“…In recent years, the laser scanning systems have been widely applied in many industrial applications, such as medical imaging [1], quality assurance [2], machine vision [3,4] and reverse engineering [5,6]. The fast acquisition speed, the high accuracy, the good stability and the low cost make it one of the most promising techniques to obtain the geometric surface information.…”

The traditional three-dimensional measurement system based on linear-structured light usually involves mechanical scanning platforms to perform the linear scanning, which make the structure of the system huge and complicated. The emergence of the galvanometric laser scanner solves the problem by using a galvanometer to replace the mechanical scanning platform. The employment of the galvanometer can improve the speed of scanning and simplify the structure of the system. However, there are few approaches available to calibrate this kind of system. In this paper, a high-precision calibration method is proposed to calibrate the galvanometric laser scanning three-dimensional measurement system. A precision motorized linear stage and a planar target are applied in this method. The planar target is used for the camera calibration based on Zhang's method and the precision motorized linear stage for the laser plane calibration. The validity and accuracy of this method are evaluated by scanning the standard component. The experiments conducted suggest that the proposed method is valid and accurate for the calibration of the galvanometric laser scanning system.

“…It has also been utilized for medical engineering purposes, where body structures were scanned for assessment and, in some cases, replication purposes [32]. Objects have been scanned for reverse engineering purposes [33,34], quality assurance [35], creating object repositories (e.g., [36]), preserving historical artifacts [37] and assessing turbine blades [38] and concrete slabs [6].…”

Characterization of a Large, Low-Cost 3D Scanner

Imagery-based 3D scanning can be performed by scanners with multiple form factors, ranging from small and inexpensive scanners requiring manual movement around a stationary object to large freestanding (nearly) instantaneous units. Small mobile units are problematic for use in scanning living creatures, which may be unwilling or unable to (or for the very young and animals, unaware of the need to) hold a fixed position for an extended period of time. Alternately, very high cost scanners that can capture a complete scan within a few seconds are available, but they are cost prohibitive for some applications. This paper seeks to assess the performance of a large, low-cost 3D scanner, presented in prior work, which is able to concurrently capture imagery from all around an object. It provides the capabilities of the large, freestanding units at a price point akin to the smaller, mobile ones. This allows access to 3D scanning technology (particularly for applications requiring instantaneous imaging) at a lower cost. Problematically, prior analysis of the scanner's performance was extremely limited. This paper characterizes the efficacy of the scanner for scanning both inanimate objects and humans. Given the importance of lighting to visible light scanning systems, the scanner's performance under multiple lighting configurations is evaluated, characterizing its sensitivity to lighting design.

“…A large variety of object imaging applications have also been demonstrated. These include reverse engineering [18,19], validating product quality (e.g., for automotive products) [20] and digitally preserving historical artifacts [21]. Scanning has also been used to assess the bearing capacity of slab concrete, without destroying or damaging it, like is required by some methods [22], and assessing turbine blades [23].…”

Three-dimensional scanning serves a large variety of uses. It can be utilized to generate objects for, after possible modification, 3D printing. It can facilitate reverse engineering, replication of artifacts to allow interaction without risking cultural heirlooms and the creation of replacement bespoke parts. The technology can also be used to capture imagery for creating holograms, it can support applications requiring human body imaging (e.g., medical, sports performance, garment creation, security) and it can be used to import real-world objects into computer games and other simulations. This paper presents the design of a 3D scanner that was designed and constructed at the University of North Dakota to create 3D models for printing and numerous other uses. It discusses multiple prospective uses for the unit and technology. It also provides an overview of future directions of the project, such as 3D video capture.
