Abstract: A measurement system accesses first and second images captured respectively from first and second vantage points by first and second cameras included within a stereoscopic endo scope located at a surgical area associated with a patient. The measurement system receives user input designating a user-selected two-dimensional (“2D”) endpoint corresponding to a feature within the surgical area as represented in the first image, and identifies, based on the user-selected 2D endpoint, a matched 2D endpoint corresponding to the feature as represented in the second image. Based on the user-selected and matched 2D endpoints, the measurement system defines a three-dimensional (“3D”) endpoint corresponding to the feature within the surgical area. The measurement system then determines a distance from the 3D endpoint to an additional 3D endpoint corresponding to an additional feature within the surgical area. Corresponding systems and methods are also described.

Abstract: An exemplary processing system of a computer-assisted surgical system identifies an object in a surgical space, accesses a model of the object, identifies a pose of the object in the surgical space, aligns the model with the pose of the object to define depth data for the model in the surgical space, and generates a depth map in the surgical space for at least a portion of the object based on the depth data for the model. Corresponding systems and methods are also described.
