“…Handheld 3D scanners are often based on stereoscopic vision and triangulation: the device consists of at least one but often two cameras triangulating what they are seeing and processing it to create a 3D reconstitution [ 5 ]. With the laser technology, one or several laser lines are projected on the target, and their deformation is monitored by the cameras so that the scanner can establish the spatial location of the deformed lines [ 6 ]. Once the acquisition is complete, a point cloud or a mesh representing the scanned object’s surface is generated.…”

This paper proposes the use of a pseudo-3D ball-lattice artifact to characterize a handheld laser scanner from a metrological standpoint. The artifact allows the computation of local and global errors in measurement by using the reference-frame-independent parameters of size, form, and distance within the measuring volume of the scanner, and in a single point cloud, without the need for registration. A set of tests was performed using the whole measuring volume, and three acquisition parameters, namely the orientation of the sweeps during the scans, the exposure time, and the distance to the scanner were analyzed for their effects on the accuracy of the scan data. A composite error including the errors in measuring size, form, and distance was used as a single figure of merit to characterize the performance of the scanner in relation to the data-acquisition parameters. The orientation of sweeps did not have a considerable effect on the errors. The accuracy of the scan data was strongly affected by exposure time and its interaction with the distance at which the artifact was scanned. The errors followed a quadratic trend with respect to the distance of the artifact to the scanner. The tested scanner performed best at its manufacturer’s recommended stand-off distance.

“…It is well known that a range discontinuity on a surface affects the accuracy of 3D imaging systems [2]. Furthermore, continuity between surfaces may have an impact on the profile measuring capability of a 3D imaging system [8,[43][44]. It is in this context that other types of artefacts have been tested.…”

“…It is interesting to note that the three main optical distance-measurement techniques used in commercial systems (see Figure 3) occupy distinct measurement ranges or volumes with some overlap in both scan range or volume and types of applications [1][2][3][4]8]. Here we identify them with generic terms linked to the measurement range distance: x nano/micro range (< 10 mm), x close range (10 mm to 2 m), and, x mid-to-long range (> 2 m).…”

“…All of the metallic and coated-glass artifacts selected for the characterization target are grouped on the same plate in a target case for portability. To define a set of test procedures that is practical, simple to perform and easy to understand, they decided to use a terminology that is already well-known in the manufacturing field, i.e., geometric dimensioning and tolerancing (GD&T) [8,47].…”

Abstract. A significant issue for companies or organizations integrating non-contact three-dimensional (3D) imaging systems into their production pipeline is deciding in which technology to invest. Quality non-contact 3D imaging systems typically involve a significant investment when considering the cost of equipment, training, software, and maintenance contracts over the functional lifetime of a given system or systems notwithstanding the requirements of the global nature of manufacturing activities. Numerous methods have been published to "help" users navigate the many products and specifications claims about "quality". Moreover, the "best" system for one application may not be ideally suited for another application. The lack of publically-available characterization methods from trusted sources for certain areas of 3D imaging make it difficult for a typical user to select a system based on information written on a specification sheet alone. An internationally-recognized standard is a vehicle that allows better communication between users and manufacturers. It is in this context that we present a progress report on standards developments to date in the diverse, but finite, world of non-contact 3D imaging systems from the nanometre to the 100 m range.
