1. A method comprising:
identifying, by a camera calibration system, a first configuration of a set of differentiable point targets as depicted in a first image of a scene, the set of differentiable point targets each independently positionable within the scene and the first image captured by a first image capture device in accordance with a first pose of the first image capture device with respect to the scene;
identifying, by the camera calibration system, a second configuration of the set of differentiable point targets as depicted in a second image of the scene, the second image captured by a second image capture device in accordance with a second pose of the second image capture device with respect to the scene, the second pose different from the first pose; and
generating, by the camera calibration system, calibration parameters for a camera array that includes the first and second image capture devices, the calibration parameters generated based on the identified first and second configurations of the set of differentiable point targets and configured to represent the first and second poses of the first and second image capture devices.
