The Design And Implementation Of The Complex Motion Planning In 3D Animation Auto-generation System Of The Cell Phone

Computer aided animation auto-generation is a research field that combining in the art and technology of many fields such as the animation technology, movie and TV production technology, artificial intelligence technology. 3D animation auto-generation system for SMS is a research direction in the field, with the purpose to put the 3D animation auto-generation technology applying in SMS in the way of receiving text message and converting to the visual 3D animation. At present, the system has achieved remarkable results, which has already constructed the whole system process that consists of text information extraction module, animation plot qualitative planning module, calculation module of animation quantitative, network rendering module. Solving the weakness of the system that human model only transform movement in simple motion planning, according to the characteristics of 3D animation what are fast pace, large margin and exaggerated rate, the paper has designed and implemented the path planning and interactive motion to adapt to the complex motion planning. Study on complex motion planning further enriches and improves the 3D animation auto-generation system for SMS with scientific research significance and application value.According to the demand of 3D animation auto-generation system for SMS on the high performance and rapid response to the request, the complex motion planning must focus on the ability of editing and processing motion data and the overall control and organization of sports, adapt human's sports to the environment, and has interactive activities with models. This is the key point of this research, and also a major challenge. Therefore, the main work of this paper includes:(1) Motion qualitative planningThis paper has established action knowledge base and design qualitative planning: designed the action figures ontology, and motion planning by the method based on action theme and template, according to the ontology library action attributes and relationships with plot planning; designed the action of acquisition data standardization processing to obtain the FBX file action process, and then built the action database. The descriptive language of qualitative planning results has been designed, and the results delivered to the quantitative calculation.(2) Motion quantitative calculationThis paper divides motion quantitative calculation into three parts: for interactive motion for characters and objects of calculation module, the paper has put forward 16 kinds of interactive motion model to describe the common sports in the animation scene design, designed a kinematics simulation method to construct ball parabola model and a model to realize the reciprocating motion of the ball and interactive, designed interactive movement design constraint method to achieve the figure and location of objects with constraint relation; for path planning module in mobile phone 3D automatic animation generation, based on comparing the common geometric programming algorithm and graph search algorithm, designed a method that constructs obstacle grid map, uses the Manhattan distance as the A* algorithm of heuristic function, and combines planning information on the map animation plot and scene information to realize path planning algorithm overall, and to achieve diversifying selection method for single path planning and multiply path planning; designed motion synthesis module based on Maya, according to the overall design of the complex motion planning to determine the module's main function including a motion attitude adjustment and motion connecting part, and then put forward the movement posture adjustment method based on Maya locator and the connection technology based on the Maya Trax editor.The paper carries on the availability, functionality and effect of planning in three aspects of the experiment: the availability of SMS statistical experiments with statistics of 370 messages half year from October in 2015, the rate of motion planning is more than 50%; functional experiments for interactive motion planning and path planning has verified the completeness and availability; due to subjective factors in planning effect, the experiment was carried out 20 text animation in form of the questionnaire with 10 mark system, analysis of the questionnaire results told that the complex motion planning enhances the 3D animation auto-generation system with an average 5 mark.
