摘　　要：地面三维激光扫描仪的测量精度主要由扫描仪的测距测角精度决定。以VZ-400型扫描仪为例设计实验,运用基线比较法得到其测距精度为2 mm;通过建立测角误差模型得到其测角精度为1.5"。研究结果表明,在一定条件下,VZ-400型扫描仪的测距测角精度均符合仪器的标称精度。The measurement accuracy of terrestrial 3D laser scanner is mainly determined by the ranging and angle measurement accuracy of the scanner. Taking the VZ-400 scanner for example, we designed an experiment. And then, we used the baseline comparison method to get the ranging accuracy was 2 mm, and its angular accuracy was 1.5'obtained through the angle error model. The result shows that the ranging and angle measurement accuracy of VZ-400 scanner in line with the instrument nominal accuracy under certain condition.
