Abstract

The invention provides an out-of-city road extraction method and device based on a remote sensing image, and the method comprises the steps: obtaining GIS image information from a digital map, and generating mark data and training / testing data; constructing an initial road extraction network model based on a U-Net network; training the initial network model by using the mark data and the training / testing data to obtain a road extraction model with road recognition capability; and detecting a remote sensing image by using the road extraction model, and automatically extracting a road target. According to the invention, the improved U-Net network is constructed, so that the accuracy of urban road extraction by using the remote sensing image is improved.

Description

technical field [0001] The present application relates to the technical field of remote sensing information processing, in particular to remote sensing image processing technology, and in particular to a method and device for extracting road information outside a city based on remote sensing images. Background technique [0002] In recent years, my country's remote sensing technology has developed rapidly, and has been widely used in areas such as urban planning, resource mining, military affairs, water conservancy, pollution control, and emergency relief. For example, in wartime, some highway sections can be used as road airports, and mastering road airports is of great significance to air force operations. For another example, during emergency relief, especially in rural areas, finding a suitable road can improve the efficiency of search and rescue and reduce the waste of resources. [0003] Although my country's navigation and digital map technology has developed relativ...
