Abstract

The invention discloses a tunnel detection method and device based on an unmanned aerial vehicle. The method comprises the following steps: receiving a video image of a tunnel acquired by the unmanned aerial vehicle; performing preprocessing and standardization processing on the video image; and inputting the preprocessed and standardized video image into a trained three-dimensional convolutional neural network (3D-CNN) model, wherein the three-dimensional convolutional neural network model outputs a tunnel disease detection result according to the video image. According to the method, the video image of the tunnel is acquired through the unmanned aerial vehicle, and the video image is input into the trained three-dimensional convolutional neural network model, so that the space and time features in the video can be better captured, the tunnel disease detection result is quickly output, the recognition rate, the detection frequency and the processing speed of the tunnel disease are improved, and the manual dependence degree is reduced.

Description

technical field

[0001] The invention relates to the technical field of tunnel detection, in particular to a tunnel detection method and device based on an unmanned aerial vehicle. Background technique

[0002] With the acceleration of urbanization, urban subways have developed rapidly, and more and more underground infrastructures have been built accordingly. In recent years, tunnel safety problems have occurred frequently, such as tunnel cracks, water leakage, settlement, lining peeling, falling blocks, etc., causing serious casualties and huge economic losses. Therefore, tunnel safety is a key issue during tunnel operation.

[0003] Traditional manual inspection and closed-circuit television system will not find problems in time, which will lead to serious consequences. Tunnel disease inspection should be carried out by combining manual and information means. With the continuous development of UAV technology, UAV application fields are becoming more and more extensive, an...
