In the document of “sensor_accel” and “vehicle_acceleration”, the definition of the accel_x, accel_y and accel_z are difference.
For acceleration x, “sensor_accel” stated that it is the acceleration in “FRD board frame X-axis in m/s^2”. “vehicle_acceleration” stated that it is the bias corrected acceleration in “FRD body frame XYZ-axis in m/s^2”.
Is there any difference between FRD body frame and FRD board frame?
