Interactive 3D Stereoscopic Dome with Automatic Calibration
In recent years, the advances in projection technology and the increasing rendering capacity of modern computers allowed the development of immersive digital domes. Digital dome systems are not limited to planetariums, but also find their way into science centers, theme parks, or multimedia events. However, most installations do not support 3D stereoscopic display, because of the difficulties t...
متن کاملUAV Motion Estimation Using Hybrid Stereoscopic Vision
Motion and velocity are essential parameters for an Unmanned Aerial Vehicle (UAV) during critical maneuvers such as landing or take-off. In this paper, we present a hybrid stereoscopic rig made of a fisheye and a perspective cameras for motion estimation. The rotation and translation are estimated by a decoupling. The fisheye view contributes to determine the orientation and the attitude while ...
متن کاملStereoscopic Light Stripe Scanning: Interference Rejection, Error Minimization and Calibration
This paper addresses the problem of rejecting interference due to secondary specular reflections, cross-talk and other mechanisms in an active light stripe scanner for robotic applications. Conventional scanning methods control the environment to ensure the brightness of the stripe exceeds that of all other features. However, for a robot operating in an uncontrolled environment, valid measureme...
متن کاملA Hybrid Approach for Error Concealment in Stereoscopic Images
Error concealment for stereoscopic images receives little attention in research of image processing. While many methods have been proposed for monocular images, this paper considers a concealment strategy for block loss in stereoscopic image pairs, utilizing the information of the associated image to fulfill the higher quality demand. We present a hybrid approach, combining a 2D projective tran...
متن کاملCalibration of a Hybrid Camera Network
Visual surveillance using a camera network has imposed new challenges to camera calibration. An essential problem is that a large number of cameras may not have a common field of view or even be synchronized well. We propose to use a hybrid camera network that consists of catadioptric and perspective cameras for a visual surveillance task. The relations between multiple views of a scene capture...
