A panoramic imaging system and method based on a vehicle-mounted drill-and-blast tunnel

Abstract

The present disclosure provides a panoramic imaging system and method based on a vehicle-mounted drilling and blasting tunnel, including a mobile vehicle, used for mobile measurement, and obtaining the test point position of surrounding rock imaging; an image acquisition system, including a spherical transparent protective shell, And the multiple cameras set in the spherical transparent protective shell are used to collect images of surrounding rocks in different directions at the corresponding test points; the moving mechanism is set on the mobile vehicle to carry the image acquisition system and drive the image acquisition system to move to the specified tunnel end face. Location; data transmission system, used to transmit the surrounding rock image at the collection point to the image processing system; image processing system, used to receive the surrounding rock image, process and stitch image information, and form a complete surrounding rock image at the corresponding imaging position. The disclosure can collect surrounding rock image data at different positions in the drilled and blasted tunnel, and process the image data to realize panoramic monitoring.

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...

AI Technical Summary

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
