Camera Shot, Lighting And Background Planning For3D Mobile Animation Auto Generation System

Technology of full life cycle computer aided animation generation technology isa generation of animation technique based artificial intelligence proposed byacademician Ruqian Lu of Chinese Academy of Sciences, land in the last century90’s,the technology from the beginning of the limited natural language to write the story,generation to final animation, each step is completed under the assistance of computer.Automatic system for automatically generating technique is applied to the field ofmobile phone animation, according to the content of the message, automaticallygenerate the corresponding3D animation and with the original message to send to thereceiver.For a period of animation, camera shot directly determine the appreciationcontent for viewer, a good camera shot planning will be outstanding animationexpressive, so the viewer can clearly understand the content of the expression. Thelighting and background against the animation scene environment played an importantrole, as shown by the different time or different mood, make the animation to obtainbetter visual effect and more close to the content of the message.The goal of this paper is for3D mobile animation generation system, for the firsttime use the shot as a unit for planning and design research, according to addanimation scene objects and plot plan, for animation planning, planning camera shot,through quantitative calculation to achieve automatic generation of the shots of thecamera, and then montage the animation, rendering pictures material for planning,finally synthesis of video files. In addition to the camera shot planning, according tothe text extraction to the content of the animation, design the lighting and background,create a whole atmosphere.This work includes the following content:(1) Design and implementation of camera shot planningCamera shot planning is divided into qualitative planning and quantitativeplanning. In shot qualitative planning, designed the knowledge base, from the sceneand the plot planning related information, according to the shot qualitative planningstrategy, generate the plot planning instruction by selecting the correspondingshooting plan for every generates camera shot. Shot quantitative planning, studycamera quantitative calculation based on Maya, then automatic generation of camerashots to realize qualitative planning directives described.(2) Design and implementation of montage planningMontage planning is taken after the camera shot planning, according to themontage strategy, generate animation planning instruction. In rendering and animationmodule, according to the instructions for montage the shot frame render animated pictures, and finally synthetic video files.(3) Design and implementation of light background portfolio planningAccording to the animation scene type and short information extraction of timeand the theme of emotional, use of rules for lighting and background planning schemefind the most suitable planning, generate lighting and background in animation.In camera shot planning experiment, carry on the statistics of the test message isreceived from the system within two months, effective test120text messages, ofwhich81had camera shot planning, accounted for67.5%of the proportion of the total.In the81generation of animation rendering,35animation rendering of the shotseffect is good, that is each shots visual feeling good and each shot entirely withconsistent good planning;31animation rendering of the shots effect, that is each shotsvision feeling good but there may be a few problems, each animation paragraph shotand planning basic consistent, may appear a small amount of deviation; the other15animation rendering of the shots effect, that is the shots visual sense has obviousproblems or shooting and planning is not consistent, the main reason is the actualscene model information and plot planning information are different, resulting inquantitative planning error calculation.The results show that visual effect of animation by using camera shot planninghas improved significantly. Future work includes camera shot planning for morepeople and study the emotional expression in montage planning.
