基于知识的遥感图像中桥梁识别方法

Method of Bridge Recognition in Sensing Image Based on Knowledge

利用桥梁、河流和陆地各自在遥感图像中的信息特征,提出了一种基于知识的遥感图像中桥梁识别方法,通过对桥梁知识的理解,来指导图像的处理和分析。首先,对图像进行分割,提取边缘;然后利用桥梁线和河岸的不同特征,在图像中去除河岸线,保留桥梁线。实验证明,该识别方法比较简单快速,并且取得了较好的识别效果。

Making using of the information and the features of bridge, river and land in the sensing image, a method of bridge recognition in the sensing image based on the knowledge is presented. Through comprehending the bridge knowledge, the image processing and analyzing is directed here. First, the image is segmented and its edge is got. Second, using the difference between the bridge line and the river bank, the river bank line is removed and the bridge line is received. The test proves that the recognition method in this paper is simply and quickly realized and can have a better effect.
