Hyper-realistic telepresence is achieved by mounting an array of carefully calibrated cameras on a monitor. High-quality, three-dimensional (3D) telepresence is predicated on highly stable camera positions, e.g., cameras calibrated to a fraction of a millimeter, which, during operation, stay in position to within a fraction of a millimeter. The typical, bezel-mounted camera array in a monitor experiences thermally induced post-calibration positional drift large enough to make hyper-realistic telepresence infeasible. This disclosure describes cameras that are mounted in a manner that leverages the thermal stability and isolation of the cover glass of the monitor to achieve extremely stable camera positioning that lasts through the entirety of a video recording or conferencing session, and into future sessions. Mounting cameras directly on the cover glass results in advantages other than thermo-mechanical stability, such as simplified design, modularized assembly, accurate eye-tracking resulting in a better 3D viewing experience, etc.
