Abstract

An important step of phase calculation-based fringe projection
systems is 3D calibration, which builds up the relationship between an
absolute phase map and 3D shape data. The existing 3D calibration
methods are complicated and hard to implement in practical environments
due to the requirement of a precise translating stage or gauge block. This
paper presents a 3D calibration method which uses a white plate with
discrete markers on the surface. Placing the plate at several random
positions can determine the relationship of absolute phase and depth, as
well as pixel position and X, Y coordinates. Experimental results and
performance evaluations show that the proposed calibration method can
easily build up the relationship between absolute phase map and 3D shape
data in a simple, flexible and automatic way.
