Embodiment
Describe embodiments of the invention below in detail, the example of said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.
With reference to figure 1 and Fig. 2 the stereo-picture acquisition methods that the embodiment of the invention provides is described below.Stereo-picture acquisition methods of the present invention is handled to generate stereo-picture through portable terminal acquisition source image and to it.Wherein, portable terminal can be mobile phone, it will be appreciated by persons skilled in the art that certainly portable terminal also can have the mobile device of taking memory function for other.Be that example describes stereo-picture acquisition methods of the present invention below with the mobile phone.
As shown in Figure 1, the stereo-picture acquisition methods according to the embodiment of the invention comprises the steps:
S101: portable terminal is gathered first source images and second source images;
Move end in wait state when initial.Execution in step S1011, user press " 3D capture " key on the portable terminal; Execution in step S1012 starts two identical cameras of specification of installing on the portable terminal; Execution in step S1013 presses " shutter " key on the portable terminal; Execution in step S1014, through two cameras difference images acquired, wherein the camera lens of two cameras is parallel at a distance of 6-15 centimetre.Parameters such as the focusing of two cameras, zoom and sensitization all can be implemented control by same set of control circuit, thereby portable terminal can adopt identical focal length and organoleptic parameters to come images acquired.The shutter line of two cameras also connects, thereby when the user pressed " shutter " key on the portable terminal, two cameras were got image simultaneously, obtains visual angle difference and two identical width of cloth images of viewpoint, respectively as first source images and second source images.
S102: first source images that portable terminal is identical with acquisition time and second source images are organized right to form at least one picture group picture;
Execution in step S1021 stores first source images and second source images of above-mentioned acquisition in the memory device of portable terminal into.Wherein, memory device can safe digital SD card.In memory device, execution in step S1022 chooses the first identical source images of acquisition time and second source images and organizes rightly, makes first source images that acquisition time is identical and second source images corresponding one by one, and is out of order when avoiding screen display.One group of first source images after the correspondence and second source images is right as a picture group picture, thus it is right in memory device, to form at least one picture group picture.
S103: portable terminal generates synchronized signal and also is sent to the stereo-picture display unit, and according to synchronized signal drive first source images and second source images with the predeterminated frequency Alternation Display to form stereo-picture;
Portable terminal according to group in the step 102 to after first source images and second source images produce corresponding with it respectively first synchronized signal and second synchronized signal, and first synchronized signal and second synchronized signal are sent to the stereo-picture display unit.Wherein, first synchronized signal is used to drive the demonstration of first source images on the screen of portable terminal, and second synchronized signal is used to drive the demonstration of second source images on the screen of portable terminal.First source images and second source images under the control of each self-corresponding synchronized signal, on the screen of portable terminal with the predeterminated frequency Alternation Display, thereby form stereo-picture, i.e. 3D rendering.In one embodiment of the invention, predeterminated frequency persists frequency for surpassing human eye vision.Because human eye is when observing object, light signal successor cerebral nerve needed through one of short duration period.Effect at light finishes the disappearance immediately of after-vision image, and this phenomenon is called as persistence of vision phenomenon.It is the motion frequency that can produce the object of persistence of vision phenomenon that human eye vision persists frequency.Wherein, to persist frequency be 60Hz to human eye vision.Therefore, predeterminated frequency is not less than 60Hz.In one embodiment of the invention, predeterminated frequency can be 60Hz～80Hz.Certainly it will be appreciated by persons skilled in the art that predeterminated frequency can also be worth for other according to the hardware of portable terminal and the difference of environment for use.
S104: the reception of stereo-picture display unit also presents stereo-picture.
The stereo-picture display unit receives first synchronized signal and second synchronized signal from portable terminal.First of stereo-picture display unit appear end under the driving of first synchronized signal with the display synchronization of first source images, second of stereo-picture display unit presents end under the driving of second synchronized signal and the display synchronization of second source images.Wherein, first presents the left side that end is positioned at the stereo-picture display unit, and second presents the right side that end is positioned at the stereo-picture display unit.
Two present end and second through first of stereo-picture display unit respectively and appear to hold and watch stereo-picture, i.e. 3D rendering about the user.Wherein, user's left eye can be watched by first and present first source images that appears of end, and right eye can be watched by second and present second source images that end appears.Because first source images and second source images be the identical image of viewpoint for the visual angle is different, thus the user about two can under non-interfering situation, watch the visual angle difference and the identical image of viewpoint, it is the same that its effect is that image is taken the photograph in the eyes direct viewing.The user is down synthetic brain, can tell the difference of image longitudinal separation, thereby forms the sensation of 3D rendering.
In one embodiment of the invention, the stereo-picture display unit is 3D electronic liquid crystal glasses.First presents end is the left eyeglass of 3D electronic liquid crystal glasses, and second presents end is the right eyeglass of 3D electronic liquid crystal glasses.Certainly it will be appreciated by persons skilled in the art that the stereo-picture display unit also can have the device of watching the 3D rendering function for other.
Stereo-picture acquisition methods of the present invention because two cameras of portable terminal have poor location, can be gathered the visual angle pictures different, shows through the space comparison, and stereo-picture can the filtration fraction noise, obtains accurate more image.Because 3D rendering can present the sight of unprecedented directly perceived, gorgeous true 3D effect, makes the user experience 3D effect on the spot in person.And the portable terminal capture is more convenient, and the user can gather, watch stereo-picture through terminal in moving whenever and wherever possible, has quickness and high efficiency property.
