| description | A method (100) for calibrating a plurality of sensors (21-24) each comprising a magnetometer (31), a gyroscope (32) and an accelerometer (33), the method comprising: providing (111) a first device (10) comprising at least one cavity (15-18) adapted for introduction of one or more sensors (21-24); introducing (112) each sensor of the plurality of sensors (21-24) into the first device (10); transmitting (113), from each sensor of the plurality of sensors (21-24) to a computing apparatus (40), a first measure corresponding to the respective magnetometer (31); determining (114), the computing apparatus (40), whether differences between the first measure of each sensor and the first measure of the other sensors of the plurality of sensors (21-24) are lower than a predetermined threshold; and calibrating (115) the plurality of sensors (21-24), if at least one of the differences between the first measures is equal to or greater than the predetermined threshold, by rotating the first device (10) or a second device (10) with the plurality of sensors (21-24) introduced therein, the second device comprising at least one cavity (15-18) adapted for introduction of one or more sensors (21-24). Also, a system (5) for calibrating a plurality of sensors (21-24). |
