    This study presents an adaptive algorithm for 3D shape measurement using computer-aided-design (CAD) models. This method efficiently recovers absolute 3D geometry from fringe images, even for complex objects.

    Area of Science:

    • Metrology
    • Computer Vision
    • Optical Measurement

    Background:

    • Conventional 3D shape measurement techniques often lack specificity.
    • Object geometry preknowledge can optimize measurement efficiency.
    • General methods may be suboptimal when CAD models are available.

    Purpose of the Study:

    • To introduce a novel adaptive algorithm for absolute 3D shape measurement.
    • To leverage object computer-aided-design (CAD) models for enhanced measurement accuracy and efficiency.
    • To demonstrate the algorithm's effectiveness with limited fringe images.

    Main Methods:

    • Exporting 3D point cloud data from CAD models.
    • Transforming CAD models into the camera perspective.
    • Obtaining wrapped phase maps from three phase-shifted fringe images.
