针对密度值信息的建筑物变化研究

Research on Building Change Against Density Information

为准确获取不同时间、同一位置影像中的建筑物变化情况,研究一个检测方法是十分必要的。本文基于影像中建筑物所在的区域密度与其它物体不同,探讨了一种基于依据密度值信息探测建筑物变化的检测方法。实验结果表明:在仿真模型和真实影像的建筑物变化状况探测中,均检测到建筑物的变化情况,且效果良好。

In In order to accurately obtain the changes of buildings in images at different times and at the same location,it is necessary to study a detection method.Based on the difference between the density of the area where the building is located in the image and other objects,this paper discusses a detection method for detecting building changes based on density information.The experimental results show that in the detection of building changes in both simulation models and real images,changes in buildings are detected,and has proved quite effective.
