Embodiment one：
A kind of flow chart of two-dimensional location method of first embodiment of the invention offer is illustrated in figure 1, for the ease of saying
It is bright, illustrate only the part related to the embodiment of the present invention.
In step S101, photosensitive mobile device is set, what the photosensitive mobile device included being provided with optical transmission window blocks dress
Put and some light sensitive diodes positioned at specified location.
In embodiments of the present invention, photosensitive mobile device is set first, wherein, photosensitive mobile device include radical occlusion device and
Some light sensitive diodes positioned at specified location.Radical occlusion device is different, then the position of light sensitive diode is different.Thus according to
The shape of radical occlusion device is arranged quantity and the position of light sensitive diode by developer.
Because of the difference of radical occlusion device, photosensitive mobile device has various.Wherein, preferably there are two kinds, be described more fully below.
The photosensitive mobile device of one of which includes a radical occlusion device, and one is provided with the radical occlusion device for light transmission
Triangle optical transmission window, it is preferred that the triangle optical transmission window be equilateral triangle optical transmission window, and three be used for receive from
The light sensitive diode of the light that triangle optical transmission window is passed through.Triangle optical transmission window is set first, three light are set with this
The position of quick diode, light forms one with triangle light inlet window through after triangle optical transmission window in perspective plane upright projection
The triangular windows projection of mouth identical, then arrange three light sensitive diodes and be located at respectively on three sides of triangular windows projection,
And the two of which opposite side of light sensitive diode is parallel with the side that triangular windows are projected, another two opposite side of light sensitive diode and triangle
The side of shape window projection is vertical, as shown in Figure 2.
Another kind of photosensitive mobile device also includes a radical occlusion device, and one is provided with the radical occlusion device for light transmission
Rectangle optical transmission window, also including three be located at specified location be used for receive from rectangle optical transmission window pass through light photosensitive two
Pole pipe.Rectangle optical transmission window is set first, the position of three light sensitive diodes is set with this, light passes through rectangle optical transmission window
Afterwards perspective plane upright projection formed one with rectangle optical transmission window identical rectangular window projection, then arrange these three photosensitive two
Two of which light sensitive diode is located at respectively on two adjacent drift angles of rectangular window projection in pole pipe, the two photosensitive two poles
Two groups of opposite side of pipe are respectively parallel to two of rectangular window projection and face side, and the length of side of rectangular window projection is more than photosensitive two pole
Two edge lengths sums of pipe（I.e. two light sensitive diodes are located at rectangular window and project when on two drift angles two light sensitive diodes not
Have the part of coincidence）, now the light-receiving area of the two light sensitive diodes is equal, is the 0.25 of its maximum light-receiving area
Times；Another light sensitive diode is located at the base relative with the rectangular window projected apex angle at above-mentioned two light sensitive diode place
On, and one group of opposite side of the light sensitive diode is parallel with the length of side that rectangular window is projected, as shown in Figure 3.
In step S202, by calculating light-receiving area of each light sensitive diode after the movement of photosensitive mobile device respectively
The light-receiving area variable quantity of some light sensitive diode transverse direction and longitudinal directions is obtained, and sets up some light sensitive diode transverse direction and longitudinal directions
The linear relationship of light-receiving area variable quantity and photosensitive mobile device moving coordinate
In embodiments of the present invention, when mobile photosensitive mobile device, directional light no longer vertically injects the saturating of radical occlusion device
Light window（It is different according to radical occlusion device, there are triangle optical transmission window or rectangle optical transmission window）So that light passes through optical transmission window
The window location of projection for being formed on perspective plane afterwards changes, and photosensitive mobile device is exactly light in the displacement of its place plane
Several times of the line through the displacement for projecting the window to be formed projection after optical transmission window on perspective plane（Wherein photosensitive mobile device is at it
The displacement of place plane is pre-set by developer with the multiple of the displacement that window is projected according to photosensitive mobile device）If, meter
Calculating the displacement of window projection can just calculate displacement of the photosensitive mobile device in its place plane.Meanwhile, radical occlusion device is wrapped
The light-receiving area of some light sensitive diodes for including also can change with the change that window is projected, photosensitive by calculating each respectively
The light-receiving area of diode understands that the light-receiving area sum of all light sensitive diodes can't become, and change is only single photosensitive
Diode light-receiving area, because the change in displacement of window projection is not easy to directly calculating, so that by diode sensitive surface
Long-pending change carrys out the displacement of calculation window projection.Wherein, the change size of light sensitive diode light-receiving area can be by photosensitive
The weak current change that the change of diode light-receiving area is produced is compared Jing after operational amplifier zooms into voltage signal.
