The invention discloses a method for extracting road characteristics in a high-resolution image. A generator G capable of accurately identifying road characteristics is obtained by optimizing structures of a generator G, a discriminator D and a generative adversarial network V (D, G) and training parameters. In the training process, the difference between the generated sample Pg (x) and the real sample PData (x) is evaluated by using the Waserstein distance, so that the problem of gradient non-convergence of a loss function in the existing KL divergence or JS divergence evaluation can be effectively avoided. The road characteristics obtained through identification of the generator G obtained through the method are closer to the actual situation, and the accuracy is higher.
