The application discloses a
transcranial magnetic stimulation navigation calibration
system and a control method, a control device and a medium thereof, relates to the technical field of
medical rehabilitation, and comprises a treatment
paddle and a calibration structural member installed on the treatment
paddle. A fixed spatial offset relationship exists between the geometric center of the visual mark of the calibration structural member and the stimulation function center of the treatment
paddle. According to the spatial offset relationship, the visual mark
pose recognized by each depth camera is converted into a first
pose of the stimulation function center in the corresponding depth camera coordinate
system, instead of being based on the approximate
estimation of the paddle surface geometric center, so that the offset error between the stimulation function center and the paddle surface geometric center is avoided, and the calibration accuracy of the stimulation function center of the treatment paddle is improved. Meanwhile, the
spatial transformation relationship between the depth camera coordinate
system and the mechanical arm base coordinate system is independently calculated for each depth camera. In combination with the
spatial transformation relationship and the spatial offset relationship, each depth camera establishes an independent calibration link, does not depend on the synchronous work of multiple cameras, and meets the demand of a complex scene with frequent
occlusion in clinical application.
