Panoramic 3D Reconstruction Using Rotating Camera with Planar Mirrors

In this paper, we propose a novel approach for obtaining 3D information of panoramic (360 degrees) environments. We design an image acquisition rig composed with a camera and two planar mirrors. The regular image captured by the camera is separated into uncontinuous three regions by the mirrors arranged in front of the camera. By rotating the rig about a vertical axis with a constant velocity, ...

Rotating beams in isotropic optical system.

Based on the ray transformation matrix formalism, we propose a simple method for generation of paraxial beams performing anisotropic rotation in the phase space during their propagation through isotropic optical systems. The widely discussed spiral beams are the particular case of these beams. The propagation of these beams through the symmetric fractional Fourier transformer is demonstrated by...

An Image Stabilization Optical System Using Deformable Freeform Mirrors

An image stabilization optical system using deformable freeform mirrors is proposed that enables the ray sets to couple dynamically in the object and image space. It aims to correct image blurring and degradation when there is relative movement between the imaging optical axis and the object. In this method, Fermat's principle and matrix methods are used to describe the optical path of the enti...

Tracking of Rotating Objects

A representation of a three-dimensional object is autonomously learned from a sequence of the rotating object. The representation consists of single views in form of graphs and is achieved by performing a segmentation-based tracking of the object. First we apply a segmen-tation algorithm which is based on gray level values. This provides the location of the object in the images and a rough shap...
