Abstract (en)
[origin: WO9928704A1] Process for the measurement of three dimensional (3D) profiles by means of the projection of structured light, based on the measurement of the shift which each direction of projection undergoes due to the height of the object under measurement. The process includes the steps of determining the shift in pixel of the light codings, and/or of making sinusoidal the projected fringes, and/or of adding an automatic calibration procedure and/or of adding an automatic procedure which determines the geometrical and optical set-up of the system, given as input the required measurement constraints, and/or of integrating the measurement method called GCM with the measurement method called SGM.
