Quantitative three-dimensional imaging of surgical scenes from multiport perspectives

摘要

A system is provided that includes a quantitative three-dimensional (Q3D) endoscope that is inserted through a first port providing access to a body cavity to a first position at which a first 3D image of a first portion of an anatomical structure is captured from a perspective of said endoscope. A first Q3D model is produced based upon the captured first image. The endoscope is inserted through a second port providing access to the body cavity to a second position at which a second image of a second portion of the anatomical structure is captured. A second quantitative Q3D model is produced based upon the captured second image. The first Q3D model and the second Q3D model are combined together to produce an expanded Q3D model of the anatomical structure. The expanded Q3D model can be stored for further manipulation or can be displayed in 3D.
