[0002] As a crucial transportation infrastructure, tunnel engineering requires strict monitoring of structural safety during construction and operation. The stability of tunnel structures is influenced by various factors, such as construction disturbance, ground stress, and groundwater, which can lead to displacement or deformation of the primary support and secondary lining structures. Therefore, real-time monitoring of tunnel displacement is essential for assessing structural safety, providing early warning of geological hazards, and guiding maintenance work. Traditional monitoring methods rely on manual labor and periodic measurements, which suffer from drawbacks such as poor continuity, low accuracy, and data lag.

[0003] With advancements in computer vision, image processing, sensor technology, and wireless communication, tunnel visualization monitoring technology has emerged. This technology utilizes high-definition cameras and other equipment to capture real-time images of tunnels, identifies defects such as cracks and settlement through image processing, and combines GPS to achieve 3D modeling and dynamic monitoring. However, tunnel visualization monitoring technology still faces challenges such as the harsh tunnel environment, complex data processing, system stability, and data transmission.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model discloses a high-definition tunnel displacement monitoring system, including: an observation instrument 3 and a post-processing device; wherein, the observation instrument 3 and the post-processing device are communicatively connected.

[0022] Furthermore, such as Figure 2 As shown, the observation instrument 3 includes an infrared high-definition camera module 4, a GPS module 5, and a WiFi signal module 6 connected in sequence.

[0023] Furthermore, the infrared high-definition camera module 4 uses Hikvision DS-2CD2043G0-I, and the GPS module uses u-blox ZED-F9P;

[0024] Infrared high-definition camera module 4 captures high-definition images inside the tunnel; GPS module 5 determines the coordinate information of the location of observation instrument 3 and converts the captured image observation points into a coordinate system in the form of (x,y,z); WiFi signal module 6 transmits the image information and coordinate information to the post-processing equipment.

[0025] Furthermore, the post-processing equipment receives the image information and coordinate information output by the observation instrument 3, stitches the image information into a whole photo, and obtains the (x,y,z) coordinates of all observation points 7. Through the reference point 1, the (x,y,z) coordinates are converted into standard coordinates.

[0026] Specifically, the post-processing equipment can also record the images and coordinate information taken by each infrared high-definition camera in the infrared high-definition camera module 4 at regular intervals (such as 1 hour). By analyzing the coordinate changes, the displacement of the observation point and the pouring conditions, cracks and other issues in the tunnel 2 can be obtained, thus achieving the purpose of continuous monitoring.

[0027] Furthermore, the observation marker 7 is a marker pre-installed in tunnel 2 that converts the image information output by the observation instrument 3 into pixel positions.

[0028] The working principle of this utility model is as follows: First, a reference point 1 is established outside tunnel 2 from a designated leveling point, and an observation marker 7 is set up there. Then, multiple observation instruments 3 are arranged at certain intervals (e.g., 20m or one arch) inside tunnel 2, and another observation instrument 3 is also set up next to the reference point 1. Each observation instrument 3 captures high-definition images of the tunnel through an infrared high-definition camera module 4, obtains the corresponding position through a GPS module 5, converts it into a (x,y,z) coordinate system, and then transmits the coordinate information to the post-processing device through a WiFi signal module 6. The post-processing device stitches the images into a complete photograph and obtains the (x,y,z) coordinates of all observation markers 7. The (x,y,z) coordinates are converted into standard coordinates through the reference point 1. The observation instrument 3 takes a photograph at regular intervals (e.g., 1 hour) and repeats the above process. The post-processing device analyzes the displacement of the observation point by comparing the coordinate information at different time points.

[0029] The specific implementation process of this utility model is as follows: (e.g.) Figure 1 As shown, firstly, in order to ensure the accuracy of the construction and monitoring of tunnel 2, benchmark point 1 is precisely extended to the outside of tunnel 2 and an observation mark 7 is set for it. This point will also serve as the benchmark point for subsequent work.

[0030] Inside tunnel 2, multiple observation instruments 3 are arranged at pre-set intervals (in this invention, one arch). Simultaneously, an observation instrument 3 is also set up next to the reference point 1 to ensure that all observation instruments 3 remain synchronized and calibrated. The infrared high-definition camera module 4 included in each observation instrument 3 possesses high clarity and infrared night vision capabilities, ensuring clear images can be captured even in low-light conditions within tunnel 2.

[0031] Each observation instrument, via its built-in GPS module 5, can accurately determine its spatial position, allowing its captured images 8 to be converted into a (x, y, z) coordinate system. This enables the digitization of the spatial location within the tunnel, facilitating subsequent data analysis and processing.

[0032] like Figure 3 and Figure 4 As shown, the infrared high-definition camera module 4 built into the tunnel internal observation instrument 3 captures images of the interior of tunnel 2 from all angles. It captures the pixel positions of the observation marker 7 in image 8 and converts them into digital information. Next, the WiFi signal module 6 in the observation instrument 3 transmits the coordinate information of images 8 captured by each observation instrument to the post-processing equipment in real time. The post-processing equipment is responsible for receiving, storing, and processing this coordinate information, providing data support for subsequent tunnel monitoring and analysis. As tunnel 2 is excavated, the distance to the tunnel entrance increases, and the signal inside the tunnel weakens. At this point, the WiFi signal module 6 can transmit the relevant information of image 8 from the inside out through the observation instruments until it reaches the post-processing equipment. After receiving this information, the post-processing equipment stitches together the images captured by each infrared high-definition camera to form a complete photograph of the interior of tunnel 2.

[0033] After the photos are stitched together, the post-processing equipment uses image processing technology to analyze and extract the (x, y, z) coordinates of all observation points 7 in the photos. To convert this coordinate information into more practically meaningful standard coordinates, reference point 1 will be used. Using the coordinate information of reference point 1, the (x, y, z) coordinates inside tunnel 2 can be converted into coordinate values ​​in the standard coordinate system. Then, the deformation and displacement inside tunnel 2 can be determined.

[0034] Finally, to monitor the tunnel's deformation and displacement in real time, the observation instrument 3 takes an image 8 at regular intervals (1 hour in this invention), and repeats the above process. The post-processing equipment compares and analyzes the coordinate information at different time points to determine the displacement of the observation points. This data will provide important reference for the safe construction and monitoring of the tunnel.

[0035] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
