Concentric Panorama Geometry

چکیده
In this paper, the geometric relationship between mosaic images for concentric panorama acquired by slit cameras along circular paths is considered. A concentric epipolar constraint is derived for mosaic images. It is shown how the concentric epipolar constraint can be used to calibrate the slit camera using point correspondences in two mosaic images. The concentric epipolar constraint is further extended to trifocal geometric relationships for three mosaic views. Keywords— concentric panoramas; mosaic images; epipolar geometry; fundamental matrix; scene navigation

Compression of Concentric Mosaic with Rebinning of Slits (ross)
Concentric mosaic offers a quick solution for the construction and navigation of a virtual environment. However, the associated huge amount of data presents a heavy burden for its application. In this paper, we propose the rebinning of slits (ROSS) approach for the compression of concentric mosaic. The proposed scheme decorrelates the 3D concentric mosaic data set by rebinning the vertical slit...
متن کاملPanorama Measurement Based on Spherical Projective Geometry
Previous panoramic studies focused on image stitching and the panoramic camera development. In recent years, people began to focus on panoramic scalability issues, the existed methods adopt traditional photogrammetric methods for data processing based on a multi-directional panorama images, using a large number of control points and combined bundle adjustment. Indeed, panorama itself is a kind ...
متن کاملThe Design of a Stereo Panorama Camera for Scenes of Dynamic Range
Existing stereo panorama cameras do not allow controllability of pictorial/scene composition and stereo acuity (depth levels) over dynamic 3D scene ranges. We specify the design of such a camera allowing this type of flexibility. Previous approaches to design panorama cameras even lack studies with respect to this important aspect, while other design issues such as epipolar geometry, optics opt...
متن کاملProjective Texture Mapping with Full Panorama
Projective texture mapping is used to project a texture map onto scene geometry. It has been used in many applications, since it eliminates the assignment of fixed texture coordinates and provides a good method of representing synthetic images or photographs in image-based rendering. But conventional projective texture mapping has limitations in the field of view and the degree of navigation be...
متن کاملLeft ventricular concentric geometry is associated with impaired relaxation in hypertension: the HyperGEN study.
AIMS We tested the hypothesis that abnormal left ventricular (LV) relaxation is associated with concentric LV geometry. METHODS AND RESULTS Doppler LV filling properties were studied in 1384 hypertensive participants without cardiovascular disease, from the HyperGEN population (731 women, 784 obese, 236 diabetic) and compared in four LV geometry groups; normal, concentric remodelling (3.5%), ...
