A monitoring unit is provided in order to determine the position and/or location and/or movement of the tool on the basis of a specified starting situation using the detected sensor data. The device is characterized in that in order to calibrate the sensor (s), at least one image capturing unit is provided which is designed to capture one or more images of the tool at least at specified points in time or in intervals; an image analysis unit is provided for determining the position and/or location and/or movement of the tool; and the monitoring unit is designed to calibrate the sensor data in order to process the data. ## Claims ### Claim 1 A device having a tool for monitoring the position and/or attitude and/or movement of the tool, the tool having an inertial sensor such as a gyroscope sensor and/or an inertia sensor mounted on it, further comprising a supervisory unit, at least one image capture unit and an image evaluation unit, wherein the supervisory unit is designed to determine a position and/or an attitude and/or a movement of the tool, starting from a specified initial situation, on the basis of the captured sensor data from the inertial sensor, wherein the image capture unit is provided for calibrating the inertial sensor, the image capture unit being designed to capture one or more photographs of the tool at least at specific times or in specific time intervals, wherein the image evaluation unit is provided for determining the position and/or attitude and/or movement of the tool, and wherein the supervisory unit is designed to calibrate the sensor data from the inertial sensor in order to process the data from the image capture unit, wherein the device further comprises a locating device, the locating device being designed to have an ultrasonic transmitter and an ultrasonic receiver, the locating device being designed to locate the tool by determining the distance between the ultrasonic transmitter and the ultrasonic receiver by way of time-of-flight measurements on ultrasonic signals, the ultrasonic signals being able to be used to determine the distance between applicable transmitters and receivers, wherein the work area of the locating device operating by means of time-of-flight measurement stretches beyond an image area of the image capture unit and there is provision for the presence of the tool in the image area of the image capture unit to be detected by the locating device in order to locate the tool by way of time-of-flight measurements on the ultrasonic signals. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein the supervisory unit is designed so that the data from the inertial sensor are matched against those from the image processing, and/or the inertial sensor is calibrated, when the tool is in the image area of the image capture unit. ### Claim 3 (depends on 1) The device as claimed in claim 1, wherein the supervisory unit is designed so that the data from the inertial sensor are regularly matched against those from the image processing, and/or the inertial sensor is calibrated, when the tool is in the image area of the image capture unit. ### Claim 4 (depends on 1) The device as claimed in claim 1, wherein the locating device comprises electromagnetic sensors. ### Claim 5 (depends on 1) The device as claimed in claim 1, wherein the device further comprises a data transmission unit, the data transmission unit being designed not only for the data transmission of data from the inertial sensor but also for the data transmission of and/or of other data/information/parameters, in particular to transmit a trigger signal from the locating transmitter. ### Claim 6 (depends on 1) The device as claimed in claim 1, wherein the tool is a handheld tool such as a screwdriver, a drill or the like.
