Abstract
A high-speed photographing and scanning device using a mirror image for acquiring a paper document image comprises not only a high-resolution wide-angle camera but also added modules of glass, a mirror, lighting lamps and a shell, and the added modules and the camera form the integral device together.
Description
Technical field
The utility model relates to a kind of high-speed camera scanning means, more specifically relates to a kind of high-speed camera scanning means that utilizes mirror image to obtain the paper document image.
Background technology
For paper document is electronic, scanner is widely used.Traditional scanner is slow because relate to the speed of mechanical movement scanned document, and generally more than 10 seconds, busy office application occasion needs scanning device more at a high speed when obtaining the document 150dpi image of A5.The camera technical development so far, the high-resolution wide-angle camera be used at a high speed obtain the paper document image, less than the image that can obtain high definition in 1 second.
In the time of actual the use, the general user understands the fixing this special camera of oneself trying every possible means, and takes document.Also there is product that the special-purpose device that is conducive to regulate is provided, for example patent CN201514644U " a kind of device that generates electronic document for paper document ".
Its common defective is, camera and device are placed more random, and document is placed does not have clear and definite boundary, takes imaging easily crooked.The problem of especially severe is, document is exposed to open working environment, take the interference effect that the image quality quality is very easy to be subject to external environment illumination, such as reflective, light and shade is inhomogeneous, shade blocks etc., this becomes for example very big obstacle of OCR literal identification of office automation.
Summary of the invention
In order to reform existing high-speed camera scanning means, the utility model proposes a kind of high-speed camera scanning means that utilizes mirror image to obtain the paper document image, utilize closure and interior lighting so that the picture quality of obtaining is more stable, utilize camera to take the mirror mirror image of paper document so that the spatial volume of equipment is also greatly saved, outward appearance is more frivolous attractive in appearance.
The technical scheme that its technical problem that solves the utility model adopts is: referring to Fig. 1, increase glass 1, mirror 2, illuminating lamp 5 and shell 6 around camera 3.Glass and mirror are angled, placement paper document on glass, and imaging 4 in mirror, and camera 3 is taken perpendicular to mirror image 4.
There is a complete closure 6 the device outside, and whole device inside photographing only with the interior light illumination, is not subjected to extraneous illumination effect.
Interior light 5 is in vertical direction between glass and mirror, and is parallel with glass near glass, is positioned in the horizontal direction both sides.
The beneficial effects of the utility model are that device is outside a complete closure, only uses interior lighting, is not subjected to extraneous illumination effect.Ingeniously utilize glass to place document and mirror forms mirror image, take mirror image with camera again, than the direct shooting document of camera, saved half from camera to the document distance, thereby saved volume and the space hold of whole device, more aobvious brief frivolous attractive in appearance.
Description of drawings
Fig. 1 is the side generalized section of device;
Fig. 2 is glass and the illuminating lamp front view schematic diagram of device;
Fig. 3 is the mirror front view schematic diagram of device;
Wherein: 1 is glass; 2 is mirror; 3 is camera; 4 is the document mirror image; 5 is illuminating lamp, and 6 is shell.
Embodiment
Referring to Fig. 1, around camera 3, increase a closure 6, fixing glass 1 above the shell, below fixed mirror 2, both sides stationary lamp 5, back fixing camera 3.This does not describe in detail fixed form, and fixing glass and mirror can be used groove, and stationary lamp and camera can add screw with shell mechanism to be fixed.
The size of glass is of a size of reference with document, and for example destination document is the document of A5, and then glass size should be the A5 size.Camera, glass, the relative position angular relationship that the mirror three fixes is that the fixed angle of camera is perpendicular to being positioned over paper document on glass mirror image in mirror.
The difficult point that this new device implementation mainly needs to overcome is, glass and imperfect light penetrating object, and the surface of glass can have the mirror-reflection effect, that is to say, and glass just is equal to mirror.It is equal to the two sides mirror with mirror, can form repeatedly repeatedly imaging, comprises the imaging of document, the imaging of glass, and the imaging of mirror, the imaging of shell inboard, these imaging meetings repeatedly are superimposed repeatedly.Physical modeling and mathematical computations show, repeatedly imaging is inevitable repeatedly, can only weaken.The main method that weakens is to select the glass of clean transparent high transmission rate antiradar reflectivity, and regulates control glass, mirror and camera three's angle.For example, glass becomes miter angle with mirror, and the camera direction is parallel with glass.In fact photograph repeatedly imaging in order to reduce, glass and mirror angle are larger good, but consider the frivolous principle of device, and angle is the smaller the better.The overall principle of angular adjustment control is: 1, and device frivolous attractive in appearance; 2, photograph complete document mirror image; 3, photographed less to the greatest extent unnecessary imaging.Set up the threedimensional model design with area of computer aided, regulate on one side make up realistic model again, Yi Bian observe imaging, both combinations regulate making the imaging shooting effect reach perfect condition.At last, again mirror is done cutting, guarantee that photographing complete document mirror image gets final product, crop unnecessary imaging on every side, or to the otiose redundance of effective imaging.
Another difficult point of this new device implementation is, illuminating lamp is easily by glass and the imaging of mirror Multi reflection.Facts have proved, when illuminating lamp is fixed in shown in Fig. 1 Fig. 2 plants the position, be aided with the cutting of mirror, can avoid camera to photograph its imaging.Illuminating lamp is all improper in arbitrary other positions of the formed inside cavity of shell.
The inner surface of device should be painted complete white or complete black, should form diffuse reflection, should not form total reflection and inhomogeneous speck, because the inboard of shell in fact also is imaged in the image that camera photographs, to be superimposed upon on the mirror image of document, influential to picture quality.
In one embodiment, referring to Fig. 3, mirror 2 is cropped cut into trapezoidal.
