Virtual 3D Heat Human Modelling

In modern times, with the revolutionary changes and remarkable innovations on practical and brilliant materials, a growing trend on practical and smart wearable products have been presented and accepted by the marketplace. Clothing is one of the most typical branches. For some fit or restricted fit functional clothing, more design elements on human anatomy, physiology, pathophysiologic and biomechanics have been performed by them to improve the special functions such as body cover, recovery, treatment, treatment, shaping and performance enhancement.

Mannequins, as one of the productive design tools, also called human being model, are frequently-used by fashion designers, patternmakers and manufacturers, which equip them with tangible or exclusive 3D model. Besides, digital 3D real human models are progressively adopted to enhance the efficiency and sustainability in these real human centred disciples. Geometry real human model (G-model) presents the basic dimensional information of body. In front of these new revolutions on design and technology trends, the original G-model may not reply well to the growing new requirements on design and making progress of efficient clothing. The digital body applied to fashion and functional design and creation need be endued with more effective information of the body. There is a necessity toward launching functional individuals model, as an accelerating, boosting and inspiring tool for popular and functional product design, specifically for efficient clothing design.

Body heat is a essential feature of human beings, which implies the comfort and health status of the body. As a high temperature transfer system, human body requires well-balanced thermoregulatory control loop. Clothing is often thought to be the second pores and skin of our body which can fulfil the functions of managing heat and dampness conditions and thus provide thermal comfort.

Besides, problems like sub-health and ageing people gradually get more attentions on medical care. Because of the significant importance of body temperature in indicating the pathophysiologic top features of the human body as emphasized by medical researchers in clinic, functional clothing with thermal functions like treatment and treatment will be a meaningful, practical and innovative efficient product to manage the body, like a special wearable medicine.

Science and technology are changing the life span of the humans. Unquestionably, efficient and smart products will be the ongoing trend for future years. The thinking about the insiders, like analysts, designers or product coders, must be progressive with the tidal current of developments in technology and technology.

To develop thermal related functional products, a visualised and quantified individuals model is essential and prerequisite. Without exact and reliable thermal information exposing the inside secrets of the human body, the procedure of useful product development is like that a blind man seems an elephant. Aworkmanmustsharpenhistoolsifheis to dohisworkwell. There's a knowledge difference and a tool absence for exact and visualised useful design and developing. To release the thermal real human modelling (T-model) is a far-sighted and necessary step.

With the swift improvements of medical imaging and anthropometric technology, 3D body scanning and 2D Infrared thermography (IRT) provide relatively appropriate and noticeable information of the human body, which help to further understand human body from physical, physiological and pathophysiologic aspects. 3D body scanners, as devices to capture the whole body and create a set of dimensionally correct data, are trusted in many areas, such as human modelling and human-centred product development in fashion industry. IRT has been used as a highly effective and non-invasive medical medical diagnosis tool, which really helps to monitor your skin temperature circulation and evaluate the health conditions of the human body within an ocular way. Both of these facilities lay a solid foundation for the practicability of thermal individuals modelling.

1. 2 Goals and objectives

According to the knowledge distance and the tool absence for accurate and visualised efficient design and processing, besides the practicability predicated on the increasingly advanced medical imaging and anthropometric technology, five major aims and targets of the study had been set up as shown from a to e.

  • An in-depth discovery of the actual relationship among bodily anthropometric variables and physiological properties like body temperature ranges.
  • A systematic methodology on creating visualised, quantified and individualized 3D thermal human modelling (Ti-model) with physiological features.
  • A systematic approach on creating visualised, quantified and individualized 3D thermal human modelling (Ti-model) with pathophysiologic features.
  • Averaged 2D thermal images to be similar with individual's IR images to discover the unseen abnormity of people for medical and diseases monitoring.
  • 3D thermal real human modelling (Ta-model) to be equivalent with Ti-model to discover the invisible abnormity of individuals for healthcare and diseases monitoring.

