Methods and systems for robotic instrument tool tracking with adaptive fusion of kinematics information and image information
Wenyi Zhao,Christopher J. Hasser,William C. Nowlin,Brian D. Hoffman +3 more
- 30 Sep 2007
TL;DR: In this article, a method for a robotic system to track one or more robotic instruments is described, which 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 kinematic information and the image information together to determine pose information of the robotic instruments.
