摘　　要：提出了一种用经纬仪和卡尺组合测量大长度滑轨定位误差的方法。针对运动滑块的测试结果,采用迭代最小二乘法辨识出经纬仪至卡尺刻线轨迹的位置参数,并计算出每次运行的位移误差。误差分析与实验结果,证明本文提出的方法能够达到测试准确度的要求。A new method combining a theodolite and a caliper is presented for large-size slide rails. After test results were collected, the iterated least square method was used to identify the position parameters of the theodolite to the track of the caliper scales, and the individual displacement errors of the slide rail were calculated. The experimental results and error analysis show that this method can meet the requirements for the measurement accuracy.
