Embodiment
Below in conjunction with drawings and the specific embodiments technical scheme of the present invention is described in further detail.
People wish when watching 3-D view sensation can with watch in kind the same, be spectators other sides that can observe object in the 3-D view synchronously of moving by spectators' self-position when watching 3-D view, this just need take into full account the reason that the human body stereo vision forms.The position of spectators' observing scene is called spectators' viewpoint, central point with two lines is as the criterion, the human body stereo vision be formed on the continuous variation that shows as spectators' viewpoint to a great extent, the variation of spectators' viewpoint can show as spectators' rotation or moving-head etc., the mobile of spectators' viewpoint can change the visual angle that spectators watch scenery, thereby make human eye can observe the not ipsilateral of scenery, two formed parallaxes of eyes of spectators formed when spectators changed by spectators' viewpoint the sensation of the distance of scenery and the depth of field.
The present invention with the residing space of spectators' viewpoint as view space, with the residing space of 3-D view as scene space, the accompanying drawings notion relevant at first with view space and scene space.
The view space coordinate diagram that shown in Figure 1 is is the center with original spectators' viewpoint, o ' point is original spectators' viewpoint, for making things convenient for actual mechanical process, usually with spectators' head as spectators' viewpoint, x ', y ', z ' are respectively viewpoint horizontal line, viewpoint perpendicular line and viewpoint depth line, form along original spectators' viewpoint respectively.Master reference point for showing with 3-D view shown in Figure 2 is the scene space coordinate diagram at center, the master reference point that the o point shows for 3-D view, be the original display center, x, y, z are respectively display horizontal line, show perpendicular line and show the depth line, are formed centrally in original display respectively.Sight line is the line of spectators' viewpoint and 3-D view display centre, and as shown in phantom in Figure 3, wherein the A point is spectators' viewpoint, and the B point is the display centre of 3-D view.
If scenery is a real material object, the then angle of spectators' observing scene or position difference, the demonstration of scenery in spectators' eye is also just different, if can be with the demonstration viewpoint of 3-D view according to the variation of spectators' viewpoint and to change in the plane shows, it be consistent with the sensation of observation material object so just can to make spectators observe the sensation of 3-D view.3-D view in showing as the plane with a square, if this square holding position is constant, spectators' viewpoint is done up and down on viewpoint horizontal line and the formed plane of viewpoint perpendicular line or during move left and right, if spectators can see the not ipsilateral of square, promptly reached the effect when spectators observe material object.
Fig. 4 is a scene space coordinate diagram, square among the figure is represented a 3-D view, be present in the scene space, make sensation that spectators watch this square and observe when in kind equally, then need this square to present its different side according to spectators' variation.If sight line that the display centre of square and spectators' viewpoint form and the demonstration depth line in the scene space coordinate diagram be angulation not, then square is shown in spectators' eye is X among Fig. 4, if the depth length between spectators' viewpoint and the square remains unchanged, allow spectators' viewpoint move left and right on viewpoint horizontal line and the formed plane of viewpoint perpendicular line, then square need be done corresponding angle variation to demonstrate its different side, promptly be in the square h and the d of same surface level among the figure with square X, therefore spectators can see the not ipsilateral of square left and right sides; In like manner, if allow spectators' viewpoint move up and down, then square need demonstrate its different side, promptly is in the square b and the f of same vertical plane among the figure with square X, and therefore spectators can see the not ipsilateral of square upper and lower sides; If spectators' viewpoint is carried out up and down and move left and right simultaneously, that then square needs corresponding demonstration is a, c, g or e, so that spectators can see corresponding variation.
In real life, generally be that the 3-D view of scene space and spectators' viewpoint of view space are in the variation simultaneously, this is more more complicated than the situation that only is the variation of spectators' viewpoint, need the viewed 3-D view of spectators to change synchronously in this case along with the change of viewing angle and distance, this variation can be understood as the demonstration viewpoint that requires the 3-D view in the scene space along with spectators' variation and does corresponding the variation, and guarantee to show viewpoint and spectators' viewpoint conllinear that it is consistent with the impression of observing actual scenery so just can to make spectators observe 3-D view.It is a kind of with the collaborative technical scheme of adjusting of spectators' viewpoint that shows in the scene space in viewpoint and the view space that the present invention promptly provides.That is to say that demonstration viewpoint in the scene space and the spectators' viewpoint in the view space are isolated no longer each other to be existed, but the demonstration viewpoint in the scene space can change accordingly according to the variation of the spectators' viewpoint in the view space.Technical scheme hereto, example is that demonstration viewpoint in the scene space overlaps with spectators' viewpoint in the view space the most intuitively, this is the collaborative a kind of special cases adjusted of above-mentioned two viewpoints.
