摘要
利用线特征算子和多种线状地物跟踪方法建立了一种基于知识的航空影像中道路半自动提取方法。该算法计算量小 ,判断速度快 ,准确率较高 ,并且有较好的适应性。试验表明这是一种良好的道路提取方法。
A synthesized several linear feature extraction method based knowledge in aerial photo is proposed in this paper. This method adopt different methods according to different condition. Experiments evince this method is a good linear feature extraction method.
