CALIBRATION ROUTINE FOR IMU MOUNTING ALIGNMENTS
The invention relates to a computer program product comprising a program code, wherein the program code is configured for calibrating mounting alignments of a set of inertial measurement units (IMUs) on a construction vehicle 1, wherein the set of IMUs comprises at least two IMUs each being mounted on different parts 3,6,7 of the construction vehicle 1, and provides an at least partially automatically executing calibration routine for the mounting alignments of the set of IMUs on the construction vehicle 1, wherein for the calibration routine the following is defined: a sequence of N calibration measurements, with N greater than or equal to three, is to be carried out by the set of IMUs, and for each I-th of the N calibration measurements, with I consecutively from one to N, an I-th pose of the construction vehicle 1 is to be adopted, wherein the following is carried out in course of the calibration routine: after adoption of the I-th pose of the construction vehicle the I-th of the N calibration measurements is initiated by an onset of a trigger event specifically predefined for the I-th of the N calibration measurements, wherein the N calibration measurements comprise at least acceleration values of acceleration sensors of the set of IMUs, and calibration data relating to the respective mounting alignments of the set of IMUs on the construction vehicle 1 are determined or updated based on the N calibration measurements.
