1. A method comprising:
causing to be sensed, using a sensor of a camera, a first two-dimensional representation of an object displayed on a display screen, wherein the first two-dimensional representation is generated by transforming the object in a virtual three-dimensional space to orient the object in a particular pose with respect to the camera and simulating the object having the particular pose within a predetermined portion of a field of view of the camera;
generating, using the sensor of the camera, image data representing an image depicting a second two-dimensional representation of the object corresponding to the first two-dimensional representation of the object;
determining a relationship between the first two-dimensional representation of the object displayed on the display screen and the second two-dimensional representation of the object as depicted by the image; and
determining one or more calibration parameters based at least on the relationship.
