4) synthetic completion avi file such as last and sound, i.e. " portrait presenting " animation.
In the present embodiment, the 2nd) described scapegoat can be any nature person the step, and purpose is only got the rule of mouth, eye and headwork, to satisfy the needs of creative activity grid.Try to achieve approximate value according to observation and tentative calculation and confirm angle zeta, Fi, gama, to any one head portrait, the corner of taking to obtain some typical case is earlier asked other corner values again; The corner of typical case or be face the place ahead, the 30 ° of angles of turning left, left-hand rotation 45, the 90 ° of angles of turning left, turn right 30 ° of angles, right-hand rotation 45 or right-hand rotation 45s; Other corner values can be the angles between adjacent two angles in the aforementioned typical situation.
Logical thinking and relevant manufacturing technology details are described below in the portrait presenting:
Portrait appears vividly; To let photo deduce with the form of 3D and speak, sing (comprising countenance); When head portrait rotated, the approximation or the inaccuracy of approximate grid can reflect, and can carry out one or many and revise examination again; For example change color such as the change color of face's different parts, eyelashes, eyebrow, hair, beard etc. all will be made amendment according to different situations.Experiment showed, such after revising gradually near accurate result, its work can be accomplished through computer program, also can carry out manual operations through computer keyboard, its process is also uncomplicated, only needs once or revise several times just can meet the demands.Head is when rotating, and the variation of site coordinate is pressed following formula and handled.
For the original coordinates of any one site (like xp, yp, zp), when three angles become zeta, Fi, during gama, the coordinate of this point become (x, y z), are obtained by following formula:
1. eye motion equation
xx＝xp-centerx
yy＝yp-centery
zz＝zp-centerz
2. the eyebrow equation of motion
x1＝xx*cos(zeta)-zz*sin(zeta)
y1＝yy
z1＝xx*sin(zeta)+zz*cos(zeta)
3. the oral area equation of motion
x2＝x1
y2＝y1*cos(Fi)-zl*sin(Fi)
z2＝zl*sin(Fi)+z1*cos(Fi)
4. the nose equation of motion
x1＝x2*cos(gama)-y2*sin(gama)
y1＝x2*sin(gama)-y2*cos(gama)
z1＝z2
5. portrait head mass motion equation
x＝x1+centerx+movex
y＝yl+centery+movey
z＝z1+centerz+movez
In the above-mentioned equation of motion,
Certerx, centery, centerz are the true origin position,
X1, y1, z1, x2, y2, z2 is a variable,
Movex, movey, movez are the true origin displacement functions.
Angle zeta; Fi, the confirming of gama can only try to achieve approximate value according to observing with tentative calculation, and basic reason is any one head portrait; People's eye and computing machine all are difficult to tell the drift angle size, and the corner of taking to obtain earlier some typical case is usually asked other value again.
With reference to Fig. 1, Fig. 2 and Fig. 3, expression be only three angle zela of the ballad of 425 pictures, Fi, gama be with the angle situation of change curve that the picture number changes, and is that to have received and distributed wage adjustment whole amended.As for then all being made as zero before the adjustment.
Do grid by following formula, accomplish the unitary rotation of head basically, the adjustment of thin portion then need be done some on this basis in the eye of portrait, eyebrow, mouth, nose position, to obtain desirable effect.
Following a principle about the variation of the degree of lip-rounding, is exactly that everyone degree of lip-rounding of (say same words, sing same song) is identical, and that dehisces is big or small identical, the rule that this provides the shape of the mouth as one speaks to change for the portrait of making opening.
