1. A computer-implemented method of reducing distortions in image data, the method comprising:
assembling a camera, wherein the camera includes an on-board image sensor and a lens affixed based on a physical offset value;
determining a pair of offset values, wherein the pair of offset values includes a first offset value and a second offset value, the first offset value corresponds to a first offset of an optical center from an optical axis to an image sensor pointing reference of the assembled camera as the assembled camera is received in a kinematic mount at a first angle, and the second offset value corresponds to a second offset of the optical center from the optical axis to the image sensor pointing reference associated with the assembled camera as the assembled camera is received in the kinematic mount at a second angle, and the first angle and the second angle are distinct:
generating, based on the determined pair of offset values, a total offset value; and
causing a device to reduce, based on the total offset value, distortions in captured image data.
