Abstract
A system includes one or more processors configured to execute instructions to cause the system to access a plurality of images generated by one or more imaging devices of an endoscope when the endoscope is disposed within anatomy of a patient, for each of the plurality of images, determine a value for each of one or more image reliability metrics, and determine a position of the endoscope within the anatomy of the patient based at least in part on the one or more image reliability metrics of each of the plurality of images.
Claims20
A system comprising:
- one or more processors configured to execute instructions to cause the system to:
- access a plurality of images generated by one or more imaging devices of an endoscope when the endoscope is disposed within anatomy of a patient;
- for each of the plurality of images, determine a value for each of one or more image reliability metrics;
- and
- determine a position of the endoscope within the anatomy of the patient based at least in part on the one or more image reliability metrics of each of the plurality of images.

A system comprising:
- one or more processors configured to execute instructions to cause the system to:
- access preoperative model data relating to a luminal network of a patient;
- generate a virtual model of the luminal network based at least in part on the preoperative model data;
- identify one or more features in the virtual model;
- access a plurality of images captured by an endo scope camera when the endoscope is disposed in the luminal network;
- identify one or more of the plurality of images as reliable images based on one or more image reliability metrics;
- identify one or more features in the one or more reliable images, the one or more features relating to the identified one or more virtual features in the virtual model;
- and
- determine a position of the endoscope based on a comparison of the one or more features with the one or more virtual features.
