Method for generating a 3d digital model, used in hairpiece manufacturing

A system for generating a 3D digital model used in hairpiece manufacturing, comprising:

• a 3D scanner, for scanning a subject's head and obtaining 3D geometry and color information of the head, the 3D geometry and color information having positional correspondence therebetween;
• and
• an electronic device, which receives the 3D geometry and color information, and is configured to:
• generate a 3D model of the head based on the 3D geometry and color information;
• identify a target area to be covered by a hairpiece on the 3D model based on the color information;
• and
• obtain position of the target area on the 3D model based on the positional correspondence between the 3D geometry and the color information.

A method for generating a 3D digital model used in hairpiece manufacturing, comprising:

• putting on a subject's head an elastic cap, which wraps on and conforms to the head;
• marking an outline of a target area, which is to be covered by a hairpiece, with visible indication on the elastic cap;
• scanning the subject's head three-dimensionally by optical means, and obtaining 3D geometry and color information of the head, the 3D geometry and the color information having a positional correspondence therebetween;
• and
• generating a 3D digital model of the head based on the 3D geometry and color information.
