Three-Dimensional Sensor With Counterposed Channels

View page
US Patent:
20200124407, Apr 23, 2020
Filed:
Oct 17, 2019
Appl. No.:
16/655687
Inventors:
- Golden Valley MN, US
Evan J. Ribnick - St. Louis Park MN, US
Carl E. Haugan - St. Paul MN, US
Eric P. Rudd - Hopkins MN, US
Timothy A. Skunes - Mahtomedi MN, US
International Classification:
G01B 11/25
H04N 5/372
G01B 11/30
Abstract:
An optical phase profilometry system includes a first operative coaxial camera-projector pair aligned at a first angle relative to a target surface that projects a first illumination on the target surface and a second operative coaxial camera-projector pair aligned at a second angle relative to the target surface that projects a second illumination on the target surface. Wherein the first and second angles are equal and opposite to one another relative to the target surface such that the second operative coaxial camera-projector pair is configured to capture a first reflection from the first illumination and the first operative coaxial camera-projector pair is configured to capture a second reflection from the second illumination. The optical phase profilometry system further includes a controller configured to, based on the captured first and second reflections, generate a first and second estimation of the target surface and combine them to generate a dimensional profile of the target surface.

US Patent:
20200124410, Apr 23, 2020
Filed:
Oct 17, 2019
Appl. No.:
16/655674
Inventors:
- Golden Valley MN, US
Evan J. Ribnick - St. Louis Park MN, US
Carl E. Haugan - St. Paul MN, US
Eric P. Rudd - Hopkins MN, US
International Classification:
G01B 11/30
G01B 11/25
H04N 5/372
Abstract:
A method of determining dimensional information of a target surface includes generating a first point cloud corresponding to a first plurality of reconstructed surface points of the target surface generated by a first imaging system-illumination source pair of a phase profilometry system; generating a second point cloud corresponding to a second plurality of reconstructed surface points of the target surface generated by a second imaging system-illumination source pair of the phase profilometry system; generating an initial estimate of the target surface based on the first and second point clouds; and refining the initial surface estimate using positions of the first and second point clouds and geometry of the first and second imaging system-illumination source pairs to generate a final point cloud.

US Patent:
20190114374, Apr 18, 2019
Filed:
Dec 12, 2018
Appl. No.:
16/217094
Inventors:
- St. Paul MN, US
Evan J. Ribnick - St. Louis Park MN, US
Ravishankar Sivalingam - Woodbury MN, US
Shannon D. Scott - Hudson WI, US
Golshan Golnari - Minneapolis MN, US
Aya Eid - St. Paul MN, US
International Classification:
G06F 17/50
A61C 13/00
A61C 9/00
A61C 7/00
Abstract:
Methods for aligning a digital 3D model of teeth represented by a 3D mesh to a desired orientation within a 3D coordinate system. The method includes receiving the 3D mesh in random alignment and changing an orientation of the 3D mesh to align the digital 3D model of teeth with a desired axis in the 3D coordinate system. The methods can also detect a gum line in the digital 3D model to remove the gingiva from the model.

Population-Based Surface Mesh Reconstruction

View page
US Patent:
20190043255, Feb 7, 2019
Filed:
Feb 3, 2017
Appl. No.:
16/075072
Inventors:
- St. Paul MN, US
Robert W. Shannon - Stillwater MN, US
Evan J. Ribnick - St. Louis Park MN, US
Ravishankar Sivalingam - San Jose CA, US
International Classification:
G06T 17/20
Abstract:
Reconstructed surface meshes can be generated based on a plurality of received surface meshes. Each surface mesh can include vertices and faces representing an object. The received surface meshes can be assigned to one of a plurality of groups, and a region of interest of each surface mesh within each group can be aligned. The reconstructed surface meshes can be generated based on the aligned regions of interest for each group.

