According to the coordinate information of each palace lattice, from the palace table images, the corresponding image of each palace lattice is extracted；
It is input to the corresponding image of each palace lattice in preset image recognition model, obtains the content information of each palace lattice.
Here, image recognition model is usually the supporting vector machine model that training is completed in advance, and the application not limits this
System；Content information can be number, additional character, the letter etc. in the lattice of palace.
In specific implementation, after the coordinate information for obtaining nine palace lattice, each palace lattice can be obtained from the table images of palace
The corresponding image of each palace lattice is input to and is previously-completed in trained supporting vector machine model, obtained each by corresponding image
The content information of palace lattice, for example, digital.
S105, if obtained current password sequence is not sky, and identical as previous keying sequence, then according to each palace lattice
Content information, the determining matched palace lattice of current password with the current password sequence, until having determined and current password
The palace lattice of each password match in sequence.
Here, the determining matched palace lattice of current password with the current password sequence, it is, determining current password
Whether the current password in sequence is consistent with the content of palace lattice.
Since, there may be two kinds of situations, situation is first is that keying sequence is number, then corresponding nine palace in practical application

For sky, then according to the content information of each palace lattice, the determining palace lattice with the first password match in keying sequence aim at determining palace
Lattice simultaneously strike the palace lattice, if the palace lattice of impact are identical as the first password of keying sequence, the password obtained next time is still upper
One keying sequence, if the palace lattice of impact are different from the first password of keying sequence, the password obtained next time be will be updated.
After getting keying sequence for the second time, whether keying sequence and last keying sequence that judgement currently obtains
It is identical, if they are the same, then according to the content information of each palace lattice, determine the palace lattice with the second password match in keying sequence, if
Determining current password (namely second password) matched palace lattice with current password sequence, then aim at and strike the palace
Lattice, until having determined the palace lattice with each password match in current password sequence.Wherein, after the second password password determination side
Formula is identical as the method for determination of second password, is not described one by one.
When judging the keying sequence currently obtained and whether identical last keying sequence, if obtained current password sequence
Column are not sky, and different from previous keying sequence, illustrate that the last palace lattice determined are different from the password in keying sequence, then
The step of execution handles palace table images, obtains the coordinate information of each palace lattice.
In practical applications, it is considered as knowledge when the password of acquisition has only changed one compared with last for situation one
Not mistake is reuptaked password image and is identified.It, may when the password of acquisition and the last password obtained have changed multidigit
It is last time impact mistake caused by either equipment receives signal but do not make a response at the appointed time, at this time no matter in the lattice of palace
Number whether change, will again according to the keying sequence newly obtained sequence strike palace lattice.When acquisition keying sequence with
Last time obtain keying sequence compared to do not change and in the lattice of palace number do not change, it may be possible to recognition speed is fast, and equipment receives
It does not take action also after secondary recognition result, causes the image of camera typing to have not occurred variation or equipment inclined due to shooting
Difference or other situations cause to have reacted but nine grids panel is uninfluenced and change.Due to that can not judge equipment whether
It makes a response, therefore, continues to read image and be identified, do not send data.It, may when the number duplicated in the lattice of palace
Be due to handwritten numeral it is excessively similar caused by identify mistake, or handwritten numeral is unsharp when due to taking the switching of palace lattice
Moment reuptakes image and is identified.When password does not change, number changes in the lattice of palace, it is believed that last time strikes successfully,
Panel has been switched to next bit password, and such case searches next bit password by the number of blows of record Gong Gezhong's
Position exports target palace lattice serial number to equipment.
For situation two, if obtained current password sequence is sky, according to the coordinate information of each palace lattice, from the palace lattice
In image, the corresponding image of each palace lattice is extracted；For the corresponding image of each palace lattice, the feature of the corresponding image of palace lattice is extracted
Collection, calculates the similar features number in the feature set of the palace lattice and the feature set of other each palace lattice, calculates the palace lattice and other palaces
The corresponding similar features number of lattice and value；It will be determined as password with the smallest palace lattice of value.
In specific implementation, after the image for extracting each palace lattice, for the corresponding domestic image of each palace lattice, Jiang Gegong
The image of lattice, which is input to, to be previously-completed in trained image recognition model, and the feature set of the corresponding image of palace lattice is obtained, comparison
The feature set of the palace lattice and feature set with other palace lattice, respectively obtain the similar features number of the palace lattice Yu other palace lattice, count
Calculate the similar features number of the palace lattice and other palace lattice and value.It will be determined as different palace lattice with the smallest palace lattice of value.
For example, the picture material in palace lattice 2 is character image with reference to Fig. 3, the picture material of other palace lattice is automobile figure
Picture, then, the similar features number that palace lattice 2 and other palace lattice are calculated can be fewer, and the similar features number of other palace lattice
Mesh can be relatively more, finally, the palace lattice 2 of calculating and the similar features number of other palace lattice and be worth understand it is very low, it is thus determined that palace lattice 2
For different palace lattice, that is, password palace lattice.
