METHOD AND SYSTEM FOR SURGICAL TOOL LOCALIZATION DURING ANATOMICAL SURGERY

摘要

To localize surgical tools during anatomical surgery, an image-capturing device (218) captures images of a surgical site, and a processor (202) determines (906) physical characteristics surgical tools present in the images (406b, e.g.) based on color and/or geometric constraints. 2D masks of the surgical tools are detected (908), based on the physical characteristics of the surgical tools. Further, poses of the surgical tools are estimated (912), when the 2D masks of the surgical tools are occluded at tips and/or ends of the surgical tools.
