On the Measurement and Evaluation of Skirt Shape Infrared Ray Form Drawing

Abstract

In order to develop a method to evaluate the wearing form of skirt, we measured distances between center of body and outside skirt boundary, by the help of infrared ray form drawing device. Outline shape of skirt is thus determined and the results are treated statistically. The reproducibility of data is confirmed by 10 times measurements for each condition.
The results are as follows :
1) The distortion of skirt outline shape is so complex and the 95% level confidence interval of original data is so broad, that we decided to use moving average method to analyze the shape of skirt.
2) The 95% level confidence interval of data by moving average method is narrow enough. to evaluate the outline shape, and the reproducibility of data is also good for each wearing condition.
3) When the moving average method is used, 3 to 5 measurements are estimated to be needed to obtain 5% accuracy level of reproducibility.
