Paper Abstract

We develop optical calibration and distortion correction for a recently developed DMD-based volumetric augmented reality display. The display is capable of displaying imagery over a large volume | composed of 280 depth planes over a large depth-range (15 cm to 400 cm) and 40 degrees field-of-view. An unintended property of this display is that the field-of-view of the depth planes changes slightly over depth. This can cause distortions, perceptual errors for the perspective depth cue, and reduce the image quality slightly. To address these issues, we develop an optical calibration method and a distortion correction as a post-processing step to our rendering pipeline.
