Abstract

resumo método e sistema para recalibragem de sensor, de preferência, por meio da determinação de um viés do sensor para uma unidade de medição inercial (imu) em um veículo. o viés do sensor é determinado por uma medição da imu em uma primeira orientação, e, em seguida, tendo uma segunda medição do imu em uma segunda orientação, a qual é rotacionada em aproximadamente 180° em relação à primeira orientação.Abstract Method and system for sensor recalibration, preferably by determining a sensor bias for an inertial unit of measurement (imu) in a vehicle. sensor bias is determined by a measurement of the imu in a first orientation, and then taking a second measurement of the imu in a second orientation which is rotated approximately 180 ° from the first orientation.
