It considers in the prior art, just to can determine that the touching when the directive scanning optical path of institute is blocked in touch point in the present invention
It touches a little as true touch point, when touch point is smaller, cannot block the directive scanning ray of institute, which will be by
Ignore.And then expect, when determining touch point, touch point does not need to block a directive scanning optical path.In this way, in existing skill
The smaller touch point that can not be got in art can determine that method is determined by the touch point of this programme.
The principle of infrared touch panel is as shown in Figure 1, there are two infrared emissions while with two infrared receivers, infrared emission side
It is oppositely arranged with infrared receiver side.Infrared transmitter is arranged on infrared emission side, infrared receiver is arranged with infrared receiver on side
Device.As shown in Figure 1, an infrared transmitter can emit infrared ray to multiple directions.
The technical term in the present invention is explained below:
Scanning optical path: the infrared ray of the infrared transmitter transmitting on infrared emission side.
Scanning direction: scanning direction is the direction of one group of scanning optical path with slope on touch screen.Infrared transmitter can be with
Emit the infrared ray of different angle, infrared transmitter specific for one can correspond to the scanning light of a plurality of different angle
Road, each angle are known as a scanning direction.
Touch area: a specific scanning direction corresponds to one group of parallel sweep optical path, when there is touch to occur, touching
It touches a meeting and shelters from continuous several in these parallel sweep optical paths, under same scanning direction, the scanning that is continuously blocked
Region between optical path is touch area.The scanning optical path of the scanning direction of correspondence touch area in each touch area is equal
It is blocked.As shown in Fig. 2, a, b, c and d are 4 scanning optical paths of the same scanning direction that touched point is blocked, then a scans light
Region between road and d scanning optical path is touch area.For convenience of statement, when indicating touch area in subsequent diagram,
The outermost scanning optical path in touch area is only drawn, i.e., only draws a scanning optical path and d scanning optical path；
Another situation, when touch point is smaller, has only blocked a scanning optical path, then the scanning optical path that this is blocked
Scanning direction under, the region between two scanning optical paths adjacent with the scanning optical path that is blocked is determined as touch area.
Illustrate technical concept of the invention below with reference to Fig. 3.Assuming that having A, B and C totally 3 scanning direction detections in Fig. 3
Touch area is arrived, a1 and a2 are two touch areas on A sweep direction, and b1 and b2 are two touches on B-scan direction
Region, c1 and c2 are two touch areas on C-scan direction.Conventionally, as when all sweep is blocked in touch point
When retouching direction, i.e., such as No. 1 region in Fig. 3, when having blocked tri- scanning directions A, B and C, it just can determine that No. 1 region is touch point.
And No. 2 regions in Fig. 3 have been due to only having blocked B-scan direction and C-scan direction, in the prior art, it cannot be recognized
Make touch point.And in reality, often there are many points smaller as No. 2 regions, it cannot be accurate in the prior art
Identify.
Aiming at the problems existing in the prior art, as shown in figure 4, the embodiment of the present invention provides a kind of touch point determination side
Method is executed by touch screen or its corresponding control unit (such as CPU, MCU etc.), and in one implementation, the present invention is real
Applying method provided by example includes S101-S108:
S101: the touch area on touch screen under each scanning direction is obtained.
S102: the most scanning direction in touch area is determined as target direction.
It should be noted that then optionally one of them is swept when there is the touch area of identical quantity on multiple scanning directions
Retouching direction is target direction.As shown in figure 5, shared A, B, C and D, 4 scanning directions detect touch area, A sweep direction
Under have two touch areas a1 and a2, have two touch areas b1 and b2 under B-scan direction, have c1 and c2 two under C-scan direction
There are two touch areas d1 and d2 in a touch area under the scanning direction D.There are two touch areas for each scanning direction, then may be used
Optional one of scanning direction is determined as target direction.
If it is determined that target direction on touch area and other scanning directions on touch area there is no intersecting area,
The touch area on the target direction determined then is determined as invalid touch area；Then it redefines target direction: will remove
It is determined as the most scanning direction in the touch area other than invalid touch area and is determined as target direction.
S103: the intersecting area of the touch area on the touch area and other scanning directions on target direction is obtained.
