Fiducial marker design and detection for locating surgical instrument in images

摘要

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.
