Abstract

A system for measuring distances within a surgical site includes a camera positionable to capture 3D image data corresponding to a treatment site. Using the image data, the system determines the relative 3D positions of identified measurement points at the treatment site captured in the images, and it estimates or determines the distance between the measurement points. Output is generated communicating the measured distances to the user. The measurement taken follows the 3D topography of the tissue positioned between the measurement points.
