A large amount of to popularize, increasing people are carried out taking pictures, are browsed the operation such as webpage using mobile devices such as mobile phone, flat boards, can be at any time
Everywhere the information in mobile terminal is projected on arbitrary plane, and interact on projection images formula operation become work as
Lower demand.
Mainly solved the above problems using virtual touch technology at present, the finger that receives according to photographic head or touch style of writing
The light for blocking when touching perspective plane and reflecting, it is determined that the positional information for touching, and according to this positional information control projection, realize text
The input of word and the content in mobile terminal device display screen is operated, so as to realize by virtual touch way to setting
It is standby to be operated.
China Patent Publication No. CN202815795U, on 03 20th, 2013 publication date, a kind of entitled " projection control
Device and electronic equipment " although utility model patent by integrated projection module in the electronic device, light generation module, sense
The hardware such as module are answered to realize the virtual touch-control to electronic equipment, but this projection control embedded in each electronic equipment
Mode, increased cost of goods manufactured, it is impossible to solve a projection arrangement and be suitable for polytype mobile terminal device
Technical problem.
Utility model content
In order to the information in mobile device is carried out Projection Display, realize the input of word and mobile terminal device is shown
Content in display screen is operated, and this utility model provides a kind of projection arrangement based on virtual touch technology.
To solve the above problems, the technical solution adopted in the utility model is：
A kind of projection arrangement based on virtual touch technology, including being connected respectively to optical filter the of a master controller
One photographic head, projection module, communication module, infrared transmitter and for catching mobile terminal device appearance images second are taken the photograph
As head.
Further, the infrared transmitter is a word infrared transmitter.
Further, a length of 808-810nm. of infrared waveses of the infrared transmitter transmitting
Further, the optical filter of first photographic head is the high filter mating plates of 800-850nm.
Further, the communication module is bluetooth module.
This utility model also include base and in bending or arc-shaped support；First photographic head, projection module
Rack-mount, projection module falls in the sight line of first photographic head in horizontal plane projection；The infrared transmitter
On base, and with plane-parallel which is located, the second camera separated with base, support.
In this utility model when finger touches projection of the projection module in interface surface, block and reflect infrared light
Line, and can there is hot spot at press points, the hot spot is received feeding master controller by photographic head and carries out binary image analysis, really
Determine the hot spot i.e. position of finger press points.Projection by touch projection module in interface surface can also realize the defeated of word
Enter and the content in mobile terminal device display screen is operated, so as to realize equipment being carried out by virtual touch way
Operation.This utility model receives the data such as image of mobile terminal and is incident upon in any plane and arbitrarily operates for user, realize and
Interaction between mobile device, this utility model are simple and convenient, cheap, are easy to the mobile terminal devices such as user's projection mobile phone
Interior information, it is easy to put into production.
Description of the drawings
Fig. 1 is the connection diagram of this utility model modules.
Fig. 2 is a kind of structure chart of embodiment of this utility model.
Fig. 3 is utility model works flow chart.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
A kind of projection arrangement based on virtual touch technology shown in Fig. 1, Fig. 2, including being connected respectively to a master controller 12
The first photographic head 10 with optical filter, projection module 11, communication module 13, infrared transmitter 15, also including being connected to
Master controller 12 is stated for catching the second camera 14 of 4 appearance images of mobile terminal device.
In order to realize projection of the present utility model and interactive function, also include installing each in a kind of preferably embodiment
The base 1 of individual module and in bending or arc-shaped support 2；First photographic head 10, projection module 11 are arranged on support 2
On, projection module 11 falls in the sight line of first photographic head 10 in horizontal plane projection；The infrared transmitter 15 is installed
On base 1, and with plane-parallel which is located, the second camera 14 separated with base 1, support 2.
The infrared transmitter 15 be a word infrared transmitter, a length of 808-810nm. of outer light wave of transmitting
First photographic head 10 has been arranged in pairs or groups the high saturating optical filter of a piece of 800-850nm, and optical filter has filtered the overwhelming majority
Visible ray, the infrared light of the infrared transmitter 15 can be received by the first photographic head 10 by the optical filter.
The principle of this utility model detection touch location is as follows：When finger or felt pen are pressed on a projection plane, meeting
There is hot spot at press points 3, the hot spot is received the feeding master controller 12 by the first photographic head 10 and carries out binary image
Analysis, determines the hot spot i.e. position of press points 3.
As shown in figure 3, the method that a kind of projection arrangement based on virtual touch technology of this utility model is operated include it is following
Step：
Step 101, the second camera 14 catch 4 image of outside mobile terminal device, determine that the mobile terminal sets
