“…In particular, Ergonomics includes: 65,81 portability: it is intended as the capability of the system to be easily moved within the working environment; flexibility: it refers to system capabilities to apply to different working environments and to perform various measurement tasks; handiness: it means easiness of installation and use; scalability: it refers to the capability to cover differently sized and shaped volumes. Table 10 reports a classification of the most diffused optical LSDM systems on the basis of Ergonomics, as well as Costs (discussed in Section 4.5.1) and Total accuracy.…”

Last decades witness an increasing interest in Large-Scale/Large-Volume Dimensional Metrology (LSDM). Many fields of application, ranging from construction to shipbuilding and aerospace, have shown more and more accurate and versatile systems for geometric control and tolerancing. Especially in the last ten years, optical technology has registered a fundamental step forward both in terms of metrological performances, versatility and convenience of use. This is further demonstrated by the current large diffusion of laser tracker and photogrammetric systems. The growth is also complemented by the development of new standards, even though a comprehensive body specific for LSDM is still lacking. The twofold aim of the present survey is to present a bibliographical and bibliometric analysis of the field and to propose a scheme of classification of the main current approaches. As an output of this paper, a "LSDM Multi-perspective Model" is introduced, according to which dominant technologies and restrictions are analyzed with the aim of individuating current lacks and defining the roadmap for future development of new instruments and systems.

“…1) [8]: a network ("constellation") of wireless sensor devices, suitably distributed all around the measurement volume, to estimate 3D coordinates of reflective markers; a mobile wireless and hand-held probe, equipped with two reflective markers, to "touch" the measurement points; a dataprocessing system, using Bluetooth connection, to acquire and elaborate data sent by each network node. An earlier prototype of MScMS exploited UltraSound (US) transceivers in order to communicate and evaluate mutual distances between the network nodes and the hand-held probe [5]. The poor characteristics of US devices (non-punctiform dimensions, speed of sound dependence on operating temperature, reflection and diffraction of US signal, etc.)…”

“…The poor characteristics of US devices (non-punctiform dimensions, speed of sound dependence on operating temperature, reflection and diffraction of US signal, etc.) caused a low accuracy in the measurement results [5]. In order to enhance system performance, current version makes use of IR-based optical sensors (IR cameras), estimating the position of passive retro-reflective markers from their projections in different camera views.…”

Abstract. According to the increasing interest in metrological systems for the dimensional measurements of large-size objects in a wide range of industrial sectors, several solutions based on different technologies, working principles, architectures, and functionalities have recently been developed. Among all, the most flexible and easily transportable solutions are those that have aroused most interest and have found greater success. In order to address the needs of Large-Scale Metrology (LSM) applications, a distributed flexible system based on a network of low-cost InfraRed (IR) sensors -the Mobile Spatial coordinate Measuring System II (MScMS-II) -has been developed at the Industrial Quality and Metrology Laboratory of Politecnico di Torino. This paper presents a preliminary uncertainty assessment of the system referring to the measured point coordinates in the 3D space, focusing on the sources of measurement uncertainty and the related propagation laws. A preliminary metrological characterization of MScMS-II architecture, experimentally evaluated through a system prototype, is also presented and discussed.
