Road surface identification detection method and system and intelligent terminal

The invention discloses a road surface identification detection method and system and an intelligent terminal. The method comprises the following steps: acquiring an original image of a target area; inputting the original image into a pre-trained image segmentation model to obtain a segmented image of the road surface identifier output by the image segmentation model; wherein the image segmentation model is obtained by training an image sample and a segmented image corresponding to the sample based on a pre-constructed deep learning network; in a model training process, the deep learning network is used for extracting global information and local information of an image sample, learning edge information of a road surface identifier through an auxiliary learning branch, and realizing multi-scale information training by adopting a pyramid structure and residual connection. According to the method and the system provided by the invention, the accuracy of image segmentation in road surface identification detectio
