Toward Shape from a Single Specular Flow
In “Shape From Specular Flow: Is One Flow Enough?” (Vasilyev, et al., 2011 [5]) we show that mirror shape can often be reconstructed from the observation of a single specular flow. In this technical report we provide additional details that, due to space constraints, could not be included in the paper. First we provide a derivation of the linear system for the reflection field derivative in the...
متن کاملUnique specular shape from two specular flows
When a curved mirror-like surface moves relative to its environment, it induces a motion field—or specular flow—on the image plane that observes it. This specular flow is related to the mirror’s shape through a non-linear partial differential equation, and there is interest in understanding when and how this equation can be solved for surface shape. Existing analyses of this ‘shape from specula...
متن کاملSpecular Flow and Shape in One Shot:
The reconstruction of specular shape from images is a very challenging task, especially when the illumination environment is unknown. In such cases, the problem becomes more tractable once the camera observes relative motion between the object and the environment, which induces a type of optical flow field that has become known as specular flow. Unfortunately, however, the estimation of specula...
متن کاملShape and Model from Specular Motion
This work investigates visual characteristics of specular surfaces during rotation, and gives approaches to qualitatively identify and quantitatively recover shapes of these surfaces. Continuous images are taken when an object rotates. We look at specularly reflected patterns on the surfaces and their motion in the EPIs parallel to the rotation plane, from which estimation of each surface point...
متن کاملDetermining Shape of Specular Surfaces
A new method for determining the shape of specular surfaces is presented in this paper. Our approach reconstructs the shape of specular surfaces from a relationship between the surrounding environment and the observed images of specular surfaces. A prototype system has been implemented. The experimental results show that the proposed method is effective to the reconstruction of specular objects...
