Three calibration points attached to a monumental building in the Vijzelstraat in Amsterdam

Three calibration points attached to a monumental building in the Vijzelstraat in Amsterdam. Their 3D position can be measured exactly using a laser, and it is used to monitor building movement because of the building of the north-south metro tunnel. The high-tech system was installed after several monumental centuries-old homes were seriously damaged because of the construction of the tunnel below them.