Automatic Alignment And Orientation Of Digital 3D Dental Arch Pairs

View page
US Patent:
20180333231, Nov 22, 2018
Filed:
May 17, 2017
Appl. No.:
15/597479
Inventors:
- St. Paul MN, US
Benjamin D. Zimmer - Maplewood MN, US
Alexandra R. Cunliffe - St. Paul MN, US
Mojtaba K. Elyaderani - Minneapolis MN, US
Arash Sangari - Woodbury MN, US
Evan J. Ribnick - St. Louis Park MN, US
International Classification:
A61C 9/00
G06T 19/20
Abstract:
A method for aligning digital 3D models of dental arch pairs, including a mandible and maxilla, to bring them into bite alignment. The method estimates representative planes for the mandible and maxilla 3D models and transforms the models such that the representative planes are each aligned with their respective coordinate systems and shown in a horizontal view. The method also transforms the models such that the mandible and maxilla are each aligned with a same coordinate system and shown in a front view. The digital 3D models are then brought into bite alignment such that the mandible is in occlusion with the maxilla or within a distance near to occlusion. The digital models of the bite-aligned arch pairs can also be transformed or rotated to be shown centered in a front view.

US Patent:
20180300877, Oct 18, 2018
Filed:
Jun 26, 2018
Appl. No.:
16/018115
Inventors:
- St. Paul MN, US
Ravishankar Sivalingam - San Mateo CA, US
Evan J. Ribnick - St. Louis Park MN, US
Kevin S. Xu - Toledo OH, US
International Classification:
G06T 7/00

G06K 9/66
G06K 9/00
A61C 9/00

G06K 9/46
Abstract:
Methods for recognizing or identifying tooth types using digital 3D models of teeth. The methods include receiving a segmented digital 3D model of teeth and selecting a digital 3D model of a tooth from the segmented digital 3D model. An aggregation of the plurality of distinct features of the tooth is computed to generate a single feature describing the digital 3D model of the tooth. A type of the tooth is identified based upon the aggregation, which can include comparing the aggregation with features corresponding with known tooth types. The methods also include identifying a type of tooth, without segmenting it from an arch, based upon tooth widths and a location of the tooth within the arch.

Synchronization And Animation Of Views Showing Digital 3D Models Of Teeth

View page
US Patent:
20170236327, Aug 17, 2017
Filed:
Feb 12, 2016
Appl. No.:
15/042424
Inventors:
- St. Paul MN, US
Evan J. Ribnick - St. Louis Park MN, US
Matthew R. Cruikshank - St. Paul MN, US
Lindsay Labahn - St. Paul MN, US
Judy J. Ma - Woodbury MN, US
International Classification:
G06T 17/10
G06F 3/0481
G06T 13/20
G06T 19/20
Abstract:
Systems and methods for displaying synchronized views and animations of digital 3D models of a person's intra-oral structure such as teeth. Two digital 3D models obtained from scans at different times are displayed in side-by-side views and synchronized via registration of the two scans or corresponding models. A user's control input to one displayed model causes the same manipulation of both models since they are registered. The two digital 3D models can also be displayed in an animation mode where the first model slowly morphs into the second model to illustrate changes in the intra-oral structure over time.

Detecting Tooth Wear Using Intra-Oral 3D Scans

US Patent:
20170178327, Jun 22, 2017
Filed:
Mar 3, 2017
Appl. No.:
15/448978
Inventors:
- St. Paul MN, US
Evan J. Ribnick - St. Louis Park MN, US
Ravishankar Sivalingam - Woodbury MN, US
Aya Eid - St. Paul MN, US
Theresa M. Meyer - Osceola WI, US
Golshan Golnari - Minneapolis MN, US
Anthony J. Sabelli - Woodbury MN, US
International Classification:
G06T 7/00
G06T 15/08
G06T 13/20
G06T 7/11
G06T 19/20
Abstract:
A method for detecting tooth wear using digital 3D models of teeth taken at different times. The digital 3D models of teeth are segmented to identify individual teeth within the digital 3D model. The segmentation includes performing a first segmentation method that over segments at least some of the teeth within the model and a second segmentation method that classifies points within the model as being either on an interior of a tooth or on a boundary between teeth. The results of the first and second segmentation methods are combined to generate segmented digital 3D models. The segmented digital 3D models of teeth are compared to detect tooth wear by determining differences between the segmented models, where the differences relate to the same tooth to detect wear on the tooth over time.
