Problems solved by technology

[0003] The geological catalog of the face is mainly to collect and analyze the important geological structure information in the face of the tunnel, mainly through the naked eye observation, and then manually describe the geological characteristics. The light interference in the construction cave is large, and the geometric accuracy of the catalog is low, the intuitiveness is poor, the information feedback is slow, and the amount of information is limited. At the same time, it is not conducive to the analysis and application of the catalog results

Embodiment 1

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings. The tunnel face geological multi-dimensional digital record identification method of the present invention, such as figure 1 Shown: specifically include the following steps,

[0030] S1. Determine the target object, and determine the installation positions of the camera device, infrared thermometer and laser rangefinder. In order to improve the detection accuracy, the camera device uses a digital camera with higher effective pixels and better image quality. The digital camera model used is Canon EOS45OD, which is a SLR camera. The maximum resolution of the camera is 4272x2848, that is, 12.2 million pixels. It is a German Zeiss zoom lens with a focal length of 18-55mm. The camera can focus automatically or manually. Determine the installation location of the equipment, fix the camera device on the tripod, and adjust the tripod head to the level to keep it stable. The ...

Embodiment 2

[0059] The tunnel face geological multi-dimensional digital record recognition system of the present invention, such as figure 2 , shown in 3 and 4, including an image acquisition device, which collects geological image data of the tunnel face; an image processing device, which analyzes the lithology of the face according to the collected geological image data of the tunnel face, and obtains the tunnel face Face structural surface features and rock mass texture features; 3D geological structure model reconstruction device, reconstruct the 3D geological structure model of the face structural surface features and rock mass texture features, perform geological analysis and geological slices on the working face to generate geological sections picture.

Abstract

The invention discloses a tunnel face geology multi-dimensional digitized record recognition method. The method comprises the steps that a target object is determined, installation positions of a video shooting device, an infrared thermometer and a laser ranger finder are determined, the target object is divided into four parts which are imaged respectively, images are preprocessed, the preprocessed images are subjected to structural information extraction and analysis, and structural surface features and rock mass texture features are obtained, a three-dimensional geological structure model is reestablished, geology is predicted, fracture surface and rock stratum joint images of adjacent faces are obtained from face images in the three-dimensional geological structure model, every two adjacent rock stratum joint boundaries share the same structural surface, a virtual section cutting plane at any angle crosses with the boundary of the corresponding structural surface, and a geology longitudinal plan is obtained. The three instruments are adopted to quickly, efficiently and comprehensively collect the conditions of the faces, the collecting mode that the images of partitions are collected respectively and then synthesized into images is adopted for the tunnel face images, the image quality of the collected images can be improved, image processing in a later stage is easy, and the accuracy of the images is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a multi-dimensional digital record recognition method and system for tunnel face geology. Background technique [0002] At present, the geological conditions of tunnel engineering directly affect the method, safety, quality and progress of tunnel construction. Therefore, the geological catalog of the tunnel face is an important basic work for tunnel construction, providing important basic data for geological prediction and tunnel construction. [0003] The geological record of the face is mainly to collect and analyze the important geological structure information in the face of the tunnel, mainly through the naked eye observation, and then manually describe the geological characteristics. The light interference in the construction cave is large, and the geometric accuracy of the catalog is low, the intuitiveness is poor, the information feedback is slow, and the amoun...
