Abstract

The invention provides a data collection method and a tunnel inspection vehicle, which belong to the technical field of imaging inspection. The data acquisition method is applied to a tunnel inspection vehicle. The tunnel inspection vehicle includes a control device and at least one group of imaging devices, and the at least one group of imaging devices are all electrically connected to the control device. The method includes: the control device controls at least one group of imaging devices to reciprocate along a preset trajectory; when the moving direction of the imaging device is opposite to the traveling direction of the tunnel inspection vehicle, and When the difference between them is within a preset range, the control device controls the imaging device to collect image data of the inner wall of the tunnel. The solution can effectively avoid motion blur in the collected image of the inner wall of the tunnel, thereby improving the image collection efficiency of the tunnel inspection vehicle and improving the quality of the collected image.

Description

technical field [0001] The invention relates to the technical field of imaging detection, in particular to a data acquisition method and a tunnel inspection vehicle. Background technique [0002] There are a large number of tunnel projects in railways, highways, subways and other transportation projects. After the tunnels are put into operation, quality problems such as leakage, lining cracks, lining deformation, and road surface cracks usually occur, which bring safety hazards to vehicle traffic. Therefore, during the operation period of the tunnel, it is necessary to regularly detect and evaluate the health status of the tunnel. Tunnel health issues are included in relevant regulations for road, railway, and subway maintenance. [0003] The existing method is to install an optical camera for collecting tunnel images on the detection vehicle. When it reaches the image collection point, the detection vehicle stops and collects tunnel images through the optical camera, there...
