Brain, UMPC (Ultra-mobile Personal Computer, Ultra-Mobile PC), PDA (Personal
Digital Assistant, personal digital assistant) etc., the embodiment of the present invention is not specifically limited in this embodiment.Further, the end
Infrared touch panel is at least configured in end, infrared touch panel is for detecting touch event.Wherein, touch event can be by
User's triggering, and the touch event can be click event, double click event, slip event etc., the embodiment of the present invention does not do this
It is specific to limit.
Fig. 2A is a kind of touch independent positioning method flow chart provided in an embodiment of the present invention, and this method is in terminal.Ginseng
See Fig. 2A, this method comprises:
Step 201: determining at least one candidate region in infrared touch panel.
Specifically, it is determined that the operation of at least one candidate region in infrared touch panel may include steps of (1) and
(2):
(1), the optical path formed in infrared touch panel is scanned, obtains the touch area on multiple scanning directions, respectively
Touch area on a scanning direction is the region where the optical path being blocked on each scanning direction.
Since each infrared transmitting tube in infrared touch panel can emit the infrared ray of multiple and different angles, so red
Usually will form the optical path for belonging to multiple and different slopes in outer touch screen, therefore, to the optical path formed in infrared touch panel into
It, can be every in multiple scanning direction based on the optical path formed in multiple scanning direction scanned infrared touch screens when row scanning
The corresponding one group of parallel light path with slope in a scanning direction.
In addition, for each scanning direction in multiple scanning direction, due to the corresponding one group of directional light in the scanning direction
Road, therefore, when the optical path formed in based on the scanning direction scanned infrared touch screen, if detected on the scanning direction
Continuous n optical path in this group of parallel light path is blocked, then the region where the continuous n optical path that can be blocked this determines
For a touch area on the scanning direction.Wherein, n is the natural number more than or equal to 1.
For example, as shown in Figure 2 B, multiple scanning direction is scanning direction 1, scanning direction 2, scanning direction 3 and scanning side
To 4, the corresponding one group of parallel light path in multiple scanning direction can then be touched based on multiple scanning direction scanned infrared
The optical path formed in screen.And for the scanning direction 1 in multiple scanning direction, it is assumed that this group on the scanning direction 1 is parallel
The continuous n optical path being blocked in optical path is optical path 1, optical path 2 and optical path 3, then can will be where optical path 1, optical path 2 and optical path 3
Region N be determined as a touch area on the scanning direction 1, and optical path 1 can be determined as being hindered in the N of the touch area
Optical path 3, is determined as the last item optical path being blocked in the N of the touch area by first disconnected optical path.
It should be noted that being scanned to the optical path formed in infrared touch panel, the touching on multiple scanning directions is obtained
The operation for touching region can also no longer be described in detail this with reference to other the relevant technologies, the embodiment of the present invention.
(2), the touch area in multiple scanning direction on any two scanning direction is overlapped, obtains infrared touching
Touch at least one candidate region in screen.
For example, as shown in Figure 2 C, any two scanning direction is scanning direction 1 and scanning direction in multiple scanning direction
3, and the touch area on scanning direction 1 is N0 and N1, the touch area on scanning direction 3 is N2 and N3, then can will scan
Direction 1 is overlapped with the touch area on scanning direction 3, obtain at least one candidate region in infrared touch panel be H1,
H2、H3、H4。
Step 202: the touching for each candidate region at least one candidate region, from multiple scanning direction
It touches in region, determines the associated region of the candidate region.
Specifically, for each touch area in the touch area on multiple scanning direction, judge the touch area
In first optical path being blocked and the last item optical path being blocked whether by the candidate region；When in the touch area
When first optical path being blocked and the last item optical path being blocked pass through the candidate region, determine that the touch area is to be somebody's turn to do
The associated region of candidate region.
For example, as shown in Figure 2 D, which is H1, which is N4, due to being hindered in the N4 of the touch area
First disconnected optical path and the last item optical path being blocked pass through candidate region H1, therefore, can be by the touch area
N4 is determined as the associated region of candidate region H1.
Wherein, judge whether be blocked in the touch area first optical path and the last item optical path being blocked pass through
When crossing the candidate region, the scanning direction where the touch area can be first determined, then determine on the scanning direction by the time
The maximum region of favored area determines first be blocked in the touch area when the touch area is located in the maximum region
Optical path and the last item optical path being blocked pass through the candidate region.
It should be noted that the maximum region on the scanning direction by the candidate region is on the scanning direction by being somebody's turn to do
Region where the continuous m optical path of candidate region.Wherein, m is the natural number more than or equal to 1.
For example, as shown in Figure 2 D, which is H1, which is N4, the scanning where the N4 of the touch area
Direction is scanning direction 2, then can determine the maximum region for passing through candidate region H1 on the scanning direction 2.Assuming that the maximum
Region is Z, since touch area N4 is in maximum region Z, hence, it can be determined that be blocked in the N4 of the touch area
One optical path and the last item optical path being blocked pass through candidate region H1.
