Abstract
The invention discloses a touch type projection image selection method, and belongs to the technical field of optical projection. The method includes the following steps: an image that needs projection is projected on a screen, and a camera performs real-time photographing processing on the image on the screen; film coating PE paper in front of a projector is touched, and the touched position of the film coating PE paper reflects high frequency rays; and the camera captures the high frequency rays, and the camera is driven to calculate and locate an emission position of the high frequency rays. Intelligent touch control of a projection screen is realized, and image content on a screen can be selected by touching, thereby realizing intelligent operation.
Description
Technical field
The present invention relates to optical projection technical field, relate to particularly the localization method of projection screen image.
Background technology
Optical projection apparatus plays an important role in the modern life, no matter in teaching process, or all will use projecting apparatus in even large-scale government's meetings and activities of daily company meeting etc.At present, development along with technology, the technology of projecting apparatus has obtained great development, function is also more and more complete, as Based Intelligent Control, networking etc., still, these projecting apparatus are all to utilize intelligent terminal to operate as computer or smart mobile phone etc. when playing, in conference process or in teaching process, if will select a certain content, identify or play, need to go to computer side or make assistant carry out play operation; Like this make meeting or teaching seem very inconvenient.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of projected image method for selecting that utilizes shade projection imaging, its objective is existing projector operation inconvenience, the intelligentized not problem of solving.
In order to solve above-mentioned technical problem, basic solution technical scheme of the present invention is:
A touch projected image method for selecting, comprises the steps:
To need the image projecting of projection on screen, video camera carries out real-time photography processing to the image on screen;
Plated film PE paper before touch projecting apparatus, this plated film PE paper back of the body touch place reflects high frequency light;
Video camera catches high frequency light, and drives this video camera to carry out compute location to the transmitting site of high frequency light.
In touch projected image method for selecting of the present invention, described plated film PE paper is affixed on a transparency glass plate.
In touch projected image method for selecting of the present invention, described video camera includes high frequency sensitive film and image processor, when described high frequency sensitive film senses high frequency light, drive image processor to process the image photographing, calculate high frequency light line reflection point with respect to the coordinate figure (X, Y) of image.
In touch projected image method for selecting of the present invention, described video camera includes four, and is arranged on the place ahead in four corners of described plated film PE paper.
The invention has the beneficial effects as follows:
Technical Design of the present invention has plated film PE paper and video camera, by touching plated film PE paper, produce high frequency light, video camera is caught the high frequency light that plated film PE paper emits, and take pictures, process touching the image of part according to high frequency light actuated camera, and obtain touching the position of part.The present invention, by such technology, realizes the Intelligent touch of projection screen and controls, and can just can select the picture material on screen by touching, and realizes intellectualized operation.
Accompanying drawing explanation
The process principle figure of Fig. 1 touch projected image method for selecting of the present invention;
The system schematic of the touch projected image method for selecting described in Fig. 2 Fig. 1.
Embodiment
Below with reference to accompanying drawing 1 and accompanying drawing 2, the present invention is described further, but should not limit the scope of the invention with this.
As shown in Figure 1, touch projected image method for selecting of the present invention comprises the following steps:
To need the image projecting of projection on screen, video camera carries out real-time photography processing to the image on screen;
Plated film PE paper before touch projecting apparatus, this plated film PE paper back of the body touch place reflects high frequency light;
Video camera catches high frequency light, and drives this video camera to carry out compute location to the transmitting site of high frequency light.
Contrast Fig. 2, projection equipment comprises screen 10, is positioned at the transparency glass plate 20 on screen 10 right sides, and the right flank of this transparency glass plate 20 attaches plated film PE paper 30, and the plated film side of plated film PE paper 30 is outward.In figure, find out, the right-hand video camera 40 that is provided with at four angles of described plated film PE paper 30, is projecting apparatus 50 on the right-hand of these cameras 40; Described plated film PE paper 30 comprises film plating layer and PE paper.
Wherein, described video camera 40 includes high frequency sensitive film and image processor, when described high frequency sensitive film senses high frequency light, drives image processor to process the image photographing, calculate high frequency light line reflection point with respect to the coordinate figure (X, Y) of image.
During concrete enforcement, projecting apparatus 50 will need the image of projection to project on screen 10 through plated film PE paper 30 and transparency glass plate 20, and wherein, described video camera 40 faces plated film PE paper and carries out real-time photography processing.When carrying out selected time the image projecting, touch the film plating layer on described plated film PE paper 30, touch after this film plating layer, meeting shading on screen, the film plating layer part being now touched also can form a shade position, now, film plating layer will send high frequency light, as ultraviolet light, this high frequency light can outwards reflect away, the camera lens of video camera 40 is provided with photosensitive layer, this photosensitive layer will detect high frequency light, in the moment that senses high frequency light, described video camera 40 will be taken pictures to the image on screen 10, during due to touch plated film PE paper 30, leave shade, therefore the photo taking also has a dash area.Then, described image processor will be processed comparison film, calculate the position of dash area in photo.In the processing procedure of photo, first on photo, set X-axis and Y-axis, then according to X-axis and the Y-axis set, calculate coordinate figure.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also change and revise above-mentioned execution mode.Therefore, the present invention is not limited to embodiment disclosed and described above, to modifications and changes more of the present invention, also should fall in the protection range of claim of the present invention.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the present invention.
