A REVIEW OF GEOMETRIC MODELS AND SELF-CALIBRATION METHODS FOR TERRESTRIAL LASER SCANNERS

摘要: Terrestrial laser scanning has been shown to be an invaluable technology for engineering measurement applications such as structural deformation and rockfall monitoring. In order ensure the quality of data captured these other applications, all systematic instrument errors must properly modelled, calibrated corrected prior using in subsequent stability or analyses. one popular modelling approach, range angular observations from a scanner are augmented with additive model terms that describe errors. Self-calibration methods can then used estimate coefficients models. This paper provides review current state-of-the-art terrestrial error models self-calibration methods, supported by real-dataset examples demonstrate need processes.
