Abstract
The utility model relates to a photography scanner, which comprises a camera lens, a charge coupled device, a DSP chip and a USB interface, wherein the camera is connected with the charge coupled device, the DSP chip and a coder in sequence; and the USB interface is connected with the DSP chip. The utility model has the benefits that firstly, the precision is high, and the slide errors do not occur; since the camera lens is adopted to shoot a scanned document, the high-precision and high-efficiency automatic correction of photo distortion is performed to shoot original images, the high-precision large-format image scanning is achieved, and particularly, the precious and old documents can not be damaged; secondly, the shooting speed is faster than traveling scan speed; and thirdly, the useis convenient. In short, along with more and more application of scanners in routine office work, characteristics of the photography static scanner are advantages for development of the photography scanner.
Description
Technical field
The utility model relates to a kind of scanner, particularly a kind of tomography scan instrument.
Background technology
Modern handle official bussiness be can't do without the application scanning instrument, traditional scanner has two kinds: a kind of is the imageing sensor mobile scanning, a kind of is that imageing sensor is motionless, the scanner that scanned document rolls, the sort of form no matter, imageing sensor and scanned document have micro displacement in scanning process, cause not fogging clear and distortion, influence scanning effect.Because relatively moving of drawing and transducer, guarantee the precision of scanning patter, the arrangement of the processing of the transmission device of conventional scanner (comprising stepping motor, belt, pulley, gear, guide rail etc.) and installation, transducer will be very exquisite, scanner speed is fast more, scanning patter is big more, precision prescribed is just high more, so the cost and price of conventional scanner (large format scanner and rapid file graphics scanner) is very high; Because the plain scan instrument all has in order to adjust the mobile device of transducer and drawing relative position, long-term use will produce wearing and tearing, and mobile device is very big to the scanning accuracy influence, so the wearing and tearing of mobile device are with the image scan precision---and the precision of conventional scanner can reduce along with long-term use; The easy holding paper of drum scanning appearance, especially to shabby drawing, the fragile drawing of drum scanning instrument.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of tomography scan instrument.Adopt the imageing sensor (matrix form charge coupled device ccd) of two-dimensional arrangements to carry out graph scanning, rectangle plane zone of the Polaroid scanning of matrix form element CCD (moment takes pictures).By the arrangement and fixing that specifies Spacing, m * n two-dimensional image sensor receives instruction each self-scanning of back and finishes whole graph scanning in the corresponding region separately with m * n two-dimensional image sensor.In scanning process, drawing and two-dimensional image sensor maintain static, and do not relatively move, so the photographic imagery scanner belongs to the static scanning instrument.Because the deviation of camera position, the deviation of camera optics element and drawing diverse location are different with distance of camera lens, every width of cloth original photo all has certain deformation, but the image of photographic imagery scanner full-automatic high precision correction of photograph deformation and the different photos of automatic splicing.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of tomography scan instrument, it is characterized in that: comprise camera lens, charge-coupled device, dsp chip, encoder, USB interface, described camera lens is connected with charge-coupled device, dsp chip, encoder successively, and described USB interface is connected with dsp chip.
The beneficial effects of the utility model are: 1, precision height does not have displacement error.Owing to adopt camera lens to take scanned document, the original image of taking is carried out high accuracy, high efficiency automatic correction picture distortion has realized high accuracy large format graph scanning, especially the old file for preciousness can not cause damage; 2, speed is fast, and it is faster than motion scan to take pictures.3, easy to use.More and more used along with scanning in routine office work in a word, the characteristics of photographic static scanner will be its advantages for development.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram and as Figure of abstract.
Embodiment
As shown in Figure 1, the tomography scan instrument comprises camera lens, charge-coupled device, dsp chip, encoder, USB interface, and camera lens is connected with charge-coupled device, dsp chip, encoder successively, and USB interface is connected with dsp chip.，
Use video camera to take scanned object, generate original image light signals, become the signal of telecommunication through charge-coupled device (CCD), dsp chip carries out digital processing in video camera, revise the deviation owing to camera position, the deviation and of the different distortion that cause of drawing diverse location of camera optics element with distance of camera lens, image is carried out DIS (numeral is anti-shake) to be handled, exposure compensating, make image more clear, convert the signal of telecommunication (analog signal) to digital signal and send encoder to, after USB interface sends to PC reading scan image.
Claims (1)
1, a kind of tomography scan instrument is characterized in that: comprise camera lens, charge-coupled device, dsp chip, encoder, USB interface, described camera lens is connected with charge-coupled device, dsp chip, encoder successively, and described USB interface is connected with dsp chip.
