Description
Technical field
The present invention relates to portable projection display enhancement implementing system, belong to the virtual reality technology field.
Background technology
Video perspective formula and optical perspective helmet display device have used for many years as traditional export technique of augmented reality system at present.It is strong that Helmet Mounted Display shows that as the fusion of virtual and real scene output device has a submergence sense, the advantage of high brightness.Yet they are faced with the deficiency on technical and the ergonomics.For example video perspective formula Helmet Mounted Display is a kind of enclosed display device.In case the outage user can't see extraneous scene; At some special dimension that need consider security, limited its usable range.In addition, video perspective formula Helmet Mounted Display substitutes the eye-observation world owing to adopted twin camera to take real scene, and video camera can not keep overlapping completely with user's viewpoint, thereby there is deviation in the video scene that the user is seen with true scene.For optical perspective helmet display device, because the optical lens group in optical transmission formula Helmet Mounted Display the place ahead allows to pass through simultaneously from the light in true and the virtual environment.The existence of this problem, the dummy object that make to show presents translucent state, thereby has destroyed the sense of reality that true scene and virtual scene merge mutually and blocked the depth information that offers people.In addition, because Helmet Mounted Display is generally heavy, the fast moving of image can cause the dizzy vomiting of user to wait malaise symptoms.
For these reasons, the augmented reality system based on Projection Display progressively shows technical advantage in recent years, becomes the research focus in virtual reality technology field.Utilize the forward projection instrument that the multimedia messages that computing machine generates is directly projected on the real scene based on the augmented reality system of Projection Display, need not the user and wear any display device.According to the different application purpose, can use single fixing projector.For increasing dirigibility and the drop shadow spread that shows, also projector can be installed on the whirligig.For the helmet showed, Projection Display can reach higher resolution, was suitable for the user and observed, and had improved the user to strengthening the adaptability and the comfort level of display environment.In addition, not only enlarged user's range of observation, can many people share, and can not make the user produce dizzy symptom based on the augmented reality system of Projection Display.Yet the existing greatest problem that exists based on the augmented reality system of projection is that projector need be installed in the fixed position, or needs the user to hand projector apparatus.In addition, and the projection angle of existing projector equipment can't make real-time adjustment according to user's demand.
Summary of the invention
Existing need be installed in the fixed position or need the user hand-held in order to solve based on projector in the augmented reality system technology of projection, and the projection angle problem that can not change, the present invention designs and has invented a kind of portable projection display enhancement implementing system.
Portable projection display enhancement implementing system of the present invention comprises video camera, projector, catoptron, angle locking structure, mirror motion control structure, mobile computing device.
Described video camera can adopt common CCD or cmos camera or camera, is used to gather the image of real scene, and offers mobile computing device.
Described projector is the purpose that reaches carry-on, can adopt micro projector, is used for the multimedia messages that computing machine generates is projected among the residing real scene of user, and it is hand-held to need not to be installed in fixed position and user.
Described catoptron is the common planar catoptron, does not influence the projection visual field in the time of satisfying horizontal projection, and the adjustable angle when turning back projection between catoptron and projector emergent pupil, angular setting scope are 0 to 50 degree, and can manually lock.
Described angle locking structure comprises two common screws, is used for fixing the position of catoptron.
Described mirror motion control structure is made of linear ramp guide rail and guidepost.The linear ramp guide rail can satisfy the push-and-pull campaign of catoptron, thereby realizes that catoptron can be recycled to the back side of projector under behaviour in service not, and guidepost is used to realize the spinfunction of mirror angle.
Described mobile computing device can adopt super portable PC, PDA or smart mobile phone etc. to can be used in equipment or the computing unit that the scene image of input is carried out video analysis and identification, generation multimedia messages.
The annexation of each ingredient of the present invention is: projector is connected by the VGA signal wire with mobile computing device, perhaps is integrated in the mobile computing device; Video camera is connected with mobile computing device by data line, perhaps is integrated in the mobile computing device; Catoptron is installed on the entrance pupil place of projector, catoptron picture frame both sides setting angle latch-up structure by the angle locking structure; The mirror motion control structure is installed on the side of projector, if projector is integrated in mobile computing device, then the mirror motion control structure is installed in the side of mobile computing device.
The course of work of portable projection display enhancement implementing system of the present invention is: start video camera, mobile computing device and projector.Video camera is taken the image of real scene, and image is transferred to mobile computing device.Mobile computing device carries out video analysis and identification to the scene image of input, according to the result of identification the multimedia show information of correspondence is inputed to projector.By the catoptron of adjusting projector entrance pupil place's installation and the angle between optical axis, multimedia messages can be projected to the required projected position of user.In case the user has determined the locus of the required demonstration of projector projection, the angle locking structure that can utilize catoptron picture frame both sides to install is carried out angle locking, thereby the projection that realizes real scene strengthens demonstration.System is under operating position not, and catoptron can be recycled to the projector back side by the linear ramp guide rail of mirror motion control structure.
Beneficial effect
Portable projection display enhancement implementing system of the present invention need not fixed installation or requires the user hand-held, can be worn on user's front with oneself, automatically discern scene by recognizer, and the multimedia messages Projection Display that computing equipment is produced is in real scene, strengthen sense organ understanding and the experience of user to scene, the image position that the projector projection goes out can be made manual adjustments according to user's demand.Volume of the present invention is small and exquisite, cost performance is high, its each ingredient can further be integrated into Projection Display and strengthen module, be widely used on the mobile devices such as mobile phone, digital camera, notebook, realize that the multimedia messages of real scene strengthens, expand the cognitive ability of user surrounding environment.
