Description

A kind of act method for making of three-dimensional film image of encircling

Technical field

The present invention relates to the digital movie technology, specifically is that a kind of utilization computer three-dimensional animation is made software, makes the method for ring curtain three-dimensional film image.

Background technology

Three-dimensional (3D) animation has obtained using widely in many industries as emerging in recent years computer art.Three-dimensional animation is a virtual three dimensions that is provided with special animation software by computing machine, by building object model, model is placed on this three-dimensional stage,, gives the effect that each part is dynamic and strong texture obtains then from different angle light-illuminatings.When making three-dimensional animation, at first to create three-dimensional models such as object and background, allow these models in three dimensions, move then, remove the motion process of " shooting " model again by virtual " video camera " in the three-dimensional animation software, could generate lifelike digital movie picture at last.

The three-dimensional animation software of comparative maturity mainly contains MAYA, 3DS MAX, SoftImage 3D etc. at present.But it is (Rendering) mode of playing up on plane that these three-dimensional animation softwares only can provide the face of playing up, that is to say, when the picture of its generation only shows in the screen of plane, and when the orientation of plane screen is parallel with the face of playing up of playing up camera lens, could correctly restore defined scene relation in the three-dimensional animation software, obtain having an X-rayed correct, as not have distortion picture.

On the other hand, ring curtain three-dimensional film is the combination of three-dimensional film and Circamara, it is spliced into complete ring curtain picture with a plurality of projection units with picture in screen, allow annular screen spectators be surrounded and capture spectators' the visual field, in the film sight that picture by high-resolution can be immersed in spectators to have stereoeffect, add surround sound true to nature, for spectators bring vision shock effect strong as on the spot in person.The appearance of ring curtain three-dimensional film increases and has enriched the artistic expression of film, in many public places of entertainment, theme park and science popularization venue obtained using comparatively widely.

Traditional film shooting mode can not be taken the Circamara with stereoeffect.The development of Computerized three-dimensional technology provides possibility for making ring curtain three-dimensional film.Application number is that the patent document of CN 01107598.8 discloses a kind of method for making of digital rings curtain three-dimensional film on October 2nd, 2002, but this method exists defective and deficiency aspect following 4:

1, this patent claims " the set of cameras model is aimed at fillet zone on the face of cylinder, make the two video camera optical axis intersect at the central point of fillet " in the c item of claim 1.This patent stipulates that two optical axis intersect each other rather than is parallel to each other that two optical axis also are not orthogonal to the fillet of representing the screen position.Fig. 1 is the Figure of description of this patent, is the designed common parallax model of this patent, is positioned at the camera lens of playing up at two ends, the baseline left and right sides among Fig. 1, and its two optical axis is not parallel to each other, and is also not vertical with corresponding screen, but intersects each other in the mid point of the place ahead screen.

In three-dimensional software, the face of playing up of playing up camera lens always (is similar to real video camera or video camera perpendicular to boresight direction, its photographic film is total vertical with their shooting direction), since about two to play up the optical axis of camera lens not vertical with screen, so it is not their face of playing up promptly is not parallel to screen face, parallel to each other yet.Because two play up face and screen face is not parallel, the image mapped that renders to the screen after, the capital produces the perspective error, thereby can not reduce defined scenery perspective relation in the three-dimensional scenic exactly, its effect be equivalent to show with optical axis vertical direction on picture, but shown with the screen of optical axis off plumb on, this species diversity can be brought the error of perspective relation to spectators.

In addition, in fact, about the people two direction of visual lines is substantially parallel when watching the scenery in the place ahead, play up the eyes that camera lens comes the anthropomorphic dummy with the optical axis is uneven, do not meet the custom of watching of human eye yet.

2, this patent claims " base center is overlapped with center, the described face of cylinder " in the c item of claim 1.This patent regulation basic point promptly is on the axis on the face of cylinder, also is positioned on the mid point of face of cylinder short transverse simultaneously.

This patent is not suitable for basic point and is in the excentral situation in the face of cylinder.The position of basic point is that the best when watching Circamara corresponding to spectators is watched a little, watches Dian Chu in the best, and the defined scenery spatial relationship of three-dimensional scenic can access best reduction.And in fact, the position of basic point should not be only limited to the center on the face of cylinder, should be any point in the face of cylinder in theory, to adapt to the attend a banquet difference of position of spectators in the different arenas.Central point is far away more if spectators depart from the ring curtain, just can feel significantly more and have an X-rayed the wrong shear deformation of sum of errors.For example, as near spectators when basic point is arranged on center, the face of cylinder watching mute the ring curtain bottom, then in three-dimensional scenic manufacturing process, original idea is to want to allow certain scenery be in spectators' dead ahead, and the scenery that this moment, spectators saw by mute is positioned at oblique upper, and has wrong longitudinally shear deformation.Thisly watch orientation discrepancy and the wrong shear deformation that forms, also belong to the perspective error because of departing from basic point.

