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.
