Free-Form Mirror Design Inspired by Photometric Stereo

چکیده
A significant issue in the design of catadioptric imaging systems is what shape the component mirrors should take. In this paper, we propose a novel algorithm for designing a free-form mirror. A free-form mirror expressed as the assembly of its gradients, is the most flexible surface representation that can form various shapes. We improve the shape reconstruction framework used in a photometric stereo scheme for use in the design of free-form mirrors for catadioptric imaging systems. An optimal mirror shape is created to produce the best possible desired projection, under integrability conditions in order to be a consistent surface. Curved mirrors are designed for various catadioptric configurations and these design experiments confirm that the resulting free-form mirrors can approximate the desired projections.

متن کاملA Markov Random Field Approach for Dense Photometric Stereo
We present a surprisingly simple system that allows for robust normal reconstruction by photometric stereo using a uniform and dense set of photometric images captured at fixed viewpoint, in the presense of spurious noises caused by highlight, shadows and non-Lambertian reflections. Our system consists of a mirror sphere, a spotlight and a DV camera only. Using this, a dense set of unbiased but...

A simple 3D virtual mirror interface system is proposed for acquisition and reconstruction of facial pattern, which enables a real time tracking of 3D facial pattern. The movement of lip in the face, which can be estimated based on mean shift and Kalman filter is introduced to recognize the rotation and parallel shift of face. Modified Photometric Stereo Method (PSM) is also proposed to acquire...
متن کاملA Green's function approach to shape from shading
We present a new algorithm for shape from shading, inspired on the recently introduced disparity-based approach to photometric stereo. Assuming that the single input image will be matched to a second image through a uniform disparity eld, we construct an irradiance conservation equation and solve it for the matching image, via Green's function. When a linear expansion of the reeectance map is c...
