Visual Measure Of Human Body Base On Custom-Made Clothes

Non-contacting body measurement is the main feature of modernization body measurement technology. This paper analyzed all kinds of untouched body measurement systems domestically and abroad; the common obstacles faced to them are high cost, complicated installation, large space and dark room requirement etc. To these problem, we developed Untouched Body Measurement System, it is a natural light-based system, and use single CCD camera. This system takes the body images as the carrier of diction and transmission, draws the useful 2D anthropometrical information. 3D body actual measurement can obtain through mathematic models of body individually.The main contents of this paper touch on edge of body digital image, recognition the pivotal points and lines of body, 2D-3D conversion of measurement information and much systematic works. At last, the software designs of this system accomplished.Above all, the paper put forward a new method to detect edge of body that came from image segmentation theory based on wavelet-transform. For eliminating the influence disturbed by environmental factors, edge threshold function is conceived, which can adjust automatically according to exposal of digital image. So, the system can detect the edge of body effectively.Secondly, the paper analyzed pivotal points and lines of body and concluded five systematic identifying methods to gain the 2D information of body digital image. They are curvilinear-knaggy-point recognition, extremism recognition, modeling recognition, curve line fitted recognition and approximate arithmetic of curve length.Thirdly, the initial parameters confirmed by system calibration, such as amplificatory ratio K0 of referenced plane, the movement of calibration, such as object distance H etc. So, you can get the actual measurements of body after suitable transform. We also established lay depth Z formulas bust and hop circumference and 2D-3D mathematic models of head, neck base girth and thigh circumference. So, 2D digital image information can be transacted by geometry distortion rectifying and perspective & projective image transformation, and 3D body actual measurement can obtain used mathematic models of body individually.The whole system programming language is vc++. We adopt the structure of user interface + MySql database.
