                  此项研究的具体目标包括:

                  • 通过模拟人体表征的分辨率、成帧速率、采集精度以及对比度等细节,确定3D光学摄像机在采集人体视图时的最佳性能与太空环境可行性。
                  • 探索并确定3DO在全身成分(肌肉、脂肪、脂肪百分比、BMD)、特殊区域(内脏脂肪、皮下脂肪、腰椎BMD)以及自动人体测量学(消除姿势影响、受限视图扫描与分析等)的准确性与精度,并将结果与标准方法(DXA与高分辨率3DO)进行比较。
                  • 明确3DO身体成分与自动人体测量学方案的精度水平与精度上限,利用其他替代性条件(姿势、姿态、反重力、反向靴)、浮力(水下)以及微重力(蹦床顶点)掌握太空环境对测量造成的影响
                  • 构建并描述原型设计方案在微重力条件下的性能表现。
