Geometric Camera Calibration
Geometric camera calibration is a prerequisite for making accurate geometric measurements from image data and it is hence a fundamental task in computer vision. This article gives a discussion about the camera models and calibration methods used in the field. The emphasis is on conventional calibration methods where the parameters of the camera model are determined by using images of a calibrat...
متن کاملLine Based Camera Calibration in Machine Vision Dynamic Applications
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object and image spaces is discussed. This model is based on the equivalence between the vector normal to the interpretation plane in the image space and the vector normal to the ro...
متن کاملCamera Modelling and Calibration with Machine Vision Applications
Camera Modelling and Calibration with Machine Vision Applications Anders Ryberg Department of Signals and Systems Chalmers University of Technology Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. The camera calibration ...
متن کاملUsing Geometric Constraints for Fisheye Camera Calibration
This paper presents a technique to linearly calibrate a fisheye camera using the fact that the distortion is in the radial direction (angle preservation on the X-Y plane). First, a linear equation based on this constraint is proposed for estimating intrinsic/extrinsic parameters. The skewness in the intrinsic parameters is assumed to be zero in this paper. Second, a pure rotation for the fishey...
متن کاملGeometric Camera Calibration Using Circular Control Points
Modern CCD cameras are usually capable of a spatial accuracy greater than 1/50 of the pixel size. However, such accuracy is not easily attained due to various error sources that can affect the image formation process. Current calibration methods typically assume that the observations are unbiased, the only error is the zero-mean independent and identically distributed random noise in the observ...
