Embodiment Construction

[0024] like Figure 1-4 As shown, the tunnel full-section three-dimensional laser monitoring and measuring method of the present invention includes the following steps:

[0025] Step 1: Arrange black and white reflective cross targets in the tunnel to be measured as required;

[0026] Step 2: Determine whether to use one-station scanning or multi-station scanning according to the length of the tunnel monitoring (the specific determination method can be accurately determined or known by those skilled in the art under the condition of the prior art, and belongs to the prior art);

[0027] Step 3: Set up a FARO-III 3D laser scanner at an appropriate location, and use the phase interference method 3D laser scanning system to scan the entire section of the tunnel;

[0028] Step 4: Wait for the scan to be completed and then import the data into the computer;

[0029] Step 5: Using 3D data processing software, the scanned point cloud data is registered to generate a 3D model;

[0...

Abstract

The invention relates to a method for monitoring and measuring a full section of a tunnel through three-dimensional laser, and belongs to the field of tunnel engineering construction monitoring. The method comprises the following steps of: arranging target points in a tunnel to be measured according to a requirement; determining whether to adopt one-station scan or multi-station scan according to the monitoring length of the tunnel; erecting an instrument at a proper position and scanning the full section of the tunnel; after the scan is finished, importing data into a computer; registering point cloud data acquired through the scan to generate a three-dimensional model by applying three-dimensional data processing software; and generating a comparison model by combining a previous three-dimensional model for the same tunnel at different time, and selecting a specific section and characteristic points to generate a variation analysis chart and a variation analysis sheet for a corresponding position. By the method, the full section of the tunnel is monitored in real time, the speed and accuracy of monitoring and measuring work are improved, manpower and material resources are saved, the speed and quality for monitoring and measuring the tunnel are improved, and reliable guarantee is provided for tunnel engineering construction.

Description

technical field [0001] The invention relates to a measurement method, in particular to a tunnel full-section three-dimensional laser monitoring and measurement method, which is applicable to the monitoring and measurement of clearance changes in tunnel construction, and belongs to the field of tunnel engineering construction monitoring. Background technique [0002] my country is a mountainous country, and tunnels account for a large proportion of the construction of railways and highways in mountainous areas of our country. At present, more and more new Austrian methods are used in tunnel engineering in my country. The main feature of building tunnels with new Austrian methods is to monitor the dynamics of the tunnel surrounding rock after excavation through many measurement methods, and use them to guide tunnel support. Design and construction of protective structures. As an important part of NATM tunnel construction, the accuracy and timeliness of tunnel monitoring and me...
