Abstract
A LED panel wherein a plurality thereof are employed to construct a LED volume for filing simulated virtual environments wherein the LED panel of the present invention provides tracking of objects in the vicinity thereof such as but not limited to a camera wherein the tracking elements do not require post production removal. The LED panel includes a housing having a perimeter frame that has a transparent LED display mounted thereto. On the rear surface of the LED display or proximate thereto are a plurality of retroreflectors. The retroreflectors function to provide inside-out tracking of a camera disposed within the LED volume. The present invention further includes a plurality of lidar sensors and optical sensors mounted to the perimeter frame. The lidar sensors and optical sensors provide data for outside-in tracking of a camera within the LED volume. The retroreflectors can be provided in multiple alternate embodiments.
