Abstract

The invention discloses a tunnel detection method and device based on an unmanned aerial vehicle. The method includes: receiving a video image of a tunnel obtained by an unmanned aerial vehicle; performing preprocessing and standardization processing on the video image; The processed video image is input into a trained three-dimensional convolutional neural network (3D-CNN) model, and the three-dimensional convolutional neural network model outputs a tunnel defect detection result according to the video image. The invention obtains the video image of the tunnel through the drone, and inputs the video image into the trained three-dimensional convolutional neural network model, which can better capture the spatial and temporal characteristics of the video, and quickly output the tunnel defect detection result , improve the identification rate, detection frequency and processing speed of tunnel diseases, and reduce the degree of manual dependence.

Description

Technical field [0001] The present invention relates to the field of tunneling detection, and more particularly to a drone-based tunnel detection method and apparatus. Background technique [0002] With the acceleration of urbanization, urban subways have developed rapidly, and the underground infrastructure of construction is also more and more. In recent years, tunnel safety problems have been frequent, such as tunnel cracks, leakage, settling, lining, causing serious casualties and huge economic losses, so tunnel safety is a key issue during tunnel operations. [0003] Traditional artificial inspections and closed-circuit television systems discovering that problems will lead to serious consequences, and tunnel disease inspections should be carried out in a manner in combination with information. With the continuous development of drone technology, the field of drone applications is increasingly wide. It has been applied in aerial photography, agriculture, plant protection, ex...
