After the preset reference image for obtaining user, when user currently carries out handwriting input, user is being obtained in hand
After user images when writing input person's handwriting, the user images and preset reference image are carried out into aspect ratio pair, determine hand-written inclination
Angle.Because preset reference image and the user images currently clapped are all based on what identical camera was clapped, i.e. shooting angle
Degree, acquisition parameters it is identical, it is thus possible to pass through contrast two width images in same characteristic features element pixel coordinate can determine it is hand-written
Angle of inclination.
In addition, according to the mode of handwriting Orientation, it is determined that the hand-written angle of inclination of person's handwriting is implemented as：
It is determined that the angle between the default frame of the presentation direction of input person's handwriting and touch-screen；
Angle reference corresponding with the default input person's handwriting is write into angle to be compared, hand-written inclination angle is determined
Degree.
It is the angle from the writing effect of user determining hand-written angle of inclination in which.Assume the hand on touch-screen
It is a rectangular box to write region, and four of the rectangular box are corresponding parallel respectively while with the four of screen, it is possible to understand that
, in ideal conditions, if the user while it is horizontal to write one in the region, then the horizontal stroke should be parallel to the rectangular box
Top, it is also parallel to the upper side frame of touch-screen.
It is similar with the acquisition process principle of above-mentioned preset reference image, in the manner, can be in the normal handwriting input of user
Under pattern, trained by substantial amounts of word, collection obtains user when various strokes are write, and every kind of stroke is relative to touch-screen
The angle of certain frame.For for same unicursal, nuance is had when due to writing every time, can be by a large amount of books
