Abstract
The invention belongs to the display technical field and provides a near-to-eye display system for blending virtual with real scenes. The system comprises a video interface, a near-to-eye display device, a first outdoor scene shoot device used for capturing front scenes and a splicing module. Video signals input by the video interface and foreground signals generated by the first outdoor scene shoot device are processed by the splicing module to produce picture signals to be input into the near-to-eye display device. According to the display system, the video signals input by the video interface and the foreground signals generated by the first outdoor scene shoot device are processed by the splicing module to produce picture signals to be input into the near-to-eye display device, and the near-to-eye display device displays spliced images, that are blended images of video images and foreground images, so that users can observe the blended images of virtual scenes (video images) and real scenes (foreground images) through the near-to-eye display system, that is the foreground images can be watched when the video images are observed, so that convenience is brought for the users.
Description
Technical field
The invention belongs to the display technique field, relate in particular to a kind of empty border and real border and merge near-eye display system.
Background technology
Along with development in science and technology, engendered near-eye display system, such as various near-to-eyes.Yet it is that vision signal shows that existing near-eye display system can only carry out empty border, gives the people with inconvenience.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of empty border and real border to merge near-eye display system, and it is extremely convenient to use.
The embodiment of the invention is achieved in that a kind of empty border and real border merge near-eye display system, comprises video interface, nearly eye display device, in order to obtain the first outdoor scene capturing apparatus and concatenation module of the place ahead scene; After concatenation module is processed, produce the picture signal of inputting described nearly eye display device from described the video interface vision signal of inputting and the foreground signal that is generated by described the first outdoor scene capturing apparatus.
After the embodiment of the invention will be processed with the foreground signal splicing that is generated by the first outdoor scene capturing apparatus from the vision signal of video interface input, produce the picture signal of the nearly eye of input display device, be the image that video image and foreground image merge altogether by the image behind this nearly eye display device display splicing, the user can watch empty border (video image) and real border (foreground image) to be total to the image that merges by this near-eye display system like this, namely when watching video image, can notice the place ahead scene, it is convenient to give the user.
Description of drawings
Fig. 1 is the structural representation that near-eye display system is merged in the empty border that provides of the embodiment of the invention and real border.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
After the embodiment of the invention will be processed with the foreground signal splicing that is generated by the first outdoor scene capturing apparatus from the vision signal of video interface input, produce the picture signal of the nearly eye of input display device, be the image that video image and foreground image merge altogether by the image behind this nearly eye display device display splicing, the user can watch empty border (video image) and real border (foreground image) to be total to the image that merges by this near-eye display system like this, namely when watching video image, can notice the place ahead scene, it is convenient to give the user.
Below in conjunction with specific embodiment realization of the present invention is described in detail.
As shown in Figure 1, the empty border of the embodiment of the invention and real border merge near-eye display system comprise video interface 1, nearly eye display device, in order to obtain the first outdoor scene capturing apparatus 11 and the concatenation module 2 of the place ahead scene, from the vision signal of described video interface 1 input and the foreground signal that is generated by described the first outdoor scene capturing apparatus 11 after concatenation module 2 is processed, producing the picture signal of the described nearly eye display device of input, can be the image that video image and foreground image merge altogether by the image behind the described nearly eye display device display splicing like this.In other words, the image that the user can watch empty border (video image) and real border (foreground image) to merge altogether by this near-eye display system namely when watching video image, can be noticed the place ahead scene, and it is convenient to give the user, especially during walking.
Said system also comprises obtaining the scape capturing apparatus 14 all round of the 3rd outdoor scene capturing apparatus 13 of the second outdoor scene capturing apparatus 12 of left scene, right-hand scene and rear scene, and the left scape signal that is generated by described the second outdoor scene capturing apparatus 12, the right scape signal that is generated by described the 3rd outdoor scene capturing apparatus 13, the scape capturing apparatus 14 background signal that generates and the foreground signal that is generated by described the first outdoor scene capturing apparatus 11 be simultaneously or timesharing input concatenation module 2 all round by described the.If described left scape signal, right scape signal, background signal and foreground signal are inputted concatenation module 2 simultaneously, the user can watch the panorama in its orientation, place, so need not to win this nearly eye display device, and namely the observable surroundings also need not rotary head, and is extremely convenient.If described left scape signal, right scape signal, background signal and foreground signal timesharing input concatenation module 2, the user can select arbitrary signal to amplify as required, gives special concern.
Nearly eye display device comprises display member, transfers to the waveguide member 4 of eyes side and the coupled apparatus that is optically coupled into waveguide member 45 that described display member is sent in order to the driving circuit 3 that drives described display member demonstration, the light that described display member is sent described in the embodiment of the invention.Particularly, described display member is by the little display screen 6 of LCOS, pointolite 7, the LCOS display member that even tabula rasa 8 and polarization beam apparatus 9 consist of; The light that described pointolite 7 sends is projected to described polarization beam apparatus 9 after even tabula rasa 8 disperses, form S light by described polarization beam apparatus 9 reflective polarizer; Described S light is projected to the little display screen 6 of LCOS, and part S light is transformed into the P light that carries image information through the little display screen 6 of described LCOS, behind the P light transmission polarization beam apparatus 9 of little display screen 6 reflections of described LCOS, is projected to described coupled apparatus 5.Certainly, described display member also can be DLP, TFT-LCD display member.
Usually, described P light through coupled apparatus 5 amplify, collimation is laggard enters waveguide member 4, transfers to the eyes side by described waveguide member 4; Wherein said pointolite 7 is LED, and described coupled apparatus 5 is the irradiation lens.In addition, the little display screen 6 of each outdoor scene capturing apparatus, video interface 1, concatenation module 2, driving circuit 3 and LCOS is integrated in same wiring board 10; Wherein said wiring board 10 in the form of a ring, in order to make the helmet-type near-to-eye.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
