    摘要: Systems, methods, and devices are used to match images. Points of interest from a first image are identified for matching to a second image. In response to the identified points of interest, regions and features can be identified and used to match the points of interest to a corresponding second image or second series of images. Regions can be used to match the points of interest when regions of the first image are matched to the second image with high confidence scores, for example above a threshold. Features of the first image can be matched to the second image, and these matched features may be used to match the points of interest to the second image, for example when the confidence scores for the regions are below the threshold value. Constraint can be used to evaluate the matched points of interest, for example by excluding bad points.

    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.
