一、引言自1995年瑞士徕卡公司推出世界上第一台三维激光扫描仪的原型产品以来,三维激光扫描技术已经走过了十几年的历程。它是继GPS之后,测绘行业在技术上的又一次飞跃。传统的测量方式是单点测量,以获取单点的三维空间坐标,而三维激光扫描则自动、连续、快速地 I. Introduction Since the launch of the prototype product of the world’s first 3D laser scanner by Leica Geosystems in 1995, 3D laser scanning technology has gone through more than 10 years of history. It is after GPS, the surveying and mapping industry in technology another leap. The traditional method of measurement is a single point of measurement to obtain a single point of three-dimensional space coordinates, and three-dimensional laser scanning is automatic, continuous, fast
