Creating a synthetic model with organic veracity

摘要

A method of creating a real time synthetic model tracking a dynamic physical entity, comprising:
a) Receiving multiple points extracted from a sequence of a three dimensional (3D) information depicting a dynamic physical entity, each point is associated with position and photometric information.
b) Identifying, within the multiply of points, a cloud point which includes multiple entity representative points which portray a surface of the dynamic physical entity.
c) Generating in real time a points-surface for a synthetic model by creating spatial presentation of the entity representative points through calculation of principal curvatures for each entity representative point according to the respective position information.
d) Generating in real time a continuous surface for the synthetic model by texturing ellipsoidal shapes created for each entity representative point according to the respective photometric information.
e) Tracking in real time motion of the dynamic physical entity by adjusting the points-surface and the continuous surface through a plurality of iterations wherein in each iteration steps a)-d) are performed.
