基于视觉感受实验的目视航图评价

摘要

针对中国通用航空发展比较晚,目前还没形成一套完整目视航图符号的现状,在收集了多家航图制作单位目视航图的基础上,结合认知符号学及目视飞行对航图的要求,提出了目视航图及符号评价指标,通过视觉感受实验得到各评价指标的样本数据,最后用模糊评价方法给出综合评价值,探索目视航图符号的设计原则,为中国目视航图的发展提供理论依据.%A complete set of symbols is not formed for VFR chart in our country for the slow development of general aviation. On the basis of the VFR chart collected from lots of designers, evaluation index of VFR chart was defined with the Cognitive semiotics and the demand of chart for VFR. All the sample data of the evaluation index was get through the visual perception test. Finally, the value of comprehensive evaluation was given by Fuzzy evaluation. The designing principal of VFR chart symbols was summarized. It provided the theory basis for the development of VFR chart.