Since scanning direction is different, there can be the case where touch area intersection.When the intersection of two touch areas,
It can confirm that the intersecting area is likely to be touch point, the present invention determines the base of touch point with the intersecting area of touch area
Plinth.
S104: by each touch area on target direction, the most intersecting area in affiliated touch area is determined as touching
It touches a little.
Since the touch area on same scanning direction can not intersect, intersection is all different scanning direction
Touch area.Therefore, the touch area belonging to the intersecting area is more, illustrates to detect the corresponding scanning direction of the intersecting area
More, which more may be real touch point.Therefore, the present invention will be in each touch area on target direction
The most intersecting area in affiliated touch area is determined as touch point in intersecting area.
As shown in figure 5, determine that the scanning direction D is target direction, and in the touch area d1, touching belonging to No. 3 intersecting areas
Touching region has 4, and touch area belonging to other intersecting areas is not above 4 in the touch area d1, therefore, by No. 3 phases
Region is handed over to be determined as touch point.In the touch area d2, touch area belonging to No. 4 intersecting areas has 3, in the touch area d2
Other intersecting areas belonging to touch area be not above 3, therefore No. 4 intersecting areas are determined as touch point.
S105: all touch areas belonging to touch point are determined as invalid touch area.
As shown in figure 5, when determine No. 3, No. 4 intersecting areas be touch point after, by Petting Area belonging to No. 3 intersecting areas
Touch area belonging to domain and No. 4 intersecting areas is determined as invalid touch area.After step S105, remaining touch area
Schematic diagram is as shown in Figure 6.
S106: the most scanning direction in the touch area in addition to being determined as invalid touch area is determined as target side
To.
After executing S105, remaining touch area is determined.With method identical with S102, target direction is determined.
As shown in fig. 6, detecting touch area, the touch area of each scanning direction there are two scanning direction A and C altogether
Number is 1, and therefore, optional wherein any one scanning direction is as target direction.
Determine A sweep direction be target direction, only one intersecting area of two touch areas, i.e., No. 5 intersecting areas in figure,
There is no need to compare the number of touch area belonging to intersecting area again, No. 6 intersecting areas are directly determined as touch point.
Technical solution provided in an embodiment of the present invention, determines touch point by the intersecting area of touch area, therefore on
S103-S106 is stated, it can be by repeatedly circulation, until without intersecting area.
S107: it after getting all touch points, executes and goes ghost point operation, and carry out rail to the touch point after ghost is put is deleted
Mark tracking.

Abscissa point and two ordinate points, integrate, can obtain the location information of 4 kinds of touch points, but actually only touch
Two points, other two touch point are exactly terrible point.Therefore, it after determining touch point, also needs to remove terrible point therein.Wherein,
The method of removal ghost point can be it is in the prior art any one, for example, can count only through some touch point to be determined
Without the number by the scanning optical paths of other touch points to be determined, for each touch point to be determined, if only by should be to
It determines that touch point is greater than preset threshold without the number of the scanning optical path by other touch points to be determined, then judges that this is to be determined
Touch point is true touch point, otherwise, judges the touch point to be determined for terrible point.After deleting ghost point, it can avoid to touch point
Erroneous judgement, improve touch point judgement accuracy.
The track following of touch point be also possible to it is in the prior art any one, for example, then being obtained after obtaining touch point
The touch point of lower scan cycle, calculate all touch points of two neighboring scan period to the distance between, wherein touch point
To including a touch point in every scan cycle in the two neighboring scan period；By all touch points to carry out fully intermeshing,
At least two touch points are obtained to sequence, wherein touch point was equal to for the first scan period to the number of the touch point pair in sequence
Touch point number, the first scan period be the two neighboring scan period in the touch point number least scan period；It counts respectively
Calculate each touch point to touch points all in sequence to the distance between the sum of, by the smallest touch point of sum of the distance to sequence
Column are used as matching double points sequence, wherein the line between two touch points of any touch point centering in matching double points sequence
For a touch track.Touch track can reflect the situation of movement of touch point.
S108, the logical coordinates for determining touch point and output.
According to the profile of touch point, the device coordinate of profile center of gravity is determined, wherein device coordinate is apart from screen upper left
The horizontal distance and vertical range at angle indicates.After getting the device coordinate of touch point, device coordinate is converted into logic and is sat
