aiming at the problems existing in the current change detection of high-resolution remote sensing images,this paper proposes an illegal land use change detection method based on the distribution characteristics of ground objects.In order to improve the accuracy and robustness of illegal land use detection,the knowledge of illegal land use discrimination features is added to the change detection model,and different change detection methods are used for different image spectral and spatial feature areas.Two groups of high-resolution remote sensing images of a certain place in Hangzhou are selected for the experiment.The results show that compared with the other two methods,this method has higher accuracy in the detection of illegal land,and can quickly locate the suspected illegal map spots.Taking this method as an auxiliary to the detection of changes related to illegal land can effectively reduce the manual workload and improve the operation efficiency.
