Apparatus and method for calibrating multi-layer three-dimensional (3D) display

摘要

Provided is an apparatus and method for calibrating a multi-layer three-dimensional (3D) display (MLD) that may control a 3D display including a plurality of display layers to display a first image on one of the plurality of display layers, acquire a second image by capturing the first image, calculate a homography between the display layer and an image capturer based on the first image and the second image, and calculate geometric relations of the display layer with respect to the image capturer based on the calculated homography.

1. A method of calibrating a three-dimensional (3D) display including a plurality of display layers, the method comprising:
controlling, for each of the plurality of display layers, the 3D display to display an associated first image on a display layer of the plurality of display layers, wherein the associated first image is a two-dimensional (2D) image and the associated first image is displayed on the 3D display; acquiring, for each of the plurality of display layers, an associated second image by controlling an image capturer to capture the displayed associated first image; calculating, for each of the plurality of display layers, a homography matrix between the display layer and an image plane of the image capturer, based on the associated first image and the associated second image; calculating, for each of the plurality of display layers, geometric relations of the display layer with respect to the image plane of the image capturer, based on the calculated homography matrix; and obtaining geometric relations among the plurality of display layers based on the geometric relations of each of the plurality of display layers.
