TMS head movement detection method

The invention discloses a TMS head movement detection method, which comprises the following steps of: s1, scanning to obtain a magnetic resonance image of a patient, and obtaining a head depth image and an rgb planar graph of the patient through a depth camera; s2, obtaining a three-dimensional coordinate corresponding to a face feature pixel point according to a corresponding relation between the head depth map of the patient and the rgb plane map of the patient; s3, realizing three-dimensional reconstruction of the magnetic resonance image obtained in the step s1 by using a marking cubes surface drawing algorithm in combination with a Vtk toolkit; s4, using an MTCNN algorithm to obtain two-dimensional coordinates of face feature pixel points of the two-dimensional screenshot; s5, calculating three-dimensional coordinates of the face feature pixel points obtained in the step s4 in a Vtk world coordinate system according to a Vtk coordinate system conversion relation; and s6, carrying out affine registration
