Problems solved by technology

However, in the process of photography and laser measurement, it is still necessary to manually set up cameras, scanners and other devices in front of the tunnel excavation to collect images of the tunnel face, and the safety of personnel is still not guaranteed.
In addition, due to the harsh environment of the tunnel construction site, such as poor light and large dust, and the tight construction process of the tunnel face, it is necessary to determine the position and time of the face image shooting in a short time, and then obtain high-quality palm Subface images are more difficult

Embodiment 1

[0038] see Figure 1~Figure 3 , a face intelligent perception system based on a rock drilling jumbo, including a right camera 2 and a right pan / tilt 3, a left camera 4, a left pan / tilt 5 and a computer 6; the right pan / tilt 3 and the left pan / tilt 5 are respectively installed on Both sides of the cab 7 of the trolley 8; the left camera 4 is arranged on the left cloud platform 5; the right camera 2 is arranged on the right cloud platform 3, and a software system is installed in the computer 6, and the computer 6 can communicate with the camera and the cloud platform; The left camera 4 and the right camera 2 are used to collect image information on the face 1 .

[0039] Such as figure 1 As shown, the operator in the cab 7 of the trolley 8 adjusts the rotation angles of the right pan-tilt 3 and the left pan-tilt 5 through the software system of the computer 6 at any time, and controls the right camera 2 and the left camera 4 to take pictures. When the face 1 image is taken, it ...

Abstract

The present invention provides an intelligent analysis method for face face based on a rock drilling jumbo, which adopts an intelligent sensing system for the face face. The intelligent sensing system includes an image acquisition component and a computer; two sets of image acquisition components are installed on the trolley The two sides of the cab; the image acquisition components include the pan-tilt and the camera; through the software system in the computer, the computer can communicate with the camera and the pan-tilt. The intelligent analysis method includes the following steps: calibrate the camera to obtain camera parameters; take images of the left and right faces of the face and perform 3D reconstruction; obtain point cloud data and triangular meshes of the face; Average inclination and average inclination of structural planes. The invention integrates the camera and the pan / tilt on the trolley, and the operator can adjust the shooting angle in the cab, and shoot the tunnel surface in real time, which improves the construction efficiency and safety; the three-dimensional reconstruction of the tunnel surface is extracted Occurrence information reduces personnel measurement errors and improves the accuracy of occurrence calculations.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an intelligent analysis method for a tunnel face based on a rock drilling jumbo. Background technique [0002] During the construction of the tunnel face, if the rock mass geological conditions of the face can be grasped based on the information contained in the tunnel face, it can provide an important basis for evaluating the stability of the surrounding rock and determining the tunnel support scheme and construction technology. [0003] At present, in the process of domestic tunnel construction, geological surveyors still use traditional tools such as tape measure, geological compass, and vernier caliper to measure geological information on site. In the process of geological description, surveyors are faced with many problems, such as the long time for geological information collection, which makes it impossible to meet the needs of rapid construction of the project...
