摘　　要：当前居民点布局侧重于单一时相的考虑,对多时相变化考滤不足,使得布局效果不理想。针对该问题,提出了乡村人居环境适老性居民点布局多时相遥感优化算法。设计适老性居民点布局多时相遥感图像检测过程,获取两相遥感图像差值图像。经过多分辨率分解,分析图像不同尺度检测结果,计算合理布局尺度。提取梯度方向直方图的峰值,识别布局边界线。利用二维Gabor滤波器,获取一组滤波图像幅值,得到多时相遥感图像纹理结果。在像元尺度上,通过相对辐射校正检测图像像素级变化,实现对遥感图像的配准。基于配准结果,采用网格约束方法布设控制点。由案例分析结果可知,该算法居民点布局效果与理想布局效果一致,且IPA指数为0~10,说明本文研究算法取得了理想效果。The current layout focuses on the consideration of a single phase,lacking consideration for multi-phase changes,resulting in the layout effect not reaching the ideal state.A multi-temporal remote sensing optimization algorithm for the layout of aging-friendly residential areas in rural living environments has been proposed to address this issue.Design a multi temporal remote sensing image detection process for the layout of aging-friendly residential areas,and obtain the difference image between the two remote sensing images.After multi-resolution decomposition,analyze the detection results of images at different scales and calculate a reasonable layout scale.Extract the peak value of the gradient direction histogram and identify the layout boundary lines.Using a two-dimensional Gabor filter,obtain a set of filtered image amplitudes and obtain texture results for multi-temporal remote sensing images.At the pixel scale,the registration of remote sensing images is achieved by detecting pixel level changes in the image through relative radiometric correction.Based on the registration results,the grid constraint method is used to lay out control points.According to the case analysis results,it can be seen that the residential layout effect of the algorithm is consistent with the ideal layout effect,and the IPA index is in the range of 0-10,indicating that the algorithm used in the study is very satisfied with the layout of residential areas.
