This creation department is about a three-dimensional modeling device for tunnel stereo image, especially a digital camera with infrared scanner for three-dimensional deformation measurement and leakage detection of tunnels, thereby achieving the safety of monitoring tunnel safety as the primary author.

According to the three-dimensional size of the tunnel, it can be used as the reference data for the deformation of the tunnel. The deformation of the tunnel can be analyzed by comparing the three-dimensional dimensions of the tunnel obtained in different periods. The deformation of the tunnel is mainly caused by the change of external force. The source of these external forces mainly comes from loose earth pressure, sudden collapse, lateral pressure, expansive soil pressure, insufficient bearing capacity and water pressure. Tunnel deformation behavior. The damage caused by the aforementioned influencing factors to the tunnel lining can be used to assess the safety level of the completed tunnel. The deformation value of the tunnel lining is one of the important factors for safety assessment. When the deformation rate of the lining is greater than a certain value in the project, it is necessary to focus on monitoring, or it must be handled as soon as possible. In other words, the monitoring of lining deformation is an important item for tunnel safety inspection operations.

However, the tunnel is a long and narrow space, generally adopting 1. traverse measurement or 2. cross-section measurement. Because the method of traditional section measurement has a limited number of samples, and the sampling point is still dependent on empirical judgment. Often the quality of the construction is measured and the quality of the personnel is uncertain and cannot be mastered. Moreover, if the records of the distribution and structure of geological rock layers during construction are not detailed enough, it will be inconvenient for future maintenance and reconstruction.

Therefore, the creator has a stereoscopic image measuring method and device for tunnel deformation in the previous research and development application No. I526670, and a stereoscopic image measuring device of the publication No. M506956, which mainly comprises: an image capturing group, A camera is correspondingly mounted on a base that can rotate in a vertical direction and rotate in a horizontal direction; a pattern projection group is disposed on one side of the image capturing group, and is provided with a characteristic projection component, and a light source is disposed in the feature projection component The target projection component is projected onto the object to be measured by the light source; and a control group is a corresponding connection image capturing group for receiving the image capturing component to capture the image data of the feature projection component on the object to be measured, and The result of displaying the image measurement result by integration processing.

However, in addition to the deformation problem, the tunnel has the problem of wall leakage. Because the tunnel is used for a long time, there are often cracks or repair joints, etc., and the rain and rain in the mountain forest are more serious, so the tunnel is obviously Leakage phenomenon, this is one of the problems that need to be solved.

Various problems. However, infrared thermal image detection technology uses infrared light (energy) radiated from the surface temperature of the object above absolute zero to calculate the surface temperature distribution of the object. Therefore, the creator applies its technology to tunnel measurement and provides a three-dimensional image of the tunnel. Modeling devices for the purpose of achieving better practical value.
