中文摘要	虚拟伪装场景的真实度是使用其进行伪装效果评估的关键.运用心理物理学方法对虚拟伪装场景的真实度进行了评判,同时对不同评判者评判结果的分布和相关性进行了系统的分析和比较.用作评判样本的虚拟照片由三维软件Vue和Python语言创建,包含了不同的伪装场景类型.评判者有伪装研究生18人,应用化学本科生27人,临床医学本科生35人.研究结果表明:虚拟伪装场景的真实度可以通过基于照片媒介的心理物理学研究方法评判;3组评判者的评判结果均呈正态分布,对虚拟伪装场景的真实度判定具有普遍的一致性;不同人群评判最好和最差的样本存在明显的差异;基于Vue和Python的虚拟伪装场景效果真实,能够满足伪装效果评估的要求.
英文摘要	The virtual camouflage scene reality is the key of assessing camouflage effectiveness. The virtual camouflage scene reality was evaluated by psychophysical method, and the distribution and relativity of different judgers’ assessment results were analyzed and compared systematically. Among these judgers, there were 18 postgraduate students majoring in camouflage, 27 undergraduates majoring in chemistry and 35 undergraduates majoring in medicine. Photographs of yirtual camouflage scenes were synthesized by Vue and Python, containing woodland, desert, grassland, snow, water and so on. Sta-tistical analyses of the judgments lead to four main conclusions: the virtual camouflage scene reality can be evaluated by psychophysical method, using photographs as the media that represent the real camou-flage scene; the assessment results based on different judgers are distributed normally, and have an ac-ceptable level of coincidence; significant differences can be found between the best samples and the worst samples selected by different evaluating groups; the virtual camouflage scene based on Vue and Python is real enough for assessment of camouflage effectiveness.
