Description
Technical field
The present invention relates to a kind of scanning device and scan method, especially a kind of industrial scanning device of platform mobile model wide cut
And scan method, belong to broad width scanning technical field.
Background technology
Obtain patterns of high precision scanner, according to the modes of emplacement on scanned surface, can be generally divided into contact and
It is contactless.On contact type scanning instrument, scanned surface is to directly overlay supporting surface, such as general family expenses are swept with office
Instrument is retouched, manuscript is directly to cover to be pressed on transparent glass surface；Contact type scanning instrument applies in general to manuscript drawing and soft thing (for example
Fabric) scanning, but the general breadth that can be scanned is smaller.On non-contact scanning instrument, scanned surface is not contacted directly
The scanning of on-line checking is usually non-contact scanning on any supporting surface, such as production line, then such as scanner of swepting slip code,
It is also noncontact scanning in principle.
Distinguished according in scanning process, being scanned object in mobile or scanning element mobile, can be divided into and sweep
Retouch element movable type and platform mobile.General family expenses and the scanner of office are that scanning element is portable, scanned
Body is covered in after glass support plate, and image is obtained by the movement of scanning element.The scanning of on-line checking is general on production line
It is platform mobile, scanning element is arranged on fixed position.
At home, existing scanner product, generally existing problems with：
1) it can only scan vertically downward.Scanning angle, similar to photo angle.When scanning of a surface has concavo-convex object
Wait, different scanning angle, vision and image effect out is different.Existing home products only has single angle vertically downward
Degree scanning.
2) without scanning preview function, or scanning preview take it is long.Domestic like product does not scan preview work(
Can, also without the function that scanning area is flexibly chosen after preview；And the scanning preview of imported product take it is long because wide cut
Reason, preview length × a width of 1500 × 1000mm breadth was taken close to 2 minutes.
3) soft object, when being placed on platform, often there are the feelings that can not be paved in such as wide cut drawing and flimsy material
Condition, directly affects quality of scanning.
4) without automatic focusing.
5) lack and effectively reduce the setting that veiling glare enters camera lens.
6) temperature control without houselights.Light on same category of device, has two kinds, a kind of is the cold light of alternating current
Lamp, one kind is direct current LED.The shortcoming of alternating current cold light lamp is electric frequency far smaller than scan frequency, due to power supply week
Brightness slight change in phase and cause picture quality unstable.In order to obtain steady illumination, direct-current LED lamp is more preferable selection；
But direct-current LED lamp has the problem of generating heat big, if not controlling radiating, the colour temperature of light can be influenceed, so as to influence pattern colour
It is color.

The scanning in second piece of region, and so on carry out the 3rd piece even the 4th piece of region scanning.
S7, control software are obtained after whole scan images, if more than one image, control software can be automatic on backstage
Operation image splice program, then exports the complete image for the scanning area entirely selected by frame.
S8, the end of scan, platform 3 automatically return to origin position.
S9, control software is exited, scanning device automatically returns to origin position：Platform 3 is located at the limit position on the left side, lamp bracket 6
Underlying limit position, light support arm 7 is located at the centre of lamp bracket 6, and the height of cantilever 4 is located at resolution ratio 600dpi position
Put, line-scan digital camera 5 is vertical downwardly directed to the center line of platform 3.
Embodiment 2：
As shown in Figure 10, the present embodiment is mainly characterized by：The scanning device also includes area array cameras 30, the face battle array
Camera 30 is arranged on the top of column 2, and is connected with control device, and the camera lens of area array cameras 30 is towards platform 3, and area array cameras 30
Camera lens field range cover the field range that scope shown in dotted line in whole platform 3, figure is camera lens；The area array cameras 30 is
The other colored area array cameras with flash lamp of one mega pixel level, it is contemplated that preview graph is not high to resolution requirement, with can
The size shape for comparing object on accurate discrimination platform is standard, and mega pixel class disclosure satisfy that requirements, area array cameras 30 and
Position and angle between the platform 3 of initial position (origin position that i.e. above-described embodiment 1 is mentioned) are fixed, area array cameras
30 are controlled by the control software of computer, it is necessary to during preview, the preview button in selection control software, 30 pairs of area array cameras
Platform 3 shoots a pictures and is output to control software, and control software is then automatic to carry out distortion correction to picture, then high-ranking officers
Preview image after just is shown on control software interface, and specific scanning area is chosen for user, if using line-scan digital camera,
Due to the image-forming principle of line-scan digital camera, user's previewing scan effect must first carry out a prescan, and the time of cost is more, and
The image-forming principle of area array cameras is different from line-scan digital camera, and scanning preview speed can be effectively improved by shooting progress preview using area array cameras
Degree, although pixel value is not high, but be enough to allow the quick frame choosing of user to need the region scanned, operation ease is significantly improved.
The scanning device course of work of the present embodiment in place of the difference of embodiment 1 with being：Before step S 4, if with
Family does not need preview, directly can need the region scanned in the platform frame upper ledge choosing of simulation, it is determined that after, line-scan digital camera 5 is along outstanding
Arm 4 is automatically adjusted to the position needed；If user needs preview, preview function, the area array cameras positioned at the top of column 2 are selected
The image of 30 one platform 3 of automatic shooting, control software obtains after the picture that area array cameras 30 is shot, line distortion is entered automatically and is entangled
Just, and it is shown in control software interface, picture upper ledge choosing of the user after correction needs the region scanned, it is determined that after, linear array phase
The position that machine 5 is automatically adjusted to need along cantilever 4.
In summary, it is to be directed to some particular industry applications the invention belongs to non-contact platform mobility scanning device
The special equipment of scene, its effect is can flexibly to obtain the high accuracy and height of the scanned wide cut body surface under different visual angles
The picture on surface of color rendition degree, the native texture such as scanning stone material, timber, applied to ceramic tile/grain board/wallpaper industry
Pattern is developed, and this is that contact and general breadth scanner are not accomplished；For example scan wide cut manuscript or should not directly contact
Object (contact may damage scanned object), be adapted to Wen Bo/archives/artistic management lossless original copy scanning；Example
Such as plate making industry, the high-precision scanning demand of the different materials of different clients can be tackled.
It is described above, it is only patent preferred embodiment of the present invention, but the protection domain of patent of the present invention is not limited to
This, any one skilled in the art is in the scope disclosed in patent of the present invention, according to the skill of patent of the present invention
Art scheme and its inventive concept are subject to equivalent substitution or change, belong to the protection domain of patent of the present invention.