Due to it is calculative be the two-dimensional movement coordinate of photosensitive mobile device, photosensitive mobile device only need to be in place plane
Upper movement, and the movement at grade of photosensitive mobile device can be broken down into transverse shifting and vertically move, thus under
Face is by respectively from the movement of horizontal and vertical both direction being described separately.Horizontal shifting of the photosensitive mobile device in its place plane
Dynamic displacement is exactly several times of the light through the lateral displacement of the window projection formed in perspective plane upright projection after optical transmission window
（The multiple of the displacement that wherein photosensitive mobile device is projected in the displacement of its place plane with window is by developer according to photosensitive movement
Device pre-sets）, and the lateral displacement of window projection is linear with the horizontal light-receiving area variable quantity of some light sensitive diodes
Relation.In the same manner, photosensitive mobile device is exactly in projection after light passes through optical transmission window in the displacement that vertically moves of its place plane
The several times of the length travel of the window projection that face upright projection is formed（Displacement of the wherein photosensitive mobile device in its place plane
Pre-set according to photosensitive mobile device by developer with the multiple of the displacement of window projection）, and the length travel of window projection
It is linear with longitudinal light-receiving area variable quantity of some light sensitive diodes.As long as thus calculating photosensitive mobile device respectively
The light-receiving area of each light sensitive diode after movement, calculates in photosensitive movement further according to the light-receiving area of each light sensitive diode
Some light sensitive diodes just can calculate photosensitive mobile device horizontal in the light-receiving area variable quantity of transverse direction and longitudinal direction after device movement
To and longitudinal direction location variation（That is the transverse and longitudinal coordinate of radical occlusion device moving coordinate）.
Below by according to the two kinds of photosensitive mobile devices mentioned in step S101 illustrating the horizontal stroke of why window projection
To displacement is linear with the horizontal light-receiving area variable quantity of some light sensitive diodes and the length travel of window projection with
Longitudinal light-receiving area variable quantity of some light sensitive diodes is linear, and step S102 is described in detail.
When the optical transmission window on the radical occlusion device of photosensitive mobile device is triangle, the photosensitive mobile device of movement is parallel
The angle of incidence of light changes, then radical occlusion device also changes therewith in the triangular windows projection that perspective plane projects, such as
Shown in Fig. 4（1st, 2,3 three light sensitive diodes are represented respectively）.Because the movement at grade of photosensitive mobile device can be by it
It is decomposed into the movement of transverse direction and longitudinal direction, thus below by respectively from the movement of horizontal and vertical both direction being described separately.Such as
Shown in Fig. 5, after photosensitive mobile device transverse shifting, the light-receiving area of only light sensitive diode 1 and light sensitive diode 2 becomes
Change, the light-receiving area of light sensitive diode 1 is reduced, and the light-receiving area of light sensitive diode 2 increased, and in general, Suo Youguang
Quick diode is exactly current in horizontal light-receiving area variable quantity（After i.e. photosensitive mobile device movement）The light of light sensitive diode 2
Area deducts the light-receiving area of light sensitive diode 1（S2-S1）, in Figure 5, AB is the lateral displacement of window projection, can by figure
Know, AB is equal to the light-receiving area incrementss of light sensitive diode 2（Or the light-receiving area decrement of light sensitive diode 1, or（S2-S1）/
2）Divided by length of side L of light sensitive diode, then it is multiplied byI.e.Thus, window projection lateral displacement with
The horizontal light-receiving area variable quantity of some light sensitive diodes is linear, thus the displacement of photosensitive mobile device transverse shifting also with
The horizontal light-receiving area variable quantity of some light sensitive diodes is linear, is become in horizontal light-receiving area according to light sensitive diode
Change amount just can calculate the lateral displacement of window projection, and then calculate photosensitive mobile device transverse shifting displacement.Thus can obtain
Arrive：DX=(S2-S1) * λ, wherein, dX represents the abscissa of photosensitive mobile device moving coordinate, and λ represents default Sensitirity va1ue,
S1 represents the light-receiving area of light sensitive diode 1, and S2 represents the light-receiving area of light sensitive diode 2, light sensitive diode 1 and photosensitive two pole
Pipe 2 is located at respectively on perspective plane on two waists of equilateral triangle.When radical occlusion device is vertically moved, as shown in fig. 6, photosensitive two pole
The light-receiving area of pipe 1, light sensitive diode 2 and light sensitive diode 3 all changes, and the length of side for now setting three light sensitive diodes is equal
