METHOD AND DEVICE OF DETERMINING A POSE OF A SURGICAL REGISTRATION DEVICE

A method, a surgical registration device (2), a sensor device (6), a system, a computer program, a computer-readable medium and a data carrier signal are disclosed. The surgical registration device (2) comprises a surface, an optical pattern (30) on the surface, and an interface unit to attach to a tracking system (4). The method comprises obtaining (70) an image of the surgical registration device, detecting (72) the at least one optical pattern in the image, obtaining surface (74) model data describing the surface, obtaining (76) a location of the optical pattern with respect to the surface, determining (78), based on the detected optical pattern, the surface model data and the location of the optical pattern, a second pose of the surface, obtaining (80) depth information describing three-dimensional coordinates of the surface and determining (82), based on the second pose, the surface model data and the depth information, a third pose of the surface of the surgical registration device. 公开了一种方法、手术配准设备(2)、传感