Below technical scheme provided by the present invention is elaborated.
At first determine the position of view space, this detection method is an inductor that is used to detect the variation of spectators' viewpoint is installed near viewer's location, inductor detects the variation of spectators' viewpoint according to the sample frequency of setting, this variation is the variation of spectators' viewpoint location parameter in view space, and this location parameter is reported the controller that is attached thereto.Controller calculates the difference of spectators' viewpoint position parameter between double sampling, the difference that is calculated is the variable quantity of spectators' viewpoint, controller is adjusted the angles of display of three-dimensional scene according to this variable quantity, the demonstration viewpoint that makes three-dimensional scene and shows adjusted three-dimensional scene on sight line in real time in display device.
Controller according to the continuous variation of spectators' viewpoint change show viewpoint operating process referring to Fig. 5, its concrete operations step is as follows:
Step 501, controller are set the seizure frequency of inductor, inductor sends the location parameter of spectators' viewpoint to controller in real time, controller is determined the location parameter of original spectators' viewpoint according to the location parameter of the spectators' viewpoint that receives, and determine the location parameter of 3-D view original display viewpoint according to this location parameter, calculate three-dimensional scenic according to this location parameter, produce first three-dimensional scenic thus.
The location parameter of original spectators' viewpoint can be set in advance by controller, also can detect and obtain by inductor, two kinds of detection methods are specifically arranged, a kind of is maneuver first, and promptly controller starts the location parameter of first location parameter of spectators' viewpoint that the back captured as original spectators' viewpoint with inductor; Another kind is the method for on average determining, promptly controller starts the location parameter of the mean value of the spectators' viewpoint position parameter that is captured in a period of time of back as original spectators' viewpoint with inductor, and length during this period of time can preestablish.
According to different needs, the sight line sight line corresponding with spectators' viewpoint of view space of demonstration viewpoint correspondence that can scene space is set to overlap, and also can be set to a fixed angle.If wish that the demonstration of 3-D view is consistent with the effect of people's observing scene, then the sight line sight line corresponding with spectators' viewpoint of view space with the demonstration viewpoint correspondence of scene space is consistent, such as the z axle complete conllinear of the z ' axle that view space is set with scene space.Watch the effect of 3-D view and people normally to watch the visual angle of scenery that a deviation is arranged if wish, produce such as needs and to overlook or during effect such as stravismus, then can the coordinate figure of original spectators' viewpoint in the view space be increased a fixed value on the basis of original spectators' viewpoint position parameter that inductor obtains, perhaps certain eye coordinates axle be increased a fixing angle of inclination according to the angle of deflection.
Step 502, inductor produce the location parameter of spectators' viewpoint under the seizure frequency that controller is set, and send the location parameter that is produced to controller, controller calculates the difference of twice location parameter, this difference has promptly been represented the side-play amount of spectators' viewpoint positions, controller is adjusted the demonstration of three-dimensional scenic according to this difference, thereby guarantees that the demonstration of three-dimensional scenic and the variation of viewpoint keep synchronously.
The positional information of step 503, the present spectators' viewpoint of preservation, and judge whether to receive Stop message, if do not receive, then skip to step 502, otherwise, process ends.
In actual viewing effect, because the skew of spectators' head and health is limited, in order to strengthen display effect, can carry out processing and amplifying to the side-play amount of spectators' viewpoint position of collecting, according to the value after amplifying scene is adjusted then.Need preestablish the value of magnification of a side-play amount when carrying out this processing and amplifying, and this value of magnification and the side-play amount that calculates multiplied each other, with its product as new side-play amount, and adjust scene with this new side-play amount, the operating process of carrying out this processing and amplifying is referring to Fig. 6, its concrete operations step is increases some contents in the above-mentioned steps of Fig. 5 correspondence, in above-mentioned steps 501, set the value of magnification of a side-play amount, and in step 502, side-play amount and value of magnification are multiplied each other, the side-play amount that calculating makes new advances, and scene adjusted according to this new side-play amount.