Under normal conditions, spectators can not be positioned near the central point of ring curtain because the light path that this position is blocked film projector possibly and throwed, spectators normally below central point with certain picture that angle is watched Circamara of looking up.Therefore, invent that a kind of the best is watched a little and the position of basic point arbitrarily appointed method be necessary, when guaranteeing basic point stray circle cylinder center, also can obtain perspective relation correct, not have the ring curtain three-dimensional film picture that is out of shape.

3, this patent claims " for each frame to be turned out movies; rich cylindrical center is rotary camera group and baseline flatly, respectively the three-dimensional scenic of its each fillet correspondence being played up (rendering) by two video camera models " in the d item of claim 1.For the same frame scene that will play up, this patent is only played up the camera lens gradation with one group and is played up whole image, in the operation that the gap is rotated camera lens of playing up of adjacent fillet.

This method is very loaded down with trivial details in practical operation, need reset the boresight direction of camera lens after having played up a certain fillet, makes this set of shots aim at adjacent fillet.With an embodiment in this patent document is example, if 6 sub-screens are arranged, each sub-screen has 8 fillets, it is inferior to be rotated operation 48 (6 * 8) so in the render process of every frame, and a complete film is often formed (the mute per second of standard is 24 frames) by tens thousand of frames even tens0000 frame pictures, its rotary manipulation amount is very huge, even the utilization computer program is realized these rotary manipulations, also be very difficult and unmanageable, even do not have operability.

4, this patent is stipulated " sub-screen quantity N " in the b item of claim 1; In the e item, claim " setting up three-dimensional model " with the true proportional face of cylinder of screen and N projection unit; In claim 3, claim " when screen is the face of cylinder, getting 6 sub-screens ".This patent is stipulated sub-screen number and is shown unit and count correspondent equal, all be N, and regulation N equals 6 forever again.

Yet sub-screen number need not and shows unit and count correspondent equal.In practical operation, projection unit number is mainly decided by the picture scope that projector covered, and when the picture scope of every group of projector projection on the ring curtain is big, only needs less projection unit just can cover whole ring act picture, otherwise, just need more projection unit.And sub-screen number should equal the picture packet count behind the fillet image mosaic, this packet count is relevant to the processing power of digital picture with computing machine, if the image-capable of computing machine is strong, can handle the image of bigger resolution, then spliced picture can divide into groups or not divide into groups less, otherwise will divide into groups more.Therefore, sub-screen number is determined by irrelevant each other condition that with projection unit number both do not have equal necessity.In addition, under the situation that the computer digital image processing power improves constantly, handle image, obviously do not make full use of the resource of computing machine, in operation and management, also seem loaded down with trivial details as will screen being divided into 6 sub-screens.

The present invention is by to common three-dimensional film analysis of technology, in conjunction with basic point can stray circle cylinder center requirement, summarize Fig. 2 and common parallax model shown in Figure 3.The present invention will make up with a plurality of common parallax models, have the face of cylinder rending model of parallax effect with formation.

In Fig. 2 and Fig. 3, prismatic surface 31 is the inscribed prism faces on the face of cylinder 30; Basic point 10 has departed from the axis 13 on the center 12 and the face of cylinder on the face of cylinder; Direction of observation 20 and reference plane 32 out of plumb, but vertical with baseline 11; A left side is played up the optical axis 25 and the right side of camera lens 21 and is played up the optical axis 26 of camera lens 22 all perpendicular to reference plane 32; Reference plane 32 is the effectively cone 23 and right effectively common cross-section of the cone 24 of a left side.

Among the present invention, allow all optical axis all the time perpendicular to the reference plane of correspondence, can not only guarantee that about every pair is played up two of camera lens to play up face all parallel with corresponding reference plane, avoid because of playing up the not parallel perspective error that forms of face and screen, and, allow the optical axis parallel mode in the left and right sides meet the actual custom of watching of human eye more.In addition, for making the axis of baseline energy stray circle cylinder, the present invention does not have cone shape default in the direct applying three-dimensional software, but allow all reference planes all become corresponding about the effective common cross-section of the cone, after this mode can not only adapt to the axis of basic point stray circle cylinder, requirement is set, can also guarantees that adjacent image is after splicing each effective cone is variform, picture is cross-over connection continuously, makes the vestige of the imperceptible splicing of spectators.

One embodiment of the present of invention such as Fig. 4 are to shown in Figure 6.

Step 101: as shown in Figure 4, in three-dimensional animation making software, creating one is the faces of cylinder 30 of 180 degree with the radius of real ring-like movie screen and highly proportional, radian.During concrete enforcement, the radian scope on the face of cylinder can be the arbitrary value between 0～360 degree.

