Creating 3D images of objects by illuminating with infrared patterns

A device comprising:

• a camera configured to generate first and second images of an object illuminated with a pattern;
• and
• a processor configured to:
• establish a first-pair correspondence between initial matched pixels of the first and second image based on detecting the illuminated pattern in the first and second images,
• identify a depth discontinuity associated with the object based on a deformation of the illuminated pattern,
• control a disparity propagation of the initial matched pixels in two directions based on the identified depth discontinuity, and
• generate a three-dimensional reconstruction of the object based on the controlled disparity propagation.

A computer-implemented method comprising:

• using at least one processor to perform operations comprising:
• receiving first and second pairs of images in a sequence of paired images of an object illuminated with a pattern;
• and
• for each of the first and second pairs of images:
• establishing a first-pair correspondence between initial matched pixels of the paired images based on detecting the illuminated pattern in the paired images,
• identifying a depth discontinuity associated with the object based on a deformation of the illuminated pattern,
• controlling a disparity propagation of the initial matched pixels in two directions based on the identified depth discontinuity, and
• generating a three-dimensional reconstruction of the object based on the controlled disparity propagation.
