摘要 对三维激光扫描仪测量系统内符合精度进行了研究,通过对两组标靶点分别进行多次重复观测,然后以两个标靶点之间的测量距离作为判断标准。第1组在距离不同的情况下得出扫描仪内符合精度优于0. 6 mm,且100 m以内精度没有随着距离的增加而明显降低;第2组在测量角度不同的情况下得出扫描仪内符合精度在入射角大于30°时优于1 mm,15°左右时精度明显降低。 In this paper,the coincidence accuracy in the measurement system of 3D laser scanner is studied.By repeated observation of two groups of targets,the measurement distance between the two targets is taken as the judgment standard.In the first group,the coincidence accuracy in the scanner was better than 0.6 mm when the distance was different,and the accuracy within 100 m did not decrease significantly with the increase of distance.Second group in measuring Angle under the condition of different scanner precision is better than that of 1 mm when incident Angle is greater than 30°,15°around when precision is decreased obviously.
