Systems and Methods for Marking Images for Three-Dimensional Image Generation

A non-transitory computer readable medium having stored thereon instructions executable by a computing device to cause the computing device to perform functions comprising:

• receiving a first set of images of an object, wherein images of the first set of images are captured from respective angles with respect to the object;
• receiving a second set of images of the object, wherein images of the second set of images are captured from the respective angles with respect to the object and are indexed such that each image of the second set of images corresponds to a respective image of the first set of images, and wherein the images of the second set of images are captured while a pattern is projected on the object;
• matching portions of the pattern in each image of the second set of images to corresponding portions of the pattern in spatially neighboring images of the second set of images so as to spatially align the images of the second set of images;
• determining respective images of the first set of images corresponding to spatially aligned images of the second set of images, based on indexing of the images of the second set of images to the images of the first set of images;
• and
• generating a three-dimensional (3D) image of the object based on respective images of the first set of images determined to correspond to the spatially aligned images of the second set of images.

A system, comprising:

• a marking module configured to project on an object markings that depict a pattern;
• an image capturing module configured to receive a first set of images of the object, wherein images of the first set of images are captured from respective angles with respect to the object, the image capturing module further configured to receive a second set of images of the object, wherein images of the second set of images are captured from the respective angles with respect to the object and are indexed such that each image of the second set of images corresponds to a respective image of the first set of images, and wherein the images of the second set of images are captured while the pattern is projected on the object;
• and
• an image generation module coupled to the image capturing module and configured to match given portions of the pattern in each image of the second set of images to corresponding portions of the pattern in spatially neighboring images of the second set of images so as to spatially align the images of the second set of images, the image generation module further configured to determine respective images of the first set of images corresponding to spatially aligned images of the second set of images, based on indexing of the images of the second set of images to the images of the first set of images, and the image generation module further configured to generate a three-dimensional (3D) image of the object based on the respective images of the first set of images determined to correspond to the spatially aligned images of the second set of images.
