Abstract:

A three-dimensional geometric database was established for Chinese child body shape in seated posture based on Microsoft's Kinect scanning device and other algorithms. The database used a sitting scanning experimental platform of the second generation of Microsoft's Kinect to collect various characteristics
with different percentiles of sitting posture models from 89 children volunteers at the ages of 6~12. A human body model processing program written in C++ was used for the acquired models to perform some processes such as smoothing and de-noising. The obtained two-dimensional and three-dimensional data were integrated and processed by using software Microsoft Access 2016. The results scanned from children volunteers show that the length average error of the human body model is 6.6 mm with high precision and high credibility. Therefore, the three-dimensional geometric database can be used as a data foundation of research, design and development of Chinese products such as child seats.
