The invention relates to a brain magnetic measurement device and a method for registering the brain magnetic measurement device and MRI (Magnetic Resonance Imaging), and belongs to the field of brain magnetic research. The method comprises the following steps: acquiring a head image of a testee wearing a brain magnetic measurement device; performing point cloudization on the head image of the testee to obtain a scene point cloud; performing corresponding point clustering processing on the scene point cloud and the identification module model point cloud, identifying the identification module and determining the position coordinate of the identification module; determining the position of the sensor probe according to the position coordinates and the relative position relation between the identification module and the sensor array; acquiring a three-dimensional MRI image of the head of the subject, and separating the three-dimensional MRI image into a scalp three-dimensional image and a cerebral cortex anatomi
