    Area of Science:

    • Computer Vision
    • Geometric Calibration
    • Photometric Calibration

    Background:

    • Standard pinhole model calibration is insufficient for laser projectors due to beam divergence.
    • Accurate registration of laser projection systems (GLP) onto complex 3D surfaces is challenging.
    • Merging GLP data with standard video projectors requires unified calibration.

    Purpose of the Study:

    • To develop a geometric calibration method for accurate GLP registration on 3D surfaces.
    • To enable seamless merging of GLP and video projector outputs.
    • To present a photometric calibration for unified color appearance.

    Main Methods:

    • An adapted calibration procedure for GLP systems, overcoming pinhole model limitations.
    • Geometric calibration using 2D vector input data for 3D surface registration.
    • Photometric calibration to match GLP color gamut with video projectors.

    Main Results:

    • Successful geometric registration of GLP onto complex 3D surfaces.
    • Accurate merging of 3D vertex data from GLP with calibrated video projectors.
    • Unified color appearance achieved between GLP and video projectors.

    Conclusions:

    • The proposed method enables accurate 3D projection mapping with GLPs.
    • The calibration facilitates straightforward content generation for mixed projection systems.
    • The approach maximizes GLP advantages while ensuring smooth visual integration.
