Abstract: This paper maked a breakthrough of the traditional mode of the garment parameterization pattern method.Taking the prototype women′s garment as the study object,the BP neural network was trained and verified with Java.The simulation results indicated that this algorithm was similar with our brain on making garment pattern.And this paper used the method of parametric coordinate which differs from those of extracting the length of pattern in the past.In this way,it was easier to extract the data from the pattern and to make transfer between them.These coordinate data express good data-correlation in the training of BP neural networks.
