The present disclosure provides a method for generating a 3D digital model used in hairpiece manufacturing is provided, which comprises: obtaining an initial 3D model of a head; identifying an outline of a target area to be covered by a hairpiece on the initial 3D model; and cutting the initial 3D model based at least partially on the target area to obtain a refined 3D model. A physical mold used in hairpiece manufacturing and a method for generating the same are also provided according to other aspects of the present disclosure.

Method for generating 3D digital model, physical mold used in hairpiece manufacturing and method for generating the same

A method for generating a 3D digital model used in hairpiece manufacturing is disclosed, which comprises: scanning a 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; generating a 3D model of the head based on the 3D geometry and color information; identifying a target area to be covered by a hairpiece based on the color information; and obtaining position of the target area based on the positional correspondence between the 3D geometry and the color information. A system for generating a 3D digital model used in hairpiece manufacturing is also disclosed, which comprises a 3D optical scanner and an electronic device.

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

A method for generating a 3D digital model used for creating a hairpiece are disclosed. The method comprises: obtaining a 3D model of a head, the 3D model containing a 3D surface mesh having one single boundary and color information associated with the 3D mesh; mapping the 3D model into a 2D image in such a manner that any continuously connected line on the 3D model is mapped into a continuously connected line in the 2D image, the 2D image containing a 2D mesh with color information applied thereto; displaying the 2D image; identifying a feature in the 2D image based on the color information; and mapping the identified feature back onto the 3D model. A system for generating a 3D digital model used for creating a hairpiece is also provided in another aspect of the present disclosure.

Method and system for generating a 3D digital model used for creating a hairpiece

A system for simultaneous real-time three-dimensional geometry and color texture acquisition. The system includes a system processor for generating at least three phase shifted black and white fringe patterns with a phase shift of 2 &#x3c0;/3, a light projector adapted to project the fringe patterns onto an object, the projector being electrically connected with the system processor, and a color camera for capturing the fringe patterns to generate at least three raw fringe images. The fringe images are used to calculate a black and white texture image which is further converted to a color image by employing a demosaicing algorithm. The fringe images are also used to calculate a wrapped phase map that is further processed to generate a continuous unwrapped phase map by employing a phase unwrapping algorithm and the unwrapped phase map is converted to co-ordinates using calibrated system parameters for point-by-point three-dimensional shape measurement.

Simultaneous three-dimensional geometry and color texture acquisition using single color camera

A method and associated apparatus for capturing an image of a 3D object () which encodes the surface geometry of at least a portion of the object, comprising: 1. projecting () a plurality of fringe patterns (A,A) onto the object; 2. capturing () phase alterations in reflections of the fringe patterns (B,B) from the object; 3. projecting a uniform image (A) onto the object; 4. capturing a reflection of the uniform image (B) from the object; and 5. combining () captured phase alterations and captured uniform image reflection on a pixel-by-pixel basis, thereby forming a holoimage representation of the object.
