Problems solved by technology

[0004] For the construction of tunnels, especially the construction of long tunnels, the acquisition and analysis of the development characteristics of cracks or joints in the surrounding rock mainly rely on methods such as on-site observation by testers, manual sketches, and test statistics. These traditional measurement methods are heavy workload, time-consuming, and serious Affects work efficiency and cannot adapt to current tunneling requirements
In recent years, some people have also adopted camera shooting methods to obtain images of surrounding rocks. However, the surrounding rocks at different heights in the tunnel restrict the testers from taking close-up shots, resulting in blurred images; limited by the imaging area of ​​a single camera, the photographed surrounding rock cracks or Incomplete joint imaging makes the surveying data inaccurate

Abstract

The invention provides a panoramic imaging system and method based on a vehicle-mounted drilling and blasting tunnel. The panoramic imaging system comprises a moving vehicle which is used for carrying out the mobile measurement, and obtaining the position of a test point of surrounding rock imaging; an image acquisition system which comprises a spherical transparent protective shell and a plurality of cameras arranged in the spherical transparent protective shell, and is used for acquiring surrounding rock images of corresponding test points in different directions; a moving mechanism which is arranged on a moving vehicle, bears the image acquisition system and drives the image acquisition system to move to a designated position of the end face of the tunnel; a data transmission system which is used for transmitting the surrounding rock images of the acquisition points to the image processing system; and an image processing system which is used for receiving the surrounding rock image, processing and splicing image information, and forming a complete surrounding rock image at a corresponding imaging position. According to the invention, surrounding rock image data can be acquired at different positions in the drilling and blasting tunnel, and the image data is processed, so that panoramic monitoring is realized.

Description

technical field [0001] The disclosure belongs to the technical field of tunnel imaging, and in particular relates to a panoramic imaging system and method based on a vehicle-mounted drilling and blasting tunnel. 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] In the process of tunnel construction, in order to analyze the development characteristics of cracks or joints in the surrounding rock, it is necessary to conduct on-site investigation of the surrounding rock in the tunnel, obtain the geological parameters of the tunnel surrounding rock, and monitor the tunnel surrounding rock to ensure the safety of the tunnel project. [0004] For tunnel construction, especially the construction of long tunnels, the acquisition and analysis of the development characteristics of surrounding rock cracks or joints mainly rely on methods such as on-sit...
