[0066] The specific implementation of the method of the present invention will be further described below.
[0067] The method of the present invention comprises the steps of:
[0068] Step 1, geometric restoration of the ancient human skull:
[0069] Step 1.1, extraction and modeling of the point cloud of the outer surface of the ancient human skull:
[0070] 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;
[0071] 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 take the z-axis in the Frankfurt coordinate system as the long axis of the cylinder and the cylindrical surface with r as the radius to perform equidis...
