Patent ID: 8754929

Claim:
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 x i and y i , thereby forming respective image matrices X = [ x 1 … x n y 1 … y n 1 … 1 ] said transformation being at least one of: multiplication of said X by the matrix ⁢ [ s ⁢ ⁢ cos ⁢ ⁢ α s ⁢ ⁢ sin ⁢ ⁢ α t x - s ⁢ ⁢ sin ⁢ ⁢ α s ⁢ ⁢ cos ⁢ ⁢ α t y 0 0 1 ] where s=1±ε and α is the small angle between the two images; multiplication of said X by the corresponding matrices [ 1 0 - δ 0 1 0 0 0 1 ] and [ 1 0 δ 0 1 0 0 0 1 ] when image pixels are offset by δ from either side of a desired vergence image location.
