The present book is a result of the research activity aimed at developing a new measuring system for large scale dimensional metrology - the MScMS (Mobile Spatial coordinate Measuring System). In this field, the rising exigency of measuring quickly and with acceptable accuracy levels has promoted significant advances across the development of light and scalable technologies, which are easy to implement and flexible in their use. MScMS consists of multiple components with small dimensions connected by a wireless network and arranged around the measuring area, so as to allow rapid dimensional measurements to be performed in relation to large-size objects. This system, which was developed at Politecnico di Torino (Italy), is portable, reconfigurable and cheap.