Wherein it is determined that can determine the scanning direction pair when passing through the maximum region of the candidate region on the scanning direction
The slope for the optical path answered；When the slope of the corresponding optical path in the scanning direction is not present or is positive number, according to the scanning direction pair
The slope for the optical path answered calculates the corresponding first infrared hair of optical path on the first vertex on the scanning direction by the candidate region
Pipe position is penetrated, and calculates corresponding second infrared emission of optical path on the second vertex on the scanning direction by the candidate region
Region between first infrared transmitting tube position and the second infrared transmitting tube position is determined as passing through on the scanning direction by pipe position
Cross the maximum region of the candidate region；When the slope of the corresponding optical path in the scanning direction is 0 or is negative, according to the scanning side
To the slope of corresponding optical path, the corresponding third of optical path for calculating the third vertex on the scanning direction by the candidate region is red
Outer transmitting tube position, and calculate the 4th vertex on the scanning direction by the candidate region optical path it is corresponding 4th infrared
Region between third infrared transmitting tube position and the 4th infrared transmitting tube position is determined as the scanning direction by transmitting tube position
On by the candidate region maximum region.
It should be noted that the first vertex of the candidate region is to be blocked in the first touch area and the second touch area
The point that intersects of first optical path, the second vertex of the candidate region is quilt in the first touch area and the second touch area
The point that the last item optical path of blocking intersects, the third vertex of the candidate region are the be blocked in the first touch area
The point that the last item optical path being blocked in one optical path and the second touch area intersects, the 4th vertex of the candidate region
Intersect for the last item optical path being blocked in the first touch area and first optical path being blocked in the second touch area
The point arrived.Wherein, which is superimposed to obtain by the first touch area with the second touch area.
For example, as shown in Figure 2 D, which is H1, and the first vertex of candidate region H1 is point a, and the second vertex is
Point b, third vertex are point c, and the 4th vertex is point d, which is scanning direction 2, and the corresponding optical path in scanning direction 2
Slope be positive number, then can be calculated on the scanning direction 2 according to the slope of the corresponding optical path in scanning direction 2 by the time
The optical path corresponding first infrared transmitting tube position of the first vertex a of favored area H1, and calculate on the scanning direction 2 by being somebody's turn to do
The optical path corresponding second infrared transmitting tube position of the second vertex b of candidate region H1, it is assumed that the first infrared transmitting tube position is
Position 1, the second infrared transmitting tube position are position 2, then can be by the first infrared transmitting tube position 1 and the second infrared transmitting tube position
The region between 2 is set to be determined as passing through the maximum region of the candidate region on the scanning direction.
Wherein, it according to the slope of the corresponding optical path in the scanning direction, calculates on the scanning direction by the candidate region
When the corresponding first infrared transmitting tube position of the optical path on the first vertex, if the slope of the corresponding optical path in the scanning direction is not deposited
It can then determine that the first infrared transmitting tube position is (x0,0)；If the slope of the corresponding optical path in the scanning direction exists,
It can be by specifying formula to obtain the first infrared transmitting tube position as follows；
Wherein, (x, y) is the first infrared transmitting tube position, and (x0, y0) is the first vertex position, and y is the scanning direction pair
The slope for the optical path answered.
It should be noted that being calculated on the scanning direction according to the slope of the corresponding optical path in the scanning direction by the time
The optical path corresponding second infrared transmitting tube position on the second vertex of favored area calculates on the scanning direction by the candidate region
Third vertex optical path corresponding third infrared transmitting tube position, calculate on the scanning direction pass through the candidate region the 4th
The corresponding 4th infrared transmitting tube position of the optical path on vertex in above-mentioned steps 202 according to the oblique of the corresponding optical path in the scanning direction
Rate calculates the behaviour of the optical path corresponding first infrared transmitting tube position on the first vertex on the scanning direction by the candidate region
Make similar, the embodiment of the present invention repeats no more this.
Step 203: judging in the associated region of the candidate region with the presence or absence of the association area at least two scanning directions
Domain is specified associations region.
It should be noted that the optical path quantity being blocked in specified associations region is less than or equal to preset quantity.Wherein, in advance
If quantity can be preset, and preset quantity can be set it is smaller, such as preset quantity can be 1,2, the present invention implement
Example is not specifically limited in this embodiment.
For example, as shown in Figure 2 E, multiple scanning direction is scanning direction 1, scanning direction 2, scanning direction 3 and scanning side
To 5, which is that H1 determines the associated region of candidate region H1 from the touch area on multiple scanning direction
For N0, N2, N4, N5, N6, N7, and N0 is the associated region on scanning direction 1, and N2 is the associated region on scanning direction 3, N4
With the associated region that N5 is on scanning direction 2, N6 and N7 are the associated region on scanning direction 5.Assuming that being blocked in N0 and N2
Optical path quantity be all larger than preset quantity, the optical path quantity being blocked in N4, N5, N6 and N7 is respectively less than preset quantity, then can be with
Determine in the associated region of candidate region H1 there are the associated region on scanning direction 2 and scanning direction 5 to be specified associations
Region.
