摘　　要：针对中国数字人的断面切片图像,建立肩部骨骼肌肉包括皮肤的三维模型。按照图像数据集的获取与配准、预处理、三维重构的流程。采用基于拐点的精度可调的轮廓拼接三维重构算法,通过轮廓比对找出相对正确的匹配关系,对中国数字人肩部结构进行三维重建和几何保存。结果获得了肩部骨骼和肌肉包括皮肤的结构的重建,并可以进行任意角度观察,可以调整任意某结构的透明度,清楚显示肩部骨骼肌肉等三维位置关系。结果提示,基于轮廓拼接算法的三维模型在结构上与原真实标本误差小,为进一步的人体个体化研究奠定了基础。3D anatomical model of human shoulder muscles, bones and skin was established based on the sections of Chinese Digital Human （Male）. The whole process included acquiring, matching, pretreatment and 3D reconstruction. To reconstruct and save 3D model of human shoulder, the calculating method of matching the outline of Chinese Digital Human body, of which the accuracy was adjustable, is explored. The reconstructed model, displaying the structure of shoulder muscles and bones, can be observed in any angle and at any level of transparency. The error in the model based on 3D contour matching is small. This model lays a foundation for future individualized researches of human body.
