A Low-Cost Contactless Overhead Micrometer Surface Scanner

Abstract

The design and implementation of a contactless scanner and its software are proposed. The scanner regards the photographic digitization of planar and approximately planar surfaces and is proposed as a cost-efficient alternative to off-the-shelf solutions. The result is 19.8 Kppi micrometer scans, in the service of several applications. Accurate surface mosaics are obtained based on a novel image acquisition and image registration approach that actively seeks registration cues by acquiring auxiliary images and fusing proprioceptive data in correspondence and registration tasks. The device and operating software are explained, provided as an open prototype, and evaluated qualitatively and quantitatively.

A Close-Range Photogrammetric Surface Scanner and its Evaluation

“…The motorised apparatus has been proposed in [3] for the acquisition of 2D surface mosaics, in micrometre scale. It is reused in this work, to obtain 2.5D surface digitisations.…”

“…This work employs the contactless, flatbed photogrammetric scanner from [3] which was developed for the creation of 2D image mosaics of surfaces in the micrometre range. This scanner is Disclaimer/Publisher's Note: The statements, opinions, and data contained in all publications are solely those of the individual author(s) and contributor(s) and not of MDPI and/or the editor(s).…”

“…2 of 18 comprised of off-the-shelf as well as printable components, which can be found in [3]. It costs less than 1000 USD, offers 19754 ppi resolution and has a scanning area of 33 × 37 cm 2 .…”

Multimodal Narratives for the Presentation of Silk Heritage in the Museum

“…The photographs collected comprise about 20 textile manufacturing documents with instructions, 110 overview photographs of looms and HdS workshops, 80 loom detail photographs, 10 photographs of silk threads, 50 photographs of plants used in the manufacturing of color pigments, and 5 sets of photographs of detailed ecclesiastical garments (about 800 photographs). For the acquisition of ultra-high-resolution scans of textiles, a contactless scanner was used, [68], that is a cost-efficient alternative to off-the-shelf solutions and provides micrometer scans with a resolution of 19.8 Kppi. Results can be seen in Figure 5.…”

A Mini-Review on the Applications of 3D Printing Technologies in Textile Design and Manufacturing

“…3D printing technology has evolved in many ways in the past decade and the main technologies employed have been made available in the form of open-source designs. These radically changed the landscape mainly through the evolution of the makers' movement and the adaptation of such designs to achieve various goals including for example the high-resolution capturing of planar surfaces and their reconstruction in the form of image mosaics [7] and 2.5 D digitisations [8].…”
