I am developing an industrial machine vision application that uses two LifeCam Studio cameras in a stereo camera configuration using OpenCV.
In order to perform a proper 3D stereo calibration, I need to disable the autofocus entirely. This is required because the focus is an improtant part of the optical characteristics and it is exactly this that the calibration procedure is trying to characterize. A proper calibraton cannot be performed if the camera's optical characteristics are changing.
This is also true for a single-camera 2D calibration.
Is there a published API for manipulating the camera? If not, when will it be released?
