Simple fish-eye calibration method with accuracy evaluation
In this paper, a simple fish-eye radial distortion calibration procedure is described. This method avoids costly minimisation and optimisation algorithms, and is based on trivial concentricity of three extracted points. The results show that this simplicity is at the expense of increased deviation of results (and thus increased error). However, this deviation can be reduced significantly by the...
متن کاملFish-Eye-Stereo Calibration and Epipolar Rectification
The paper describes calibration and epipolar rectification for stereo with fish-eye optics. While stereo processing of classical cameras is state of the art for many applications, stereo with fish-eye cameras have been much less discussed in literature. This paper discusses the geometric calibration and the epipolar rectification as prerequisite for stereo processing with fish-eyes. First, it s...
متن کاملAccuracy of fish-eye lens models.
The majority of computer vision applications assumes that the camera adheres to the pinhole camera model. However, most optical systems will introduce undesirable effects. By far, the most evident of these effects is radial lensing, which is particularly noticeable in fish-eye camera systems, where the effect is relatively extreme. Several authors have developed models of fish-eye lenses that c...
متن کاملA Simple Calibration Procedure for Fish-Eye (High-Distortion) Lens Camera
This paper presents a new algorithm for the geometric camera calibration of a fish-eye lens (a high distortion lens) mounted on a CCD TV camera. The algorithm determines a mapping between points in the world coordinate system and their corresponding point locations in the image plane. The parameters to be calibrated are effective focal length, one-pixel width on the image plane, image distortio...
متن کاملIntrinsic parameter calibration procedure for a (high-distortion) fish-eye lens camera with distortion model and accuracy estimation
-This paper presents a calibration procedure for a fish-eye lens (a high-distortion lens) mounted on a CCD TV camera. The method is designed to account for the differences in images acquired via a distortion-free lens camera setup and the images obtained by a fish-eye lens camera. The calibration procedure essentially defines a mapping between points in the world coordinate system and their cor...