The side-play amount of spectators' viewpoint position all comprises x, y, three directions of z in the above method, promptly considered the variation that spectators are all, when people observe things in fact, may only pay close attention to one or two direction, therefore in practical operation, can not all consider the variation of all directions.Such as, usually people just forwards, backwards or left and right sides transition position observe things, and transition position seldom up and down, therefore spectators' viewpoint change in location up and down can be ignored, for this situation, can when operation, only consider the change in location of spectators' viewpoint on x ' and z ' axle, and not consider the variation of y ' axle, be about to the value of spectators' viewpoint position parameter on y ' axle and remain unchanged.Its concrete operations step be in the step of Fig. 5 or Fig. 6 correspondence location parameter with original spectators' viewpoint in the value on the y ' axle as the fixed value of spectators' viewpoint position parameter on y ' axle, operational flowchart in this case is respectively referring to Fig. 7 and Fig. 8.
In general, the scenery that shows in the scene space is less than actual scenery, therefore a ratio value along the depth direction can be set as required, after adjusting the demonstration viewpoint of scene space, the demonstration viewpoint of scene space is further adjusted according to this ratio value according to spectators' viewpoint of view space.If desired 3-D view is amplified, then shorten the value of the demonstration viewpoint depth direction of scene space according to ratio value, otherwise, then increase the value of depth direction, can guarantee that thus the scenery in the scene space that spectators see has the authenticity of height.
Illustrate below and adopt the inventive method to carry out the actual effect that 3-D view shows.
Referring to Fig. 9, set x ' y ' z ' view space and xyz scene space according to original spectators' viewpoint, the z axle of scene space is set to overlap with the z ' axle of view space, pass the center of 1234 of three-dimensional rectangular parallelepipeds simultaneously, with 1,2,3,4,5,6 six drift angles representing the rectangular parallelepiped outside respectively.Spectators' viewpoint moves to the b point from a point on the x ' axle of x ' y ' z ' view space, when spectators' viewpoint during at a point, spectators can observed rectangular parallelepiped referring to Figure 10, when spectators' viewpoint begins from a point when the b point is mobile, rectangular parallelepiped will gradually change according to the variation of spectators' viewpoint, spectators' viewpoint move to rectangular parallelepiped 3465 parallel position and before, rectangular parallelepiped is shown as a rectangle that elongates slightly, 12 limits shorten gradually, elongate gradually on 34 limits, when spectators' viewpoint be moved beyond 3465 parallel position after, 3465 of rectangular parallelepiped begin to occur, and along with spectators' viewpoint moves progressively change greatly to what b was ordered, when spectators' viewpoint moved to the b point, shown three-dimensional rectangular parallelepiped image was referring to Figure 11.Along with the continuous variation of spectators' viewpoint, what occur in image shows will be the image of a gradual change from Figure 10 to Figure 11, and the speed of variation is consistent with the speed that spectators' viewpoint moves.As long as the sample frequency of used inductor and the refreshing frequency of display are enough high, the demonstration of this 3-D view will be level and smooth and coherent so.
When application the present invention carried out the 3-D view demonstration, the controller of used display device can be central processing unit (CPU), also can be image processor (GPU), can also be the combination of CPU and GPU; Used inductor need be connected with controller, can be sensor or video camera etc., can also be iris diagnostic device, and inductor can be installed on the display device, referring to Figure 12, also can be arranged on display device around, can also wear on one's body the user; Used display device can be LCD, flat-panel screens, plasma display, rear projection display and projector etc., can also be to make display device that annular or ball-screen projection show etc.Display device can have only one, also can be that a plurality of display device are spliced from different perspectives and got, if the situation of a plurality of display device, then need be provided with one and adjust the flow process that this display device 3-D view shows viewpoint, thereby guarantee that the display device that fixed angle is put can adjust its display frame synchronously according to the variation of spectators' viewpoint at each display device.
