Systems and methodologies related to formatting data for 3-D viewing
Image acquisition instruments may be employed to capture images used to produce data for driving 3-D projectors. The data obtained from the image acquisition instruments may be compressed. Projectors may also be used to form 3-D images of the object based on the compressed data after decompressing the data. Accordingly, various embodiments described herein involve the formatting of the data such as compressing the data or un-compressing the data.
1. A method for processing complex image data, the method comprising:
obtaining complex optical image data of an object having an intensity portion and a phase portion; and
compressing the phase portion to yield a compressed phase data,
wherein said compressing said phase portion comprises averaging the phase in visually flat areas, wherein the visually flat areas comprise at least one of: (i) portions of the object with small variations in depth, or (ii) portions of the object that are at a distance from a human visual system greater than a threshold distance such that the human visual system cannot discern small variations in depth.
2. The method of claim 1 , wherein the complex image data includes data representative of an optical image resulting from an optical interference of an intensity image of the object and a reference beam.
3. The method of claim 2 , further comprising using an optical sensor to capture at least one image of the object to obtain said complex image data.
4. The method of claim 3 , further comprising using said optical sensor to capture an optical interferometric fringe pattern from the object.
5. The method of claim 1 , wherein the complex image data includes data representative of an optical image resulting from an interference of an intensity image of the object obtained through an imaging pupil and a reference beam.
6. The method of claim 1 , wherein the data includes a plurality of color components.
7. The method of claim 1 , further comprising compressing the intensity portion to yield compressed intensity data.
8. The method of claim 7 , further comprising transmitting said compressed intensity and phase data to a projector configured to project a 3-D image.
9. The method of claim 1 , wherein the visually flat areas comprise portions of the object with small variations in depth.
10. The method of claim 1 , wherein the visually flat areas comprise portions of the object that are at a distance from a human visual system greater than a threshold distance such that the human visual system cannot discern small variations in depth.
11. An apparatus for capturing data usable for 3-D image formation, the apparatus comprising:
an image acquisition component configured to capture one or more images of an object, at least a portion of the one or more images having depth information; and
one or more processors configured to generate data based on the one or more images, the data including information representative of an interference of an optical intensity image of the object and a reference beam, phase and amplitude information included in said data or being extractable from said data,
wherein said processor is further configured to compress said phase information by averaging the phase information in visually flat areas of the one or more images, wherein the visually flat areas comprise at least one of: (i) portions of the object with small variations in depth, or (ii) portions of the object that are at a distance from a human visual system greater than a threshold distance such that the human visual system cannot discern small variations in depth.
12. The apparatus of claim 11 , wherein said image acquisition component is configured to interfere an optical intensity distribution from the object with the reference beam to obtain an interference pattern.
13. The apparatus of claim 11 , wherein said image acquisition component is configured to interfere an optical intensity image of the object obtained through an imaging pupil and the reference beam.
14. The apparatus of claim 11 , wherein said image acquisition component and one or more processors are configured to generate said data using a method other than employing optical interference of an optical intensity image of the object and a reference beam.
15. The apparatus of claim 11 , wherein said data comprises an image including a fringe pattern.
16. The apparatus of claim 11 , wherein said data comprises phase and amplitudes.
17. The apparatus of claim 11 , wherein said image acquisition component comprises one or more devices selected from the group consisting of a camera, an interferometer, a range finder, a time-of-flight measurement device, Light Detection and Ranging (LIDAR), and Remote Ultra-Low Light Imaging (RULLI) or RULLI-like device.
18. The apparatus of claim 11 , wherein the visually flat areas comprise portions of the object with small variations in depth.
19. The apparatus of claim 11 , wherein the visually flat areas comprise portions of the object that are at a distance from a human visual system greater than a threshold distance such that the human visual system cannot discern small variations in depth.
