For X-direction, terminal broadside be Y direction, terminal long side direction be Z-direction.
Obtain the implementation of human eye sight of user and specifically include following three step:
1) human eye pupil coordinate is obtained
Terminal passes through camera collection image information, and the image information of collection includes the face of user, terminal
The oculopupillary Y of people on face, Z coordinate b, c is obtained by Eye Recognition in the image information gathered.
Terminal determines the facial contour of user in the image information gathered according to face recognition technology, and obtains
The size of facial contour.
Concrete, Fig. 4 is the image information of camera collection, the size such as Fig. 4 of the facial contour that terminal obtains
Shown in (a) and Fig. 4 (b).
Terminal obtains user's face to terminal screen according to size and the default mapping relations table of facial contour
Oculopupillary X-coordinate a of vertical dimension, i.e. people.Described default mapping relations table is for characterizing the big of facial contour
Little and distance between mapping relations.
As shown in Fig. 4 (a) and Fig. 4 (b), according to " remote little near big " principle, face and terminal screen away from
Close to more, the facial contour of camera collection is the biggest (Fig. 4 (a)), and face is the most remote with terminal screen distance,
The facial contour of camera collection is the least (Fig. 4 (b)).Face can be taken turns by equipment manufacturers according to this principle
Set up between wide size and face and terminal screen distance and quantify mapping relations, and by this mapping relations collection cooperation
Store in the terminal for default mapping relations table.When after camera collection to the size of facial contour, according in advance
If the mapping relationship searching face in mapping relations table and terminal screen distance, it is derived from the oculopupillary X of people
Coordinate a, and then obtain human eye pupil coordinate a, b, c.
2) eyeball sphere centre coordinate is obtained
As it is shown in figure 5, in the image information gathered, terminal identifies human eye by Eye Recognition,
Obtain the Y at two canthus of human eye, Z coordinate Y1, Z1 and Y2, Z2 the most respectively.Terminal is according to straight line mid-point formula
(in Y, in Z)=[(Y1+Y2), (Z1+Z2)], obtains the oculocentric Y of people, Z coordinate, i.e. the eyeball centre of sphere
Y, Z coordinate B, C.Such as, as the Y at two canthus, when Z coordinate is respectively (2,15) and (4,15),
(2,15) and (4,15) being substituted into above-mentioned formula, it is thus achieved that the Y of the eyeball centre of sphere, Z coordinate is (3,15), B
Being 3, C is 15.
Then, the X-coordinate of the eyeball centre of sphere is obtained.Owing to human eye pupil is positioned at eyeball surface, and the eyeball centre of sphere
It is positioned at the center of eyeball spheroid, so being spaced the distance of an eyeball radius the most in the X-axis direction,
Terminal will be 1) in the oculopupillary X-coordinate of people and the default eyeball radius that obtain sue for peace, be derived from eyeball ball
X-coordinate A of the heart, and then obtain eyeball sphere centre coordinate A, B, C.
In embodiments of the present invention, the default eyeball radius that manufacturer is preset in terminal is 15mm (millimeter),
15mm is the eyeball radius reference value with statistical significance.15mm in the embodiment of the present invention is only example
Illustrating, in actual application, manufacturer can also obtain the eyeball radius of targeted user population according to racial difference
Reference value, and be preset in terminal.
As shown in Figure 6, Fig. 6 is the birds-eye perspective of user's head, i.e. the top view of human eye eyeball.Such as Fig. 6
A, shown in (), the explanation of above-mentioned acquisition eyeball centre of sphere X-coordinate A is to overlap with the eyeball centre of sphere based on human eye pupil
Situation, i.e. user face the explanation that the situation of terminal screen is carried out, in this case, the oculopupillary X of people
Distance between X-coordinate A of coordinate a and the eyeball centre of sphere is for presetting eyeball radius 15mm.And at Fig. 6 (b)
In, when user looks side ways terminal screen, between oculopupillary X-coordinate a of people and X-coordinate A of the eyeball centre of sphere
Distance less than preset eyeball radius 15mm.In such cases, the realization of X-coordinate A of the eyeball centre of sphere is calculated
Mode is specific as follows:
Terminal obtains the difference between people oculopupillary Y coordinate b and the Y coordinate B of the eyeball centre of sphere by photographic head
Value, i.e. 1 in Fig. 6 (b).Then default eyeball radius is calculated in X-axis according to Pythagorean theorem
G in component value, i.e. Fig. 6 (b).Terminal using component value g as actual eyeball radius and the oculopupillary X of people
Coordinate a sues for peace, and obtains X-coordinate A of the eyeball centre of sphere.
It should be noted that in user's head relative position relation with terminal, due to three-dimensional system of coordinate
Initial point is positioned at end side, so the eyeball centre of sphere is more remote than the distance of human eye pupil to terminal to the distance of terminal, because of
And X-coordinate A of the eyeball centre of sphere is behaved oculopupillary X-coordinate a and eyeball radius sum, rather than difference.
