More Information
Summary:The invention provides an automatic registration method for an SERF atom magnetometer and a head nuclear magnetic resonance image, and the method comprises the steps: obtaining the three-dimensional information of the head of a testee based on an optical scanner, and segmenting a scanning point cloud into a helmet part and a human face part; performing coarse registration on the helmet model and the helmet point cloud based on the FPFH descriptor, performing fine registration by adopting an ICP algorithm, and determining the position and direction of the sensor on the three-dimensional scanning data; and performing coarse registration on the face point cloud and the head nuclear magnetic resonance image based on face symmetry information, performing fine registration by adopting an ICP algorithm, and converting sensor position and direction information to a nuclear magnetic resonance image coordinate system. The registration algorithm realized by the invention has the characteristics of automation, high preci
