Abstract
Official abstract text for this publication.
The present disclosure relates to systems, methods, and tools for tool tracking using image-derived data from one or more tool-located reference features. A method includes: capturing a first image of a tool that includes multiple features that define a first marker, where at least one of the features of the first marker includes an identification feature; determining a position for the first marker by processing the first image; determining an identification for the first marker by using the at least one identification feature by processing the first image; and determining a tool state for the tool by using the position and the identification of the first marker.
First claim
Opening claim text (preview).
What is claimed is: 1. A method implemented by a processor, the method comprising: receiving, at the processor, information of an image of a surgical tool that was captured by an image capture device, wherein the surgical tool has a first marker that includes a first identification feature which includes a first plurality of dots, the first plurality of dots arranged in a first pattern of dots which indicates values of first data bits and a value or values of at least one first er…
