3d calibration method and apparatus for multi-view phase shift profilometry

Abstract

Disclosed is a three-dimensional (3D) calibration method and device for multi-view phase shift profilometry. A 3D calibration method for multi-view phase shift profilometry, performed by a computer device, according to an example embodiment may include acquiring a phase that is data required for 3D reconstruction from parameters of at least one camera and a projector based on a phase measuring profilometry (PMP) method; defining a phase-to-depth function for each camera-and-projector combination and performing calibration of optimizing the parameters of the camera and the projector; and acquiring a point cloud that includes depth information using the optimized parameters of the camera and the projector.

Dependencies are inferred from the claim text.
