1. Logic for calibrating a vision system of an object, configured to:

  • capture, via a first image sensor of the vision system, a first image of a plurality of objects;

    capture, via a second image sensor of the vision system, a second image of the plurality of objects, where the plurality of objects is located in an overlapping region of a field of view of the first image sensor and a field of view of the second image sensor;

    determine a position and orientation of the first and the second image sensor relative to the plurality of objects based on the first and the second captured image, respectively;

    determine a relative position and orientation between the first and the second image sensor based on a result of the determining a position and orientation of the first and the second image sensor;

    determine extrinsic parameters of the first and the second image sensor in a reference frame based on results of the determining a relative position and orientation between the first and the second image sensor; and

    determine intrinsic parameters of first and the second image sensor based on the first and the second captured image, respectively.
