The method comprises the following specific steps: generating two view videos, namely a left-view video and a right-view video, by a two-lens stereoscopic camera; performing virtual view generation by utilizing a depth map, and generating a 28-view video through view interpolation; processing the 28-view video into hogel data for storage; continuously writing in a hologram by a pulse holographic recording device according to a data stream, and updating image information by utilizing the next hogel data; and reading out the hologram in such a manner that light emitted from a colorful LED is incident at a Bragg angle, wherein a transmission holographic light path is adopted, so that a viewer can view a result of integrating a virtual environment with surrounding environments in the hologram writing-in process.
Description
Technical field
The present invention relates to a kind of augmented reality implementation method based on holographic technique
Background technology
Augmented reality the actual environment around the virtual environment of Practical computer teaching and user is combined together by photoelectric display technology, interaction technique, multiple sensors technology and computer graphical and multimedia technology, makes user be sure of that virtual environment is the part of true environment around it from sensory effects.The difficult point of augmented reality is the display device that virtual environment and true environment can be combined together.
Holographic technique utilizes interference and diffraction principle record and the technology of the recording and reconstruction of the real 3-D view of reconstructed object.The holographic technique first step utilizes principle of interference record object light-wave information, and this i.e. shooting process: subject forms the object beam of diffuse type under laser irradiation; Another part laser is as being mapped on holofilm with reference to light beam, produce with object beam superposition and interfere, the position phase of each point on object light wave and amplitude are converted to the intensity spatially changed, thus utilizes the contrast between interference fringe and interval to be recorded by the full detail of object light wave.The egative film that record interference fringe, after development, the handling procedure such as fixing, just becomes a hologram; Its second step utilizes diffraction principle reconstructed object light-wave information, and this is imaging process: hologram is under coherent laser illumination, and the full detail of reproducing object light, has real visual effect.Hologram is real 3-dimensional image, can merge with surrounding true environment well.
Calculating holography is be based upon on the basis of numerical calculation and contemporary optics.Traditional holography is the way with optics, makes hologram with interfering the method for record.Calculating holography is make hologram with computer coding, and it can comprehensively recording light wave amplitude and phase place, and noise is low, repeated high, can record the hologram of any even non-existent object, have obvious advantage than optical hologram.According to calculating requirement holographic and with great visual angle, the computed hologram (the free view-point Display Technique of relatively minimum 64 viewpoints, 28 viewpoints can meet hologram and require with great visual angle) of multiple views need be made.There is Synchronous camera between multiple views, image reconstruction quality, the problems such as multiple views compression bit rate in multiple views shooting.And because calculate holography to there is a large amount of complex operation, the object of display in real time can't be reached at present.Like this holographic technique is divided into two stage-hologram two-shot storage and hologram reconstruction, be kind of a real selection.Calculate the holographic a kind of implementation that can be used as Practical computer teaching virtual environment.
Photorefractive polymer has high-diffraction efficiency and recording sensitivity, and the life-span is long, can anti-light and electric injury, cost is low, can make large-area device, Reusability, the image stored can be preserved, and also can wipe within the several seconds and refresh, and meets the requirement of hologram three-dimensional display.Hologram adopts ps pulsed laser and ns pulsed laser source, 6ns pulse record holographic pixel (hogel) of an energy 200mJ.
By twin-lens stereo camera, produce two viewpoint videos in left and right; Utilize depth map to carry out virtual view generation, generate 28 viewpoint videos by viewpoint interpolation; 28 viewpoint videos are processed into hogel data and store; Pulse holography tape deck writes hologram continuously according to data flow, will use next hogel more new image information; The light that hologram color LED sends reads with Bragg angle incidence, and adopt the light path of transmission hologram, make in hologram ablation process, onlooker just can see the result of virtual environment and surroundings.
