This invention discloses a real-time building damage monitoring method for UAVs based on vision-IMU fusion. It utilizes an improved YOLOv11 to detect crack regions in monocular images, enhances the boundary and texture features of small cracks using SCConv and AFPN, and employs an MPDIoU bounding box regression strategy to improve positioning accuracy in complex backgrounds. To suppress image drift caused by flight jitter, an adaptive threshold stabilization module based on Alike features and Lucas-Kanade optical flow is constructed to achieve stable alignment of image sequences. Addressing the monocular vision scale drift problem, a loosely coupled vision-IMU fusion algorithm is employed. Through extended Kalman filtering combined with zero-velocity updates and gyroscope bias correction, high-precision estimation of the camera's six-DOF pose is achieved. Based on this, the three-dimensional geometric information of the cracks is reconstructed, enabling accurate quantification of crack length and width. This algorithm maintains stable performance even under complex environmental conditions, providing crucial technical support for UAV inspection and intelligent operation and maintenance of urban infrastructure.
