Abstract
Improved camera calibration techniques, including an improved up look angle and an improved method for calibrating a virtual center of projection. By using a view camera technique for the up look angle, the image sensors can be mounted flat to a Printed Circuit Board (PCB). By using a sub-region of the image sensor for the active area of the camera it is possible to calibrate the virtual center of projection (C′).
