Problems solved by technology

Moreover, the current on-site palm face sketching is mainly completed by naked eye observation, manual sketching, and paper records. The work efficiency is low, the analysis accuracy is poor, the amount of information is limited, and the feedback time is long.
[0004] At present, the techniques for face analysis of images generally use traditional image processing methods such as image preprocessing and filtering binarization to extract joint features. There are many misunderstandings and omissions, and the effect is not good.
And there is no combined analysis of 3D geometric information and 2D image information, making full use of image information for combined recognition

Abstract

The invention relates to a tunnel face analysis method based on image data, and the method comprises the steps of carrying out the quality judgment of a collected face image, and carrying out the three-dimensional reconstruction of a qualified face image, and obtaining a three-dimensional point cloud model; acquiring a tunnel face area and two-dimensional joint data in the two-dimensional image; extracting structural plane features of the image by using a neural network model, and processing the structural plane feature image to extract structural plane line data; and carrying out combined analysis on the structural plane projected to the two-dimensional image by the three-dimensional analysis and the structure extracted by the neural network, obtaining all identified tunnel face joints byclustering and grouping, and drawing a tunnel face sketch map by utilizing a computer. The invention has the advantages that geological analysis is carried out based on the geometric structure of thetunnel face, and meanwhile ultra-short-distance prediction is carried out on the front tunnel face. By combining three-dimensional geological information and by means of deep learning and image recognition technologies, a structural plane is identified, and sketch difficulty and operation time are reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel geological prospecting, in particular to a tunnel face analysis method based on image data. Background technique [0002] "Tunnel excavation, geology first", the primary task of tunnel safety control is to quickly, accurately, comprehensively and timely grasp the tunnel geology. Relevant regulations require that during the tunnel construction process, geological survey, advanced geological forecast and geological sketch of the tunnel face will be carried out in sequence until the tunnel is penetrated. However, due to the limitation of survey technology and funds, the geological survey work is relatively rough, and geological omissions occur from time to time, especially in long tunnels. The tunnel face geological information revealed by tunnel excavation is the most accurate and intuitive, which can be used for comprehensive nowcasting of fault fracture zones, large-scale landslides, and coal and ...
