Sony patents method to track 3D model motion using color and position data
Sony has been granted a patent for a system that calculates how much a 3D model moves between video frames. It combines color data and 3D coordinates from different points to estimate movement more accurately.
In the filing’s own words
It is desirable to provide a technology capable of more accurately estimating a motion of a three-dimensional model between a plurality of frames. Provided is an information processing apparatus including a movement amount calculation unit that calculates a movement amount associated with a first vertex included in a first frame on the basis of statistical processing according to color information associated with the first vertex, color information associated with a second vertex included in a second frame after the first frame, three-dimensional coordinates associated with the first vertex, and three-dimensional coordinates associated with the second vertex.
What exactly they claim (claim 1)
1. An information processing apparatus comprising: circuitry configured to calculate a movement amount associated with a first vertex included in a first frame based on statistical processing according to color information associated with the first vertex, color information associated with a second vertex included in a second frame after the first frame, three-dimensional coordinates associated with the first vertex, and three-dimensional coordinates associated with the second vertex, and extract at least one surface having the three-dimensional coordinates whose distance from the three-dimensional coordinates of the first surface is smaller than a first threshold value, from among a plurality of surfaces included in the second frame.
