Embodiment
The invention provides the method and system of touch-screen stabilization, to make the purpose of the present invention, technical scheme and effect more
Plus it is clear, clear and definite, referring to the drawings and give an actual example that the present invention is described in more detail.It should be appreciated that described herein
Specific embodiment only to explain the present invention, is not intended to limit the present invention.
Fig. 1 is referred to, Fig. 1 is the method flow diagram of touch-screen stabilization of the present invention.As shown in figure 1, institute of the present invention
The method for the touch-screen stabilization stated, including：
Step 101, when detecting touch operation, obtain specify touched in the period point coordinates a little.
When detecting user to the touch operation of touch-screen, obtain specify touched in the period point coordinates a little, these points
Coordinate had both included the point coordinates of the point of user's Active touch, also included the point coordinates that user is not intended to the point of touch, it is not intended to touch
Touch the touch such as carried out due to shake.The specified period is 100 milliseconds.
Step 102, the point spacing according to any two touch point of point coordinates calculating, and point is smaller than default threshold value
Two touch points are placed in same point set.The point spacing for calculating any two touch point according to point coordinates is to calculate each touch according to point coordinates
The point spacing a little between other touch points is touched, two touch points that point is smaller than into default threshold value, which are placed in same point set, is
A finger main points are smaller than default threshold value and just corresponding two touch point of the spacing are put into same point set, and point set is advance
Create.The step 102, specifically refers to Fig. 3, and Fig. 3 is the refined flow chart of step 102.As shown in figure 3, the step
102 specifically include：
Step T10, one point set of establishment, and a touch point is placed in point set；
Step T20, judge outside point set whether there is touch point, if so, perform step T30, if it is not, then step T50 terminate；
Step T30, the point spacing for calculating each touch point outside each touch point and point set in point set, and judge that described spacing is
It is no to be less than default threshold value, if so, step T40 is then performed, if it is not, then performing step T10；
Step T40, the corresponding touch point of point spacing less than threshold value is placed in point set, and returns to T20.
Step 102 specific steps as described above, create a point set first, any one touch point are placed in point set, root
Strong point coordinate obtains the point and the point spacing of the outer touch point of point set, and the touch point that point is smaller than into default threshold value is placed in described
Point set in, each point spacing touched with each touch point outside point set in point set is obtained again, point is smaller than default threshold value
Touch point be placed in described point set,
In above-mentioned deterministic process, if in the absence of the touch point less than default threshold value, a point set is created again,
And touch point is placed in the point set one by one by point set local official ... ... the like, untill touch point is not present outside point set.
Step 103, the characteristic point for obtaining point set, the characteristic point are to be averaged with the point spacing of other touch points in point set
It is worth minimum touch point.The characteristic point for obtaining point set specifically includes three below step：
Point spacing in first step, calculating point set between each touch point and other touch points, and each touch calculated
The point spacing average value of point；
Second step, the point spacing average value of each touch point compared, obtain minimum point spacing average value, and obtain most
Third step is performed behind the small corresponding touch point of point spacing evaluation of estimate；
Third step, determine whether other point sets exist, if so, then performing first step；If it is not, then terminating.

2；
Step S202-3, calculating Q3With Q1、Q2、Q4The distance between be respectively：30.4、29.7、10.3 ；By these away from
Arithmetic mean of instantaneous value is asked to be assigned to a, i.e. a=23.5 from value, because a (now a=23.5) is more than b（Now b=20）, therefore do not change b with
K value, i.e. b=20, k=2；
Step S202-4, calculating Q4With Q1、Q2、Q3The distance between be respectively：29.5、29.2、10.3 ；By these away from
Arithmetic mean of instantaneous value is asked to be assigned to a, i.e. a=23 from value, because a (now a=23) is more than b（Now b=20）, therefore do not change b's and k
Value, i.e. b=20, k=2；
Step S202-5, the characteristic point of this feature point set are QkThat is, Q2, i.e. P2(550,516) 。
