Augmented reality guided instrument positioning with modulated guiding graphics
First Claim
Patent Images
1. A method for augmented reality guided instrument positioning, comprising the steps of:
- displaying a real view of an environment including an instrument;
determining a preferred path for positioning of said instrument;
marking the preferred path with a graphics guide;
augmenting the real view with a rendering of the graphics guide such that at least one portion of the graphics guide is transparent with respect to other portions of the graphics guide to provide a substantially unobstructed view through the at least one portion of the graphics guide to at least a portion of the instrument to facilitate alignment of the real instrument with the virtual guide, the transparency of at least one portion of the guide being varied at redefined time intervals;
aligning the instrument with the graphics guide so that the instrument appears in a same location as the graphics guide in the augmented view thereby creating a mutual spatial relationship between the real instrument and the virtual guide, and when properly aligned, at least a portion of the instrument is visible through the at least one transparent portion of the graphics guide; and
inserting the instrument in the graphics guide.

Abstract
There is provided a method for augmented reality guided instrument positioning. A graphics guide is determined for positioning an instrument. The graphics guide is rendered such that an appearance of at least one portion of the graphics guide is modulated with respect to at least one of space and time.

12. An apparatus for augmented reality guided instrument positioning, comprising:
-
a video camera providing a real view of an environment including an instrument; a graphics guide generator for identifying a preferred path for positioning said instrument and generating a graphics guide for marking the preferred path; and a rendering device for augmenting the real view with a rendering of the graphics guide such that at least one portion of the graphics guide is transparent with respect to other portions of the graphics guide to provide a substantially unobstructed view through the at least one portion of the graphics guide to at least a portion of the instrument to facilitate alignment of the real instrument with the virtual guide, the transparency of at least one portion of the guide being varied at predefined time intervals; an alignment device for aligning the instrument to the graphics guide so that the instrument appears in a same location as the graphics guide in the augmented view thereby creating a mutual spatial relationship between the real instrument and the virtual guide, and when properly aligned, at least a portion of the instrument is visible through the at least one transparent portion of the graphics guide; and an insertion device for inserting the instrument in the graphics guide. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method for augmented reality guided instrument positioning, comprising the steps of:
-
displaying a real camera view of an environment including an instrument; determining a preferred path of the instrument in the environment; marking the preferred path with a graphics guide, the graphics guide indicating a predetermined position to which the instrument is alignable; and augmenting the real camera view with a rendering of a virtual view of the graphics guide such that at least one portion of the graphics guide is transparent with respect to other portions of the graphics guide to provide a substantially unobstructed view through the at least one portion of the graphics guide to at least a portion of the instrument to facilitate alignment of the real instrument with the virtual guide, the transparency of at least one portion of the guide being varied at predefined time intervals; aligning the instrument to the graphics guide so that the instrument appears in a same location as the graphics guide in the augmented view thereby creating a mutual spatial relationship between the real instrument and the virtual guide, and when properly aligned, the instrument is visible through the at least one transparent portion of the graphics guide; and inserting the instrument in the graphics guide.
