Embodiment Construction

[0067] The specific implementation of the method of the present invention will be further described below.

[0068] The method of the present invention comprises the steps of:

[0069] Step 1, geometric restoration of the ancient human skull:

[0070] Step 1.1, extraction and modeling of the point cloud of the outer surface of the ancient human skull:

[0071] Step 1.1.1: Manually calibrate the left ear hole, right ear hole, left orbital infraorbital edge point and brow point on the ancient human skull model, so as to establish the Frankfurt coordinate system, and adjust the ancient human skull model to the Frankfurt coordinate system to realize the model posture Correction;

[0072] Step 1.1.2, calculate the bounding box box={x of the 3D model of the ancient human skull min ,y min ,z min , x max ,y max ,z max}, and then use the Z-axis in the Frankfurt coordinate system as the long axis of the cylinder to perform equidistant cylinder sampling, then the sampling point p...

Abstract

The present invention relates to a craniofacial interactive restoration method of ancient human skulls based on the soft tissue distribution of modern humans, specifically comprising the following steps: step 1, geometric repair of ancient human skulls; step 2, registration of ancient human skulls and modern human skulls; Step 3, craniofacial restoration based on the soft tissue distribution of the reference model; Step 4, construction of a candidate dataset of craniofacial restoration results; Step 5, interactive craniofacial restoration based on the statistical shape model. The beneficial effects of the ancient human skull craniofacial interactive restoration method based on the distribution of modern human soft tissues: improve the accuracy of the craniofacial restoration method based on skull registration; improve the accuracy of the ancient human skull craniofacial restoration results; improve the craniofacial restoration. The accuracy of surface restoration results.

Description

technical field [0001] The invention relates to a method for craniofacial restoration of human skulls, and more specifically, a method for interactive restoration of craniofacial skulls of ancient humans based on the distribution of soft tissues in modern humans. Background technique [0002] What did human ancestors look like, and how to use craniofacial restoration technology to restore the appearance of ancient human skulls is one of the hot issues that anthropologists are concerned about. There is a correlation between the geometry of the skull and the face, and the geometry of the skull determines the geometry of the face. Therefore, this problem can be solved by using the restoration of the skull face. Skull facial restoration is based on the distribution of soft tissues of the human head and face and the morphological relationship between the skull and facial features, using plastic substances on the plaster model of the skull or skull, such as plasticine, clay, wax, ...
