OpenCV is an important open-source package of computer vision routines (see Bradski and Kaehler (2008)). Sc. (Elec. Sc. (Elec. Phil. from Balliol College, Oxford in 1989. He spent three years on the faculty at the University of Iowa, ten years on the faculty at the University of California at Berkeley, and then moved to the University of Illinois. He served as program co-chair for IEEE Computer Vision and Pattern Recognition in 2000 and in 2011, general co-chair for CVPR 2006, and program co-chair for the European Conference on Computer Vision 2008, and is a regular member of the program committee of all major international conferences on computer vision.

In this setting, we assume once again that we observe n fiducial points Pi (i = 1, . . , n) whose positions in some world coordinate system are known, and minimize the mean-squared distance between the measured positions of their images and those predicted by the perspective projection equation with respect to a vector of camera parameters ξ in R11+q , where q ≥ 0, which might include various distortion coefficients in addition to the usual intrinsic and extrinsic parameters. (This assumes that the aspect-ratio and skew are unknown.

The larger the hole, the wider the cone and the brighter the image, but a large pinhole gives blurry pictures. Shrinking the pinhole produces sharper images but reduces the amount of light reaching the image plane, and may introduce diffraction effects. Keeping the picture in sharp focus while gathering light from a large area is the second main reason for using a lens. , its direction changes. According to Snell’s law, if r1 is the ray incident to the interface between two transparent materials with indices of refraction n1 and n2 , and r2 is the refracted ray, then r1 , r2 , and the normal to the interface are coplanar, and the angles α1 and α2 between the normal and the two rays are related by n1 sin α1 = n2 sin α2 .
