Methods and system for performing 3-D tool tracking by fusion of sensor and/or camera derived data during minimally invasive robotic surgery

Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

Motion event recognition system and method

Enables recognition of events within motion data including but not limited to motion capture data obtained from portable wireless motion capture elements such as visual markers and sensors, radio frequency identification tags and motion sensors within mobile device computer systems, or calculated based on analyzed movement associated with the same user, other user, historical user or group of users. Provides low power transmission of events. Greatly reduces storage for events such as a shot, move or swing of a player, a concussion of a player, boxer, rider or driver, or a heat stroke, hypothermia, seizure, asthma attack, epileptic attack. Events may be correlated with image(s) as captured from internal / external camera(s) or nanny cam, for example to enable saving video of the event, such as the first steps of a child, violent shaking events, sporting, military or other motion events including concussions, or falling events associated with an elderly person.

Method and system for finding a tool center point for a robot using an external camera

Disclosed is a method and system for finding a relationship between a tool-frame of a tool attached at a wrist of a robot and robot kinematics of the robot using an external camera. The position and orientation of the wrist of the robot define a wrist-frame for the robot that is known. The relationship of the tool-frame and / or the Tool Center Point (TCP) of the tool is initially unknown. For an embodiment, the camera captures an image of the tool. An appropriate point on the image is designated as the TCP of the tool. The robot is moved such that the wrist is placed into a plurality of poses. Each pose of the plurality of poses is constrained such that the TCP point on the image falls within a specified geometric constraint (e.g. a point or a line). A TCP of the tool relative to the wrist frame of the robot is calculated as a function of the specified geometric constraint and as a function of the position and orientation of the wrist for each pose of the plurality of poses. An embodiment may define the tool-frame relative to the wrist frame as the calculated TCP relative to the wrist frame. Other embodiments may further refine the calibration of the tool-frame to account for tool orientation and possibly for a tool operation direction. An embodiment may calibrate the camera using a simplified extrinsic technique that obtains the extrinsic parameters of the calibration, but not other calibration parameters.
