Tunnel crack detection method and system

The invention relates to the technical field of computer vision, and discloses a tunnel crack detection method and system.The method comprises the steps that a multi-head detection structure is introduced into a semantic segmentation model, and features of a plurality of hierarchical backbone networks are connected with different segmentation heads; wherein the multi-head detection structure can establish a plurality of branches in the backbone network, and each branch is connected with a different hierarchy of the backbone. According to the invention, the problems of low precision and the like in the prior art are solved. 本发明涉及计算机视觉技术领域，公开了一种隧道裂缝检测方法及系统，该方法在语义分割模型中引入多头检测结构，将多个层级骨干网络的特征与不同分割头相连接；其中，多头检测结构能在骨干网络中建立多个分支，每个分支与骨干的不同层级相连接。本发明解决了现有技术存在的精度较低等问题。
