Scanning method and system of scanning rod, and storage medium

A scanning method of a scanning rod, applied to a scanned scene with scanning rods, comprising:

• scanning a scanned scene in a first scanning rod assembling status to obtain first scanning data, wherein scanning rods are assembled at a third assembly site and a first assembly site in the first scanning rod assembling status;
• scanning the scanned scene in a second scanning rod assembling status to obtain second scanning data, wherein the scanning rods are assembled at the third assembly site and a second assembly site in the scanned scene in an oral cavity in the second scanning rod assembling status;
• and
• obtaining position information of the assembly sites in the scanned scene based on the first scanning data and the second scanning data;
• wherein the method further comprises:
• acquiring a display image based on the first scanning data;
• when scanning the scanned scene in the second scanning rod assembling status, cancelling data of the scanning rod corresponding to the first assembly site in the display image, and scanning the scanning rods at the second assembly site and the third assembly site to obtain the second scanning data;
• and
• updating the display image based on the second scanning data.
