Description
Technical field
The present invention relates to small-sized projection and picture pick-up device field, relate in particular to and a kind ofly directly throw the 3D image and wear the small-sized audio-visual devices of formula by the nose that the 3D camera is taken and finger movement catches control to eyes.
Background technology
The display technique of personal electronic equipments is shown to the LCD character from initial light emitting diode signal and shows that having experienced displaying contents to the color liquid crystal demonstration again conforms to the principle of simplicity only to be transferred to complicated abundant evolution, and is at present high-end with the so-called retina display screen of American apple company.But take the retina display screen as example, its outstanding feature is that display resolution has surpassed the human eye resolution characteristic, yet this still can only regard the lifting of an amount as, the product that has like that the leap of matter from the character display screen to colorful display screen do not occur at present being similar in the demonstration field.See another kind of display technique---projection, its outstanding feature shows for realizing large scale, and just develops towards device miniaturization, portability and image high brightness and high definition again.Although but the shortcoming of projection is that the size of projector equipment image size producible with it own is not large, this makes its required overall space size very considerable to need to leave certain distance between projector and curtain during owing to normal imaging.And with regard to the imaging content, be that colorful display screen or projection are all take two dimensional image as main at present.But because 3-D view has than the more real sensory experience of two dimensional image, this is so that display screen and projector equipment provide the commercial city having an effect towards three-dimensional in the field separately.The 3D display technique of display screen aspect mainly contains two kinds of bore hole formula and spectacles, and the former advantage is the constraint of having broken away from glasses, but shortcoming is also to have a lot of deficiencies at aspects such as resolution, visible angle and visual ranges; And the latter's relative merits are roughly opposite with the former.Then mainly be traditional 3D projector+3D optometric technology aspect projection, its sensory experience is remarkably productive, but is mainly used at present 3D cinema, also popularizes to the personal user aspect.
The new breakthrough point is also attempted to find by some scientific ﹠ technical corporation between the old barrier of traditional display screen imaging and projection imaging.For example Sony corporation of Japan has been researched and developed the 3D display device of wear-type, owing to having adopted " double-display screen 3D technology ", its 3D display effect is very outstanding, but its product size is large and price is high.It is similar with glasses that the what is called of U.S. Google research and development " expansion reality " product google glass then does product design, and replace traditional eyeglass with a projection screen, by the electronic image of projection screen demonstration and the mode of natural outdoor scene combination have been brought brand-new experience to the user.But google glass major defect is not support the 3D imaging, experiences so that the user can not obtain the 3D rendering of approaching to reality; And what the control of equipment was used is Touch control key and the mode of rocking head, although also support voice control, its overall control mode is relatively stiff; Near-sighted user can't together use google glass and spectacles in addition, owing to there being the existence of screen to make its experience be similar to twenty-twenty people's wearing spectacles, comfort and imaging naturalness are not good enough simultaneously.
From human eye image-forming principle.No matter be the real scene image of external object generation or the electronic virtual picture of liquid crystal display or projection screen generation, the principle that brain obtains these image informations all is identical, namely thereby the light from image source stimulates the retina photosensory cell to make these image informations of brain perception through crystalline lens, and the image information that right and left eyes obtains is also incomplete same, and this is the key that produces stereo-picture.If this shows the light information of the light information of electronic image and real scene image project simultaneously on the eyes and electronic image also throw the different 3D light information of right and left eyes then electronic information and outdoor scene information will mix fully, bring the user fully real sensory experience.
With regard to control mode.The evolutions such as button, keyboard+mouse type and touch-screen have been experienced in the control of electronic equipment.The forefront is the motion capture control technology at present, the motion capture control technology that just is based on camera that the so-called somatic sensation television game machine such as the xbox360 game machine of Microsoft and the wii game machine of Nintendo uses.But the motion capture control technology is popularized in other personal electronic equipments at present in a large number, and at present computer control still adopts keyboard+mouse type mobile phone etc. then mainly take touch-screen as main.Motion capture control do not introduce other hardware, thereby hardware spending is less owing to mainly finishing based on camera on hardware.The trigger source of simultaneously motion capture control is human action, and the higher while of degree of intelligence also has excellent user to be experienced, and is very promising man-machine interaction means.The hardware foundation of at present motion capture is common camera, and include spatial depth information in the image information that the 3D camera obtains, this is that common camera is not available, then can obtain more accurately space action control effect if carry out motion capture control based on the 3D camera.
Present picture pick-up device is almost all based on the ordinary two dimensional camera, although the camera pixel has had sizable lifting, but because real world is three-dimensional, steric information important in the image information that common camera obtains lacks so that its application prospect is very limited.Now a lot of manufacturers all begin to research and develop the 3D camera, and the HTC company in Taiwan embeds the 3D camera at the Mobile phone of their research and development.Owing to only having 3D imaging and 3D shooting to grow up simultaneously the 3D technology is popularized in personal electronic equipments field large tracts of land, this has determined that the 3D camera will be the main flow equipment that following people obtain image.