For L, the distance that radical occlusion device is moved down is a, and this optical transmission window sentenced on radical occlusion device is calculated for equilateral triangle, due to
It is projected as equilateral triangle, it is known that angle O is 30 °, a=2b, therefore, the light-receiving area increment of light sensitive diode 3 is a*L（Namely
2b*L）, and the light-receiving area decrement of light sensitive diode 1 and light sensitive diode 2 is b*L, thus, it can be known that the photosensitive gross area is not
Become.Thus the longitudinal light-receiving area variable quantity for calculating light sensitive diode is S1+S2-S3.Now, the length travel of window projection
Equal to light sensitive diode 3 light-receiving area incrementss divided by light sensitive diode length of side L.Thus, the length travel of window projection
Linear with longitudinal light-receiving area variable quantity of some light sensitive diodes, thus photosensitive mobile device vertically moves displacement
It is linear with longitudinal light-receiving area variable quantity of some light sensitive diodes, according to light sensitive diode in longitudinal light-receiving area
Variable quantity just can calculate the length travel of window projection, and then calculate photosensitive mobile device and vertically move displacement.Thus can
Obtain：dY=SIt is vertical* λ, wherein, dY represents the vertical coordinate of photosensitive mobile device moving coordinate, and λ represents default Sensitirity va1ue, S1 tables
Show the light-receiving area of light sensitive diode 1, S2 represents the light-receiving area of light sensitive diode 2, light sensitive diode 1 and light sensitive diode 2
It is located on perspective plane on two waists of equilateral triangle respectively, S3 represents photosensitive two on perspective plane on the base of equilateral triangle
The light-receiving area of pole pipe 3.
When the optical transmission window on the radical occlusion device of photosensitive mobile device is rectangle, the photosensitive mobile device of movement, directional light
The angle of incidence of line changes, then radical occlusion device also changes therewith in the rectangular window projection that perspective plane projects, such as Fig. 7 institutes
Show（1st, 2,3 three light sensitive diodes are represented respectively）.The same shifting that the movement of photosensitive mobile device is decomposed into transverse direction and longitudinal direction
It is dynamic.Thus, when photosensitive mobile device transverse shifting, as shown in figure 8, the only light of light sensitive diode 1 and light sensitive diode 2
Area changes, and the light-receiving area increment of light sensitive diode 2 is equal to the light-receiving area decrement of light sensitive diode 1, thus
Understand, the horizontal light-receiving area variable quantity of light sensitive diode is S2-S1.The lateral displacement of window projection is equal to light sensitive diode 2
Light-receiving area incrementss（Or the light-receiving area decrement of light sensitive diode 1, or（S2-S1）/2）Divided by the side of light sensitive diode
Long half.Thus, lateral displacement and the linear pass of horizontal light-receiving area variable quantity of some light sensitive diodes that window is projected
System, thus the displacement of photosensitive mobile device transverse shifting also with the linear pass of horizontal light-receiving area variable quantity of some light sensitive diodes
System, according to light sensitive diode the lateral displacement of window projection just can be calculated in horizontal light-receiving area variable quantity, and then is calculated
Go out photosensitive mobile device transverse shifting displacement.Thus it is available：DX=(S2-S1) * λ, wherein, dX represents that photosensitive mobile device is moved
The abscissa of moving axes, λ represents default Sensitirity va1ue, and S1 represents the light-receiving area of light sensitive diode 1, and S2 represents photosensitive two pole
The light-receiving area of pipe 2, light sensitive diode 1 and light sensitive diode 2 are located at respectively on two drift angles of the rectangle on perspective plane.Work as sense
When light displacement device is vertically moved, as shown in figure 9, the light-receiving area of light sensitive diode 1, light sensitive diode 2 and light sensitive diode 3
All change, the length of side for now setting three light sensitive diodes is L, due to c+d=L, thus, it can be known that the photosensitive gross area is constant.
Thus the longitudinal light-receiving area variable quantity for calculating light sensitive diode is S1+S2-S3.Now, length travel of window projection etc.
In light sensitive diode 3 light-receiving area incrementss divided by light sensitive diode length of side L.Thus, window projection length travel with
Longitudinal light-receiving area variable quantity of some light sensitive diodes is linear, thus photosensitive mobile device vertically move displacement also with
Longitudinal light-receiving area variable quantity of some light sensitive diodes is linear, is become according to light-receiving area of the light sensitive diode in longitudinal direction
Change amount just can calculate the length travel of window projection, and then calculate photosensitive mobile device and vertically move displacement.Thus can obtain
Arrive：dY=SIt is vertical* λ, wherein, dY represents the vertical coordinate of radical occlusion device moving coordinate, and λ represents default Sensitirity va1ue, and S1 represents photosensitive
