Systems and methods for marking images for three-dimensional image generation

摘要

Methods and systems for image marking and generation of a three-dimensional (3D) image of an object are described. In an example, a computing device may be configured to receive a first set of images of an object that capture details of the object. The computing device may also be configured to receive a second set of images that include markings projected on the object and that are indexed to correspond to images of the first set of images. The computing device may be configured to spatially align images of the second set of images based on the markings projected on the object and determine respective images of the first set of images corresponding to spatially aligned images of the second set of images. The computing device may then generate a 3D image of the object from the respective images of the first set of images.

主权项

1. A method, comprising:
receiving, at a computing device, 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, wherein the images of the second set of images are captured while a pattern is projected on the object, and wherein the images of the second set of images have a lower resolution than the images of the first set of images; 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 having the lower resolution; determining, based on indexing of the images of the second set of images to the images of the first set of images, respective images of the first set of images that correspond to and are captured at the same respective angles as images of the second set of images that are spatially aligned; replacing the aligned respective second images with the respective images of the first set of images having higher resolution than the aligned respective second images; and generating a three-dimensional (3D) image of the object using the respective images of the first set of images having the higher resolution that replace the spatially aligned images of the second set of images having the lower resolution.
