| 摘 要： | 以水上桥梁的航空照片为基础，提出了一种对水上桥梁自动识别定位的方法，采用了基于假设检验的方法，主要包括根据水上桥梁的特点提出的先验知识，河流区域与非河流区域分割，桥面主边缘的检测定位以及对假设的检验。根据航空照片噪声干扰大的特点，采用了抗干扰能力强的Hough变换，并根据需要，对Hough进行了一些改进，本方法在试验中已经取得了很好的识别效果。

| Abstract: | Based on aerial picture of bridge across river,this method is proposed to automatically recognize and locate the bridges across river.Hypothesis detection is used in this method,including presentation of apriori knowledge segmentation between river's region and no-river's region,detection and location of main edges of bridge,and verification of the hypothesis.According to the feature of heavy noise in aerial picture,we use the Hough transformation,which can tolerate heavy noise,and adjust the Hough transformation.Good results have been obtained by the use of this method.[ |
