Abstract
The utility model relates to a seal recognizing and inputting device with single-channel reflection of a top-opening type, which is composed of a suit of image shooting system, a work surface illuminating lamp, a reflecting mirror and a box body, wherein the reflecting mirror is arranged in the box body, the surface of the reflecting mirror forms an angle of 45 DEG with the axial line of a camera and the inner wall of the box body, and a work surface is arranged on the top and is provided with an object carrying lens as an inputting window. The utility model only uses the image shooting system to complete the recognition and the input of seals, has the advantages of no light loss, clear imaging and convenient and rapid recognition method. The box body is additionally provided with a reflecting lens which forms an angle of 45 DEG with the axial line of the camera, and the imaging is transversely collected. Thus, the utility model can obviously lower the height of the recognizing and inputting device, have easy operation and use, further reduce optical diffusion, and ensure that shot images are complete and clear.
Description
The utility model is the part of security stamp identifier, relates in particular to a kind of top fenestration single channel refraction seal recognition input device.
Present security stamp identifier normally accesses the seal that is reserved in the computer picture database, compares with certain algorithm with the seal to be measured of input is visual, provides the differentiation result then.One class security stamp identifier is arranged now, adopt twin-lens, it is the collection that binary channels is carried out the seal image, specific implementation has dual mode: (one) will measure the seal window and be placed on the worktable bottom, two video cameras of parallel placement keep at a certain distance away on same level height, at first seal is placed on the platform of first video camera below during use, picked-up seal picture absorbs topography to seal then below shifting another video camera on the slide rail onto.(2) two video camera square crossings are placed, workplace can be located at the top, and places a semi-transparent semi-reflecting eyeglass in light path, can divide two light paths to gather the whole and topography of seal simultaneously.
More than these two kinds of binary channels seal image recognition input devices, being specially adapted to also needs the situation that the local superfine anti-instrument striped of seal is discerned except that to the identification of whole seal.Daily life makes still common seal with the most use, does not promptly have local false proof striped.If but this binary channels pattern recognition input media is used for the identification of common seal, then causes the wasting of resources, has increased cost, the simultaneous faults rate increases relatively, has reduced reliability.
The purpose of this utility model is exactly in order to address the above problem, and a kind of top fenestration single channel refraction seal recognition input device is provided, and this device is highly suitable for the identification to common seal.
Top fenestration single channel refraction seal recognition input device, form by a cover camera system, face lighting lamp, catoptron, casing, it is characterized in that: in casing, be placed with catoptron, mirror surface and camera axis and cabinet wall angle at 45, workplace is located at the top, the loading eyeglass is arranged as input window on the workplace.
Because the utility model has only a passage, promptly only can finish the identification of seal is imported with a cover camera system, there is not the loss of light, imaging is more clear, and recognition methods is also easy, quick; Simultaneously also reduced cost, increased reliability, reduced failure rate, the volume of this device can be done smaller and more exquisitely, is convenient to move.
Owing in casing, be added with a reflex reflector lens with camera axis angle at 45, be laterally to gather imaging, therefore can significantly reduce the height of recognition input device, easy operating and use more, further reduce optical diffuser, guarantee that the image of picked-up is complete more clear.
Fig. 1 is an one-piece construction perspective diagram of the present utility model.
Describe in detail below in conjunction with accompanying drawing.
As shown in the figure, the 1st, video camera, the 2nd, workplace, the 3rd, loading eyeglass, the 4th, illuminating lamp tube, the 5th, casing, the 6th, rectangular window, the 7th, catoptron, the 8th, scalable slide bar.
Top fenestration single channel refraction seal recognition input device, form by a cover camera system, face lighting lamp, catoptron, casing, in casing, be placed with catoptron, mirror surface and camera axis and cabinet wall angle at 45, workplace is located at the top, the loading eyeglass is arranged as input window on the workplace.
Camera system is made up of video camera and camera lens, but video camera is installed on the slide bar of regulating all around, so that video camera is adjusted in the optimum position.Tested seal is placed on the loading eyeglass 3, illuminated lamp 4 illuminations of seal image, and 1 reflex picked-up seal image through catoptron 6 of video camera is finished the work of gathering image.Video camera is target surface 1/3 an inch CCD video camera, 410TV line, 0.05LEX illumination; Camera lens, 1/3 inch, focal length 25MM, iris ring, loading eyeglass, the thick optical glass of 5MM.
The angle of catoptron and cabinet wall can by adjusting the axis direction of video camera, still can be finished image acquisition work between 30 °～60 °.
Claims (2)
1, top fenestration single channel refraction seal recognition input device, form by a cover camera system, face lighting lamp, catoptron, casing, it is characterized in that: in casing, place catoptron, mirror surface and camera axis and cabinet wall angle at 45, workplace is located at the top, the loading eyeglass is arranged as input window on the workplace.
2, seal recognition input device as claimed in claim 1 is characterized in that: but camera system is installed on the slide bar of regulating all around.
