Abstract
As a widely utilized non-contact measurement technology,3D laser scanning has gained extensive application in engineering construction due to its inherent advantages of high precision,efficiency,and automation.Based on a practical engineering case from a major underground laboratory project in Sichuan Province,elaborates on the specific applications of this technology in field data acquisition,point cloud processing,model construction,and accuracy validation.By establishing a control network and deploying target balls,multi-station scanning was conducted to capture three-dimensional point cloud data of complex underground spaces.Through processing steps such as registration,noise reduction,and coordinate transformation,a high-precision 3D point cloud model was generated.Furthermore,the multifaceted applications of 3D point clouds in graphic drawing(e.g.,floor plans,cross-sectional drawings)and BIM design were explored,including reverse modeling,collision detection,and spatial optimization,providing reliable foundational data and technical upport for the digital design and intelligent operation and maintenance of underground engineering.The research demonstrates that this technology holds significant practical value and broader application prospects in undergroun spatial measurement.关键词
