Problems solved by technology

[0004] The inventor found that, in the field construction, on the one hand, it is basically impossible to draw the structural surface of the tunnel face manually, and the mapping of the tunnel face itself is to evaluate the unknown rock mass within the range of 30-50m ahead
Moreover, the detection of the face is cumbersome, and the extraction of geological information is difficult, which is not conducive to the construction progress of the construction party.
[0005] On the other hand, the currently used tunnel surface rendering method is greatly disturbed by light sources, dust and other factors, and the image acquisition equipment cannot accurately and clearly capture the panoramic image of the structural surface, resulting in measurement errors and cannot be used for comprehensive geological surveys. Evaluation and analysis, and the processing of detection data is relatively simple, not intuitive enough

Description

technical field [0001] The disclosure belongs to the technical field of tunnel face geological identification, and in particular relates to a multi-spectral camera system for a rock drilling jumbo and an intelligent identification method for surrounding rocks. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, in the construction of highways and railways in our country, tunnel construction is an inevitable problem. The face of the tunnel is the working face that is constantly advancing during the excavation of the tunnel. It contains a lot of geological structure information and is also the most direct source of information for engineers to judge possible disasters ahead. [0004] The inventors found that, in on-site construction, on the one hand, it is basically impossible to draw the structural surface of the tunnel face manua...
