Calibration of a laser stripe profiler

Abstract

The calibration of a laser stripe profiler consisting of a laser stripe projector camera and a linear motion table is considered. A nonlinear system model is used which accommodates radial distortion in the camera lens. The way in which stripe data is extracted from the camera images lends to a natural formulation of the calibration problem as a nonlinear least squares problem. This can then be solved using standard techniques.
