[0002] With the development of science and technology, virtual face fabrication technology is gradually mature, and the virtual face fabrication technology is widely used in many industries. In the application of virtual face fabrication technology, the staff needs to first perform 3D scanning on a model through a scanning device, and reconstruct the scanned image on a computer. The staff then modifies the scanned face for use, so the scanning device is an indispensable device in virtual face fabrication.

[0003] For example, the existing document CN209310732U discloses a 3D model scanning device, which comprises a scanning device body, the scanning device body comprises: a storage box; a base is arranged on one side of the storage box, a rotating shaft is installed on the top of the base, a fixing seat is sleeved on the top of the rotating shaft, and a scanner is installed on the top of the fixing seat; a support seat is arranged on the top of the storage box and is provided with a placing groove on the top, a placing cavity is formed in the support seat, a gear one is arranged in the placing cavity, a connecting rod is fixedly arranged on the top of the gear one, the top end of the connecting rod penetrates through the placing groove, and a placing table is installed on the top end of the connecting rod; and a protective cover is arranged on the top of the support seat and forms a space opening towards the scanner with the support seat, a driving mechanism is arranged on the side of the protective cover which is closed, and the driving mechanism is used for driving the gear one. The 3D model scanning device can perform omnidirectional scanning on an object and change the scanning range and the scanning direction.

[0004] Although the scanning device in the above document can effectively scan a model, the scanning device has the following deficiencies in actual use.

[0005] 1. The existing scanning device always maintains a certain angle of scanning state, and when the top or bottom of the model is scanned, the scanning device is difficult to directly scan due to the change in the angle of the model. At this time, the computer automatically fills in the original scanning data to complete the entire virtual face component, but such a scanning method is difficult to fully reflect many details of the model, thereby leading to poor authenticity of the scanned face.

[0006] 2. The existing scanning device is fixed as a whole when in use, and cannot be adjusted in distance according to the size of different models, which leads to the deficiency that the scanned model is unclear.

[0007] 3. The existing scanning device is used, and the staff directly places the model on the scanning table, and then the staff starts the scanning device to scan the model on the scanning table. Such a scanning method cannot be applied to real person portrait scanning, and the practicality is narrow.
