Camera 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...
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 Self-Calibration with Known Camera Orientation
support for the camera interfaces. My colleagues Felix Woelk and Kevin Köser I would like to thank for many fruitful discussions. I thank our system administrator Torge Storm for always fixing my machine and providing enough data space for all my sequences which was really a hard job. Of course I also would like to thank the other members of the group Jan Woetzel, Daniel Grest, Birger Streckel ...
متن کاملCalibration of Camera Systems
Multiple camera systems including combinations of vertical and oblique images like used by Pictometry and Multivision are becoming popular very fast. The image combinations easily can be used for interpretation and also for metric purposes. In most cases the orientation is based on direct sensor orientation, using inertial measurement units and relative kinematic GPS-positioning. Usually this w...
متن کاملCamera Calibration with a Viewfinder
To answer the industrial need for simple camera calibration procedure, we propose a new method that requires a simple calibration object composed simply of a box and two crosses. The box is opened in the front where a large cross, made of wires, is attached while another is drawn (or attached) at the bottom. Both crosses are perfectly aligned similarly to a viewfinder. The viewfinder is first o...
