Description
Technical field
The utility model relates to screen touch-control interaction technique fields, in particular to a kind of infrared laser touch sensible
System.
Background technique
General touch interaction needs just to can be carried out by corresponding touch screen hardware, can not expand in projection interaction,
And as the screen of touch screen increases, cost can also be significantly improved.In order to realize touch function on projection large screen, simultaneously
The cost of implementation for touching interaction is reduced, touch interaction can be realized on projection, non-tactile screen by researching and developing one kind, be used
Convenient touch sensing system has necessity.
Utility model content
It is required to solve general touch interaction using touch screen hardware realization, equipment cost is larger, needs special
Manufacture, the problem not being available on projection screen, general non-tactile screen provide a kind of infrared laser touch sensible system
System.
A kind of infrared laser touch sensing system, including Petting Area, the Petting Area be it is rectangular, on four angles of Petting Area
It is provided with infrared laser, is correspondingly arranged on infrared camera in front of Petting Area, the infrared camera is electrically connected with number
According to processing module.
Further, the opening of the infrared laser is perpendicular to Petting Area.
Further, the spacing of the infrared camera and Petting Area is 2-5m.
Further, the infrared laser is mono- wordline infrared laser of 850nm.
Further, the infrared camera is built-in with the infrared filter disc of 850nm.
Utility model has the advantages that
1, Petting Area can be arbitrary plane, not need special Touch Screen.
2, system is made of four infrared lasers, infrared camera and data processing unit, and arrangement is simply easy to implement.
3, manufacturing cost is low, versatile.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of infrared laser touch sensing system.
Attached drawing mark:
1- Petting Area, 2- infrared laser, 3- infrared camera, 4- data processing module, the infrared filter disc of 5-850nm.
Specific embodiment
It is required to solve general touch interaction using touch screen hardware realization, equipment cost is larger, needs special
Manufacture, the problem not being available on projection screen, general non-tactile screen provide a kind of infrared laser touch sensible system
System.
Keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, below in conjunction with the utility model
Attached drawing in embodiment, the technical solutions in the embodiments of the present invention are clearly and completely described, it is clear that described
Embodiment be the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art obtain without making creative work belong to this
The range of utility model protection.
As shown in Figure 1, the present embodiment provides a kind of infrared laser touch sensing system, including Petting Area 1, the Petting Area
1 is rectangular, and infrared laser 2 is provided on four angles of Petting Area 1, is correspondingly arranged on infrared camera 3 in front of Petting Area,
The infrared camera 3 is electrically connected with data processing module 4.In actual use, Petting Area 1 can be projection screen, metope,
Four infrared lasers 2 are arranged on four angle points of above-mentioned zone, and open infrared laser by the regions such as non-touch-control screen
2, the infrared light area of coverage can be formed on Petting Area 1, be used for touch sensible.When the contact of the objects such as finger, the teacher's pointer of people is infrared
The light area of coverage, infrared camera 3 can capture the hot spot of white shiny in trigger position, and the data that infrared camera 3 connects
The capture sense that touch coordinate point carries out touch location is analyzed and be converted to processing module 4 by obtaining infrared camera picture
It answers, realizes the effect of touch-control.Data processing module 4 can be the hardware such as computer, smart phone, run corresponding software.
The technical principle of the touch sensing system of the present embodiment are as follows: infrared camera 3 shoots corresponding infrared light region, data processing mould
Touch coordinate point is analyzed and be converted to the picture that block 4 obtains infrared camera 3, carries out the capture induction of touch location.
The opening of the infrared laser 2 is perpendicular to Petting Area 1.The beam emissions direction of infrared laser 2 and Petting Area 1
In parallel, it can avoid infrared light and generation interference reflected by Petting Area.
The spacing of the infrared camera 3 and Petting Area 1 is 2-5m.Infrared camera 3 and Petting Area 1 keep it is enough away from
From guarantee infrared camera 3 accurately can fully take entire Petting Area 1.
The infrared laser 2 is mono- wordline infrared laser of 850nm.
The infrared camera 3 is built-in with the infrared filter disc 5 of 850nm.850nm is the common wavelengths of infrared night vision monitoring, is taken the photograph
It is higher to the sensitivity of 850nm infrared light as head, it is correspondingly arranged 850nm infrared laser and infrared camera ensure that induction
Sensitivity.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions, i.e., it is all according to the made equivalent changes and modifications of the application range,
It should still belong in the utility model covering scope.
