Generation of three-dimensional movies with improved depth control

摘要

Techniques for creating 3-D movies allow improved control over camera positioning parameters and editing of depth in post-process to provide for a smoother variation in the viewer's convergence distance and a more pleasant viewing experience. A director can define reference parameters related to a desired viewing experience, and camera positioning parameters are derived therefrom. A depth script specifying piecewise continuous variations in reference parameters can be applied in post-process to generate 3-D shots, scenes, or movies. These techniques can be applied in both computer-generated and live-action 3-D movies.

1. A method for creating a shot for a three-dimensional movie, the method comprising:
determining an apparent width of an object in a shot, the shot comprising a sequence of images, the apparent width being defined as a width of the object as it appears in one of the images; establishing a reference parameter value for each of a plurality of reference parameters, the plurality of reference parameters defining a far triangle and a near triangle associated with the shot, wherein at least some of the reference parameter values are established based on the apparent width of the object; determining, based on the reference parameter values, camera positioning parameters for a first camera and a second camera, the camera positioning parameters including an interaxial distance between the first camera and the second camera; and obtaining, using the camera positioning parameters, a respective sequence of images for the shot for each of the first camera and the second camera.
