The animation method of personage's double provided by the invention, comprises the steps:
Steps A, draws the background picture that various scene does not go up at distant view, panorama two kinds of scapes respectively, is respectively used to the action picture mating different types.Contain various scenery in scene picture, in these two kinds of other backgrounds of scape, all scenes, scenery all in the middle and upper part of picture, and do not have scenery nearby, and lower middle portion is the splicing regions of personage's picture, and this region leaves some space.According to background object of reference principle physically, the shift action of personage in such distant view background can regard as and carry out in original place, and the transition frames picture of namely action can splice the same position on background picture.Fig. 1 (a) lists a kind of background picture of City scenarios, and Fig. 1 (b) lists the background picture of a kind of countryside scene.By this step, we can obtain the picture library of various background.
Step B, draws the transition frames material picture with the various body actions without head human body of different characteristic (namely possess various physical trait, dress various dress ornament) respectively, and defines the broadcasting order of each frame.Various dress ornaments in the present invention, the character moulding of various physical trait, cover common height, the various build such as short, fat, thin, and the various common dress ornament such as Western-style clothes, long gown.List one group of transition frames material picture corresponding when the job market white collar female body being installed with a kind of dress ornament does running action in Fig. 2, transition frames picture shows to play sequencing by numbering.All these pictures are all without head, its objective is that slot milling is to splice different head pictures.In picture, figuratum part is opaque, such as arm, clothes, health etc.; In picture, patternless part is all-transparent; Body action is divided into shift action, original place action two class usually.By this step, we can obtain the transition frames material picture library making various action without head health with various feature (comprise physiological characteristic and dress garment ornament).
Do not have certain sequencing relation between above-mentioned steps A, B, those skilled in that art can select random order to draw scene, without head human action picture as required.
Step C, measure on each transition frames picture of this picture group sheet of job market white collar running action, the scaling of head picture, head picture is at the splicing coordinate of health neck correspondence position, the angle of inclination of head picture on health neck (being defined as picture angle in table 3) and suitable angle lens (front, just face upward, positive overlooking surface, 3/4, side, side, the back side etc.), measure each group of head coordinate without head human action transition frames picture obtained, picture angle, angle lens and scaling data are as shown in Figure 3, as required, also some other correlation parameters can be measured to make splicing effect more precisely careful.
Step D, according to the transition frames picture of body action drawn in step B, that choose the angle lens suited the requirements, that there is required particular facial feature head picture, by head picture according to after scaling convergent-divergent, to measure the picture angle determined, be placed in the respective coordinates of action picture, be spliced into the personage's integral transition frame comprising head picture; One group that is so spliced into complete transition frames picture, is the animation of an action.
Because character facial also has expression action change, and when adopting traditional animation method for making to make animation, each different face, all need to draw separately the change that each transition frames with the overall face (comprising human face five-sense-organ) of various expression can realize personage's expression and action, this also needs to consume a large amount of manpower, and cost of manufacture is high.We are in this patent of invention of " animation method of human face expression action " (application number is CN2014104508126) of application in early stage, provide a kind of animation method of human face expression action, without the need to drawing the overall face and full face transition frames with each expression action, only need draw the picture library of limited face element, splice corresponding face picture according to coordinate, just can realize the animation of the various expression of various face and action.In the present invention, this facial expression animation method for making preferably combines in the present invention by we, and specifically, the manufacturing process of above-mentioned head picture comprises the steps:
Step D-1, be plotted in the various expression materials of each face under the angle of front on different characteristic face respectively, face material kind in the present invention not only comprises five kinds of face's human organs such as traditional " ear, eyebrow, eye, nose, mouths ", its essence covers in face to be had certain feature, can be used in distinguishing different face and face's element that may change along with expression and action, comprise hair, shape of face, eyebrow, eyes, nose, face, ear and face other characteristic sum that may exist modify.Above-mentioned expression comprises the slight change state of the contingent pleasure, anger, sorrow, happiness of people face, the expression such as dejected and some face's face.Because emphasis of the present invention is not in the change of countenance, therefore in Fig. 3, only list the shape of face 1 under normal expression and shape of face 2 each face material picture under the angle of front.
Step D-2, draws the face material of various feature respectively respectively at the different expression pictures of each common angle lens.Common angle lens comprise side, 3/4, side (i.e. the median surface of front and side), face upward the comparatively common camera lens visual angle in front (front of looking up), front of bowing (front overlooked) etc. below.List hair, shape of face, eyebrow, eyes, nose, face, ear, feature in the shape of face of two kinds of different characteristics under the angle of 3/4, side in Fig. 4, modify these face materials.
Step D-3, measure each face material in shape of face 1 and shape of face 2 except shape of face common angle lens (in this example for front, side, 3/4, side (i.e. the median surface of front and side), face upward front (front of looking up), front of bowing (front overlooked) below) under coordinate in shape of face.
Not there is between above-mentioned steps D-1, D-2 and D-3 certain sequencing relation, those skilled in that art can select that random order is drawn under each angle lens above-mentioned as required, the face material of different expression and surving coordinate.Above-mentioned each concrete angle lens listed should as restriction of the present invention yet, and person skilled can increase and decrease the quantity of angle lens or adjust angle, draws different face pictures as required.
Step D-4, suitable face element (hair, shape of face, eyebrow, eyes, nose, face, ear, feature, modification etc.) is chosen from the emotional state picture of each face element drawn all angles camera lens, replace on the coordinate of the correspondence of said features shape of face, namely can be spliced into the face of the different face feature of that comprise each face, that there is expression whole frame.Obviously, the face element in same facial expression animation all should belong to same type face, and when drafting one frame picture, the face element of different emotional state under same angle lens need be selected.In this example, we need to draw a certain transition frames in the human body animation of job market white collar under the angle of front, so namely the expression picture splicing of each face element in shape of face 1 under the angle of front is obtained the head picture of the job market white collar of each face feature with shape of face 1 in shape of face 1.
By the head picture completed by said method to measure the picture angle determined, be placed in the respective coordinates of action picture, be namely spliced into the personage's integral transition frame comprising head picture.In this example, for each frame of action picture in Fig. 2, make corresponding head picture and be placed in the corresponding coordinate of each frame action picture, namely obtaining the overall each transition frames of the personage containing head as shown in Figure 5.
Step e, in order, by the splicing of the transition frames of each action on the same background picture shown in Fig. 1 (a), obtains each frame picture as shown in Figure 6.When splicing, the background of distant view, can splice mobile, original place two class action; The background of panorama, can only splice original place action, and each transition frames splices on the coordinate of the same area of background, stays white middle lower zone when this region is background drafting.
Step F, each frame picture drawn in Continuous Play step e, forms the animation of the continuous print action of character physical.
In an above-mentioned animated actions, frame number is only a kind of example, and those skilled in that art can set the frame picture number play in an animated actions as required; In addition, the material picture of the background in each frame, health, head also can be chosen as required, can produce like this health from a certain background to another background, from the health of a certain role characteristic to another role characteristic, from a certain expression a certain angle lens to another angle lens another expression various Complex Animation processes.Although in the present invention, the countenance of personage is not done to change, and those skilled in that art should be clear, only need replace the face material picture of different emotional state in transition frames, can realize the expression synthesis between each frame.
Because patent submits picture restriction to, Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 6 are black and white picture, but the form of picture is not as restriction of the present invention, in real animation process, also can make color animation.
