相机模型--Omnidirectional Camera all) 广角相机:在一个水平面有360度视野的相机,或视野能覆盖半个球或近似整个球的相机Background 背景知识 大多数商业相机可以使用 pinhole相机模型来描述,使用一个perspective projection 来建模。但是存在一些高畸变成像设备如广角相机,它们不能使用传统小孔相机模型来描述。 目前存在几...
两个这样的相机被背靠背放到一起,没有违反 the single viewpoint 约束,得到真正的 omnidirectional sensor. omnidirectional camera 可以在同一时间看到相机四周所有方向的物体 360度 视野 2 omnidirectional viewpoint 全方位视角点 这里首先解释一下为什么任意的成像系统需要满足 a single center of projection ? 假定我们...
The invention discloses a unified model of a catadioptric omnidirectional camera and a calibration method thereof. The unified model of the catadioptric omnidirectional camera is formed by a virtual unit ball, a virtual viewpoint, a normalization plane and an imaging plane. On the basis of the ...
omnidirectional catadioptric vision sensor and ten laser projectors. The proposed method completely describes the calibration process of the structured lights and the calibration mathematic model including the camera calibration, mirror position and structured-light calibration is given. This method takes ...

The use of omnidirectional vision systems have captured much interest in the last years, because it allows a robot to attain a 360° field of view around its central vertical rotation axis, without having to move itself or its camera. In fact, it has been a common solution for the main ...
