Embodiment Construction
[0061] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0062] On the one hand, this application provides a network model that can jointly implement semantic segmentation and depth estimation, such as figure 1 As shown, before the image is input into the model, the image is initially extracted through 3*3 standard convolution to obtain the input image. The network model in this embodiment includes:
[0063] The feature sharing module is configured to perform feature extraction on the input image through a convolutional neural network to obtain shared features. Specifically, the feature sharing module adopts an encoding-decoding ((encoder-decoder)) structure, including an encoding unit and a decoding unit. The output of the encoding unit is used as the input of the decoding unit. The encoding unit performs feature encoding and down-sampling processing on the input image, and decodes The unit performs upsampling a...
