Anthropometric parameter based human modeling has been attractively explored and applied in human body related product design industries. However, how to conveniently obtain precise anthropometric parameters and how to make the human modeling results fit the anthropometric parameters well are still unsolved problems. In this paper, a smart garment attached with a mechatronic sensor-net has been designed to measure multiple body dimensions precisely and simultaneously. Geometrically, this sensor-net corresponds to a feature curve-net. A 3D human model is statistically reconstructed with body measurements initially and is further optimized with the shape constraints from the feature curve-net. Experimental results verify the effectiveness of our approach in both human body measurement and 3D human body modeling.

According to the design requirements of garment CAD system, this paper summarizes and analyzes the flow, characteristics and existing problems of existing human modeling algorithms, and proposes a 3D human modeling method based on section ring calculation, and realizes the dynamic modeling of human body driven by joint points. Firstly, the human body shape is classified to create a 3D human body shape template library. On the basis of extracting feature points and feature lines of the human model, the relationship between the size change and the feature points is calculated by using simple linear scaling ratio. Through the mathematical modeling of chest curve, waist hip curve and longitudinal datum line, the fitting curve results which reflect the curve characteristics and are convenient for subsequent clothing deformation are obtained. The algorithm is simple and efficient. It can not only accurately reproduce the surface static characteristics of the original scanned human body, but also change the dynamic characteristics of the human body interactively, which can meet the basic requirements of the human body model in the process of fashion design.

In this article, we presented a new automatic three-dimensional-scanned garment fitting method for A-Pose-scanned human models. Both the garment and the human body were decomposed based on feature lines defined by various landmarks. The patches of the three-dimensional garment were automatically positioned around the human model by setting up the correspondence via feature matching. Virtual sewing was engaged to obtain the final results of virtual dressing. The penetration between cloth model and human model was solved by a geometrical method constrained by Laplacian-based deformation. The experimental results indicated that the proposed method was an efficient way for redressing various garments onto various human models while maintaining the original geometrical features of garments.

PurposeThe purpose of this paper is to develop an automated human body measurement extraction system using simple inexpensive equipment with minimum requirement of human assistance. This research further leads to the comparison of extracted measurements to established methods to analyze the error. The extracted measurements can be used to assist the production of custom-fit apparel. This is an effort to reduce the cost of expensive 3-D body scanners and to make the system available to the user at home.Design/methodology/approachA single camera body measurement system is proposed, implemented, and pilot tested. This system involves a personal computer and a webcam operating within a space of controlled lighting. The system will take two images of the user, extract body silhouettes, and perform measurement extraction. The camera is automatically calibrated using the software each time of scanning considering the scanning space. The user will select a front view and a side view among the images captured, and specify the height. In this pilot study, 31 subjects were recruited and the accuracy of 8 human body measurements were compared with the manual measurements and measurements extracted from a commercial 3-D body scanner.FindingsThe system achieved reasonable measurement performance within 10 percent accuracy for seven out of the eight measurements, while four out of eight parameters obtained a performance similar to the commercial scanner. It is proved that human body measurement extraction can be done using inexpensive equipment to obtain reasonable results.Originality/valueThis study is aimed at developing a proof-of-concept for inexpensive body scanning system, with an effort to benchmark measurement accuracy, available to an average user providing the ability to acquire self-body measurements to be used to purchase custom-fit apparel. This system can potentially boost the customization of apparel and revolutionize online shopping of custom-fit apparel.

In this paper, the measurement result of the mean, standard deviation, the maximum value, the minimum value, and the 5th, 50th, 95th percentile data of the 95 item were given by measuring 234 divers. Height, weight and chest circumference were compared and analyzed with Chinese male adult human body dimensions. The ergonomics of body measurements in the application of diving industry were discussed. The paper emphasis when designing or building diving apparatus and rescuing equipment, we should not be completely according to the human body data of normal adults. Need to establish human body model of divers, and search the rule of divers.

Purpose. The primary objective of the study was to determine a way to obtain subject-specific body dimensions. The aim was then to develop linear statistical models for estimating human body geometry from a small number of body measurements. Methods. Internal (bone dimensions) and external (body) measurements were collected on 64 healthy adults representative of three morphotypes. Simple and multiple linear regression models between external and internal body dimensions were then obtained and assessed. Results. The statistical analysis provided 184 anthropometrical models which allow estimation of subject-specific external and internal data from 10 external dimensions that can be easily measured on any subject. Among them, 62 models had a 2SEE (i.e. twice the Standard Error of Estimate) lower than 10%. Conclusion. This study proposes a non-invasive approach to estimate both external and internal body dimensions.

Purpose The automatic body measurement is the key of tailoring, mass customization and fit/ease evaluation. The major challenges include finding the landmarks and extracting the sizes accurately. The purpose of this paper is to propose a new method of body measurement based on the loop structure. Design/methodology/approach The scanned human model is sliced equally to layers consist of various shapes of loops. The semantic feature analysis has been regarded as a problem of finding the points of interest (POI) and the loop of interest (LOI) according to the types of loop connections. Methods for determining the basic landmarks have been detailed. Findings The experimental results validate that the proposed methods can be used to locate the landmarks and to extract sizes on markless human scans robustly and efficiently. Originality/value With the method, the body measurement can be quickly performed with average errors around 0.5 cm. The results of segmentation, landmarking and body measurements also validate the robustness and efficiency of the proposed methods.

Anthropometry, the systematic measurement of human body dimensions and composition using standardized procedures, has long been one of the physical anthropologist's most important methods. Early work in biomedical anthropology used anthropometric variables to test associations among body types, body characteristics, and diseases. Today there is a renewed interest in anthropometry, ratios and equations derived from anthropometric measurements, and longitudinal changes in body measurements, for evaluating health and understanding disease in individuals and populations. The measurement of the human body is once again at the forefront of applied biomedical anthropology.