It should be noted that when there are the associated regions at least two scanning directions in the associated region of the candidate region
When being specified associations region, terminal can continue to execute following steps 204 to determine the true touch point in infrared touch panel；When
When being specified associations region there is no the associated region at least two scanning directions in the associated region of the candidate region, eventually
End can continue to execute following steps 205 to determine the true touch point in infrared touch panel.
Step 204: being when there are the associated regions at least two scanning directions in the associated region of the candidate region
When specified associations region, by the center line phase of the associated region at least two scanning direction on any two scanning direction
It hands over, obtains at least one candidate intersection point, from this at least one candidate intersection point, determine the true touch point in infrared touch panel.
For example, as shown in Figure 2 E, multiple scanning direction is scanning direction 1, scanning direction 2, scanning direction 3 and scanning side
To 5, which is H1, and there are the association areas on scanning direction 5 and scanning direction 2 in the associated region of candidate region H1
Domain is specified associations region, then can intersect the center line of the associated region on scanning direction 5 and scanning direction 2, obtain
At least one candidate intersection point is point e, f, g, h.At this time the candidate can be determined from this at least one candidate intersection point e, f, g, h
True touch point in the H1 of region.
Wherein, from this at least one candidate intersection point, when determining the true touch point in infrared touch panel, for this at least one
The candidate intersection point of each of a candidate's intersection point, judges whether there is the association for passing through candidate's intersection point on multiple scanning direction
Region；When there is the associated region for passing through candidate's intersection point on multiple scanning direction, determine that candidate's intersection point is infrared
True touch point in touch screen；When the uneven associated region existed by candidate's intersection point on multiple scanning direction, determine
Candidate's intersection point is the false touch point in infrared touch panel.
For example, as shown in Figure 2 E, multiple scanning direction is scanning direction 1, scanning direction 2, scanning direction 3 and scanning side
To 5, which is H1, and the associated region of candidate region H1 is N0, N2, N4, N5, N6, N7, and N0 is scanning direction 1
On associated region, N2 is the associated region on scanning direction 3, and N4 and N5 are the associated region on scanning direction 2, and N6 and N7 are
Associated region on scanning direction 5, which is point e, f, g, h.For the candidate intersection point e, due to scanning
Associated region N2 on direction 3 is without candidate intersection point e, so candidate intersection point e is the false touch point in infrared touch panel.For
Candidate intersection point f that is to say exist on multiple scanning direction and pass through since N0, N2, N5, N7 pass through the candidate intersection point f
Therefore candidate intersection point f can be determined as the true touch point in infrared touch panel by the associated region of candidate's intersection point f.For waiting
Intersection point g is selected, since N0, N2, N4, N6 pass through the candidate intersection point g, that is to say, is existed on multiple scanning direction by being somebody's turn to do
Therefore candidate intersection point g can be determined as the true touch point in infrared touch panel by the associated region of candidate intersection point g.For the time
Intersection point h is selected, since the associated region N2 on scanning direction 3 is without candidate intersection point h, so candidate intersection point h is infrared touch panel
In false touch point.
Wherein, when judging whether to there is the associated region for passing through candidate's intersection point on multiple scanning direction, for this
Each scanning direction on multiple scanning directions, the slope of the corresponding optical path in the available scanning direction, according to the scanning side
To the slope of corresponding optical path, the corresponding infrared transmitting tube position of optical path for passing through candidate's intersection point on the scanning direction is calculated；
When the infrared transmitting tube position being calculated is located in some associated region on the scanning direction, determine on the scanning direction
In the presence of the associated region by candidate's intersection point；When the infrared transmitting tube being calculated is not at any on the scanning direction
When in associated region, determine that there is no the associated regions by candidate's intersection point on the scanning direction.
It should be noted that being calculated on the scanning direction according to the slope of the corresponding optical path in the scanning direction by the time
Select the corresponding infrared transmitting tube position of the optical path of intersection point in above-mentioned steps 202 according to the oblique of the corresponding optical path in the scanning direction
Rate calculates the behaviour of the optical path corresponding first infrared transmitting tube position on the first vertex on the scanning direction by the candidate region
Make similar, the embodiment of the present invention repeats no more this.
Step 205: when the associated region being not present at least two scanning directions in the associated region of the candidate region is equal
When for specified associations region, the associated region of the candidate region is overlapped, at least one polygonal region is obtained, based on should
At least one polygonal region determines the true touch point in infrared touch panel.
Wherein, the associated region of the candidate region is overlapped, it, can be by one when obtaining at least one polygonal region
Associated region on a scanning direction is overlapped with the associated region on another scanning direction, obtains one group of new polygon
The new polygonal region of the group is overlapped, to obtain one again by region with the associated region on yet another scanning direction
The new polygonal region of group；It is so repeated up to the superposition for completing the associated region on all scanning directions, to obtain to the end
One group of polygonal region, last group of polygonal region are at least one polygonal region.
