  • Patent number: 10410410
    Abstract: Systems and methods are disclosed for generating viewpoints and/or digital images of defects in a three-dimensional model. In particular, in one or more embodiments, the disclosed systems and methods generate exterior viewpoints by clustering intersection points between a bounding sphere and rays originating from exterior vertices corresponding to one or more defects. In addition, in one or more embodiments, the disclosed systems and methods generate interior viewpoints by clustering intersection points between one or more medial spheres and rays originating from vertices corresponding to interior vertices corresponding to one or more defects. Furthermore, the disclosed systems and methods can apply colors to vertices corresponding to defects in the three-dimensional model such that adjacent vertices in the three-dimensional model have different colors and are more readily discernable.

  • Patent number: 10347052
    Abstract: Local color information in a 3D mesh is used to enhance fine geometric features such as those in embroidered clothes for 3D printing. In some implementations, vertex color information is used to detect edges and to enhance geometry. In one embodiment, a 3D model is projected into a 2D space to obtain a 2D image, so that pixels that lie on edges in the 2D image can be detected. Further, such edge information is propagated back to the 3D model to enhance the geometry of the 3D model. Other embodiments may be described and/or claimed.

  • Publication number: 20190005043
    Abstract: Automated digital asset tagging techniques and systems are described that support use of multiple vocabulary sets. In one example, a plurality of digital assets are obtained having first-vocabulary tags taken from a first-vocabulary set. Second-vocabulary tags taken from a second-vocabulary set are assigned to the plurality of digital assets through machine learning. A determination is made that at least one first-vocabulary tag includes a plurality of visual classes based on the assignment of at least one second-vocabulary tag. Digital assets are collected from the plurality of digital assets that correspond to one visual class of the plurality of visual classes. The model is generated using machine learning based on the collected digital assets.

  • Patent number: 10022914
    Abstract: A computer implemented method and apparatus for automatically adding utility holes to printable 3D models by accessing a digital representation of a 3D model; accessing specifications that define the geometry of a utility hole to be included with the 3D model; performing a heuristic evaluation of the digital representation of the 3D model to determine one of one or more possible placements of the utility hole to be included with the 3D model as a placement for the utility hole; modifying the digital representation of the 3D model so as to include the utility hole at the placement; and providing a modified digital representation of the 3D model for printing.

  • Patent number: 10019848
    Abstract: Techniques are disclosed for noise reduction and color smoothing of scanned 3D models for 3D printing. An anisotropic box kernel variant of a bilateral filter is applied to each vertex of a 3D mesh model, where the vertices contain color information. With bilateral filtering, the color at a given vertex is, under certain conditions, replaced by a Gaussian weighted average of colors of neighboring vertices. The weighting is a function of a geometric distance between vertices. The direction of traversal is limited towards neighboring vertices where a color mismatch is a color difference larger than the threshold value. The color of a neighboring vertex is rejected if the vertex normals differ from by a large angle. The weighted average of colors of the neighboring vertices is also rejected if the given vertex lies in a region where the color match/mismatch ratio is low at the end of the traversal.

  • Patent number: 9818232
    Abstract: Methods and systems for correcting depth irregularities in a three-dimensional scanned model. In particular, one or more embodiments obtain depth data and color data for an object using a depth scanner and a color scanner, respectively. One or more embodiments identify, based on edge information in the color data, regions that have no depth data that are part of the object. One or more embodiments then correct the depth frame by assigning depth data to the identified regions based on a gradient of depth data from areas near the identified regions. The methods and systems use the corrected depth data to generate a corrected three-dimensional model of the object.
