The preset interface rule area and the data writing area are sequentially arranged, such as an interface rule area 1, a data writing area 1, an interface rule area 2, a data writing area 2, an interface rule area 3, a data writing area 3, and the like. Specifically, the interface rule area is always in front of the corresponding data writing area, and after the interface rule area and the corresponding data writing area are fully written, the arranged rule data and the image data automatically form a data packet meeting the packet-forming requirement, so that fast packet forming can be performed.
And step 108, writing the data packet after the completion of the grouping into a preset frame format for encapsulation.

the second writing module is used for writing a preset interface rule into a plurality of interface rule areas preset in the memory;
the grouping module is used for grouping the image data of the data writing area and the rule data of the interface rule area;
the packaging module is used for writing the data packet after the completion of the grouping into a preset frame format for packaging;
the transmission module is used for transmitting the packaged data packet to the PC terminal;
the second writing module is specifically configured to: writing interface rules meeting the requirements of being transmitted to the PC terminal into a preset interface rule area in the memory as the preset interface rules, so that the data packet can be directly transmitted to the PC terminal;
the package module is specifically configured to:
the interface rule area is always in front of the corresponding data writing area, and after the interface rule area and the corresponding data writing area are fully written, the arranged rule data and the image data automatically form a data packet meeting the packet grouping requirement, so that quick packet grouping can be performed.
8. A computer-readable storage medium, characterized in that a computer program is stored, which, when being executed by a processor, causes the processor to perform the steps of the method of processing scanned image data as claimed in any one of claims 1 to 6.
9. A scanning device comprising a memory and a processor, the memory storing a computer program which, when executed by the processor, causes the processor to perform the steps of the method of processing scanned image data as claimed in any one of claims 1 to 6.
