A transformation towards the digitalisation of maintenance is currently taking place, in which research is also being carried out in the area of inspection. Current literature shows efforts to track the path of an ultrasonic testing probe in various ways in order to link the recorded ultrasonic data with position information, i.e. coordinates. In most cases, the data is correlated to a part-independent reference system. In this way, however, no direct reference to the part coordinate system is established, which means that a future utilisation potential, e.g. in digital twins, is not fully exploited. In order to use the part itself as a reference, a hybrid tracking system is developed in this work, in which the part is tracked without markers, whereas an ultrasonic testing probe is equipped with passive reflection markers. This makes it possible to assign the sensor data of an ultrasonic inspection directly to the position of origin without having to equip the part with optical markers. Initial work is being done for the set up and the software development of the system. An experimental evaluation shows the general applicability. In addition, a method for visualising the recorded ultrasonic data using augmented reality is presented.
