Description
Technical field
The present invention relates to the automatic identification technology field, electric marking system and the method for reading and making comments the result handled in particularly a kind of automatic identification.
Background technology
The system and method for existing electric marking system adopts scanner as main paper picture sampling instrument, after examinee's test paper and before the teacher reads and makes comments, the paper batch scanning of also not read and made comments is handled and stored in the computer system and go, allow the teacher come the picture of paper is read and made comments with the mode of mouse and keyboard input then, comprise mark mark, some symbol of punctuating, additional comment etc. by computer interface.Though this electric marking system has can instant recording and the function of statistics mark, but because mark separates with original paper, teacher's the vestige of reading and making comments can not be remained on the original paper, can not allow the student in time obtain reading and making comments the result easily, thereby limit the effective application of electric marking in teaching.
Existing other electric marking systems require just to make a special masterplate file, and print special answer sheet before the work of going over examination papers does not begin, and could allow these systems paper to be carried out works of treatment such as batch scanning, location and identification.
Existing other electric marking system has the requirement of strictness in order to scan in enormous quantities paper fast to the quality of paper.The above laser stamping paper of general 70 grams could guarantee the reliability of scanning process.Low-quality paper for example 40 restrains 50 paper that restrain, and often causes faults such as holding paper.The examination flow process adopts traditional electric marking system, often brings the cost problem for the examination unit.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of automatic identification to handle electric marking system and the method for reading and making comments the result.
Native system is by adopting picture pick-up device and the computer that hangs, allow the personnel of reading and making comments on original paper, to carry out batch volume operation of traditional approach, keeping when whole hand-written on the paper read and make comments label symbol, in real time paper is taken pictures, and use multiple technologies captured hand-written symbol is carried out Dynamic Recognition, thereby obtain for example as critical datas such as student's student number, single track topic mark and whole volume marks.System and method among the present invention, guaranteed that the personnel that go over examination papers both can change the original convenience of reading and making comments working method intuitively fully on paper, keep and to read and make comments vestige so that the examinee can see and keep reliably and read and make comments the result, the function that makes full use of simultaneously the electronics computer is again carried out the processing of electronics file, Symbol recognition, the corresponding examinee's identity of paper, is calculated mark and carry out multi-level statistics and analysis automatically, for the work of going over examination papers has improved efficient and operability the paper after reading and making comments.
The electric marking system of reading and making comments the result is handled in a kind of automatic identification, comprise: CPU (central processing unit), image capture device, the control signal input equipment, show output device, storage unit, CPU (central processing unit) connect image capture device, control signal input equipment, show output device that CPU (central processing unit) is connected with storage unit is two-way.
The electric marking method of reading and making comments the result is handled in a kind of automatic identification, comprises the method for reading and making comments of electric marking and the optional method of reading and making comments of electric marking.
Automatic identification of the present invention is handled the electric marking method of reading and making comments the result and has been used following algorithm.
1. the algorithm of Handwritten Digit Recognition (Fig. 8)
2. the algorithm (Fig. 9) of hand-written six point codings identification
By fixing of six summits, with artificial hand-written arabic numeral relative standardization.For improving the discrimination of digitizing identification, a kind of method of practicality has been proposed.Can according to reality write the figure place requirement, realize the mark sign of numeral.
Specifically referring to Fig. 5
3. the mark recognizer of variant color (with the algorithm of red pen mark) (Figure 10)
Algorithm flow (Figure 11)
The result calculates and statistical study mechanism (Figure 12)
Beneficial effect
System and method among the present invention, adopted the suspension type video camera to form first and read and made comments worktable as computer peripheral equipment, allow the teacher can enough traditional paper the pen or shape tools, mode according to nature is is directly read and made comments on original paper, avoided separating of paper and mark, in the process of reading and making comments, grasp the picture as a result after reading and making comments simultaneously at any time, under the cooperation of computer, the label symbol of reading and making comments generation is carried out real-time or non real-time automatic identification, and behind examinee's number and examinee's identity formation one-to-one relationship, carry out the record of automatic score with identification, calculate, processing such as statistics and analysis.Compare with existing other electric marking system, have and to guarantee to read and make comments vestige and be retained in actual demand on the original paper, make full use of the real-time statistic analysis of computer and the superior functions such as electronics archive management of picture again; Both improved and read and made comments efficient, kept paper and the integraty of reading and making comments vestige again, and allowed the examinee can access best feedback result, and allowed electric marking can adapt to the actual demand of work about test better.
System and method among the present invention, do not require that the teacher makes special masterplate in advance, the examinee indicates candidate ID as long as import hand-written numeric character in the approximate region of appointment, the teacher is as long as the score that hand-written mark per pass is inscribed in the approximate region of appointment, system just can generate a complementary masterplate automatically and automatically identify the examinee and the one-to-one relationship of paper and read and make comments result data, carries out statistical study then automatically.Operating process has been simplified in this innovation in a large number, has improved system's availability in practice.
System and method of the present invention because the form that has adopted suspension type to take pictures, can be handled any different quality, different size specification even the paper of raising row more, is that the examination unit saves great amount of cost, and the dirigibility of operation is provided.
