摘　　要：三维坐标法是一种经常使用的三维激光扫描测量系统标定方法。本文通过分析三维坐标法标定精度的限制因素,提出了一种基于一维坐标的标定方法。由于回避了激光扫描传感器无法准确获得某特定点三维坐标的劣势,一维坐标法可以不受扫描点间距的影响,使得标定精度比常规的三维坐标法大大提高了。本文对这种一维坐标法进行了详细地理论分析和数学仿真,并给出了一个典型工程应用实例。3-D coordinate method is a general calibration method for laser scanning systems. By analyzing the factors limiting the calibration accuracy of 3-D coordinate method, this paper proposes a new calibration method based on 1-D coordinate. Avoiding the difficulty that laser scanning system cannot measure 3-D coordinates of a specific point, the 1-D coordinate-based calibration method can get rid of the influence of scanning resolution, resulting in much better calibration accuracy than 3-D coordinate method. This paper provides a detailed theoretical analysis and numerical simulation for this method, also presents a typical engineering application example.
