摘　　要：介绍了三维激光扫描测量的原理并对其理论测量误差进行了分析。采用三维激光扫描技术对广东省五华县崩岗一滑坡进行了6次观测,分析结果表明,三维激光扫描技术与传统的滑坡监测相比具有速度快、精度高、能实时三维动态显示滑坡变化及滑坡量等优点,在实时动态监测中具有广泛的应用前景。In this paper, we introduced the principle of 3D laser scanning measurement and analyzed the theory of measurement error. We used 3D laser scanning technologies to observe a landslide in the field of Wuhua Benggang in Guangdong Province six times. The results show that 3D laser scanning technologies compared with traditional landslide monitoring has quick speed, high precision, real-time 3D dynamic display. The advantages of real-time display amount change and landslide has extensive application prospect in the real-time dynamic monitoring.
