TABLE II:

Mean RMSE between the noise-free and noisy estimation of translation [mm] / rotation [°]. All values are the result of averaging over five independent noise simulations of one scan. The rows and columns show the exponents fa and fg of the noise factor for the accelerometer resp. gyroscope. RMSE values for both noisy acceleration and angular velocity that are below 1 for translation and rotation are highlighted as bold.
