摘　　要：研究人体身型特征的身份识别,提高身份准确性问题。针对传统的人体身份识别技术,都是用直线距离近似表示人体身型的几何特征,但是人体身型中的大部分真实几何特征距离都是空间曲线距离,会导致测量的身型几何特征结果不够精确,造成后期的身份识别准确性不高的问题。为了解决上述问题,提出一种基于近似曲线几何特征的身份鉴定方法,运用近似曲面分割逼近技术,求出人体身型几何特征点之间的最短近似路径,运用多个最短路径逼近方法,准确获得人体真实的身型几何特征信息。实验结果表明,改进的方法能够准确提取三维人体身型几何特征,使得身份识别准确率大幅增加。Study the body characteristics identification, and improve the accuracy of the identification. In traditional human identity recognition technology, a straight line distance is used in to approximate the curve of the human body model, but most real geometry characteristic distance of human body is space curve distance, leading to the Iowa precise of traditional methods of measuring body. In order to solve this problem, the paper proposed a kind of approximate curve based on geometric feature identification method, using approximation technology of approximate surface to work out the shortest approximate path between the geometric feature points of human body. Shortest path approximation method was, accurate used to get the real geometry characteristic information of human body. The experiment results show that the method can accurately extract 3D body geometric features, which makes the identification more accurate.
