A novel 3D measurement technique uses a digital light processing (DLP) projector to capture object shapes. This flexible method simplifies calibration and removes geometric constraints for accurate 3D reconstruction.

Area of Science:

  • Optics and Photonics
  • Computer Vision
  • Metrology

Background:

  • Traditional 3D measurement methods often require strict geometric arrangements and precise calibration procedures.
  • Digital Light Processing (DLP) projectors offer potential for structured light-based 3D sensing but require robust projection modeling.

Purpose of the Study:

  • To introduce a new 3D measurement method utilizing a DLP projector.
  • To develop a flexible and simplified calibration procedure for the proposed 3D measurement system.

Main Methods:

  • Analysis of the DLP projector's projection model to establish a relationship between fringe patterns and projected fringe strips.
  • Development of a calibration method using a calibration plate without requiring precise plate movement.
  • Implementation of a 3D shape acquisition system with arbitrary camera and projector positioning.
