8. scanner as claimed in any of claims 1 to 7 in one of claims, it is characterised in that the scanner also includes image control
Device processed, described image controller, the graphics control signals sent for receiving the main control module, and controlled according to described image
Signal controls the projecting apparatus to be projected.
9. a kind of scanner imaging method, it is characterised in that the scanner includes projecting apparatus, image acquisition device, identification module
And layered module, the scanner imaging method comprise the following steps：
The projecting apparatus is by the surface of preset projector, image projection to scanned object；
The image that described image collector is reflected the scanned object surface is acquired, and by the image of collection
Send to the identification module；
The identification module identifies the image, and recognition result is sent to the layered module；
When the image has abnormal hot spot, the layered module is projected according to the recognition result to the projecting apparatus
Image handled, to eliminate the abnormal hot spot；
The abnormal hot spot includes speck and blackening, when it is speck that the identification module, which identifies the abnormal hot spot, the layer
Preset shadow is superimposed to the position that the speck is corresponded in described image by folded module；
When it is blackening that the identification module, which identifies the abnormal hot spot, preset bright shadow is superimposed to described by the layered module
The position of the blackening is corresponded on image；
The projecting apparatus, image acquisition device, the identification module, and the layered module are electrically connected with the main control module
Connect.
