Unanimously.
In embodiments of the present invention, the decoding graphics proportion actually entered is such as 700*220, and what this step was done is to incite somebody to action
Decoding figure is zoomed in and out in cipher graphic ratio 600*200, and X-direction shorten to 600, and Y-direction shorten to 200, such as Fig. 7 and figure
Shown in 8.
S14：Determination step；
Two width decoding graphics field after S13 steps scaling is compared with cipher graphic region respectively, if
The corresponding coordinate points of wherein width decoding figure coordinate points similarity corresponding with cipher graphic reaches in two width decoding figure
80% or 80% or more, then judge that decoding figure meets the requirements, and unlocks successfully, otherwise, unlock failure, inside determination step most
More there are one can be judged as correctly decoding figure.Specifically, in embodiments of the present invention, the figure (X after scaling1, Y1)
As new origin, all coordinate points are numbered by the sequence of X-coordinate, Y coordinate from small to large, form coordinate 1, coordinate 2, sits
It is all coordinate points quantity to mark 3...... coordinates B, B, and all coordinates of coordinate points all on figure and cipher graphic are clicked through
Row compares.
In embodiments of the present invention, Fig. 7 and Fig. 8 figure coordinates recorded are compared with cipher graphic Fig. 3, if figure
The coordinate of figure and the coordinate similarity of cipher graphic Fig. 2 reach 80% or more in 7 or Fig. 8, then judge that decoding figure conforms to
It asks, unlocks successfully.If similarity is not up to 80%, failure is unlocked.
The specific comparison process of figure and test pattern after scaling is mainly compared by following two aspects, specifically
Ground, 1, coordinate points quantity：The error of the coordinate points quantity B of figure and cipher graphic coordinate points quantity A should be ± 10% after scaling
Within；2, error of coordinate：Using cipher graphic as template, the coordinate of coordinate points is compared one by one, and error of coordinate can connect within ± 3
By.Corresponding coordinate (such as cipher graphic coordinate 1 (256,135), contracting are found on the figure of the coordinate 1 of cipher graphic after scaling
Coordinate 1 (255,136) on figure after putting, then coordinate 1 meet unlocking requirements), successively by coordinate 2, coordinate 3...... coordinates A
It is compared, corresponding coordinate point can be found on the figure of 80% coordinate after scaling by having, then judges to unlock successfully.
