چکیده
Synonyms – Panoramic camera, spherical camera, catadioptric camera, fisheye camera, wide-angle camera Related Concepts – camera calibration – pinhole camera – radial distortion – omnidirectional vision – camera parameter (intrinsic, extrinsic) – intrinsic parameter matrix – structure from motion – epipolar geometry Definition An omnidirectional camera (from omni, meaning all) is a camera with a 360-degree field of view in the horizontal plane, or with a visual field that covers a hemisphere or (approximately) the entire sphere.

An Omnidirectional Vision-Based Moving Obstacle Detection in Mobile Robot
This paper presents a new moving obstacle detection method using an optical flow in mobile robot with an omnidirectional camera. Because an omnidirectional camera consists of a nonlinear mirror and CCD camera, the optical flow pattern in omnidirectional image is different from the pattern in perspective camera. The geometry characteristic of an omnidirectional camera has influence on the optica...
متن کاملDetecting Moving Objects with an Omnidirectional Camera and Subtraction Whose Background Image is Renewed
2 Detecting moving objects When we use a PTZ camera and background subtraction to detect moving objects, we must synchronize the PTZ of the camera and the PTZ of the background image. This paper describes a method a new method of detecting moving objects with an omnidirectional camera. The proposed method uses a fixed omnidirectional camera which can acquire images surrounding the camera, and b...
متن کاملDetecting moving objects from omnidirectional dynamic images based on adaptive background subtraction
2. DETECTING MOVING OBJECTS This paper describes a new method for detecting moving objects with an omnidirectional camera. The proposed method uses a fixed omnidirectional camera which can acquire images surrounding the camera and a background subtraction technique based on adaptively updating background images. In subtracting the background image from the input image, we consider the oscillati...
متن کاملCalibration of Omnidirectional Camera by Considering Inlier Distribution
This paper presents a new self-calibration algorithm of omnidirectional camera from uncalibrated images by considering the inlier distribution. First, one parametric non-linear projection model of omnidirectional camera is estimated with the known rotation and translation parameters. After deriving projection model, we can compute an essential matrix of the camera with unknown motions, and then...
متن کاملHigh-resolution Panoramic Movie Generation from Video Streams Acquired by an Omnidirectional Multi-camera System
Telepresence systems using an omnidirectional image sensor enable us to experience remote sites with rich sensation. An omnidirectional multi-camera system is more useful to acquire high-resolution omnidirectional images of outdoor scenes than a monocular camera system. However, exact calibration of the camera system is necessary to generate a panoramic movie. In this paper, we describe a panor...
