The Belle II is the next generation of famous B-physics experiments and they would like to continue in success of predecessors. To provide better measurements and extend limits, the upgrades were necessary.
One of the main upgrades was expanding a strip silicon detector using a pixel detector. Higher precision requires more sophisticated alignment procedure, parametrization, validation and monitoring techniques.
Since the first commissioning of vertex detector, a lot of experiences have been acquired and many of features have been observed.
