چکیده

ku and kv are the focal lenght expressed in pixel unit. They are close related to real f focal lenght and τ aspect ratio but this syntax is slightly more compact. K converts from camera coordinates to image coordinates (expressed in homogeneous form). The R is the rotation matrix. Since in R a unique reference frame not exists to model rotation from 3 angles we are not to deal with the inner form of this matrix. The important stuff is that R is a rotation matrix or rather it is an orthonormal matrix. R converts from world coordinates to camera coordinates (can handle for example a permutation term in order to switch from world reference frame to camera reference frame).

Flexible calibration method for microscopic structured light system using telecentric lens.

This research presents a novel method to calibrate a microscopic structured light system using a camera with a telecentric lens. The pin-hole projector calibration follows the standard pin-hole camera calibration procedures. With the calibrated projector, the 3D coordinates of those feature points used for projector calibration are then estimated through iterative Levenberg-Marquardt optimizati...

Pin-hole Modelled Camera Calibration from a Single Image

Camera calibration from a single image is of importance in computer vision. It requires a priori scene information. In recent years, some methods have been studied to solve this problem. One approach is to adopt the idea of using vanishing points and vanishing lines. Circles and balls are also introduced for the calibration target. Besides, symmetry and coplanar points and lines can be applied ...

Direct Self-Calibration of Central Catadioptric Omnidirectional Cameras

Calibrating a camera means determining the geometric properties of the imaging process, i.e., the transformation that maps a three-dimensional point, expressed with respect to a reference frame, onto its two-dimensional image whose coordinates are expressed in pixel units. This process is required when recovering 3D information. More precisely, we have to know the translation and rotation of th...

CMSC733: Camera Calibration Techniques

Camera calibration is the process of estimating the parameters of the camera. There are two sets of parameters for a camera: intrinsic parameters, and extrinsic parameters. It is generally assumed that we know the coordinates of a set of points in the world reference frame and their corresponding points in one or more images. The notations used and the general problem of calibration is describe...

Camera 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...
