| 本文通过将μ-base激光测距仪固定在经纬仪上形成一套组合测量系统，并对组合测量系统中测距仪与经纬仪的相对位置进行了精确标定，将激光测距仪测量得到的距离转换为经纬仪仪器中心到目标的距离，再结合经纬仪测量的目标角度值，形成一种适用于大尺寸、超高精度测量要求的三维测量系统。通过对组合系统的测距精度进行分析，提出了一套高精度的标定方法，使得经纬仪中心至目标点的测距精度可以达到16.9 μm。并在此标定精度下对组合系统的测点误差进行了分析，结果表明组合系统点位测量精度优于激光跟踪仪。因此，本文提出的经纬仪与激光测距仪组合测量系统能够满足工业领域中大尺寸、超高精度测量的要求。 |
| 英文摘要: |
| In this paper, a new combination measurement system is established by fixing the μ-base laser ranger on the theodolite. For, The relative position between the ranger and the theodolite in this combined measurement system was precisely calibrated, and the distance measured by the laser ranger was converted into the distance from the center of the theodolite to the target. Combined with the angle value measured by the theodolite, a three-dimensional measuring system which could be able to meet the requirements of the large-scale and ultra-high precision measurement was formed. By analyzing the accuracy of the combination system, a high precision calibration method was proposed, which makes the distance accuracy from the center of theodolite to the target point reach 16.9μm. The accuracy of the measurement system was analyzed, and the results showed that the measurement accuracy of the combination system was better than that of the laser tracker. Therefore, the combination of theodolite and laser ranger mentioned above provided a solution to the challenge of large scale and ultra-high precision measurement in the industrial field. |
