Latest Patents

Fei Han holds a patent for "Persistent calibration of extended reality systems." This innovative patent outlines systems and techniques for persistent calibration of an electronic device configured to implement an XR system. The process involves estimating and validating visual-inertial odometry (VIO) calibration parameters during an active XR session. The validation of these parameters is achieved through a strict calibration qualification using a thresholding module, machine learning module, or both. The initial calibration qualification occurs concurrently with the strict calibration qualification based on VIO performance. If the estimated VIO calibration parameters pass both qualifications, they are stored for future XR sessions. Additionally, persistent calibration of time alignment between the inertial management unit and the image sensor is performed during active XR sessions upon detection of time alignment issues.
