A selection method of body surface sample for parametric finite element model of human body
A sample selection method for human body surface modeling is designed for accurately selecting body surface samples used for parameterization methods to build finite element models with female Chinese body characteristics.The method of population estimation based on samples is applied to determine the reasonable number of body surface samples;three statistical characteristic parameters of height,body mass index and age of body surface samples are generated by the interval estimation parameter calculation of normal distribution and the data distribution proportion;the selection parameters of each sample are generated by Latin hypercube sampling method according to the distribution of statistical characteristic parameters of body surface samples;Pearson correlation coefficient is employed to test the correlation between the vectors of characteristic parameters.Based on the designed generation method for body surface samples parameters,under the condition of 95%confidence and an error less than 10%,there is no significant correlation among the vectors formed by each characteristic parameter of 97 female body surface samples and the distribution of each characteristic parameter is consistent with the overall distribution.The designed selection method for body surface samples effectively selects body surface samples representing the characteristics of female Chinese.
