“…However, it is a challenge today to select a suitable 3D scanning system for a concrete application due to the current technological variety of available 3D scanning systems. These scanning systems are used in different fields of applications such as architecture (Maxwell, 2017), cultural heritage (Ouimet et al, 2015), biology (Friedman et al, 2015), forensic science (Larsson & Letalick, 2013;Wieczorek & Gorawska, 2017), orthopaedics (Salleh et al, 2017;Dessery & Pallari, 2018), construction (Senthilvel et al, 2017) and many others. In the recent years the market for hand-held 3D scanners extended increasingly in different price segments (EUR 500 to EUR 50,000).…”

ABSTRACT:Hand-held 3D scanning systems are increasingly available on the market from several system manufacturers. These systems are deployed for 3D recording of objects with different size in diverse applications, such as industrial reverse engineering, and documentation of museum exhibits etc. Typical measurement distances range from 0.5 m to 4.5 m. Although they are often easy-to-use, the geometric performance of these systems, especially the precision and accuracy, are not well known to many users. First geometrical investigations of a variety of diverse hand-held 3D scanning systems were already carried out by the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg (HCU Hamburg) in cooperation with two other universities in 2016. To obtain more information about the accuracy behaviour of the latest generation of hand-held 3D scanning systems, HCU Hamburg conducted further comparative geometrical investigations using structured light systems with speckle pattern (Artec Spider, Mantis Vision PocketScan 3D, Mantis Vision F5-SR, Mantis Vision F5-B, and Mantis Vision F6), and photogrammetric systems (Creaform HandySCAN 700 and Shining FreeScan X7). In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data was acquired by measurements with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.

“…Therefore, it is necessary to study the design of non-contact compression garments and pressure test methods for burn patients. At present, contactless methods include the theoretical calculation method [10][11][12][13][14] and the compression garment design methods based on mannequins. [15][16][17][18][19][20][21] In view of the difficulty and complexity of the theoretical calculation method, many scholars have turned their attentions to mannequins for the design of compression garments and the evaluation of garment pressure.…”

Compression garments apply garment pressure to suppress growth and flatten hypertrophic scars caused by serious burns. In order to reduce the pain caused by a trial-made compression garment for burn patients, one of the most studied parts of the human body, the arm, was selected as the research object, and the characteristics of an arm model that could be used for compression sleeve design and garment pressure measurement were studied. Five human arm models were made based on three-dimensional-printing technology, and then a compression sleeve was made based on Laplace’s law. After that, the garment pressures that the compression sleeve applied on the five human arm models and on a real human arm were tested. Finally, the garment pressure magnitudes and the distribution on a real human arm and on each arm model were compared and analyzed. The results show that when other conditions were consistent, the garment pressure on the arm model was inversely proportional to the hardness of the model, and the garment pressure magnitudes and the distribution on the model whose hardness was close to that of a real human arm were very similar to those of a real human arm. Moreover, consistent with the previous research results, the garment pressure of the compression sleeve that was made based on Laplace’s law increased with the increase of the arm circumference, and it decreased with decreasing circumference. The results of this study can provide a reference for the exploration of a mannequin that can substitute for a real human body in the design of compression garments.

Purpose The area shrinkage of the body under pressure is very important to evaluate the comfort of pressure sense, and it is an important index that appraises compression garment. The purpose of this paper is to obtain the area shrinkage mass of the waist cross section by using the finite-element method (FEM), and the waist of women’s pantyhose could be designed with a different degree of elasticity during the course of design based on clothing pressure comfort. Design/methodology/approach This study aimed at the problems existing in the wearing of women’s elastic pantyhose, took the waist of pantyhose as the research object, and the contact between human body and pantyhose as elastic contact. The finite-element model of the waist cross section and elastic pantyhose fabric was acquired through CT scan and Mimics software. After simulating on the corresponding displacement distribution of the waist of sample elastic pantyhose during the process of dressing by using ANSYS, the authors divided the waist cross section into 24 equal regions according to angle (every 15 degrees as a region), and then the area shrinkage mass of each region was obtained by area calculation formula. According to the tendency of area shrinkage distribution, the waist of women’s elastic pantyhose could be designed for different regions of tension considering the pressure comfort, so as to guarantee that the wearing comfort can be maintained on the premise of ensuring the functionality of the elastic pantyhose. Findings In this paper, the authors obtained the area shrinkage mass of elastic pantyhose at waist cross section, and this area shrinkage distribution could be used as an objective evaluation index for pressure comfort. All these solutions are of great significance to the optimization design of pantyhose and can provide theoretical basis for the structural improvement of functional pantyhose and the prediction of clothing pressure. Originality/value This paper simulated the area shrinkage mass for the waist of elastic pantyhose by using FEM, and the waist of women’s elastic pantyhose could be designed for different regions of tension considering the pressure comfort according to the area shrinkage distribution tendency, so as to guarantee the wearing comfort during the wearing process.
