In facial digital modeling, machines can be used in scanning devices, such as 3D scanners, to convert the shape and details of facial surfaces into digital data. These digital data can be represented as three-dimensional models for analysis and processing, such as face recognition, virtual reality and so on.
On the other hand, in applications related to face digital modeling, machines can also be related to hardware devices. For example, mechanically constructed robots, mechanical arms, etc. It can be used to extract key information from face images or videos to help face digital modeling. These mechanical devices can realize digital face reconstruction through mechanical movement and visual acquisition according to preset algorithms and models.
To sum up, although machinery is related to face digital modeling, it is not a necessary condition. Digital face modeling focuses more on the application of computer vision technology and computer graphics. In this process, the machine may appear as a part of data acquisition tools or related hardware equipment.
