    • A method and system for archiving 3D geometry information for a plurality of subjects, and on a particular part of the body (which may also be the whole body) is described. The method and system allow an organizing and an analyzing step, resulting in scalable characteristic components for the particular part of the body, and an approximation of the geometry of that particular part of the body for a specific subject by a combination of a subset of those characteristic components with corresponding scale factors, which are then stored. The method comprises the steps of : • organizing for each of said plurality of subjects the 3D geometry information according to a predetermined standard, thus obtaining organized 3D geometry information; • analyzing the organized 3D geometry information of said plurality of subjects, resulting in averaged 3D geometry information of said particular part of the body; and - scalable characteristic components of said particular part of the body; such that for each of said plurality of subjects said organized 3D geometry information can be approximated by a combination of said scalable characteristic components relative to said averaged 3D geometry information; • comparing, for at least one out of said plurality of subjects, said organized 3D geometry information with said averaged 3D geometry information and determining a subset of said scalable characteristic components and corresponding scale factors, for approximating to a given accuracy said organized 3D geometry information relative to said averaged 3D geometry information by a combination of said scalable characteristic components out of said subset, each characteristic component scaled with its corresponding scale factor; • storing, for at least one specific subject out of said plurality of subjects, said approximated organized 3D geometry information by storing - said averaged 3D geometry information; - said subset of said scalable characteristic components and said corresponding scale factors for said specific subject.
    • 描述用于归档多个对象的3D几何信息的方法和系统,以及身体的特定部分(其也可以是整个身体)。 该方法和系统允许组织和分析步骤,导致身体的特定部分的可缩放的特征组分,以及通过组合的一组子集合对特定对象的身体的该特定部分的几何形状的近似 具有相应比例因子的特征分量,然后存储。 该方法包括以下步骤:根据预定标准对所述多个对象中的每个对象组织3D几何信息,从而获得有组织的3D几何信息; °分析所述多个对象的有组织的3D几何信息,导致身体的所述特定部分的平均3D几何信息; 和 - 所述身体的所述特定部分的可伸缩特征部件; 使得对于所述多个对象中的每一个,所述有组织的3D几何信息可以通过相对于所述平均3D几何信息的所述可缩放特性分量的组合近似; °,对于所述多个对象中的至少一个,将所述有组织的3D几何信息与所述平均的3D几何信息进行比较,并且确定所述可伸缩特征分量的子集和对应的比例因子,以便近似给定精度所述有组织的3D几何信息 相对于所述平均的3D几何信息,通过所述子集中的所述可分级特征分量的组合,每个特征分量用其对应的比例因子缩放; 通过存储所述平均的3D几何信息,对于所述多个对象中的至少一个特定对象存储所述近似组织的3D几何信息; - 所述可缩放特性组件的所述子集和所述特定对象的所述对应比例因子。
