摘要
手持激光扫描仪HandySCAN 700标称精度较高,本实验讨论了该仪器的内符合精度、体积精度、连续扫描长度的增加与精度的衰减关系以及被扫描物体颜色和粗糙度对扫描速度的影响。结果表明测试HandySCAN 700内符合精度较高,体积精度不稳定,精度随连续扫描长度的增加呈线性衰减,扫描速度与目标的颜色有直接关系,但与目标表面的粗糙度关系不大。
The handheld laser scanner HandySCAN 700 has a high nominal precision.The experiment is designed to test its inner coincidence precision,volume accuracy,therelationship between the precision attenuation and the increase of the continuous scan length,and the influence of color and roughness on velocity of scanning.The results show that the precision of inner coincidence of HandySCAN 700 is high;that the volume accuracy is not stable and the accuracy is roughly linearly attenuated with the increase of the continuous scan length;and that the velocity of scanning is directly related to the color of the target,but not to the roughness of the target surface.
