Background
With the rapid development of network technology, in recent years, artificial intelligence teaching has been widely popularized on the network. At present, many teachers can complete on-line knowledge point explanation through an on-line teaching system with high proficiency. In the process of artificial intelligence teaching, it is a common means to deepen the perceptual knowledge of students on knowledge points by playing teaching animations. Traditional teaching animation production needs teaching and research teachers and cross-department cooperation of animation departments. The working process is as follows: the teaching and research teacher conceals the courseware originality and writes a script. And the animation department splits the script into a drawing part and an animation part and respectively completes the creation of the picture-inserting material. And (4) binding the teaching role and building the scene after the animator takes the picture-inserting material, and finally performing animation production. In the teaching role binding process: four limbs are manufactured by binding the children and the parents in AE, and the expression transformation adopts switching materials, so that a great deal of time is consumed for manufacturing a skeleton system. Meanwhile, in the scene building process, the background, the teaching role and the props in the scene need to be put together to adjust the size ratio, and the child-parent relationship and the hierarchical relationship are confirmed. During animation, it is necessary to make character actions and scene interactions by using rotation, scaling, displacement and some AE self-brought special effects. And editing and synthesizing after finishing the whole process, and adding sound effect and background music to finish the original video. In addition to the post-modification and adjustment, according to the conventional animation production process, a lot of time cost and labor cost for cross-department communication are needed for one set of two-minute animation. Therefore, how to develop a novel teaching animation can quickly realize teaching animation production, improve the working efficiency of teachers, save the time cost and the labor cost of cross-department cooperation, and is the direction of research needed by technicians in the field.
