摘要：

针对人体点云模型特征点和尺寸自动提取的难点问题，提出基于国家标准统计数据的人体关键尺寸提取技术。采用国家标准GB100001988《中国成年人人体尺寸》所提供的基础数据划分特征点的搜索域，首先，在搜索域内将坐标值和点到直线投影距离比较相结合来提取人体特征点；然后通过改进的凸壳法计算特征平面轮廓周长进行围度尺寸测量，再利用z坐标差值和两点的距离实现长度尺寸计算。实验表明，该方法受人体体型的影响小，尺寸测量鲁棒性好、计算速度快、精度高。

Abstract:

Aiming at the difficult problem of automatic extraction of human feature points and size from the human body cloud model, the extraction technique of key dimensions based on the national standard data is proposed. Firstly, we use the data provided by the national standard GB100001988 “human dimensions of Chinese adults” to divide the feature search domain, and, in the search domain, coordinates and points to the linear projection distance are combined to extract body feature points. Secondly, the characteristics of planar contour perimeter for dimension measurement are calculated through the improved convex hull method. Finally, z coordinate difference and the distance between two points are used to realize length dimension calculation. Experiments show that the method is little influenced by the type of human body, and has good robustness, fast calculation speed and high precision.

Key words: point clouds of human body;national institute of standards;feature points of human body;anthropological measurement
