1. A method of creating a perspective image (3-Dimensional image or 3D image) as perceived from a predefined reference view point, comprising: providing a first digital projector having a first projection region arranged along a first orientation with reference to a reference base; providing a second digital projector having a second projection region arranged along a second orientation with reference to said reference base, said second projection region at least partially overlapping said first projection region; defining a 3D imaging region within the overlapping area of said first projection region and said second projection region; establishing a first light transport matrix T 1 covering the portion of the first projection region that encompasses said 3D imaging region, said first light transport matrix T 1 relating a first image c 1 as viewed from said predefined reference view point to a first projected image p 1 from said first digital projector according to relation c 1 =T 1 p 1 ; establishing a second light transport matrix T 2 covering the portion of the second projection region that encompasses said 3D imaging region, said second light transport matrix T 2 relating a second image c 2 as viewed from said predefined reference view point to a second projected image p 2 from said second digital projector according to relation c 2 =T 2 p 2 ; providing a first imaging sequence to said first digital projector, said first imaging sequence providing a first angled view of an image subject within said 3D imaging region with reference to said reference view point as defined by said first light transport matrix T 1 ; providing a second imaging sequence to said second digital projector, said second imaging sequence providing a second angled view of said image subject within said 3D imaging region with reference to said reference view point as defined by said second light transport matrix T 2 ; wherein establishing said first light transport matrix T 1 , includes: using a camera at said predefined reference view point, capturing a reference noise image C 0 of at least part of said first projection region under ambient light with no image projected from said first digital projector; using said camera at said predefined reference view point, capturing a first image of a first test pattern projected by said first digital projector within said first projection region, said first test pattern being created by simultaneously activating a first group of projection pixels within said first digital projector, all projection pixels not in said first test pattern being turned off; using said camera at said predefined reference view point, capturing a second image of a second test pattern projected by said first digital projector within said first projection region, said second test pattern being created by simultaneously activating a second group of projection pixels within said first digital projector, all projection pixels not in said second test pattern being turned off, wherein said first and second groups of projection pixels have only one projection pixel in common defining a target projection pixel; subtracting said reference noise image C 0 from said first image to make a first corrected image; subtracting said reference noise image C 0 from said second image to make a second corrected image; comparing image pixels of said first corrected image to corresponding image pixels of said second corrected image and retaining the darker of two compared image pixels, the retained image pixels constituting a composite image; identifying all none-dark image pixels in said composite image; selectively identifying said none-dark pixels in said composite image as non-zero light transport coefficients associated with said target projection pixel; and wherein identified non-dark image pixels are arranged into adjoining pixel cluster according to their pixel position relation within an image, and only pixels within a cluster having a size not less than a predefined number of pixels are identified as non-dark pixels.
