Mobile device and method for projecting and displaying lining disease information on the outer surface of tunnel lining

Abstract

The invention relates to a mobile device and method for projecting and displaying lining disease information on the outer surface of a tunnel lining, which includes a vehicle body, a light source system, a projection unit installed on the vehicle body, and a control system; the control system includes a positioning unit, a distance measuring Unit, system storage server and communication unit; the projection surface of the projection unit is the outer surface of the tunnel lining, and the control system retrieves the disease information data from the disease information data package stored in the cloud server, and downloads it to the system storage server in the form of an image , the image is projected onto the outer surface of the lining of the tunnel through the projection unit. The present invention can efficiently and accurately visualize the disease information obtained through detection work during the operation period of the tunnel, accurately locate the position of the disease on the outer surface of the tunnel lining, and visually display it through adaptive projection, helping to grasp the safety status of the tunnel structure in a comprehensive and timely manner. Ensure the smooth development of inspection and repair work.

Description

technical field [0001] The invention relates to the field of tunnel detection, in particular to a mobile device and method for projecting and displaying lining disease information on the outer surface of a tunnel lining. Background technique [0002] At present, the number of highway and railway tunnels is increasing, which greatly improves the convenience of people's travel. However, due to the continuous changes in the external environment and geological conditions, as well as other aspects such as design, construction, management and construction of surrounding buildings, the tunnel is in operation during the operation period. , lining diseases such as cracks, leakage, large deformation, and voids between the supporting structure and the surrounding rock often occur, which seriously threaten the normal and safe use of the tunnel. For these diseases that exist behind the tunnel lining, tools such as geological radar and tunnel inspection vehicles can be used to detect and ...

Problems solved by technology

Its application is limited to subway trains and subway tunnels. The main purpose is to expand the advertising space. It cannot be associated with the lining disease information obtained through detection. It is used for the detection of tunnels during various operation periods.

[0005] Restricted to the fact that most of the outer surface of the tunnel lining is a non-planar area, when the lining disease information and images are projected onto the non-planar lining area or cannot be projected due to limited conditions, the geometric shape of the directly projected disease information and images will be deformed. Cause geometric distortion, reduce the accuracy and efficiency of the entire tunnel lining disease detection and repair
