20210295565, Sep 23, 2021

Filed:

Jun 6, 2021

Appl. No.:

17/340081

Inventors:

- West Lafayette IN, US
Tyler Bell - Lafayette IN, US

Assignee:

Purdue Research Foundation - West Lafayette IN

International Classification:

G06T 9/00
G06T 7/90

Abstract:

A method for generating encoded depth data includes receiving digital fringe projection (DFP) data corresponding to a three-dimensional structure of a physical object, and generating first and second fringe encodings for a first predetermined wavelength based on the DFP data at a first coordinate. The method further includes generating third and fourth fringe encodings for a second predetermined wavelength based on the DFP data at the first coordinate, the second wavelength being longer than the first wavelength, and generating a combined fringe encoding based on the third fringe encoding and the fourth fringe encoding. The method further includes storing the first, second, and combined fringe encoding data in a pixel of two-dimensional image data at a pixel coordinate in the two-dimensional image data corresponding to the first coordinate.

Abstract:

A method of processing data includes obtaining, by an encoding medium, the data of at least one of a geometry information or a texture information of a target. The method additionally includes converting, by the encoding medium, the geometry information into a plurality of periodical functions. Additionally, converting, by the encoding medium, the texture information into a second 2-D representation. Further, the method includes converting, by the encoding medium, each periodical function of the plurality of periodical functions and the second 2-D representation into an image. Moreover, the method includes decoding, by a decoding medium, the image into a 3-D representation using a transformation.

International Classification:

A61F 2/38
A61F 2/30

Abstract:

Methods, techniques and apparatuses are disclosed including exemplary methods of performing a knee arthroplasty of the tibia. One exemplary method can include determining at least a depth of a distal fixation feature of a tibial implant, and forming a metaphyseal recess in a proximal portion of the tibia. The recess can be configured to receive the distal fixation feature therein and can be sized to exceed at least the depth of the distal fixation feature such that when a distal surface of the tibial implant contacts a proximal surface of the proximal portion of the tibia and the distal fixation feature is received in the metaphyseal recess, a gap remains between the distal fixation feature and one or more surfaces that form a portion of the metaphyseal recess.
