1. A surgical system, comprising:
a localizer configured to generate localizer data associated with a surgical object;
a vision device configured to generate image data associated with the surgical object and an environment of the surgical object within a field-of-view of the vision device; and
one or more controllers configured to:
associate a first virtual object with the surgical object;
determine a pose of the first virtual object based on the localizer data;
merge the image data and the localizer data in a common coordinate system to identify data points in the image data that have coordinates located outside of the first virtual object; and
associate a second virtual object with the identified data points.
