| description | The embodiment of the invention provides an oral cavity image registration method and device, electronic equipment and a computer storage medium. The method comprises the following steps: acquiring a first three-dimensional image obtained by scanning an oral cavity by cone beam computed tomography equipment and a second three-dimensional image obtained by scanning the oral cavity by intraoral scanning equipment; performing local registration on the first three-dimensional image and the second three-dimensional image, and screening position points of a grid region in the second three-dimensional image according to a local registration result; according to the corresponding position points of the position points of the tooth area in the first three-dimensional image, determining a pixel threshold value, performing three-dimensional surface drawing processing on the first three-dimensional image according to the pixel threshold value, and determining the position points used for global registration in the grid a |
