[0092] S115: When the scanning head dynamically scans the damaged part of the user, scanning data corresponding to the damaged part is collected in real time, and multiple scanning data are screened online to exclude abnormal scanning data.
[0093] In an embodiment of the present application, the user's area to be detected is located, and the damaged portion of the user is marked based on the user's traversal of the area to be detected, so as to facilitate further control of the user's area to be detected, thereby introducing the damaged portion of the user and processing the damaged portion of the user. Optionally, the user's area to be detected is the area of the user that needs to be detected, and the damaged portion of the user is the portion of the user that has been damaged by an external object.
[0094] At this time, the orientation of the damaged part of the user and the position of the scanning head are collected, and the orientation of the damaged part of the user and the position of the scanning head are controlled as a whole, so as to define the relative position according to the position of the damaged part of the user and the position of the scanning head.
