Photometric stereo with only two images: A theoretical study and numerical resolution
This work tackles the problem of two-image photometric stereo. This problem constitutes the intermediate case between conventional photometric stereo with at least three images, which is well-posed, and shape-from-shading, which is ill-posed. We first provide a theoretical study of ambiguities arising in this intermediate case. Based on this study, we show that when the albedo is known, disambi...
متن کاملUnambiguous Photometric Stereo Using Two Images
In the last years, the 3D reconstruction of surfaces which represent objects photographed by simple digital cameras has become more and more necessary to the scientific community. Through the most various mathematical and engineering methods, scientists continue to study the Shape-from-shading problem, using the photometric stereo technique which allows the use of several light sources, but kee...
متن کاملResolution-Enhanced Photometric Stereo
Conventional photometric stereo has a fundamental limitation that the scale of recovered geometry is limited to the resolution of the input images. However, surfaces that contain sub-pixel geometric structures are not well modelled by a single normal direction per pixel. In this work, we propose a technique for resolution-enhanced photometric stereo, in which surface geometry is computed at a r...
متن کاملEnhanced Photometric Stereo with Multispectral Images
We introduce a technique based on multispectral images aimed at improving Lambertian photometric stereo. Many photometric stereo algorithms assume Lambertian reflectance, but deviations from this ideal produce errors in shape reconstruction. To alleviate this problem, we exploit the wavelength-dependence of material reflectance. Based on the observation that reflectance at certain wavelengths f...
متن کاملPhotometric stereo without multiple images
Photometric Stereo (PMS) recovers orientation vectors from a set of graylevel images. Under orthography, when the lights are unknown, and for a single uniform Lambertian surface, one can recover surface normals up to an unknown overall orthogonal transformation. The same situation obtains if, instead of three graylevel images, one uses a single KGB image taken with at least three point or exten...
