Abstract
An optical calibration system is configured to determine camera calibration information of a virtual reality camera. The optical calibration system comprises a light source, a first and a second planar grid, and an optical calibration controller. The light source is configured to backlight the first and the second planar grids. Each planar grid includes a plurality of fiducial markers that are backlit by the light source. The optical calibration controller determines camera calibration information of a virtual reality camera selecting and analyzing a plurality of captured images that include a portion of the first or the second planar grid with fiducial markers backlit.
