Embodiment Construction
[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0052] The invention provides a tunnel abnormal state monitoring method based on an unmanned aerial vehicle device, which realizes the autonomous monitoring of the environment in the tunnel by an unmanned aerial vehicle.
[0053] The tunnel abnormal state monitoring method mainly includes: using a high-definition camera to photograph the environment in the tunnel, including rail status, obstacles in the tunnel, and tunnel cracks; Focus on shooting in abnormal environments, and customize the drone's autonomous conflict resolution strategy after encountering obstacles. Firstly, the high-brightness supplementary light source is used to solve the problem of no light or very dark light in the tunnel. At the same time, the combination of optical flow sensor and three-axis gimbal keeps the high-definition camera stable, so as to realize the normal shooting of the en...
