IMAGE SEGMENTATION WITH KINEMATIC DATA IN A ROBOTIC SURGICAL SYSTEM
A system makes use of kinematic data from a robotic manipulator to aid in segmenting images of a robotically maneuvered surgical instrument at an operative site. A camera is positioned to capture image data of the surgical instrument at the surgical site. At least one processor receives the image data as well as kinematic data from the robotic manipulator. The kinematic data is used to define regions of interest in the images, and image segmentation is then carried out at the regions of interest to identify the surgical instruments in the image data.
1 . A system for segmenting images of surgical instruments from image data, comprising:
at least one manipulator holding a surgical instrument, the surgical instrument positionable at a surgical site in a body cavity;
a camera positionable to capture image data of the surgical instrument at the surgical site;
at least one processor is configured for receiving the image data and kinematic data from the robotic manipulators, the processor including a memory storing instructions that, when executed, use the kinematic data to define regions of interest for image segmentation, and then perform image segmentation at the regions of interest to identify the surgical instruments in the image data.
