Timber area segmentation method and system and storage medium

The invention provides a timber region segmentation method and system and a storage medium, and relates to the technical field of image segmentation. Constructing an original timber image data set through the acquired multiple timber images; performing image preprocessing on the original timber image data set, and dividing the timber image data set obtained by preprocessing into a training set and a test set according to a preset proportion; an improved Deeplabv3 + network is constructed based on the Deeplabv3 + network, and the improved Deeplabv3 + network comprises an improved Encoder and an improved Decoder decoder; the training set is imported into the improved Deeplabv3 + network for training, and a trained Deeplabv3 + network is obtained; and importing the test set into an improved Encoder in the trained Deeplabv3 + network for feature extraction, inputting a high-dimensional semantic feature map obtained by feature extraction into an improved Decoder decoder in the trained Deeplabv3 + network for fusio
