地面激光掃描儀是通過激光束測量距離以構建高精度三維點雲模型。 Terrestrial Laser Scanner is a ground-based scanning technology to capture highly accurate three-dimensional point cloud models by measuring distances using laser beams. 在油麻地停車場⼤廈第⼀階段拆卸工程中，工程團隊採用 自動變形監測系統實時監測⼤廈結構的移位情況。 During Phase 1 of the Yau Ma Tei Carpark Building demolition, Automatic Deformation Monitoring System was deployed to monitor the real-time movement of sensitive parts of the building. 路政署於⼆零零六年首次引入地面激光掃描技術，當時 掃描速率約為每秒 1,800 個點雲。隨着科技進步，現今 的掃描速率已提升至最高可達每秒 200 萬個點雲，精度 達毫米級，大幅提升數據採集效率與細節解析度。 When the Highways Department first introduced Terrestrial Laser Scanner in 2006, the scan rate was about 1,800 points per second. Today, advances in technology have increased the rate to up to 2 million points per second with millimetre-level accuracy, enabling faster and more detailed data collection. 126 測建路 智 Innovative Survey Technology and Application 激光掃描 Laser Scanning Technology
