The Research And Implementation Of Human Body Measurement Based On 3D Body Model Reconstruction

For the past few years,with the development of the society,people's material wealth has enriched a lot,and they also ask for higher demands of life.According to the sizes of the constituents of the human body,clothes are made and designed.The data of body figure has an important status in the design and production of clothing,these data provides an important basis for clothing size charts in clothing design.Foreign countries are constructing and perfecting their own databases of human body shape actively and gradually all the way,and nowadays have complete and authoritative databases relatively.Compared with foreign countries,internal started late,and is now in beginning stage,these restrict the development of clothing industry.With the development of mobile internet,mobile terminal has become an essential item.It has integrated more and more functions,and almost has no limit with other special equipment,e.g.computer and camera,and it is even going to be their replacement.With the HD camera of mobile achieving body data,it doesn't need professional measuring system,and also can get relative accurate data.So we can try the technique.This article based on the background above,has studied 3D human model reconstruction through two-dimensional images and compute several important parameters,finally,set up a platform of anthropometric measuring,and it can apply to estimate body parameters for users.Solving the problems above:1.Image obtaining.Through mobile camera,or ordinary digital camera,take multi-angle images.2.Image preprocessing.Using image size normalizing and grayscale adjustment;image smoothing and image sharpen.3.Multi-images feature points extraction and matching.SIFT feature points extraction and matching algorithm.4.Based on feature points 3-demensional reconstruction.Firstly,research two images match based on epipolar geometry,and then enlarge to multi-images reconstruction.5.Human body dimensions' key parameters measurements.Using the 3D reconstruction model,based on cubic spline interpolation compute human body key parameters.6.The human body measurements platform based on HTML5.Develop a measurements platform on mobile end system,and this platform can realize key parameters measurements of human body through users film several photos.
