改进YOLO模型的岩体节理特征快速检测与应用OA

In view of the problems that existing monitoring methods for rock mass joints mainly rely on manual identification,with low detection efficiency and strong subjectivity,a detection and segmentation method for rock mass joints was proposed in this paper.The model improved the YOLOv8 algorithm by introducing the multi-scale feature module(MSBlock)and channel prior convolutional attention(CPCA)mechanism to enhance the image recognition accuracy of the existing YOLOv8 network model.By introducing the MSBlock algorithm,features at different scales and levels were fused,which could both capture the fine local details in the image and recognize the image features macroscopically.By introducing the CPCA mechanism,the attention distribution was adaptively adjusted according to the current image features,enabling the network to more flexibly deal with different targets.A total of 4 057 images collected from the AM Highway Project in Equatorial Guinea were trained and recognized.The results indicate that the performance evaluation indicators of the optimized algorithm,including Box(P),Box(R),Mask(P),Mask(R),rIOU,and CDICE,reach 89.4%,87.1%,61.6%,58.9%,92.8%,and 86.8%,respectively.Compared with the original model,these indicators increase by 4.6 percentage points,9.5 percentage points,8.5 percentage points,12.4 percentage points,17.5 percentage points,and 1.1 percentage points,respectively.This multi-scale feature fusion algorithm is more accurate and efficient when handling complex images and has better adaptability and robustness.
