摘要
手术导航注册是实现手术导航、器械跟踪的关键技术。提出了一种基于深度相机的手术导航注册算法,结合点云配准的相关原理,构建PCA点云坐标系,提高了粗点云配准的速度,结合CPD精配准算法,完成手术导航注册,通过实验验证了该方法的有效性。
Surgical navigation registration is the key technology in the surgical navigation and instrument tracking.In this paper,a surgical navigation registration method based on depth camera is proposed.According to the relevant principles of point cloud registration,the PCA point cloud coordinate system is constructed,which is used to greatly improve the speed of coarse point cloud registration,and the CPD fine registration algorithm is used to complete the surgical navigation registration.The effectiveness of this method is verified by experiments.
