Abstract
The application discloses a tunnel face joint information calculation method based on YOLOv8-seg, which comprises the following steps: a face joint data set is established, and data in the data set is labeled; the labeled joint data set is divided into a training set, a test set and a verification set, a YOLOv8-seg model is optimized, the joint data set is input into the optimized model for training, and a joint photo with a mask marked area is output after the training is completed; the joint information of the mask area is further processed according to the photo output by the model, the pixel height of the joint is calculated, and skeletonization is performed to extract to a single-pixel width; and finally, the actual height and length information of the joint are calculated according to the processing result of the previous step.
