US Patent 11295538 Method and equipment for constructing three-dimensional face model

A three-dimensional face model constructing method includes: obtaining front face information to establish a three-dimensional front face model and generate a front planar image corresponding to the three-dimensional front face model, wherein the front planar image includes first feature points; obtaining full face information to establish a three-dimensional full face model and generate a full face planar image corresponding to the three-dimensional full face model, wherein the three-dimensional full face model includes a specific portion and the full face planar image includes second feature points; superimposing a first block of the front plan image to a second block of the full face planar image according to the correspondence between the first feature points and the second feature points, to obtain a complete full face planar image; and generating a three-dimensional face model according to the complete full face planar image.
