1. A method for calibrating a camera, the method comprising:
accessing, by an auto-calibration module of a second camera, calibration parameters of a first camera of a plurality of cameras, the first camera disposed a first location;
moving a reference object along a path;
detecting, by a detector of the auto-calibration module, that the reference object is within an overlapping field of view of the first camera and the second camera of the plurality of cameras, the second camera disposed at a second location, the reference object being detected based on predefined characteristics of the reference object; and
in response to detecting that the reference object is within the overlapping field of view of the first camera and the second camera, calibrating the second camera based on the calibration parameters of the first camera.
