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.

Key words: 3D terrestrial laser scanner, systematic errors calibration, self-calibration method, calibration parameters, HDS3000