1. 3 The significances of the research

This study will provide brand new and far-sighted alternatives for the exact accomplishment of functional products development, in special for practical clothing, with quantified and visualised T-models. The multi-disciplinary research broadens the field of vision for the individual and presenting the relationships of physical, physiological and pathophysiologic features from aspects of statistics, 2D and 3D. The significances of the research should be manufactured in two aspects.

For theoretical base, this research will built up a linkage between physical and physiological top features of the individual which can awake the thinking on further quantitative between them and providing highly recommended index in practical design software. Besides, this review will advance the data on the commonality of the skin temp distributions of the human beings, which have great interpretation for physiological research, medical clinic diagnose and ergonomic design applications.

For individual applications, this new model can be applied to functional product development. Especially for functional clothing creators, they'll be in a position to do 3D useful design, 3D routine making and exclusive fitting in an accurate, useful and traceable way. In the changing times of 3D printing technology, it is an indispensable tool and platform for the antecedent get-togethers in medical care areas.

1. 4 Research methodology

A multidisciplinary methodology crossover thermal physiology, medical diagnose, computer images, ergonomics and practical design is followed to accomplish the aims and goal of the analysis. The medical imaging and anthropometry technology help acquire physical and physiological data of the body from individual tests. From the viewpoint of information, 2D and 3D dimensions, generalization and individual approaches on human thermal properties should be analysed through statistical software, numerical encoding software and 3D design software.

1. 5 Thesis organization

This research has been conducted in the backdrop stated above. The overall organization of the thesis is shown in Physique 1-1.

Chapter 1 is the overall introduction of the complete thesis including the background the study, aim and goals of the study, significances of the study and research technique.

Chapter 2 is the theoretical basis of the complete thesis including the books review on two emphasized and completed research areas, human thermal function and clothing, and 3D individual model put on Computer Aided Design popular industry.

Chapter 3 presented the research technique of this review. The innovations of medical imaging and anthropometry technology, an in-depth and specific base had been taken to further understanding human body in physical and physiological aspects. The computer graphic technology provided dependable software and tools to attain the desired research aims and complete the interdisciplinary research.

The occupation of the info acquired from the individual experiments were unveiled in Section 4, 5 and 6 which constitute a organized understanding system of the human body from the point of view of statistics, 2D and 3D dimensions, universality and individuality on thermal properties.

In Section 4, statistic evaluation through correlation examination and Principal Aspect Analysis (PCA) were conducted to discover the relationship among anthropometric variables and body temperature ranges, which built up quantified links of physical and physiological top features of the humans.

Individualized thermal individual modelling methods and results were unveiled in Chapter 5. Within this chapter, organized introductions and illustrations were presented detail by detail on how to construct a Ti-model with physiological and pathophysiologic features. The first step was to pre-process the 3D body scanning data including data alignment, data cleaning and part selections. Simultaneously, skin area temperature data models were pre-processed by plotting into 2D thermal images with physiological or pathophysiologic features by mathematical programming. The very last step was thermal model construction. The 2D thermal images with physiological or pathophysiologic features were projected to 3D human body and the related Ti-model with physiological or pathophysiologic features was created. This chapter was to quantify and visualise the unseen body code conveyed by the skin temperature in the aspect of three-dimension and individualization.

Chapter 6 presented the studies on distribution regularity of pores and skin temperature from two proportions with averaged IR images and its own program on three-dimensional thermal individuals modelling (Ta-model). Within the encoding environment of Matlab software, numerical computation and anatomical landmarks of our body were combined to discover the regularity of epidermis heat distributions of the human beings. The mapping process from 2D IR images to 3D individual G-model created Ta-model. The types of evaluating with individual's IR images and Ti-model have been offered, which helped to identify the invisible individual differences for professional medical and diseases monitoring. This research improvement bridges on the gap between research research and technology applications on thermal studies with quantified and visualised methods.
