Description
Technical field
The invention belongs to field of Educational Technology, is related to a kind of answer recognition methods, and in particular to a kind of real-time synchronization and height
Imitate the answer recognition methods of identification.
Background technology
When taking an exam or investigating to student, it usually needs student carries out answer and answer result is identified.
In traditional paper pen pattern answer, first answer is all used mostly, it is rear that answer knowledge is entered otherwise using scanning technique.But
It is low that efficiency comparison otherwise is known in this answer.As science and technology enters education sector, efficient answer identification technology will turn into religion
Educate the important ring in evolution.
Specifically, from the point of view of answer identification, answer identification is from initial manual identified and has developed into the machine later stage and sweeps
Retouch identification.As examination number increases, manual identified is already insufficient for the efficient of epoch now.And the machine later stage identifies
Although improving part efficiency, also there are many limitations, it is necessary to carry out answer with different pens, the later stage is also required to artificial right
Answering card carries out the processing such as migrating.With the development in epoch, a kind of our more efficient answer identifications of needs all the more and more save
The about method of human resources improves our production efficiency.
In view of the drawbacks described above of prior art, there is an urgent need to develop a kind of new answer recognition methods.
The content of the invention
It is contemplated that overcome the above-mentioned problems in the prior art, there is provided a kind of real-time synchronization and efficient identification are answered
Recognition methods is inscribed, it can carry out answer identification while answer, and can effectively be identified in specific region.
To achieve these goals, the present invention provides following technical scheme：
The answer recognition methods of a kind of real-time synchronization and efficient identification, it is characterised in that comprise the following steps：
(1) the answer data on electric answer card, are sent to server end in real time；
(2), the server end analyzes and processes to the answer data, judges whether answer person's handwriting is effective, if nothing
Effect then judges that answer is invalid, enters step (3) if effectively；
(3), judge that answer person's handwriting whether in effective coverage, judges that answer is invalid if not in effective coverage, if
Then enter step (4) in effective coverage；
(4), judge the length of answer person's handwriting whether in prescribed limit, judge if not in prescribed limit answer without
Effect, enters step (5) if in prescribed limit；
(5) slope of answer person's handwriting, is calculated；
(6), judge that the slope whether in prescribed limit, judges that answer is invalid if not in prescribed limit, if
Then judge that answer is correct in prescribed limit.
Wherein, the answer recognition methods of the real-time synchronization and efficient identification further comprises:
(7), the answer recognition result of every problem is pushed to display platform and by display platform to answer by the service end
As a result shown.
Further, wherein, in the step (7), the service end pushes to the answer recognition result of every problem more
Individual display platform is simultaneously shown to answer result respectively by the multiple display platform.
In addition, the answer recognition methods of the real-time synchronization and efficient identification further comprises：
(8), playback system reads the answer data in the server end and answer process is played back.
Compared with existing answer recognition methods, the answer recognition methods of real-time synchronization of the invention and efficient identification has
Following advantageous effects：
1st, it can carry out Real time identification to specific region.
2nd, its match cognization degree is high, suitable for various classroom environments, tests up to ten thousand times, reliability is high.
3rd, it can realize that multi-platform real-time synchronization shows answer data.
4th, it can be played back to answer process.
Brief description of the drawings
Fig. 1 is the real-time synchronization of the present invention and the flow chart of the answer recognition methods of efficient identification.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples, and the content of embodiment is not as the guarantor to the present invention
Protect the limitation of scope.
Fig. 1 shows the flow chart of the real-time synchronization and the answer recognition methods of efficient identification of the present invention.As shown in figure 1,
The real-time synchronization of the present invention and answer recognition methods of efficient identification comprises the following steps：
First, student carries out answer on electric answer card, and the electric answer card can be real-time by answer data thereon
It is sent to server end.
In the present invention, it is preferred to the electric answer card wirelessly answer data are sent in real time it is described
Server end.
Secondly, the server end analyzes and processes after the answer data are received to the answer data,
To judge whether answer is correct.
In the present invention, when judging whether answer is correct, mainly including the following steps：
1st, judge whether answer person's handwriting is effective, judge that answer is invalid if invalid, enter in next step if effectively.
2nd, judge answer person's handwriting whether in effective coverage in the case of answer person's handwriting is effective.If not in effective coverage
Then judge that answer is invalid, enters in next step if in effective coverage.
3rd, in the case where answer person's handwriting is in effective coverage, the length of answer person's handwriting is judged whether in prescribed limit,
Judge that answer is invalid if not in prescribed limit, enter in next step if in prescribed limit.
4th, the slope of answer person's handwriting is calculated.The computational methods of the slope of answer person's handwriting belong to the known method of this area, no
It is the emphasis of the present invention, is not described in detail herein.
5th, in the case where calculating slope, the slope is judged whether in prescribed limit, if not in prescribed limit
Then judge that answer is invalid, judges that answer is correct if in prescribed limit.
So, whether the present invention judges to answer in answer area using region recognition algorithm to specific region, and uses
Person's handwriting recognizer answer and judges whether answer is effective to match.Therefore, recognition efficiency is higher.
After judging answer result, then, the service end can push away the answer recognition result of every problem
Deliver to display platform and answer result is shown by display platform.So, it is easy to understand answer result in time.
Certainly, in the present invention, it is preferred to, the answer recognition result of every problem is pushed to multiple displays by the service end
Platform, such as display platform 1 and display platform 2, and answer result is shown respectively by the multiple display platform.This
Sample so that answer result can be shown in many places, facilitate different people to understand answer result.
Finally, in the present invention it is possible to which answer data in the server end are read and to answer by playback system
Process is played back.So, it is easy to play back whole answer process, is easy to grasp and understands answer process.
The answer recognition methods of the present invention carries out answer identification with real-time synchronization, has both improved the efficiency of answer identification,
Also save the time of answering card migration.Meanwhile its recognition efficiency is high.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Embodiment restriction.For those of ordinary skill in the field, can also make on the basis of the above description
Other various forms of changes or variation.Here all embodiments can not be exhaustive.Every skill for belonging to the present invention
Row of the obvious changes or variations that art scheme is extended out still in protection scope of the present invention.
