Beschreibung
Zusammenfassung:	A system can include a tong assembly, a tong positioning device configured to adjust a vertical height of the tong assembly, one or more calibration marker secured to the tong assembly, and a camera disposed at a camera position at which the calibration marker is within a field of view of the camera. A method of vertically positioning a tong assembly can include taking a digital image of a tong assembly and one or more calibration marker, identifying a pixel position of the calibration marker in the digital image, and adjusting a height of the tong assembly based in part on the pixel position of the calibration marker.
