The present invention discloses a camera-based Transcranial Magnetic Stimulation (TMS) diagnosis and treatment head modeling system, including a 3D scanner, a positioning cap, and a smart terminal, where the 3D scanner and the smart terminal are electrically connected. A modeling method for the head modeling system includes: acquiring 3D image data of the head of a patient by a camera from different directions, and integrating the image data to obtain complete 3D image data; and then mapping, in combination with MNI brain space coordinates, a skull model obtained by brain 3D scanning in an MNI space to 3D head model data of the patient to obtain a head model highly matching the real head of the patient. Thus, the accuracy of subsequent positioning of a magnetic stimulation point for magnetic stimulation on the head of the patient is improved, and the TMS magnetic stimulation treatment effect is greatly improved. In the present invention, a head model of a patient can be obtained by only acquiring 3D data of the head of the patient by a 3D camera and processing the acquired data through a smart terminal. The cost is low, the operation is simple, and the degree of automation is high.
