Abstract

The utility model discloses a machine-readable answering card with titles and options, and is characterized in that: the options are optical mark boxes, each optical mark box is a central symmetry figure, the middle part of the optical mark box is blank, the frame of the optical mark box is black or colorful, the area ratio of the black or colorful frame and the blank part is more than 1:5; the answering card has low requirement on card, also has no special requirement on stationery and paper, has lower requirement on card reading equipment, is very convenient in writing and use, has extensive application range, lower production cost, lower use cost and ensures the accuracy rate to approximate 100%.

Description

Machine-readable fulfilling card

Technical field

The utility model relates to the statistics field, particularly a kind of machine-readable fulfilling card that can quick identification.

Background technology

Accuracy, the integrality of data generally all is particular about in the statistics field.

But in the statistic processes of survey, generaI investigation activity, various test questionnaires, after traditional investigation method all adopted questionnaire to fill in, by manually adding up one by one, this sample loading mode was not only added up the cost height at present, and accuracy also can not get guaranteeing, and speed is very slow.

The machine-read card that applies to for a lot of examinations, must guarantee that the card face is neatly clean, spot or folding line etc. can not be arranged, there is very strict requirement the hardware device aspect that reads card, and its very flexible, the speed that reads is also slower, with respect to the mode of complicate statistics, just improved the accuracy of its data, but because its requirement to hardware, paper, and, limited the usable range of this machine-read card to the specific (special) requirements of the full-filling tool that uses.

At the statistical of above two kinds of traditional fulfilling cards or questionnaire, all be various obvious defects, therefore need a kind of fulfilling card of machine readable more easily.

The utility model content

The purpose of this utility model is to provide a kind of machine-readable fulfilling card of full-filling fast very easily, not only can be very low to the requirement of card itself, and reading card equipment also require lower, very convenient use, and suitable application area is more wide.

The technical solution of the utility model is as follows:

Machine-readable fulfilling card, be provided with title and option, it is characterized in that: described option adopts the optical markings frame, described optical markings frame is a centrosymmetric image, in the middle of the optical markings frame is white blank parts, the edge of optical markings frame is black or colour, and the area ratio of described black or colored and white was greater than 1: 5.

The edge of described optical markings frame is a black, and is triangle, quadrilateral or circle etc.

The centre of described white blank parts also is provided with the central point mark, and the central point mark can be black, perhaps other colours.

In the time of this fulfilling card of full-filling, must streak white box, slide into the opposite side of optical markings frame then, promptly this card of full-filling the time, must use pen to destroy the recognition feature of original optical markings frame, otherwise be considered as invalid full-filling from a side on optical markings circle limit.

Behind good this fulfilling card of full-filling, pass through scanner scanning, read in fulfilling card image after the scanning by the recognition software system on the computing machine then, then image is carried out pre-service such as picture binaryzation, denoising point, scanning inclination error correction, judge user's full-filling content again by the extraction of optical markings frame then, store the recognition effect of fulfilling card at last, print the content of being convenient to add up full-filling.

The beneficial effects of the utility model are as follows:

This fulfilling card is very low to the requirement of card itself, and full-filling tool, paper are not all had specific (special) requirements, and the requirement of reading card equipment is also lower, very conveniently fill in and use, suitable application area is more wide, and production cost is lower, use cost is also lower, and accuracy rate is near 100%.

Embodiment

Shown in Fig. 1-6, machine-readable fulfilling card, be provided with title and option, described option adopts the optical markings frame, described optical markings frame is a centrosymmetric image, in the middle of the optical markings frame is white blank parts 2, and the edge 1 of optical markings frame is black or colour, and the area ratio of described black or colored and white was greater than 1: 5.

The edge 1 of described optical markings frame is a black, and is triangle, quadrilateral or circle.

In the middle of the described white blank parts 2 central point mark 3 is set also, central point mark 3 can be black, perhaps other colours.

In the time of this fulfilling card of full-filling, must streak white box, slide into the opposite side of optical markings frame then from a side on optical markings circle limit, shown in Fig. 8-13, when being this card of full-filling, must using pen to destroy the recognition feature of original optical markings frame, otherwise be considered as invalid full-filling.

As shown in Figure 7, behind good this fulfilling card of full-filling, pass through scanner scanning, read in fulfilling card image after the scanning by the recognition software system on the computing machine then, then image is carried out pre-service such as picture binaryzation, denoising point, scanning inclination error correction, judge user's full-filling content again by the extraction of optical markings frame then, store the recognition effect of fulfilling card at last, print the content of being convenient to add up full-filling.

The method of " optical markings extraction " is illustrated in figure 1 as example:

The monochrome pixels ratio that reads along the direction of arrow when software systems satisfies black: white: black=1: in the time of 1: 1, then think and found an optical markings.Simultaneously, system's existence that also can come the auxiliary judgment optical markings according to means such as black and white region area size, region geometry shapes.

When the user has carried out full-filling, then this mark no longer can be found.Card after the full-filling and blank card are compared, find out the content of user institute full-filling.
