Description
Technical field
The utility model relates to photographic goods, relates in particular to a kind of various dimensions stereo technology.
Background technology
Human stereoscopic vision key comes from the parallax of eyes.In essence, single the just two dimensional image of object that eyes are seen can be told its height and width, and can't discern its degree of depth.The mankind have two eyes, be horizontal, be about 63mm at interval, two when watching same object, because it is slightly different that residing angle has, the image that two eyes are seen has difference slightly, and brain combines this two width of cloth picture, form a kind of sensation that degree of depth distance is arranged, this process is exactly a stereoscopic vision.
The early stage stereo camera shooting and the development of imaging technique, be based on film as photosensitive material, stereocamera or stereo film camera are with high costs, shooting and stereopsis post-production need very superb specialized skills, thereby be difficult to popularize the more impossible occasion that is applied to real-time, interactives such as network shooting.Along with the rise of ordinary camera and video camera with popularize, withdraw from the market gradually based on the stereo photographic device of film.Development along with digital camera and IP Camera, occurred being fixed on the special mechanical pedestal with two digital cameras or camera, use comparatively complicated synchronization control circuit, obtain two images with certain parallax of object, be sent to after the computer, utilize specific application software to handle, the image that formation can be watched with stereoscopic vision.Though this method can obtain stereo-picture, it can't make the formal product that domestic consumer can use, and cost is relatively costly, thereby does not obtain business-like application.
In order people to be watched have stereo image, need respectively left-eye image is delivered to left eye and eye image is delivered to the device of right eye.Common technology has three classes at present: the one, and red/blue or green filter goggle, the 2nd, right and left eyes beam split viewing equipment, the 3rd, the staggered logical light liquid crystal glasses of right and left eyes.
Red/blue or green optical filtering is the most frequently used now stereo camera shooting and watches technology that the beholder only need can obtain goodish stereo perception with one pair of red/blue or green filter goggle that is dirt cheap.Concrete principle is by two images that diverse location is taken remove wherein redness and cyan respectively on same horizontal line with two earlier, and then both are combined forms an image.Wear the red glasses of cyan on one side when watching on one side, make left and right sides eyes can only see the image of object right and left eyes respectively, thereby in brain, produce stereoscopic visual effect.
PCB design claims PCB design, and it almost appears in the middle of each electronic equipment.All electronics of electronic equipment zero device all is set on the pcb board, realizes being electrically connected of each electronics zero device by pcb board.
Embedded System Design all need relate in the exploitation of many electronic equipments, and as inside wrist-watch, microwave oven, mobile phone, aircraft, communication satellite etc., each embedded system all is unique and highly special-purpose.Embedded system is to adopt C, C++, language such as Verilog HDL, VHDL as programming language, will be burnt in the various corresponding programmable chips by these language institute written program, realizes needed function by this programmable chip.
Disclose a kind of stereo-picture treatment system as prior art, be used in combination the graphics processing unit (central control unit) that a pair of video camera is taken the stereo camera shooting unit of stereo-picture and three-dimensional photographed images is handled.In this stereo camera shooting unit,, be provided with the nonvolatile memory that stores the camera properties data in inside for proofreading and correct the mutual characteristic deviation of a pair of video camera.And, connect such stereo camera shooting unit and stereo-picture processing unit by communication line, the correction data of storing in the nonvolatile memory can be transmitted by communication line thus and be outputed to the stereo-picture processing unit.In addition, by the stereoscopic image data of the shot by camera in the stereo camera shooting unit vision signal as analog form, output to the stereo-picture processing unit by communication line, in stereo-picture processing unit inside, carry out correction calculation according to the vision signal and the correction data of these analog forms of exporting from the stereo camera shooting unit.At present, exchange for making people carry out Internet video, various video frequency pick-up heads have been released, camera is a current class computer peripheral equipment that is widely used, it adopts a common lens to add that a CMOS/CCD transducer obtains the image of subject, handle the audio, video data that is encoded into MPEG or other standards through special DSP, be input to PC by USB interface, use some network interaction software (as MSN, ICQ, OICQ), people can share image resource each other at this machine or with interaction person on the Internet.But prior camera adopts single camera lens to add CMOS/CCD transducer construction system, can only obtain the two dimensional image that object has been lost depth information, and the Communicator can not watch the subject that stereoscopic vision is arranged, and lacks the experience of true interchange.So, design a kind of three-dimensional camera that can export stereo-picture in real time and necessitate.
