| 摘 要： | 介绍了地面三维激光扫描仪工作原理，采用自检校法对仪器系统误差进行标定并详细推导了自检校系统误差模型。利用徕卡HDS3000获取的数据进行分析计算，得到该仪器的系统误差值，同时对获取的数据进行改正，并通过检验点验证系统误差改正效果。实验表明，经过系统误差改正后，HDS3000扫描仪的测量准确度可以提高一倍，效果良好。

Research on Systematic Errors Calibration of 3D Terrestrial Laser Scanner |
| |
| Abstract: | On the basis of introduction to principle of terrestrial laser scanner (TLS), self-calibration method for systematic error determination of TLS was discussed and systematic error models were derived in detail. In order to test the correctness of error model, an experiment was conducted. Data obtained by Leica HDS3000 was used in experiment. First some data were used as control information to calculate instrumental systematic errors, and then others were used as check information to testify the correction effect of systematic errors. The Experiment results show, after correcting systematic errors, data accuracy obtained by HDS3000 improve a lot, which demonstrates the correctness of error model. |
