    摘要: Image-based control systems and methods automate the adjustment of medical devices. An image based-control system for an endoscope can include, in addition to the endoscope, a processing system and an actuator. The processing system can receive an image from an image capture device of the endoscope. Based on coordinates of a lumen in the image, the processing system can instruct the actuator to reorient the capture device to direct the capture device toward the lumen. The actuator can be coupled to a manual controller of the endoscope, such that the actuator can reorient the capture device via the manual controller. An image-based control method can include receiving an image from the capture device of the endoscope; identifying coordinates of a lumen in the image; mapping such coordinates to a physical position of the lumen relative to the capture device; and instructing an actuator to adjust an orientation of the endoscope.

    摘要: An apparatus and method for enabling an uncalibrated, model independent controller for a mechanical system using a dynamic quasi-Newton algorithm which incorporates velocity components of any moving system parameter(s) is provided. In the preferred embodiment, tracking of a moving target by a robot having multiple degrees of freedom is achieved using an uncalibrated model independent visual servo control. Model independent visual servo control is defined as using visual feedback to control a robot's servomotors without a precisely calibrated kinematic robot model or camera model. A processor updates a Jacobian and a controller provides control signals such that the robot's end effector is directed to a desired location relative to a target on a workpiece.
