摘 要：为研究时间和颜色对安检视觉搜索绩效的影响，运用E-prime软件设计视觉搜索试验，记录视觉搜索准确度和视觉搜索反应时间，最终利用E-Merge、Excel、EV、SPSS软件对试验结果进行统计、修正及分析。试验结果表明：时间对正确排斥的视觉搜索准确度的影响显著，时间对击中和正确排斥的视觉搜索时间影响显著，5 s和10 s、15 s的差异均显著，10 s和15 s的差异不显著。时间长度适当增加5～10 s，有利于安检准确度和效率的提升。颜色对击中视觉搜索准确度的影响显著，灰色图片较彩色图片击中个数多，即灰色有利于提高金属类违禁品刀具和剪刀的辨识准确度。颜色对正确排斥视觉搜索时间影响显著，灰色正确排斥所需时间较彩色的短。

Abstract： In order to study the effect of time and color on the visual search performance of security inspection， the visual search experiment designed with E-prime software to record the accuracy of the visual search judgement and visual search response time， finally， E-Merge， Excel， EV and SPSS software were used to count， revise and analyze the experimental results. The experimental results shown that time has the significant impact both on the accuracy of correct rejection search and the response time of hits and correct rejections. Especially， the significant difference between 5 s and other times such as 10 s and 15 s， but there was no much significant difference between the 10 s and 15s. It was conducive to the improvement of security accuracy and efficiency with the appropriate increase the length of the time that between 5 s～10 s. Color had a significant impact on the accuracy of visual search for hits inspections， and gray pictures had more hits and fewer missed inspections than color pictures which means gray is helpful to improve the accuracy of identification of metal contraband knives and scissors. Color had a significant effect on correct rejection， and it takes less time for gray to correct rejection than color.

視觉搜索是指人类通过眼睛的移动、注视和扫视等一系列活动来完成视觉信息的收集和判断，从而找到某个或某些目标物的过程[1]。视觉搜索在工作和生活中都有广泛应用，如工业检测[2]、军事勘察[3]、医学影像[4]、智能交通[5]等领域。铁路安检也是一个典型的视觉搜索作业，安检员根据形状和颜色等特征对X-ray行李图片快速搜索，发现可能存在的违禁物品。在违禁品搜索中可能出现漏检、虚报等情况，引致顾客抱怨并对公共安全造成威胁。因此，必须提高安检视觉搜索作业绩效。视觉搜索绩效主要取决于两方面指标：视觉搜索准确度和视觉搜索时间。……
