    Abstract

    We present an approach of modelling and calibration of an active laser beam-scanning triangulation measurement system. The system works with the pattern of two-dimensional beam-scanning illumination and one-dimensional slit-scanning detection with a photo-multiplier tube instead of a CCD camera. By modelling the system-fixed coordinate, we describe the formulation of 3D computation and propose a calibration method in terms of LSE using a planar fitting algorithm. As a sensor-dependent solution, the estimation is refined in the domain of sensing variables. Result of calibration of the real system and a brief analysis of systematic errors are given.
