Methods and systems for robotic instrument tool tracking with adaptive fusion of kinematics information and image information
First Claim
1. A method for a robotic system, the method comprising:
- generating kinematics information for a robotic instrument within a field of view of a camera;
capturing image information in the field of view of the camera; and
adaptively fusing the kinematics information and the image information together to determine pose information of the robotic instrument;
wherein the adaptive fusing of the kinematics information and the image information together includes synthesizing an image of a model of the robotic instrument in response to the kinematics information, matching the image of the model to the image information to generate match results, filtering the match results, and forming a plurality of states of the pose information for the robotic instrument in response to the filtered match results and kinematics information.

Abstract
In one embodiment of the invention, a method for a robotic system is disclosed to track one or more robotic instruments. The method includes generating kinematics information for the robotic instrument within a field of view of a camera; capturing image information in the field of view of the camera; and adaptively fusing the kinematics information and the image information together to determine pose information of the robotic instrument. Additionally disclosed is a robotic medical system with a tool tracking sub-system. The tool tracking sub-system receives raw kinematics information and video image information of the robotic instrument to generate corrected kinematics information for the robotic instrument by adaptively fusing the raw kinematics information and the video image information together.
