Validity Analyses of an Anthropometric Method Based on Computer Graphics

摘要

A comparative survey was conducted with 163 Chinese male pilots to build an anthropometric method based on computer graphics. 10 human body dimensions of point-to-point distance were gathered by extracted measurement based on computer graphic and traditional measurement in ISO7250 techniques. It was found that the extracted measurements were homogeneous with the traditional measurements in standardized Z scores, but there were systematic errors in raw data of the anthropometric method based on computer graphics. It suggested that the methodology based on computer graphics was well acceptable in views of ISO20685 because all mean differences were less than ±1.0 mm in 95% confidence interval after data correction by linear equation. Some factors were also discussed.
