Zusammenfassung:	An apparatus for identifying a tool joint connection is disclosed. The apparatus comprises a scanning system configured to scan an exterior of a drill string and at least one distance measuring sensor mounted to a movable platform, and a computer operatively connected to the scanning system and the distance measuring sensor. The computer is configured to receive data from a scanning of the exterior of the drill string and compare the data to a reference which enables a presence of the tool joint connection to be determined. A method for identifying a tool joint connection is also disclosed. FIG. 6 for publication - LINE X H = LINE X (tan(a) - tan(#))
