Abstract: The present disclosure relates to methods and devices for data or graphics processing including an apparatus, e.g., a GPU. The apparatus may determine a plurality of viewing positions and a plurality of viewing directions for one or more lenses. The apparatus may also measure an amount of distortion of the one or more lenses for each of the plurality of viewing positions and each of the plurality of viewing directions. Also, the apparatus may adjust pre-distortion data for each of the plurality of viewing positions and each of the plurality of viewing directions. The apparatus may also determine a pre-distortion estimation for each of the plurality of viewing positions and each of the plurality of viewing directions. The apparatus may also generate lens calibration data for all of the plurality of viewing positions and all of the plurality of viewing directions based on the pre-distortion estimation.
