1. A computed tomography (CT) machine system, comprising:
a three-dimensional (3D) camera;
a computing device; and
a drum-shaped component including (i) a cylindrical body including a window, the cylindrical body being identified with a central axis, and the center of the cylindrical body being provided with a hollow portion which is rotationally symmetric about the central axis, and (ii) a rotating component disposed in the cylindrical body, the rotating component being rotatable about the central axis,
wherein the rotating component comprises an arrangement of a plurality of trigger marks,
wherein the 3D camera is configured to capture, through the window, an image of the plurality of trigger marks that are arranged in the rotating component to generate image data that is transferred to the computing device,
wherein the window comprises a lens structure that enables the 3D camera to focus on the plurality of trigger marks, and
wherein the computing device is configured to determine state data of the CT machine based upon the transferred image data.
