摘　　要：矿区道路作为矿区的主要运输通道,是采矿活动必需的组成要素。在空间结构上,矿区道路是其他要素的连接纽带,它们之间有着重要的空间拓扑关系———矿区通常由一条主要道路连接着开采面(矿硐)、选矿池、固体废弃物、工棚建筑和尾矿库等要素。通过对矿区道路的识别和提取,有助于建立地表采矿系统(surface mining system,SMS),对矿区进行遥感监测和自动遥感解译。利用高分辨率遥感图像,提出一种基于Canny边缘检测算子的矿区道路自动提取方法:首先利用Canny算子对遥感图像进行边缘检测,得到边缘信息;然后进行边缘匹配,判定道路边缘,从而对研究区内的道路进行定位和矢量化。利用该方法对某矿区道路进行提取实验的结果表明,该方法能快速提取矿区道路,具有较强的实用性。As the main transport corridors of the mine, the roads in the mining area are very important parts of the mining activities. Spatially, the roads are the connection links of the other elements in the mining area, and there are important topological relationships between them：The major road usually connects such elements as the mining surface area （or mine adit）, the processing pool, the solid waste mineral, the shed （or buildings ） and the tailings. The extraction and recognition of the mine road are helpful to building the surface mining system（ SMS）, making it easy to monitor the mining area and get automatic interpretation of remote sensing. In order to extract the mine road, the authors used high -resolution remote sensing image and proposed an approach based on Canny edge detection operator for automatic extraction of the road in the mining area in this paper. Firstly, the road edges were extracted by using the Canny detector. Furthermore, the edge matching method was used to determine the road edges, which resulted in the quantization and positioning of the road vector in the study area. The methods proposed in this paper were used to extract the road in the mining area successfully. The results show that the proposed method is of very strong practical applicability.
