With odometry

Without odometry

Since the dataset has pretty narrow sensor view angle in z-direction placed close to the floor (25 cm!), localization is not easy even if odometry is used.

The accuracy of the result depends on the sensor configuration and parameters should be tuned for different sensor configuration.
