A scene segmentation method and device, and a storage medium. In the present disclosure, an image to be identified is inputted into a deep neural network, depthwise separable convolution is performed on the image by using a down-sampling module to obtain a first characteristic image smaller than the image in size, atrous convolution is performed on the first characteristic image by using an atrous spatial pyramid pooling module to obtain second characteristic images with different scales, and depthwise separable convolution is performed on the second characteristic images with different scales by using an up-sampling module to obtain a third characteristic image with the same size as the image, and pixels in the third characteristic image are classified by using a classification module to obtain a scene segmentation result of the image.
