This invention concerns an automated registration method and device for a surgical robot enabling registration between a first three-dimensional location system comprising an optical distance sensor and a second three-dimensional location system comprising optical acquisition means. The method comprises: a first step of intraoperative registration between the first location system and data recorded on an anatomical surface of a patient and; a second step of intraoperative registration of two three-dimensional location systems. The second registration step is performed at the same time as the first registration step by detection, by the optical acquisition means, of at least one point of a point cloud acquired by the optical sensor during the first intraoperative registration.
Automated registration method between two three-dimensional location systems used in robotic surgery in order to match up location data from separate frames of reference belonging to each system, a first three-dimensional location system comprising an optical distance sensor and a second three-dimensional location system comprising an optical acquisition means, said method comprising:
Automated registration method between two three-dimensional location systems according to the preceding claim, wherein the second registration step involves calculating a transfer matrix between the two frames of reference of the two three-dimensional location systems (2, 10).
An automated registration system comprising:
