Model - based Calibration of a Range Camera
This paper introduces a new method for the calibration of a range camera based on active triangulation. The technique is based on a model derived from the geometry of the synchronized scanner. From known positions of a calibration bar, a logistic equation is tted with values of spot positions read from a linear position detector at a number of angular positions of a scanning mirror. Furthermore...
متن کاملA New Analytical Radial Distortion Model for Camera Calibration
| Common approach to radial distortion is by the means of polynomial approximation, which introduces distortion-speci c parameters into the camera model and requires estimation of these distortion parameters. The task of estimating radial distortion is to nd a radial distortion model that allows easy undistortion as well as satisfactory accuracy. This paper presents a new radial distortion mode...
متن کاملA Mathematical Model for Camera Calibration Using Straight Lines
The aim of this paper is to present the derivation and experimental evaluation of a simultaneous method for camera calibration using straight lines. A mathematical model using straight lines was derived to consider both interior and exterior orientation parameters as unknowns. The interior orientation parameters to be estimated are the camera focal length, the coordinates of the principal point...
متن کاملCamera Calibration
where W = [W1,W2,W3] is a world point in the world reference frame, X = [X1, X2, X3] is W reexpressed in the camera’s reference frame, x = [x1, x2] is the projection of X in the canonical camera reference frame, ξ = [ξ1, ξ2] is x re-expressed in the image reference frame. The vector π = [π1, π2] is the principal point in image coordinates, f is the camera’s focal distance, and the diagonal elem...
متن کاملCamera Calibration
Camera calibration is a necessary step in 3D computer vision in order to extract metric information from 2D images. It has been studied extensively in computer vision and photogrammetry, and even recently new techniques have been proposed. In this chapter, we review the techniques proposed in the literature include those using 3D apparatus (two or three planes orthogonal to each other, or a pla...
