Abstract
The invention discloses an image smear point aggregation coding recognition card, and the card comprises a synchronous head, a primary positioning block, a secondary positioning block, and a grading frame. The lateral direction of the grading frame is aligned with the primary positioning block, and the longitudinal direction of the grading frame is aligned with the secondary positioning block. The grading frame is provided with (N+1) grading regions which are distributed in the longitudinal direction, and the serial numbers of the grading regions is sequentially arranged to be 0, 1,..., N, wherein N is a natural number. The secondary positioning block is firstly recognized in a recognition process, and all recognition regions are automatically calculated according to the position of the secondary positioning block. A score smeared by a user is finally obtained through the comparison of a gray value and a threshold value. The recognition card is smaller in actual occupied space, is more flexible in swinging, and overcomes the deformation at a position far from an original point to the maximum degree because the secondary positioning technology is used. From the aspect of actual application results, the recognition card is high in recognition rate, is more convenient for scoring and filling, and has no remarkable side effect.

Summary of the invention
The object of the present invention is to provide a kind of real estate less, put more flexible, and the image painting point polymerization code identification card that discrimination is high, the subjectivity that the method is mainly used in papery examination paper divides collection.
For achieving the above object, the invention provides following technical scheme:
A kind of image is coated with some polymerization code identification card, and comprise synchronous head, one-time positioning block, secondary locating piece and scoring frame, the horizontal direction of described scoring frame aligns with one-time positioning block, and longitudinal direction aligns with secondary locating piece; Described scoring frame is provided with longitudinally uniform (N+1) individual scoring region, and scoring region is followed successively by numerical value 0-N from top to bottom, and wherein N is natural number; In the process identified, first secondary locating piece is identified, more automatically calculate all identified regions according to the position of secondary locating piece, then compared the score value finally showing that user is coated with by gray scale and threshold value.
As the further scheme of the present invention: at numerical value be N scoring region immediately below increase decimal place scoring region; If this position is true, then last score value is that former score adds 0.5 point; If this position is false, then last score value is former score.
As the further scheme of the present invention: adopt biserial to be coated with point, namely set up a row scoring region on the right side of scoring frame, distinguish the individual position of score value and ten by the scoring region arranging the different sizes of two row.
As the further scheme of the present invention: described scoring region and one-time positioning block and secondary locating piece are wide contour rectangular block, and the spacing between adjacent scoring region and between adjacent one-time positioning block is the half of scoring region height.
Compared with prior art, the invention has the beneficial effects as follows: the real estate that this image is coated with some polymerization code identification card is less, put more flexible, and owing to employing secondary positioning technique, the distortion away from origin position is overcome to greatest extent.From practical using result, discrimination of the present invention is high, gives point full-filling more convenient, does not also have obvious spinoff.
