Systems and methods for measuring a distance using a stereoscopic endoscope

A measurement system comprising:

• a stereoscopic endoscope configured to be located at a surgical area associated with a patient, the stereoscopic endoscope including
• a first camera configured to capture a first image from a first vantage point, and
• a second camera configured to capture a second image from a second vantage point that is stereoscopic to the first vantage point;
• a display screen configured to display the first image;
• a user interface associated with the display screen and allowing a user of the measurement system to designate, from a display of the first image on the display screen, a user-selected two-dimensional (“2D”) endpoint corresponding to a feature within the surgical area as represented in the first image;
• and
• at least one physical computing device communicatively coupled to the stereoscopic endoscope, the display screen, and the user interface, and configured to
• identify, based on the user-selected 2D endpoint, a matched 2D endpoint corresponding to the feature as represented in the second image,
• define, based on the user-selected and matched 2D endpoints, a three-dimensional (“3D”) endpoint corresponding to the feature within the surgical area, and
• determine a distance from the 3D endpoint to an additional 3D endpoint corresponding to an additional feature within the surgical area.

A method comprising:

• accessing, by a measurement system, a first image captured from a first vantage point by a first camera included within a stereoscopic endoscope located at a surgical area associated with a patient;
• accessing, by the measurement system, a second image captured from a second vantage point by a second camera included within the stereoscopic endoscope, the second vantage point stereoscopic to the first vantage point;
• receiving, by the measurement system from a user of the measurement system, user input designating a user-selected two-dimensional (“2D”) endpoint corresponding to a feature within the surgical area as represented in the first image;
• identifying, by the measurement system based on the user-selected 2D endpoint, a matched 2D endpoint corresponding to the feature as represented in the second image;
• defining, by the measurement system based on the user-selected and matched 2D endpoints, a three-dimensional (“3D”) endpoint corresponding to the feature within the surgical area;
• and
• determining, by the measurement system, a distance from the 3D endpoint to an additional 3D endpoint corresponding to an additional feature within the surgical area.
