Rendering tool information as graphic overlays on displayed images of tools
First Claim
Patent Images
1. A robotic system comprising:
- a tool having a working end, the working end adapted to physically interact with an object;
a manipulator coupled to the tool for robotic manipulation of the tool;
a camera spatially disposed relative to the tool so that the camera captures an image of the working end of the tool from a perspective of an image reference frame;
a display coupled to the camera for displaying the image of the working end of the tool; and
a processor programmed to render information of the tool over the image of the working end of the tool which was captured by the camera and is being displayed on the display by;
determining a pose of the tool in the image reference frame;
registering the information of the tool with a designated place on the working end of the tool in the image reference frame by using the pose of the tool in the image reference frame; and
rendering the information of the tool over the designated place on the working end of the tool in the image of the working end of the tool being displayed on the display after registering the information of the tool with the designated place on the working end of the tool, so that the entire information of the tool appears as a decal that is rendered over the working end of the tool in the image of the working end of the tool being displayed on the display by bending the decal to conform in shape and be applied to an outer surface of the tool at the designated place.

Abstract
An operator telerobotically controls tools to perform a procedure on an object at a work site while viewing real-time images of the work site on a display. Tool information is provided in the operator'"'"'s current gaze area on the display by rendering the tool information over the tool so as not to obscure objects being worked on at the time by the tool nor to require eyes of the user to refocus when looking at the tool information and the image of the tool on a stereo viewer.

15. A method, implemented in a robotic system, the robotic system comprising:
- a tool having a working end;
the working end adapted to physically interact with an object;
a manipulator coupled to the tool for robotic manipulation of the tool;
a camera spatially disposed relative to the tool so that the camera captures an image of the working end of the tool from a perspective of an image reference frame; and
a display coupled to the camera for displaying the image of the working end of the tool;the method comprising; rendering information of the tool over the image of the working end of the tool which was captured by the camera and is being displayed on the display by; determining a pose of the tool in the image reference frame; registering the information of the tool with a designated place on the working end of the tool in the image reference frame by using the pose of the tool in the image reference frame; and rendering the information of the tool over the designated place on the working end of the tool in the image of the working end of the tool being displayed on the display after registering the information of the tool with the designated place on the working end of the tool, so that the entire information of the tool appears as a decal that is rendered over the working end of the tool in the image of the working end of the tool being displayed on the display by bending the decal to conform in shape and be applied to an outer shape of the tool at the designated place. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
