Abstract
A system is describes that includes a head mounted display (HMD) and a portable docking station configured to receive the HMD for calibration of one or more components of the HMD. The portable docking station includes at least one calibration target, e.g., a checkerboard pattern and/or a convex reflector. Techniques of this disclosure include calibrating an image capture device of the HMD based on one or more images of the calibration target captured by the image capture device when the HMD is placed in the portable docking station. The disclosed techniques may be applied to calibrate multiple different components of the HMD, including image capture devices such as eye-tracking cameras and inside-out cameras, displays, illuminators, sensors, and the like. In some examples, a rechargeable battery of the HMD may be charged when the HMD is placed in the portable docking station.
