本文提出了一种新型经济高效的非接触式 3D 测量系统,该系统由两个转台和一个激光测距仪组成。不需要三轴(两个旋转轴和激光轴)之间的正交精度,即传感器单元的三个部分(两个转台和激光测距仪)不需要正交组装,降低了制造门槛。与传统仪器相比,还节省了非正交调整和重新校准的时间。为系统提出了一种计算算法来测量测量空间中的所有点,实验验证了该系统能够为室内和室外建筑测量提供相关性能。
A novel cost-effective non-contact 3D measurement system is proposed in this paper, which consists of two rotary tables and one laser range finder. No orthogonal accuracy between the three axes (two rotation axes and the laser axis) is required, i.e. the three parts of the sensor unit (two rotary tables and the laser range finder) need not be assembled orthogonally, which lowers the barrier to manufacture it. Time for adjustment and recalibration with non-orthogonality is also saved, compared to traditional instrument. A computing algorithm is proposed for the system to measure all the points in the measurement space, and the experiments validate that the proposed system is able to deliver relevant performance for indoor and outdoor construction measurement.
