1. A method for analyzing an object positioned within a patient, comprising:
navigating an elongate body to a location within the patient and proximate to the object;
capturing sequential images of the object with an imaging sensor;
navigating the elongate body into different orientations, different positions, or both, during the capture of the sequential images;
determining orientations and positions of the elongate body during the capture of the sequential images based on a set of sensor data;
comparing the orientations and positions of the elongate body determined based on the set of sensor data for at least one captured sequential image to the orientation and position determined based on the set of sensor data for at least another captured sequential image; and
analyzing, with a processor, the sequential images of the object and the comparison of the orientations and positions to estimate a shape of the object.
