摘要：

       基于微软的Kinect 扫描设备和相应算法软件，建立了一个中国儿童人体坐姿的三维几何数据库。该数据库使用第二代微软的Kinect 所搭载的坐姿扫描实验平台，采集各种特征( 年龄在6~12 岁之间的各百分位) 的89 个儿童志愿者的坐姿模型；对这些所得模型，使用C++ 编写的人体模型处理程序，进行光顺、去噪等算法处理；使用Microsoft Access 2016 软件，对于所得的二维及三维数据，整合处理。对这些儿童志愿者的扫描结果表明：该人体模型的长度平均误差为6.6 mm，精度较高, 可信度较高。因此，可用于儿童座椅等中国产品的研究、设计和开发的数据基础。

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.
