Camera Autocalibration and the Calibration Pencil [PDF]

Journal of Mathematical Imaging and Vision, 2005
We study the geometric object given by the set of lines incident with the absolute conic. We see that this object is given by a pencil of quadrics of P5, which is characterized. We describe some of its most relevant properties for the camera autocalibration problem.

Camera autocalibration using Plucker coordinates [PDF]

IEEE International Conference on Image Processing 2005, 2005
We present new results on the Absolute Line Quadric (ALQ), the geometric object representing the set of lines that intersect the absolute conic. We include new techniques for the obtainment of the Euclidean structure that lead to an efficient algorithm for the autocalibration of cameras with varying parameters.

Autocalibration method for scanning electron microscope using affine camera model [PDF]

Machine Vision and Applications, 2020
This paper deals with the task of autocalibration of scanning electron microscope (SEM), which is a technique allowing to compute camera motion and intrinsic parameters. In contrast to classical calibration, which implies the use of a calibration object and is known to be a tedious and rigid operation, auto- or selfcalibration is performed directly on ...

Camera Autocalibration and Horopter Curves [PDF]

International Journal of Computer Vision, 2004
We describe a new algorithm for the obtainment of the affine and Euclidean calibration of a camera under general motion. The algorithm exploit the relationships of the horopter curves associated to each pair of cameras with the plane at infinity and the absolute conic. Using these properties we define cost functions whose minimization by

Capabilities and limitations of mono-camera pedestrian-based autocalibration [PDF]

2010 IEEE International Conference on Image Processing, 2010
Many environments lack enough architectural information to allow an autocalibration based on features extracted from the scene structure. Nevertheless, the observation over time of walking people can generally be used to estimate the vertical vanishing point and the horizon line in the acquired image.
