Calibration of individual and arrayed cameras using images and video

A system for correcting camera lens distortion, the system comprising:

• at least one memory for storing computer-executable instructions;
• and
• at least one processor for executing the instructions stored on the memory, wherein execution of the instructions programs causes the at least one processor to perform operations comprising:
• receiving at least one image of a calibration object, wherein the image is captured via the camera lens and the lens has lens distortion, and wherein the calibration object has a plurality of straight lines;
• fitting a plurality of geodesics in the image, the plurality of geodesics in the image corresponding to the respective plurality of straight lines of the calibration object;
• determining at least one Christoffel connection equation for the plurality of geodesics;
• determining a metric based on the Christoffel connection equation, the metric comprising a first distorted radial coordinate;
• determining an undistorted radial coordinate based on the first distorted radial coordinate;
• inverting the undistorted radial coordinate;
• and
• generating an undistorted image based on the inverted undistorted radial coordinate.
