Technologies for determining the spatial orientation of input imagery for use in an orthopaedic surgical procedure

One or more non-transitory, machine-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause a computer to:

• determine first candidate values indicative of an orientation of an anatomical object in each of a plurality of two-dimensional images showing a plurality of bones of a human joint;
• produce, as a function of the plurality of two-dimensional images and the candidate values, a first candidate three-dimensional model of the anatomical object;
• determine a first score indicative of an accuracy of the first candidate three-dimensional model;
• determine, in response to the first score not satisfying a threshold, second candidate values indicative of the orientation of the anatomical object in each of the plurality of two-dimensional images;
• produce, as a function of the plurality of two-dimensional images and the second candidate values, a second candidate three-dimensional model of the anatomical object;
• determine a second score indicative of an accuracy of the second candidate three-dimensional model;
• determine, in response to the second score not satisfying the threshold, third candidate values indicative of the orientation of the anatomical object in each of the plurality of two-dimensional images;
• and
• produce, as a function of the plurality of two-dimensional images and the third candidate values, a third candidate three-dimensional model of the anatomical object.

A method comprising:

• determining, by a computer, first candidate values indicative of an orientation of an anatomical object in each of a plurality of two-dimensional images showing a plurality of bones of a human joint;
• producing, by the computer and as a function of the plurality of two-dimensional images and the candidate values, a first candidate three-dimensional model of the anatomical object;
• determining, by the computer, a first score indicative of an accuracy of the first candidate three-dimensional model;
• determining, by the computer and in response to the first score not satisfying a threshold, second candidate values indicative of the orientation of the anatomical object in each of the plurality of two-dimensional images;
• producing, by the computer and as a function of the plurality of two-dimensional images and the second candidate values, a second candidate three-dimensional model of the anatomical object;
• determining, by the computer, a second score indicative of an accuracy of the second candidate three-dimensional model;
• determining, by the computer, in response to the second score not satisfying the threshold, third candidate values indicative of the orientation of the anatomical object in each of the plurality of two-dimensional images;
• and
• producing, by the computer and as a function of the plurality of two-dimensional images and the third candidate values, a third candidate three-dimensional model of the anatomical object.
