Patents by Inventor Vasiliy Evgenyevich Buharin

Vasiliy Evgenyevich Buharin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11857153
    Abstract: Systems and methods for multi-modal sensing of three-dimensional position information of the surface of an object are disclosed. In particular, multiple visualization modalities are each used to collect distinctive positional information of a surface of an object. Each of the computed positional information is combined using weighting factors to compute a final, weighted three-dimensional position. In various embodiments, a first depth may be recorded using fiducial markers, a second depth may be recorded using a structured light pattern, and a third depth may be recorded using a light-field camera. Weighting factors may be applied to each of the recorded depths and a final, weighted depth may be computed.

  • Publication number: 20220020160
    Abstract: User interface elements for orientation of remote camera during surgery are provided. In various embodiments, an image of an interior of a body cavity of a patient is received from one or more camera located at a distal end of an endoscopic tool. Position information and/or orientation information of the camera is received. A reference view indicating a field of view of the camera(s) on an anatomical model is generated based on the position information and/or orientation information. The reference view is displayed in combination with the image to a user.

  • Publication number: 20210354285
    Abstract: Systems and methods for mechanical coupling and calibration of two fixed-base robotic arms are disclosed. In particular, a first robotic arm is affixed to a first base at a proximal end and has a first coupling at a distal end and a second robotic arm is affixed to a second base at a proximal end and has a second coupling at a distal end. The first coupling is releasably coupled to a second coupling via a locking mechanism to prevent relative motion between the first and second couplings. Three-dimensional positional data is collected for the distal ends of the first robotic arm and the second robotic arm in one or more positions. A calibration value is determined from the three-dimensional positional data. The calibration value may be a calibration matrix determined by a least mean squares method.
