摘　　要：虚拟战场环境视景仿真属于感知仿真,其逼真度主要依据人的主观感受来判断,目前对于仿真的逼真性理论和视景仿真的评估方法的研究处于起步阶段,人工合成虚拟场景的逼真度还只是一个抽象的概念,缺乏理论依据和量化准则,其应用还停留在指导虚拟场景的构建和绘制的一个粗略的概念和原则的水平。对此,在对当前研究现状总结和分析的基础上,从人类视觉系统对信息感知和认知的角度出发,以视觉注意模型为基础,分析了影响视景仿真逼真度要素组成及相互关系,提出了主客观相结合的视景仿真逼真度综合评估框架,为视景仿真的逼真度评估提供了一种全新的视角。Visualization of battlefield environment belongs to the perceptive simulation, and its fidelity is mainly evaluated by the subjective feeling of human, as a result, the theory and evaluation method on it is not very mature, the fidelity of synthetic virtual battlefield environment is only an abstract concept, lacking of academic bases and measurement principle, which can only be used to instruct the construction of virtual environment. After a summary and analysis of correlative research actuality, a framework of evaluation method of visualization fidelity, which based on the visual attention mechanism and analysis of composition and relationship of influencing element, was proposed. This method deals with the fidelity evaluation in a view of process of visual perception and cognition of human visual system, and pioneers a new approach for evaluation of visualization.
