Problems of internal calibration of precision laser triangulation 2D scanners

The article describes methods of calibration of two-dimensional laser triangulation scanners as applied to high-precision laser scanners with a small scanning range, which is very close to the body of scanner. Methods were tested via experiments on the calibration of the scanner. Values of measurement error and repeatability were collected after during experiments. As a result, there are conclusions about the suitability of existing methods using for calibration of this type of scanners.
