S201：Detect the region that default mark inputs the multiconductor screen on object to be identified；
In general, by the method for setting unlike signal on different objects to be identified touch-screen can be realized to difference
The identification of object, the shape in the region produced because of contact of the index point in different marks with touch-screen is different, therefore,
Different marks can represent different objects, need to only pre-set one-to-one relationship between different objects and unlike signal i.e.
Can.
S202：According to pre-set database, the shape in the region and corresponding contact are determined；
The database includes at least the one-to-one relationship between region and shape and contact；
Wherein, the characteristic feature can be preferably the corresponding contact of shape of the shape and the region in the region.

The angle parameter of the shape in region is stated, determines the rotation angle of the object.
As shown in figure 3, the method described in the present embodiment is illustrated：
The mark of triangle is set on object A, ellipse mark is set on object B, object A and object B are placed on tactile
Touch on screen, touch-screen detects that the region of object A inputs is triangle, and the region for receiving object B outputs is ellipse, pre-
If database in, search with the shape of Region Matching, when finding triangle, determine the ID of object corresponding with triangle
For the ID of object A, and the contact using contact corresponding with triangle as object A.Equally, it can determine the ID of object B and touch
Point.
In the prior art, first will be according to the corresponding contact of signal of mark input, then the spatial relation of foundation contact
Different objects is distinguished, as shown in figure 4, different position relationships is constructed using three marks respectively on object A and object B,
When object A is placed on the touchscreen, touch-screen first determines the corresponding contact of mark on object A, then according to the contact
Spatial relation, such as isosceles triangle is formed, determine the ID of object A.Therefore, the distance between the mark on object A is such as
Fruit is too near, then cannot be distinguished by out different index points, then is possible to two marks being determined as a contact, if indicated
It is small, then it may be considered noise, then be determined without contact, therefore, the area to index point and spacing will in the prior art
Ask.
It can be seen from the above that the recognition methods based on multiconductor screen described in the present embodiment, according in default database
Correspondence between the input signal of shape and contact and mark, the touch area of mark on the touchscreen is converted to being capable of generation
Table and shape and the contact for distinguishing this mark, different marks is distinguished with this, and then identifies different objects.With existing skill
Art is compared, the method described in the present embodiment identifies different objects while determining to indicate corresponding contact, i.e. object
Identification is not that therefore, size and its spacing for index point do not require, so as to use based on determining contact
With the identification of various objects.
Another recognition methods based on multiconductor screen disclosed by the embodiments of the present invention, as shown in figure 5, including：
S501：Determine shape of each default mark to the region of multiconductor screen input；
S502：Determine the corresponding contact of each shape；
S503：Each default mark and the correspondence between respective shape and contact are stored, to create
Database；
Wherein it is determined that and store shape of any one mark in each default mark and corresponding contact
Process is：
Detect the region that default mark inputs the multiconductor screen on current object；
Adjust filter value so that the current shape in the region and the region be one-to-one relationship, record with it is described
Corresponding first filter value of first shape；
The filter value refers to carry out the signal of mark input the filter value that filtering uses（The threshold value of image filtering）, mistake
Filter value is different, then the shape that can be obtained is different.
Receive the first contact of current first shape input by user；
First contact can be any point in the region of the first shape of user's selection.
Store the correspondence of first filter value, the first shape and first contact.
I.e.：Stored in database for different marks and its one-to-one characteristic feature, i.e. pair of shape and contact
It should be related to, the definite method of each characteristic feature is identical.Therefore, different marks can correspond to different characteristic features.
S504：Using the different filter values stored in the database, the region is filtered；
Filtered successively using the filter value stored in database, it is therefore intended that, determine the shape stored in database.
S505：It will be matched from the different regions being worth to of filtering with the shape stored in the database；
, it is necessary to the shape that will be stored in the shape in obtained region and database after being filtered using each filter value
Shape is matched.
S506：When the region is the first shape, the first shape and corresponding with the first shape is determined
The first contact be characteristic feature corresponding with the region.
A preferably shape corresponds to a contact in the present embodiment, and contact can be barycenter of shape etc..
It should be noted that when postrotational shape is passed through in the region for the first shape, according to the shape
In parameter, be first shape by the shape recognition.That is, the method described in the present embodiment, if object carries out
Rotation, or the angle of discharge are changed, then also can be according to the parameter in shape, such as the pass on the angle of triangle and side
System, identifies the shape in the region that object inputs touch-screen.
S507：According to the characteristic feature, the default mark is identified, to identify the object.
I.e. in the database after successful match position relationship, will characteristic feature corresponding with position relationship be determined as it is to be identified
The corresponding characteristic feature in contact of mark input on object.
S508：Based on the information of the object identified, relevant application program is run.
Wherein, the information of the object identified, including the information such as the mark of object, position, rotation angle.This step is specific
Including：According to the object information identified, to run relevant application program；Or the information output for the object that will identify that
Relevant application program, to change the state of application program operation.
For example, touching screen display chessboard, different chess pieces is placed on the diverse location of chessboard.When user changes particular pawn
Position after, application program identifies the mark of corresponding chess piece and new position, is then produced not according to corresponding game rule
Same audio, to provide novel user experience.
In practical applications, it is first after the original array image that touch Controller obtain touch input signal
Different filtering thresholds is first used successively, is carried out image filtering, is then carried out form fit, if after successful match, at this
It is generally indicated at 1 point, externally exports the representative coordinate under the pattern（Contact）, and current matching can be further exported as needed
The image aspects gone out（Including but not limited to information such as rotation angles）.
In the prior art, when needing the differentiation of two different objects of completion, at least need to set two on each object
A above index point, and so on, when needing to identify multiple and different objects, then need more index points to distinguish,
But current multiconductor touch screen identifies that multifinger quantity can not possibly be too big at the same time, for example, current multiconductor touch screen is at the same time
Can identify the output of 10 contacts, and this is far from enough for the identification of multiple objects, the object different using three as
Example, will identify these three objects, then needs to take 9 contacts, if four different objects, then touch-screen can not carry out
Identification.
As it can be seen that existing limited based on the object identification method of multi-contact touch screen be subject to multiconductor screen characteristics, know
During not different object, the quantity of the contact of occupancy is excessive.
Method described in the present embodiment, is pre-created including indicating the database with the correspondence of characteristic feature, right
During mark is identified, according to the database, shape and its contact indicated is determined, because being known in object
During other, it will be respective contact without object identification, and therefore, the quantity of contact can be determined as to one, therefore energy
Enough reduce the quantity of the contact of the touch-screen shared by object identification.
