Application of Laser Scanning Technology in 3D Underground Engineering Survey
Laser scanning is a non-contact measurement technology,which is widely used in engineering construction due to its accuracy and efficien-cy.On the basis of discussing the principle of laser scanning technology,this paper combines with the example of underground tunnel engineering,analyzes the application of laser scanning technology in measuring tunnel deformation,and clarifies the distribution and value of overbreak and un-derbreak in tunnel construction,which could provide reference for the application of laser scanning technology in underground engineering.
