本发明的另一实施例，通过获取人体整体三维模型，在确定所述颅骨三维模型的六视基准面的前提下，建立了人体的标准坐标，进而衍生到建立所有骨骼的相对坐标，实现脊柱、骨盆、下肢、上肢、胸 骨、锁骨、肋骨等骨骼的几何建模和数学建模，并通过模型以及相对坐标为基础的数据换算，实现骨骼的测量评估结构换算标准化、科学化，智能化，数据化，为生物力学在每一块骨骼之间的坐标的推演打下科学的基础。
进一步的，本发明的另一实施例通过人体骨骼的建模建立人体的标准坐标系，在这样的坐标系基础上再进行大脑、血管、神经、肌肉和内脏中任一项或者多项的建模，从而通过以上建模和标准坐标系与相对坐标系之间的结合，衍生出来正向算法与逆向算法，这样就能够实现精准定位骨骼与大脑、神经、血管、肌肉、内脏等之间的位置距离关系，让这些人体组织形成一个完整的全局科学测量体系，实现人类数字人的组织结构融合下的数字孪生。
更进一步的，骨骼与大脑、神经、血管、肌肉、内脏等之间的位置距离关系以及后续针对该人体的医疗方案和医疗效果可以作为分析数据源存储进入云服务器，基于大数据对每个人体对应的所述分析数据源进行分析，确定并获取相对位置距离关系、医疗方案以及相应的医疗效果的关系函数，以通过所述关系函数为依据进行医疗诊断和分析。
