We introduce a system and methods for the three-dimensional measurement of extended specular surfaces with high surface normal variations. Our system consists only of a mobile hand held device and exploits screen and front camera for Deflectometry-based surface measurements. We demonstrate high quality measurements without the need for an offline calibration procedure. In addition, we develop a multi-view technique to compensate for the small screen of a mobile device so that large surfaces can…

TLDR
A comparative assessment of the strengths and weaknesses of both measurement principles from the current perspective will show that deflectometry is now heading to become a serious competitor to interferometry.
Fast and accurate deflectometry with crossed fringes
Abstract Phase measuring deflectometry (PMD) acquires the two components of the local surface gradient via a sequence of two orthogonal sinusoidal fringe patterns that have to be displayed and…
Structured Highlight Inspection of Specular Surfaces
TLDR

Mesostructure from Specularity
TLDR
This work proposes a progressive acquisition system that captures a dense specularity field as the only information for mesostructure reconstruction and can efficiently recover surfaces with fine-scale geometric details from complex real-world objects with a wide variety of reflection properties.
