Step S102：Standard identification point in the normal place topological diagram is traveled through, and based on the mark for traversing
The coordinate of quasi- identification point, searches the identification matched with the standard identification point position for traversing in answer card graphic to be identified
Point.As shown in figure 3, step S102 specifically may include following steps：
Step S102-1：Standard identification point in the normal place topological diagram traveled through, and based on traversing
The coordinate of standard identification point, between the length and width and two neighboring standard identification point of the calculating standard identification point
Spacing.Wherein it is possible to the standard identification point in normal place topological diagram is traveled through according to default traversal rule, such as with every
Row or each column are unit, and the traversal of the row of a line a row or column one or is traveled through etc. with S type traversal orders.
Step S102-2：Between length and width and two neighboring standard identification point based on the standard identification point
Spacing, search the identification point matched with the standard identification point position for traversing in answer card graphic to be identified.
Step S103：If finding the identification point of the location matches, the identification point is positioned.If finding position
The identification point matched somebody with somebody, then the coordinate of the standard identification point be the coordinate of the identification point matched with the standard identification point, it is accurate fixed
Position success.After step s 103, can also carry out step S104.
Step S104：It is all with what the standard identification point position matched in calculating the answer card graphic to be identified
The number of identification point, and calculate the percentage that the number accounts for the normal place topological diagram Plays identification point total number.
Percentage according to being obtained in step S104 is judged, based on the result for judging, or performs step S105-1, or
Step S105-2 is performed, or performs step S105-3.If the percentage performs step in the default completion parameter area
Rapid S105-2；If the percentage is less than the minimum value in the default completion parameter area, step S105-1 is performed；If institute
State percentage and then perform step S105-3 more than the maximum in the default completion parameter area.In the present embodiment, preset
Completion parameter area is set to 50%<=X<=95%, X represent percentage.Wherein, the setting of 95% grade these parameters is root
The optimal value for drawing factually is tested, typically by parameter setting in this size, 99% answering card can have been avoided to misidentify problem,
If when the effect of answering card printing in itself or duplicating were too poor, the above-mentioned default completion parameter model of adjustment that could be appropriate
Enclose.
Step S105-2：If the percentage is opened up in the default completion parameter area based on the normal place
The non-matched position of identification point flutterred in answer card graphic to be identified described in the coordinate pair of figure Plays identification point carries out completion, with

And the spacing between two neighboring standard identification point, the identification point deletion sites in the answer card graphic to be identified are carried out
Completion.Further, after step S105-2, step S106 is performed.In the present embodiment, when 50%<=X<When=95%,
Then determine to need the operation for performing step S105-2, it is necessary to carry out completion.
Step S105-1：If the percentage is less than the minimum value in the default completion parameter area, it is determined that described
Answer card graphic to be identified be image not up to standard, it is impossible to the identification point is accurately positioned, and send report an error warning or carry
Show operation.Prompt messages such as " image are not up to standard " can be sent, so that user is after receiving to remind, to the answer to be detected
Card carries out the operation such as manual identified or treatment, further avoid the misrecognition problem to answering card to be detected.In the present embodiment
In, when percentage is less than 50%, it is determined that the answer card graphic to be identified is image not up to standard.
Step S105-3：If the percentage is more than the maximum in the default completion parameter area, it is determined that described
Answer card graphic to be identified is image up to standard.I.e.：The position of the identification point matched with standard coordinate for obtaining is to be identified answering
The exact position of the identification point of card is inscribed, positioning terminates.
Step S106：The identification point number for calculating the answer card graphic to be identified after the completion accounts for the normal place and opens up
Flutter the percentage of figure Plays identification point total number.Calculating process and computational methods are referred in above-mentioned steps S101 to S104
Hold.After step S106, the percentage after completion is judged, based on the result for judging, or perform step S107-1, or hold
Row step S107-2.If the percentage performs step more than or equal to the maximum in the default completion parameter area
S107-1；If the percentage is less than the maximum in the default completion parameter area, step S107-2 is performed.
Step S107-1：If the percentage is more than or equal to the maximum in the default completion parameter area, really
Answer card graphic to be identified after the fixed completion is image up to standard；I.e.：The position of the identification point matched with standard coordinate for obtaining
The exact position of the identification point as answering card to be identified is put, positioning terminates.
Step S107-2：If the percentage is less than the maximum in the default completion parameter area, it is determined that described
Answer card graphic to be identified after completion is image not up to standard, it is impossible to which the identification point is accurately positioned, and sends and report an error
Warning or prompting operation.The prompt message such as " image is not up to standard " or " completion failure " can be sent, so that user is receiving
After prompting, the operation such as manual identified or treatment is carried out to the answering card to be detected, further avoid to answering card to be detected
Misrecognition problem.
It should be noted that step S105-2 and its afterwards the step of, carried out primarily directed to answering card as shown in Figure 6
Treatment, answering card as shown in Figure 6, due to print problem and cause the color of the rectangle frame of answering card too light, that is, recognize
The color of point is too light, so as to cause cannot to search or match the problem of the too light identification point of color.For this problem, just need
Completion operation is carried out to that cannot search or match the too light identification point of color.
