Real time vergence control for 3D video capture and display
First Claim
1. A method operative on a computer for altering vergence points for multiple detectors in real time, the method comprising:
- a pre-alignment step of converging the detectors on a chosen intermediate point by mechanical means, said pre-alignment step including a focal length adjustment of all said detectors;
a secondary alignment step whereby image features from said detectors are identified and used in a transformation to bring all images into substantially equal orientation and size;
a fine alignment step of aligning said images through at least one of a sum of differences squared algorithm or a Fourier transform algorithm;
a vergence step applied in correlated steps to move apparent vergence points evenly to a location nearer to or further away from said detectors;
each said detector image contains image pixels xi and yi, thereby forming respective image matrices

Abstract
This invention relates to the recording and display three-dimensional (3D) images, notably in real-time video capture. This invention focuses on the ability to alter vergence instantaneously through software in order to amend disparities caused by differences between focal length and vergence distance. No mechanical means are necessary for amending both horizontal and vertical disparity. The ability to vary vergence allows selected images to be made to appear behind, level with, or in front of a display screen. While the invention is useful for consumer displays in television and films, the invention may also be used, for example, for visualizing weather, for mapping, for seismic surveys or for aircraft flight control. It is applicable, in real time, throughout the electro-magnetic spectrum particularly in the visible, infra-red and microwave portions.
