Abstract
Devices and techniques are described for automatically calibrating a camera system. The camera system undergoing calibration is coupled to a computing device and an automated positioning platform coupled to a target structure. The computing device acquires images from the camera of the target structure in a plurality of repeatable poses. From these acquired images, intrinsic camera parameters may be determined. Once determined, the parameters may be used to correct images acquired by the camera system.
