基于生物不变特征的数字物理耦合方法

Digital-physical Coupling Method Based on Biological Invariant Characteristics

增强现实在医疗中的应用能有效提高医生的空间感知能力,其中的一个关键步骤就是数字模型与患者的耦合。提出一种基于生物不变特征的数字物理耦合方法,该方法利用人体特征的不变性,在数字模型和患者身体的相同特征位置放置标记点,最终通过两组标记点的转换实现自动耦合。在人体模型实验中仅使用少量的标记就能实现耦合,并具有较低的误差。

The application of augmented reality in medical treatment can effectively improve the doctor's spatial perception ability.One of the key steps is the coupling of the digital model and the patient.A digital-physical coupling method based on biological in⁃variant characteristics is proposed.The method uses the invariance of human body characteristics to place markers at the same characteristic positions of the digital model and the patient's body,and finally realizes automatic coupling through the conversion of two sets of markers.In the human body model experiment,the coupling can be achieved with a small amount of markers and has a lower error.
