10. A surgical system comprising:
an arthroscope configured to capture images of a target site having a ROI with a varying dimension associated therewith;
a tracking system being separate from the arthroscope and being configured to track a pose of the arthroscope; and
one or more controllers coupled to the arthroscope and the tracking system and being configured to:
acquire images of the target site captured by the arthroscope;
determine, with the tracking system, poses at which the images are captured by the arthroscope;
analyze the images and the poses at which the images are captured by the arthroscope to obtain points related to the ROI; and
implement a stereo motion procedure with respect to the points of the ROI to determine the varying dimension of the ROI at each of a plurality of times.
