| 摘 要： | 针对城市中疑似违章建筑物信息提取的问题,提出了一种基于多尺度分割方法提取疑似违章建筑信息的新算法.该算法首先通过设置多尺度分割参数对遥感影像进行分割,然后通过正射校正、辐射定标、大气校正对遥感影像进行预处理,最后通过多尺度分割实验分析各参数对尺度分割效果的影响.研究结果表明分割尺度为150、形状比例系数为0.7、紧致度...

| Abstract: | Aiming at the problem of information extraction of suspected illegal buildings in cities, a new algorithm
for extracting suspected illegal building information based on multi-scale segmentation method is proposed. Firstly,
the remote sensing image is segmented by setting multi-scale segmentation parameters, then is preprocessed by
orthorectification, radiometric calibration, and atmospheric correction. Finally, the influence of each parameter on
the scale segmentation effect is analyzed through multi-scale segmentation experiment. The results show that when
the segmentation scale is 150, the shape scale factor is 0.7, and the compactness scale factor is 0.3, the image
segmentation effect is the best. |
