A METHOD FOR CALIBRATING AT LEAST ONE SENSOR BY USE OF AT LEAST ONE CALIBRATION SENSOR

The invention relates to a method for calibrating at least one sensor (1) by use of at least one calibration sensor (2), wherein the at least one sensor (1) and the at least one calibration sensor (2) are moving relative each other during calibration, the method comprising:- obtaining information indicative of a proximity time period (pt) when the at least one sensor (1) and the at least one calibration sensor (2) are and/or will be in a predefined proximity zone (PZ) of each other for a time period which is sufficient for calibration;- obtaining information about a refractory time period (rs, rc) for at least one of the at least one sensor and the at least one calibration sensor, the refractory time period defining a time period between two consecutive sensor readings in which the sensor is unable to take a sensor reading;- calibrating the at least one sensor by a sensor reading of the at least one sensor and a sensor reading of the at least one calibration sensor, which sensor readings are taken when they are in the predefined proximity zone (PZ), wherein the refractory time period (rs, rc) for the at least one of the at least one sensor and the at least one calibration sensor is considered by delaying its sensor reading such that it is ensured that the sensor readings of the at least one sensor (1) and the at least one calibration sensor (2) are spatially and temporally aligned for the calibration.
