Abstract

Método y sistema para recalibrar un sensor, preferentemente determinando una desviación del sensor de una unidad de medición inercial (IMU) en un vehículo. La desviación del sensor se determina tomando mediciones en tres diferentes actitudes, determinando una esfera de valores posibles de desviación de cada medición y determinando después una intersección de las tres esferas.Method and system for recalibrating a sensor, preferably determining a sensor offset of an inertial measurement unit (IMU) in a vehicle. The sensor deviation is determined by taking measurements in three different attitudes, determining a sphere of possible deviation values for each measurement and then determining an intersection of the three spheres.
