| 摘 要： | 通过对遥感影像上防波堤的空间关系特征和其他特征的分析,设计了一种基于水边线的遥感影像防波堤提取方法。该方法首先对海岸带影像进行水边线提取;然后,将提取的水边线作为海陆分界线,进行海陆分割,得到海陆二值图;最后根据遥感影像上防波堤的空间关系特征和其他特征将防波堤从水边线中分割出来,并剔除伪防波堤的干扰。实验结果表明,该方法能够实现防波堤的自动准确提取,并且提取速度快、稳定性好。

| Abstract: | The characteristics of spatial relations and context features of breakwater on remote sensing image are analyzed,a breakwater extraction method based on waterline is proposed in this paper.Firstly,waterline is extracted from coastal zone image.Secondly,binary image,which regard the waterline as land and sea boundary line,is obtained based on land and sea segmentation.Finally,breakwater is split out from waterline based on spatial relations feature and other features,and then remove false breakwater.The experimental results show that this method can automatically,efficiently ,accurately and steadily extract breakwater. |
