1. A system comprising:
a stereoscopic head up display (HUD) comprising:
a combiner; and
a display configured to display a stereo media image, the stereo image being reflected off the combiner and received by an operator;
a tracking sensor configured to generate and transmit a tracking dataset;
one or more processors communicatively coupled to the display and the tracking sensor; and
a memory communicatively coupled to the one or more processors with instructions stored thereon, wherein the instructions, upon execution by the one or more processors, causes the one or more processors to:
receive the tracking dataset;
generate a set of distortion maps based on the tracking dataset and a distortion function;
receive a media stereo image signal;
generate a pre-distorted stereo image signal based on the set of distortion maps and the media stereo image signal, wherein a position of a pixel of the media stereo image signal is modified based on a corresponding pixel point of the distortion map; and
transmit the pre-distorted stereo signal to the display, wherein the pre-distorted stereo signal is displayed as a pre-distorted stereo media image, wherein upon reflection off the combiner, the pre-distorted stereo media image is corrected, and received by the operator as a flat image focused at infinity,
wherein the tracking dataset comprises a pair of eye positions.
