摘? 要： 由于現(xiàn)有的視覺傳達系統(tǒng)缺少對邊緣數(shù)據的識別，導致動畫人物的運動連續(xù)效果不好，為此提出一種虛擬現(xiàn)實環(huán)境下動畫人物圖形圖像視覺傳達系統(tǒng)創(chuàng)新設計。在硬件設計中，對渲染器的主板各項適配參數(shù)進行設計，優(yōu)化視覺傳達的體驗。在軟件設計中，通過引入Sobel邊緣算子，建立灰度函數(shù)求解梯度幅值，并選取閾值與其比較，完成動畫人物圖形圖像邊緣數(shù)據的識別與細化。對運動捕捉模塊進行設計，建立行為控制模型，生成并管理運動捕捉文件，完成系統(tǒng)的整體設計。設計模擬實驗，利用現(xiàn)有系統(tǒng)與設計系統(tǒng)分別構建動畫人物的運動，通過分析動畫人物運動抓取對比圖可知，所設計系統(tǒng)構建的動畫人物的運動動作比較連貫，四肢的位置在運動中的連續(xù)效果與真人的運動相似，驗證了設計系統(tǒng)的有效性。

Abstract： The existing visual communication system lacks of the recognition of edge data， which leads to the bad effect of motion continuity of animated characters. Therefore， an innovative design of graphic image visual communication system for animated character in the virtual reality environment is proposed. In the hardware design， the main board adaptation parameters of the renderer are designed to optimize the visual communication experience. In the software design， the grayscale function is established to solve the gradient amplitude with the introduction of Sobel edge operator， and the threshold is selected to compare with it， so as to complete the recognition and refinement of the edge data of the animated characters. The motion capture module is designed， the behavior control model is built to generate and manage motion capture files， and thus the overall design of system is completed. The simulation experiment is designed， from which the existing system and the designed system are used to construct the motion of the animated characters， respectively. It can be seen from the analysis of the motion capture comparison chart of the animation character that the motion movement of the animation character constructed by the designed system is consistent relatively， and the continuous effect of the position of the limbs in the movement is similar to that of the real person， the real person which verifies the effectiveness of the designed system.

卡通動畫逐漸成為一種重要的休閑娛樂方式和教育手段，在此趨勢下很多國家都將動漫產業(yè)作為支柱產業(yè)之一。我國動漫產業(yè)起步較晚，但發(fā)展迅速，在開發(fā)及研究新的動漫制作工具中取得了不菲的成績。在虛擬現(xiàn)實環(huán)境下，動畫人物圖形圖像視覺傳達也被應用在動漫創(chuàng)作中。為了更好體現(xiàn)出視覺傳達的整體效果，從原來的二維平面逐漸發(fā)展到當前的三維立體呈現(xiàn)[1]，這樣的轉變主要依靠視覺傳達系統(tǒng)實現(xiàn)。……
