The phase error caused by the speed mismatch issue is researched in the line-scan images capturing 3D profile measurement.
The experimental system is constructed by a line-scan CCD camera, an object moving device, a digital fringe pattern projector, and a personal computer.
In the experiment procedure, the detected object is moving relative to the image capturing system by using a motorized translation stage in a stable velocity.
The digital fringe pattern is projected onto the detected object, and then the deformed patterns are captured and recorded in the computer.
The object surface profile can be calculated by the Fourier transform profilometry.
However, the moving speed mismatch error will still exist in most of the engineering application occasion even after an image system calibration.
When the moving speed of the detected object is faster than the expected value, the captured image will be compressed in the moving direction of the detected object.
In order to overcome this kind of measurement error, an image recovering algorithm is proposed to reconstruct the original compressed image.
Thus, the phase values can be extracted much more accurately by the reconstructed images.
And then, the phase error distribution caused by the speed mismatch is analyzed by the simulation and experimental methods.
