Abstract

One aspect of this disclosure is a method comprising: receiving, from a camera, a video feed depicting a pair of feet and a scaling object; capturing, with the camera, images of the feet and the scaling object based on the video feed; identifying foot features in each captured image; determining camera positions for each captured image by triangulating the foot features; generating a point cloud in a three-dimensional space by positioning each foot feature in the three-dimensional space based on the camera positions; scaling the point cloud based on the scaling object; segmenting the point cloud into at least a right-foot cluster and a left-foot cluster; fitting a first three-dimensional morphable model to the right-foot cluster according to first foot parameters; and fitting a second three-dimensional morphable model to the left-foot cluster according to second foot parameters. Related systems, apparatus, and methods also are described.

Dependent claims

A computer-implemented method comprising:

receiving, from a camera, a video feed depicting a pair of feet and a scaling object;
capturing, with the camera, images of the feet and the scaling object based on the video feed;
identifying foot features in each captured image;
determining camera positions for each captured image by triangulating the foot features;
generating a point cloud in a three-dimensional space by positioning each foot feature in the three-dimensional space based on the camera positions;
scaling the point cloud based on the scaling object;
segmenting the point cloud into at least a right-foot cluster and a left-foot cluster;
fitting a first three-dimensional morphable model to the right-foot cluster according to first foot parameters by a first process comprising:
(i) placing the first three-dimensional morphable model over the right-foot cluster;
(ii) modifying the first three-dimensional morphable model without deformation to fit the right-foot cluster;
and
(iii) modifying the first three-dimensional morphable model with deformation by iteratively adjusting the first foot parameters individually or in combination to reduce an error value between the first three-dimensional morphable model and the right-foot cluster;
fitting a second three-dimensional morphable model to the left-foot cluster according to second foot parameters by a second process comprising:
(i) placing the second three-dimensional morphable model over the left-foot cluster;
(ii) modifying the second three-dimensional morphable model without deformation to fit the left-foot cluster;
and
(iii) modifying the second three-dimensional morphable model with deformation by iteratively adjusting the second foot parameters individually or in combination to reduce an error value between the second three-dimensional morphable model and the left-foot cluster;
and
outputting data comprising right-foot data and left-foot data.
