Multi-modal information fused lunar surface linear structure extraction method and system

The invention relates to the field of artificial intelligence, and particularly discloses a lunar surface linear structure extraction method and system fusing multi-modal information. Comprising the following steps: acquiring and processing a narrow-angle image of the lunar orbit surveyor to obtain high-precision digital orthoimage data DOM and corresponding high-precision digital elevation model data DEM, making labels to obtain DOM data labels and corresponding DEM labels, dividing the DOM data labels and the DEM labels into a training set, a test set and a verification set, and obtaining a training set, a test set and a verification set; constructing a segmentation network model fusing the multi-modal information, training by using the training set, the test set and the verification set to obtain a trained model, evaluating the trained model based on a preset training index, obtaining a final model if the evaluation is passed, and obtaining a segmentation result based on the final model. And carrying out l
