摘要
地面式三维扫描系统可以在极短时间内获取仪器视野内物体表面的坐标、反射率、色彩等数据,再通过转站扫描、数据拼接等内业处理,生产出准确、高效、多用途的三维点云数据模型.三维激光扫描技术突破了传统测量仪器单点测量的局限,能够在极大程度上还原现场,不仅能在传统测量领域发挥特长,还能够应用到工业逆向工程、建筑工程BIM管理、古建建模、事故现场复原等众多行业领域中.文章结合生产实践,从细节上阐述了点云数据实际生产流程及关键技术处理.
Abstract
Ground-based 3D scanning systems can quickly obtain coordinates,reflectance,color,and other data of objects within the instrument's field of view.Accurate,efficient,and versatile 3D point cloud data models can be setup through post-processing such as station scanning and data stitching.3D laser scanning technology has overcome the limitations of traditional single-point measurement instruments,greatly restoring the scene.This technology not only excels in traditional measurement fields but also finds applications in various industries such as industrial reverse engineering,construction en-gineering BIM management,historical building modeling,and accident scene reconstruction.This paper combines produc-tion practice to elaborate on the detailed actual production process and key technological processing of point cloud data.
