Uncalibrated Deflectometry with a Mobile Device on Extended Specular Surfaces
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 be densely reconstructed in their
entirety. This work is a first step towards developing a self-calibrating
Deflectometry procedure capable of taking 3D surface measurements of specular
objects in the wild and accessible to users with little to no technical imaging
experience
