Abstract
A head-worn device may be configured with a curved window-element that can generate distortion in images captured by a camera of the head-worn device. Window extrinsics describing the shape, orientation, and/or position of the curved window-element may be used as a calibration to reduce the distortion. An online calibration process may be run at times during use so that the window extrinsics can be updated to accurately represent the curved window-element after changes in the shape, orientation, and/or position of the curved window-element occur.
