Claim 13:
14. A method of operating a wellhead alignment system, the method comprising:
receiving, at one or more processors, a first image captured by a camera fastened to a drilling rig, wherein the camera captures the first image a first field of view;
applying, using the one or more processors, computer vision algorithms to identify a position of a center of a visual marker coupled to a wellhead in the first image;
calculating, using the one or more processors, a first offset between the drilling rig and the wellhead based on the position of the center of the visual marker in the first image;
moving the drilling rig based on the first offset;
receiving, at the one or more processors, a second image captured by the camera at a second field of view that is narrower than the first field of view;
applying, using the one or more processors, computer vision algorithms to identify a position of a center of the visual marker in the second image; and
calculating, using the one or more processors, a second offset between the drilling rig and the wellhead based on the position of the center of the visual marker in the second image.
