Abstract
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.
