Abstract
An augmented reality (AR) vision system is disclosed. A display is configured to present a surrounding environment to eyes of a user of the AR vision system. A depth tracker is configured to produce a measurement of a focal depth of a focus point in the surrounding environment. Two or more image sensors receive illumination from the focus point and generate a respective image. A controller receives the measurement of the focal depth, generates an interpolated look-up-table (LUT) function by interpolating between two or more precalculated LUTs, applies the interpolated LUT function to the images to correct a parallax error and a distortion error at the measured focal depth, generates a single image of the surrounding environment, and displays the single image to the user.
