Embodiment Construction
[0049] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0050] Such as Figure 1 to Figure 9 Shown, a kind of oral cavity CBCT image and the data fusion method of laser scanning tooth mesh, comprise the following steps:
[0051] Step 1: Read the CBCT image and scan tooth mesh model data
[0052] Read the 3D DICOM image sequence data obtained by CBCT scanning, as well as the tooth mesh model scanned by laser;
[0053]Step 2: Reconstruct the skeletal mesh model of the head with teeth from the CBCT image
[0054] Firstly, the mesh containing the tooth part is reconstructed from the CBCT image, and the alignment of the CBCT image and the tooth part of the scanned mesh model is transformed into the alignment of the reconstructed mesh model and the tooth part of the scanned tooth model. Specifically, the MarchingCubes method is used to extract the isosurface grid (Isosurface) from the CBCT image, and the head bone me...
