Using a combination of 2D and 3D image data to determine hand features information |
摘要 |
A method of determining hand features information using both two dimensional (2D) image data and three dimensional (3D) image data is described. In one implementation, a method includes: receiving a 2D image frame; receiving 3D image data corresponding to the 2D image frame; using the 3D image data corresponding to the 2D image frame, transforming the 2D image frame; and using the 3D image data corresponding to the 2D image frame, scaling the 2D image frame, where the transforming and scaling results in a normalized 2D image frame, where the normalized 2D image frame is a scaled and transformed version of the 2D image frame, and where the scaling and transforming is performed using a computer. |

1. A method comprising:
receiving a two dimensional (2D) image frame; receiving three dimensional (3D) image data corresponding to the 2D image frame; using the 3D image data corresponding to the 2D image frame, rotating and scaling the 2D image frame, wherein the rotating and scaling results in a normalized 2D image frame, wherein the normalized 2D image frame is a scaled and rotated version of the 2D image frame, further wherein the scaling and rotating is performed using a computer; determining hand features information in two dimensions of a hand in the normalized 2D image frame; and mapping the hand features information in two dimensions to hand features information in three dimensions. |
