Abstract: An offset for a first milking tool in a tool carrier of an automatic milking machine is determined as a spatial vector between a tool reference position (TRP) and an estimated actual position (TAP) of the milking tool. A three-dimensional image data is registered that represents a teat (T) during attachment to and/or detachment from the milking tool. The image data is processed by searching, within a search zone, for a predefined part (MP) of the teat (T) while the teat (T) is attached to the milking tool. Provided that the predefined part (MP) fulfills a measurement criterion, a distance (doff) is calculated between a specific point of the predefined part (MP) and the tool reference position (TRP). The offset is then determined based on the calculated distance (doff).