Step 102: as shown in Figure 4, in the face of cylinder 30 that step 101 drew, create one by the individual rectangular surfaces of 9 (N=9) form in connect regular prism face 33, described prismatic surface 33 equates with the height on the described face of cylinder 30.During concrete enforcement, as long as it is enough narrow to form each rectangular surfaces of prismatic surface, quantity N is abundant, and its shape just can be near the face of cylinder, and prismatic surface at this moment just is equivalent to encircle the orientation of curtain.The regular prism face of forming by 9 shape identical rectangular faces that present embodiment is selected.

Step 103: as shown in Figure 4,, specify a basic point 10 in the inboard of described regular prism face 33.During concrete enforcement, the position of basic point can watch position a little to determine according to best in the real ring curtain arenas.The basic point 10 of present embodiment has departed from the axis 13 on the center 12 and the face of cylinder on the face of cylinder.

Step 104: as shown in Figure 4, on described regular prism face 33, select a rectangular surfaces as reference plane 32, the direction of 32 central points is the direction of observation 20 of reference plane 32 from basic point 10 to reference plane, cross basic point 10, create one with all vertical baseline 11 of the axis 13 on the direction of observation 20 and the face of cylinder, the length of baseline 11 determines that according to the interpupillary distance of human eye the mid point of baseline 11 overlaps with basic point 10 just.Among the present invention, when the axis of basic point stray circle cylinder, direction of observation is total vertical with corresponding reference plane, but baseline the direction of observation with corresponding is vertical all the time.

Step 105: as shown in Figure 5, at the two ends, the left and right sides of the resulting baseline 11 of step 104, create respectively that camera lens 21 is played up on a left side and camera lens 22 is played up on the right side, making two, to play up the optical axis 25 of camera lens all vertical with reference plane 32 with 26;

Step 106: as shown in Figure 5, the effective cone 23 in a left side and the right right effectively cone 24 of playing up camera lens 22 that camera lens 21 is played up on a left side are set respectively, making reference plane 32 is the common cross-section of two effective cones 23 and 24 just.Among the present invention, when the axis of basic point stray circle cylinder, the shape of all effective cones is not quite similar, need to be provided with seriatim according to the position of corresponding reference plane, rather than the direct cone shape of default setting in the applying three-dimensional software.

Step 107: select on the regular prism face 33 each face in all the other 8 rectangular surfaces successively as reference plane, arrive the method shown in the step 106 according to step 104 respectively, play up camera lens and set effective cone of respectively playing up camera lens to create altogether 2 * 9, as shown in Figure 6.When the axis 13 of basic point 10 stray circle cylinders, although the shape of effective cone of these 2 * 9 camera lenses is not quite similar, but every pair of cone all contains pairing reference plane just, and the optical axis of 18 camera lenses is all perpendicular to the reference plane of correspondence, two to play up the face of playing up of camera lens parallel in twos with reference plane about can not only guaranteeing like this, avoid having an X-rayed error, can also guarantee that the image that adjacent camera lens is played up can be spliced into complete picture.

Step 108: resulting 2 * 9 of step 106 is played up camera lens and done as a wholely, insert in the three-dimensional scenic to be played up,, all use described 2 * 9 to play up camera lens and play up, obtain 2 * 9 rendering images altogether for each frame of waiting to play up scene.The present invention is before playing up, and is pre-created 2 * N and plays up camera lens, and pre-set the boresight direction of all camera lenses and the effective cone, so the operation of positioning of rotating continually can avoid only playing up with pair of lens the time.

Step 109: for described 2 * 9 rendering images, playing up the image that camera lens plays up with 9 by a left side splices successively, to obtain cylindrical picture corresponding to spectators' left eye, simultaneously, playing up the image that camera lens plays up with 9 by the right side splices successively, to obtain cylindrical picture, so just obtained having the face of cylinder parallax effect, that correspond respectively to right and left eyes stereo-picture corresponding to spectators' right eye.The present invention plays up image that camera lens plays up and all right sides with all left sides and plays up the image that camera lens plays up and be spliced into an integral body respectively, rather than with screen 6 five equilibriums.In the present embodiment because it is identical to form the shape and size of 9 rectangular surfaces of regular prism face, so vertical pixel count of these 2 * 9 rendering images equate so that in this side up direct splicing.

Adopt and use the same method and step, all play up and splice for each frame of three-dimensional scenic to be played up, obtaining having the left eye cylindrical picture sequence and the right eye cylindrical picture sequence of continuous dynamic effect, and can finally be made into Circamara picture with stereoeffect.

The face of cylinder 30 in step 101 and the step 102 and prismatic surface 33 are only played up camera lens for setting correctly and effective cone is created, and be also inoperative during actual playing up.
