Systems and methods for characterization of an endoscope and automatic calibration of an endoscopic camera system

A processor configured to execute instructions stored in memory to detect an anomaly in an endoscopic camera, the endoscopic camera including an endoscope and the camera including a camera head, wherein, when executed, the instructions cause the processor to:

• receive a lens descriptor associated with the endoscope, wherein the lens descriptor includes first calibration parameters indicating first characteristics of the endoscope independent of the endoscopic camera;
• acquire at least two image frames using the endoscopic camera, wherein each of the at least two image frames is captured with the endoscope in a different position with respect to the camera head relative to others of the at least two image frames;
• detect second characteristics for each of the at least two image frames;
• estimate a first rotation center using the second characteristics for the at least two image frames;
• estimate a second rotation center according to the first calibration parameters contained in the lens descriptor;
• compare the first estimated rotation center to the second estimated rotation center;
• and
• determine whether an anomaly exists according to the comparison.
