河南省青年男性标准体手臂尺寸测量及分析

Measurement and Analysis of Arm Size of Young Male Standard Body in Henan Province

文章针对河南省青年男性标准体的手臂尺寸,并对比手工测量和三维扫描两种测量方式的差异。发现手工测量和三维扫描的测量数据基本上均服从右偏正态分布,两种方法测得的各项指标间的相关性一致。手工测量和三维扫描的测量结果普遍存在着显著性差异,手工测量值普遍大于三维扫描测量值。对于自行设计的测试指标,当样本量充足时,手工测量的精确性更高。

The paper analyzed the differences between manual measurement and three-dimensioual scanning method of the arm size data of the standard body of young men in Henan Prevince.It was found that the manual measurement and three-dimensional scanning measurement data basically obeyed the right-skewed normal distribution.And the correlations among different indexes tested by two methods were consistent.Generally,there were significant differences between the manual measurement data and three-dimensional scanning data,and the testing results of manual measurement method were larger than that of the three-dimensional scanning method.For the self-designed test indexes,the accuracy of manual measurement would be higher when the samples size were enough.
