Abstract:
1. An endoscope calibration system, the system comprising: a calibration target; an interface assembly having first and second portions, wherein the first portion is adapted to receive an endoscope, wherein the second portion is adapted to receive the calibration target, wherein the first and second portions are rotatably coupled to each other, wherein the endoscope is positioned to capture an image of the calibration target when the endoscope is received by the first portion and the calibration target is received by the second portion, and wherein the image of the calibration target rotates in an image plane of the endoscope as one of the first and second portions rotates relative to the other one; and a processor configured to cause one of the first and second portions to rotate relative to the other so that images of the calibration target captured by the endoscope when the endoscope is received by the first portion and the calibration target is received by the second portion are captured at different rotation angles, process the images of the calibration target to generate calibration data, and use the calibration data to calibrate the endoscope.