3) human eye sight of user is obtained
Getting human eye pupil coordinate a, b, c and eyeball sphere centre coordinate A, after B, C, according to " 2 points
One line " principle calculating linear equation, the straight line represented by this linear equation is the human eye sight of user.?
In the embodiment of the present invention, three-dimensional system of coordinate cathetus equation embodies with the form of spatial parameter equation, and two
In dimension coordinate system, linear equation can also be presented as the form of such as Y=kX+b, in embodiments of the present invention,
Spatial parameter equation is only the example to linear equation and illustrates, the avatar of actual application cathetus equation
It is not limited only to this.
Concrete, shown in spatial parameter equation such as formula (1):
Wherein, parameter t is arbitrary value, formula (1) does deformation and can obtain formula (2):
By human eye pupil coordinate a, b, c are as X1, Y1, Z1Substitute into formula (1), by eyeball sphere centre coordinate A, B, C
As X2, Y2, Z2Substitute into formula (1), can obtain formula (3):
Formula (3) is required linear equation, i.e. represents the linear equation of human eye sight.
203, terminal obtains human eye sight tested point coordinate on a terminal screen.
After step 202 gets the linear equation of expression human eye sight, obtain people by this linear equation
An eye line intersecting point coordinate on a terminal screen, i.e. tested point coordinate.Owing to terminal screen place plane is three
The YZ plane of dimension coordinate, so the X-coordinate of any point is 0 on terminal screen, substitutes into step by X=0
In formula (3) in 202, human eye sight tested point coordinate on a terminal screen can be obtained.
Such as, as human eye pupil coordinate a, b, c are 2,3,5, eyeball sphere centre coordinate A, when B, C are 4,2,6,
Concrete numerical value is substituted into formula (3) and then has a formula (4):
X=0 is substituted into formula (4) Y=4, Z=4 can be obtained, it follows that tested point coordinate m, n are 4,4.
It should be noted that previous embodiment is mentioned, the coordinate dimensions that terminal obtains should be tieed up with place referential
Degree is consistent, and the tested point coordinate i.e. obtained in three-dimensional system of coordinate should be l, m, n.Due to tested point coordinate with
Standard point coordinate belongs to the coordinate points on terminal screen, and its X-coordinate perseverance is 0, and X-coordinate judges ratio to follow-up
Step relatively does not has actual influence, so for simplifying technical scheme, by fixed to tested point coordinate and standard point coordinate
Justice is two-dimensional coordinate point.
If 204 tested point coordinates mate with preset standard point coordinates, then screen described in terminal unlocking.
Preset standard point coordinates j, k are manufacturer or user preset storage conduct unblock rule in the terminal
Coordinate points, it is also possible to be the coordinate points that is randomly assigned of terminal when step 201 starts and unlocks.
Terminal judges tested point coordinate m, n and preset standard point coordinates j, whether k mates, when such a match occurs,
Represent that the unblock of user " indicates " and unlocks rule match, terminal unlocking screen；When both do not mate,
Representing that the unblock of user " indicates " not mate with unblock rule, terminal does not understands lock screen, and order performs again
Step 201, to step 203, reacquires tested point coordinate m, n.
The matched rule that tested point coordinate mates with preset standard point coordinates has two:
1) when tested point coordinate is identical with preset standard point coordinates, i.e. tested point Y coordinate m and preset standard
Point X-coordinate j is identical, and when tested point Z coordinate n is identical with preset standard point Y coordinate k, tested point is sat
Mark mates with preset standard point coordinates.
2) the most harsh for avoiding unlocking rule, unlock that the match is successful that rate is low, it is also possible to suitably relax unblock
Join standard, tested point coordinate m, n will fall into preset standard point coordinates j, be defined as in certain limit around k
Unlock rule match.Concrete, the coupling standard unlocking rule is to be the center of circle with standard point coordinate j, k,
Border circular areas with L as radius is defined as coupling circle (region), and tested point coordinate m, as long as n falls into this coupling
It is in circle and unlocks successfully.Wherein, L is the coupling radius of circle that terminal manufacturer is arranged according to physical condition, example
If L can be 5mm.
Above-described embodiment is illustrated as a example by unlocking rule using a standard point coordinate, optionally, also
Using at least two standard point coordinate as unlocking rule, terminal can be unlocked operation.Concrete, if depending on
Multiple tested point coordinates of secondary acquisition and multiple preset standard point coordinates Corresponding matchings, then terminal unlocking screen,
Wherein, terminal screen successively presents or presents the multiple points corresponding with multiple preset standard point coordinates simultaneously.When
When terminal screen successively presents or presents multiple corresponding with multiple preset standard point coordinates simultaneously, unlock rule
The most not only comprise each standard point coordinate, further comprise the sequencing of multiple standard point coordinate matching.
Concrete, terminal order obtains multiple tested point coordinates, when multiple tested point coordinates occur with order respectively
