Image-based surface tracking

摘要

A method of image-tracking by using an image capturing device (12). The method comprises: performing an image-capture of a scene (54) by using an image capturing device; and tracking movement (62) of the image capturing device (12) by analyzing a set of images by using an image processing algorithm (64).

1. A method of image-based positioning comprising:
(A) performing an image-capture of a scene by using an image capturing device; wherein a set of captured images data and a set of scene depth data is created; (B) performing a rigid global transformation of said set of captured images data and said set of scene depth data into a set of 6-coordinate data; wherein said set of 6-coordinate data represents movement of said image capturing device; and (C) determining the position coordinates of said image capturing device by using an image processing algorithm; said image processing algorithm including a global optical flow; said image processing algorithm including at least one step of parametrizing said global optical flow with said image capturing device.
