Summary of road extraction methods for remote sensing images

Road information plays an important role in modern society. It is of great scientific significance to study the road extraction method of remote sensing image. This paper reviews the development process of road extraction method, and divides the existing road extraction methods into three categories： based on pixel, object-oriented and deep learning according to the realization form. It is used as a clue to analyze and compare the scope of application of various methods with advantages and disadvantages. Design experiments, with a number of high-resolution satellite remote sensing images as the experimental object, verify the comparison of various types of typical road extraction method of the actual performance. The experimental results show that the method of road extraction based on deep learning is the best. Finally, based on the theory of popular remote sensing data and artificial intelligence, the development trend of road extraction method of remote sensing image is prospected.
