Abstract:

The body contour extracted from the images of front and side body taken by digital camera is used in technology of automatic 3-D body measurement. This technology suits with business because of its low technical cost, simple and fast computing process. (The generic method is to estimate the size by analyzing the circumference of examples and getting the model constrained by the circumference’s width and thickness which is a function with curve fitting.) This paper discusses the models about the deviation and curve’s shape. The models are fitted by exponential, logarithm, quadratic polynomial and cubic polynomial functions. The models’ rationality and disadvantages are demonstrated, providing a reference to make more appropriate models for measuring body circumference.
