Abstract

The invention provides a data acquisition method and a tunnel inspection car, and belongs to the technical field of imaging detection. The data acquisition method is applied to the tunnel inspection car, and the tunnel inspection car comprises a control device and at least one group of imaging devices, wherein the at least one group of imaging devices are electrically connected with the control device. The method comprises the following steps: controlling the at least one group of imaging devices to reciprocate along a preset trajectory by the controller; and when the moving direction of the imaging devices is opposite to the direction of travel of the tunnel inspection car, and the difference between the motion velocity of the imaging devices and the motion speed of the tunnel inspection car is within a preset range, controlling the imaging devices to acquire image data of a tunnel inner wall by the control device. The scheme of the invention can effectively avoid the motion blur generated by the acquired images of the tunnel inner wall, so as to improve the image acquisition efficiency of the tunnel inspection car and meanwhile improve the quality of the acquired images.

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...
