Abstract
Abstract
Universal industrial-applicable calibration method for optical-electronic triangulation systems using structured illumination for 3D geometry measurements is proposed. An analytical and experimental estimations of the measurement error due to the method of phase steps and system calibration were obtained. The method has a simple implementation when measuring the 3D geometry of large objects. It is shown, that proposed method can be effectively used in measurement systems constructed on a standard low-cost element base.
