The Application Of The Acquired Demiurgic Data By The Computed Tomography In Manufacture Design

The plastic art design of human body is the combination of human physiologyand aesthetics in art design. Its products will embody not only gorgeous characteristicof aesthetics but also the realistic mannequin in two or three-dimensional way. Thoseart works such as highly-realistic human-size dolls or high-tech humanlike robots arecases in point. And modern ergonomics, a integrated subject of human physiology and artdesign, is applied in the design of modern industrial products. For example, car seats, mobilephones etc. which offer extensive services for us and our society are based on the ergonomics.These products are devised in accordance with the artistic beauty as well as human bodyphysiology to guarantee the users’ comfort and safety. Therefore, the basis of human artdesign is to learn about the three-dimensional structure of human body and only in this way can high-tech humanlike dolls be made. On the other hand, it is necessary to know more aboutthe internal structure of human body to produce those highly realistic mannequins whichcould be used in car-crash experiments.The data collection of human body is the key element to human art design andthe ergonomic design. The body-dimension data (GB1000-88) was released in1988nationally, and this more-than-25year-old data were far from satisfactory, due to thelimitation of technology at that time. The data obtained through the artificialmeasurement and visual observation of joints fail to reflect the features of humanbone and body in a natural state accurately, like the natural curve of the humanvertebra and the body structure. Although modern video, camera and mechanicalmeasurement methods can provide certain reference data, like the body’s natural stateof human waist for car seat design etc. they cannot accurately reflect the features ofthe human skeleton and internal structure. Those highly realistic mannequins withthree-dimensional and internal structure which could be used in car-crash experimentsmay help obtain the internal damage of human body. Analyzing humanbody, bones, and internal structure in the living state and obtaining three-dimensionaldata, computed tomography (CT), the representation of the modern visible medicalequipment, makes it possible to observe and accurately measure the2D and3D dataof both surface and inside structure of human body. In this article, we measured and collected points,lines and3D data on the heads, limbs and trunk, and other skeletalfeatures of40cases of health human at18to40ages, meanwhile processed the digitaldata of the2D and3D images and calculated on the proportion of body aestheticsbased on the body height.This research takes the protruding parts of the body like the head, limbs and trunketc, as measuring datum point, using spiral computer tomography to collectthree-dimensional human body data in each point. And then the human bodycomputer tomography scan images and three-dimensional images of digital data willbe processed, for the purpose of forming height-based quantitative proportion in thelight of aesthetics. Data acquired from the living human body via computertomography showed that the male and female differences in ratios of thigh length toheight and head to height are1.6%and1.8%, respectively, and further revealed thatthe distinction in male and female hip width to height ratio reached2%. Thedifference of bone characterizations may be an important feature of gender differences,which is an important scientific ingredient to be considered in design of highlyrealistic mannequins. Data collected from computer tomography can not only bedigital but also be accurate to0.01mm. The utilization of computer, therefore, makeslarge sample of living human data collection and analysis possible. With the furtherhelp of image software, harnessing the optimal ratio of human body as well asrealistic three-dimensional image, people can produce a highly realistic mannequin.All these human data not only can be used for art design in advertisements, videogames, film and television animations and mannequins. With the development ofmodern science and technology, a large number of industrial product designs have tocount on data of human body acquired from computer tomography. Since all productsare designed to serve society and the human, artistic values as well as practical valuesof the products will be presented in the product design. In addition, humanity of theproduct should be emphasized, and only in this way can its design meet therequirement of market and the public. By means of computer tomography, thesehuman data can be generalized and classified. By reference to such data in thedesign, more human-oriented design concepts will be found in product design, whichcan endow the design of car seats, mobile phones, computer mouse, etc. with more comfort, safety, and fitness to the human body.Therefore, this thesis not only successfully employs computer tomography toobtain accurate data of human body, but also applies this technology to art design. Inthe mean time, this is also a tentative and beneficial attempt in modern medical field.
