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 meio de medições em três atitudes diferentes, determinando uma esfera de possíveis valores de viés para cada medição, em seguida, determinar uma intersecção das três esferas.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 measurements at three different attitudes, determining a sphere of possible bias values for each measurement, then determining an intersection of the three spheres.
