Avatar construction using depth camera
First Claim
1. A method for constructing an avatar of a human subject, the method comprising:
- acquiring a depth map of the human subject;
obtaining a virtual skeleton of the human subject based on the depth map;
harvesting from the virtual skeleton a set of characteristic metrics corresponding to distances between predetermined points of the virtual skeleton;
providing the characteristic metrics as input to an algorithm trained using machine learning, the algorithm having been trained using at least one single human being in a range of poses and a range of human beings in a single pose, to output a virtual body mesh as a function of the characteristic metrics;
refining the virtual body mesh by varying the characteristic metrics to decrease distance between points on the depth map and corresponding points of the virtual body mesh;
constructing a virtual head mesh, distinct from the virtual body mesh, with facial features resembling those of the human subject; and
connecting the virtual body mesh to the virtual head mesh.

Abstract
A method for constructing an avatar of a human subject includes acquiring a depth map of the subject, obtaining a virtual skeleton of the subject based on the depth map, and harvesting from the virtual skeleton a set of characteristic metrics. Such metrics correspond to distances between predetermined points of the virtual skeleton. In this example method, the characteristic metrics are provided as input to an algorithm trained using machine learning. The algorithm may be trained using a human model in a range of poses, and a range of human models in a single pose, to output a virtual body mesh as a function of the characteristic metrics. The method also includes constructing a virtual head mesh distinct from the virtual body mesh, with facial features resembling those of the subject, and connecting the virtual body mesh to the virtual head mesh.
