The invention relates to the technical field of rock mass structural plane identification, in particular to a tunnel rock mass main structural plane identification method and device based on image identification, and the method comprises the steps: obtaining an excavation face image, carrying out the slicing segmentation, carrying out the identification based on a pre-trained rock mass structural plane trace identification model, obtaining an image with a prediction trace, and carrying out the prediction of the prediction trace. And carrying out clustering fitting processing to obtain a structural plane trace. According to the method, the requirement for the original image in the recognition process can be effectively reduced, the capture precision of the prediction trace can be improved, overfitting is avoided, noise points on the prediction trace are greatly eliminated, the obtained structural plane trace can be closer to the real structural plane trace, and therefore the accuracy of trace judgment is impro
