The comparison of azimuth and distance RMSE at different standard deviations of distance, with CV model. There are two sub-figures a and b in this figure, in which, under the CV model, the changes of fusion RMSE of azimuth and distance are described along with different standard deviations of distance. The fusion RMSE in a and b is the mean of all results covering all fusion time steps
