Systems and methods for alignment, calibration and rendering for an angular slice true-3D display

摘要

Systems and methods for calibrating a 3D display system. In one embodiment, a system includes a display screen, 2D image projectors that project 2D projection images onto the screen and a camera that captures calibration images of the screen. A computer generates the 2D projection images, which include calibration patterns, and processes the captured calibration images. The computer uses the calibration images to calculate corrections based upon the calibration images. The computer can then generate corrected 2D projection images that are projected by the 2D image projectors onto the screen to produce a substantially visually correct 3D image with continuous viewing, true horizontal parallax, and a different view for each eye within a valid viewing zone. The corrections to the images may include corrections to the geometry (including distortion, alignment, etc.) color (including intensity and related parameters).

主权项

1. A 3D display calibration system comprising:
a display screen; a camera configured to capture calibration images of the screen; one or more 2D image projectors configured to project a plurality of 2D projection images onto the screen, wherein a projection frustum for the 2D projection images has different locations for a horizontal focus and a vertical focus, wherein the horizontal focus is a vertical line at the 2D image projector and the vertical focus is a horizontal line at a viewer position; and a computer configured to generate the 2D projection images and to process the calibration images captured by the camera; wherein the 2D projection images are calibration patterns; wherein the camera captures the calibration images of the screen while the calibration patterns illuminate the screen; wherein the computer calculates corrections to the 2D projection images in dependence upon the calibration images.
