摘　　要：为实现基于三维人体点云的人体形态相似性匹配,文章提出了利用角度半径进行青年男体躯干部轮廓形态描述的方法。先以187名18~25周岁的青年男大学生为研究对象,使用三维扫描法获取其三维点云数据。再通过逆向工程软件识别人体躯干部特征点,截取其正侧面躯干轮廓形态。然后分别建立正侧面躯干部坐标系,提取27个正面角度半径值和60个侧面角度半径值形成三维点云躯干形态数据库。选取14名被试者进行验证,提取的正、侧面角度半径为样本,采用均方根误差法与点云截面数据库进行匹配,并使用OpenCV框架中的MatchSharp法验证匹配结果。结果显示,13名被试者的躯干部正侧面轮廓形态与三维点云轮廓形态匹配成功,准确率达92.86%。研究结果可为三维点云形态相似性分析提供一定的理论基础。With the continuous development of the world economy and people’s living level,the demand for clothing comfort and fitness has become increasingly prominent.In the process of online clothing consumption,it is difficult for consumers to try on and choose suitable clothes.How to analyze the human body shape quickly and accurately is an urgent problem to be solved.Increasing attention has been paid to non-contact two-dimensional anthropometry,with the recognition and matching of human body contour being the key research direction.Many domestic and foreign scholars have carried out substantial studies,and put forward a variety of methods such as RBF neural network,cubic spline function,least square method and Fourier coefficient,but these methods can not fuzzy match the human body shape.The shape context method has also been used for shape matching.Although this method can improve the accuracy and speed of matching,it is still difficult to match human form with the shape context.Therefore,this study focused on how to describe human body contour shape quantitatively based on three-dimensional point cloud data of human body.An angular radium-based contour description method was proposed.One hundred and eighty-seven young male college students aged 1825 were selected as research objects,and three-dimensional point cloud data were obtained by three-dimensional scanning method.Then the reverse engineering software was used to identify the feature points of the human trunk and intercept the silhouette of the front and lateral trunk.The frontal and lateral trunk coordinate systems were established respectively,and 27 frontal and 60 lateral angular radii were extracted to establish the frontal and lateral trunk form angular radii database based on three-dimensional human point cloud.In order to obtain the human body with a similar shape,the angular radius was used as the reference to judge whether the cross-section shape of the characteristic parts was consistent,and the similarity was quantified by the root mean square of
