Problems solved by technology

[0006] The above method is simple and efficient to implement, but the restoration process is only based on the soft tissue thickness at the feature points, and the number of feature points is usually very small, making it difficult to represent a face with rich details, so the restoration accuracy of the above method is low

Embodiment Construction

[0029] In order to make the technical solution of the present invention more clear and understandable, the solution of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] figure 1 It is a flowchart of an embodiment of the craniofacial restoration method of the present invention. Such as figure 1 As shown, the following steps 11-13 are included.

[0031] Step 11: Construct a three-dimensional craniofacial database, which includes at least N craniofacial samples, where N is a positive integer greater than 1, and each craniofacial sample includes: a craniofacial composed of a three-dimensional skull model and a three-dimensional face model model, and the properties corresponding to the craniofacial model.

[0032] Step 12: Synthesize the N craniofacial samples, and determine the relationship between the 3D face model, the 3D skull model and the attributes.

[0033] Step 13: Obtain the 3D skull mode...

Abstract

The invention discloses a craniofacial reconstruction method comprising the following steps: building a 3D craniofacial database, wherein the 3D craniofacial database at least includes N craniofacial samples, N is a positive integer greater than 1, and each craniofacial sample includes a craniofacial model composed of a 3D skull model and a 3D face model as well as the attribute corresponding to the craniofacial model; determining the association relationship between the 3D face models and the 3D skull models and the attributes based on the N craniofacial samples; and acquiring a 3D skull model to be reconstructed and the corresponding attribute thereof, and reconstructing a 3D face model corresponding to the 3D skull model to be reconstructed according to the association relationship. By using the method of the invention, the reconstruction precision can be improved.

Description

technical field [0001] The invention relates to computer application technology, in particular to a craniofacial restoration method. Background technique [0002] Craniofacial reconstruction refers to the scientific prediction and restoration of the unknown face of a given skull according to the morphological laws of the skull and face. It has always been an important research topic in the fields of forensic science and anthropology. [0003] Craniofacial restoration originated in Europe and has a history of more than 100 years. The traditional craniofacial restoration method is manual craniofacial restoration. Manual craniofacial restoration requires complex techniques, the restoration process takes a long time, and the restoration process is highly subjective. These defects have greatly restricted the application of manual craniofacial restoration. [0004] At present, computer-aided craniofacial restoration methods are widely used, and the more commonly used methods incl...
