Camera Calibration Using Multiple Images
1 I n t r o d u c t i o n The formation of images in a camera is described by the pinhole model. This model can be specified by the camera's focal length, principal point, and the aspect ratio. These parameters are called intrinsic because they refer to properties inherent to the camera. In contrast, extrinsic parameters describe the translation and rotation of a camera with respect to an exter...
متن کاملLinear Catadioptric Camera Calibration from Sphere Images
A spherical object has been introduced into central catadioptric camera calibration through utilizing the properties of an image conic, which is the projection of the occluding contour of a sphere in the catadioptric image. However, previous calibration method using sphere images employs nonlinear optimization method and requires a good initial estimation to start the minimization. In this pape...
متن کاملThe Eurosdr Approach on Digital Airborne Camera Calibration and Certification
The comprehensive analysis of new digital airborne photogrammetric camera systems is an important topic right now. Faster than originally expected the new digital sensors phased into market and are already used in production processes. Furthermore, some national mapping agencies or system flyers have already decided to exclusively use digital imagers in future and already started to sell their ...
متن کاملAutomatic Camera Calibration for Images of Soccer Match
Camera calibration plays an important role in the domain of the analysis of sports video. Considering soccer video, in most cases, the cross-points can be used for calibration at the center of the soccer field are not sufficient, so this paper introduces a new automatic camera calibration algorithm focus on solving this problem by using the properties of images of the center circle, halfway lin...
متن کاملA Simple, Intuitive Camera Calibration Tool for Natural Images
The paper reports an interactive tool for calibrating a camera, suitable for use in outdoor scenes. The motivation for the tool was the need to obtain an approximate calibration for images taken with no explicit calibration data. Such images are frequently presented to research laboratories, especially in surveillance applications, with a request to demonstrate algorithms. The method decomposes...
