چکیده
We are studying the geometry of a 360 x 360 mosaic image formation. A 360 x 360 mosaic camera model and a calibration procedure are proposed. It is shown that only one point correspondence is needed in order to acquire epipolarily rectified images. The 360 x 360 mosaic camera model is therefore determined by only one intrinsic parameter. It is shown that the relation between coordinates estimated with different values of intrinsic 360 x 360 mosaic camera parameters is a scaling of all scene point coordinates with additional nonlinear changes in the z coordinates of the scene points. Experimental results verifying the reconstruction of real scene points are presented.

متن کاملA Novel HDR Depth Camera for Real-Time 3D 360° Panoramic Vision
This paper presents a novel 360° High-Dynamic Range (HDR) camera for real-time 3D 360° panoramic computer vision. The camera consists of (1) a pair of bio-inspired dynamic vision line sensors (1024 pixel each) asynchronously generating events at high temporal resolution with on-chip time stamping (1µs resolution), having a high dynamic range and the sparse visual coding of the information, (2) ...
متن کاملOmnivergent Stereo - panoramas with a Fish - eye Lens ( Version 1 . 0 )
We present a novel approach to the calibration of an ultra wide angle fish eye lenses. These lenses have the field of view larger than 180◦, therefore the common calibration methods based on the classical pinhole camera model with a planar retina cannot be employed. A new camera model is proposed together with a calibration method for extracting its parameters. Experiments evaluating the propos...
متن کاملA panoramic 3D reconstruction system based on the projection of patterns
This work presents the implementation of a 3D reconstruction system capable of reconstructing a 360-degree scene with a single acquisition using a projection of patterns. The system is formed by two modules: the first module is a CCD camera with a parabolic mirror that allows the acquisition of catadioptric images. The second module consists of a light projector and a parabolic mirror that is u...

In recent years several depth cameras have emerged on the consumer market, creating many interesting possibilities for both professional and recreational usage. One example of such a camera is the Microsoft Kinect sensor originally used with the Microsoft Xbox 360 game console. In this master thesis a system is presented that utilizes this device in order to create an as accurate as possible 3D...
