安检视觉搜索绩效影响因素的关联规则分析
Analysis of Association Rules on Factors Affecting the Performance of Visual Search in Security Screening

为提高安检人员的视觉搜索绩效，降低漏检率，以16名机场安检人员和15名安检专业在校大学生为被试，基于Apriori算法，分析安检人员的经验水平、违禁品种类、遮盖程度、摆放角度、物品复杂程度以及物品凌乱程度等因素与安检绩效间的关联规则。结果表明：当安检人员缺乏经验、包内摆放的物品凌乱程度大且有其他物品遮盖违禁品时，他们最可能做出错误判断；在包内摆放的物品凌乱程度大、有其他物品遮盖违禁品的条件下，与错误判断构成的关联规则适用性最高；当包内摆放的物品凌乱程度小时，安检人员最可能做出正确判断；当安检人员有经验时，与正确判断构成的关联规则适用性最高。
In order to improve the visual search performance of security personnel and reduce the missed detection rate, 16 airport security personnel and 15 college students majoring in security inspection were selected as subjects. Based on Apriori algorithm, the association rules between the experience level of security personnel, the type of contraband, the degree of coverage, the angle of placement, the complexity of items and the degree of disorder of items and the performance of security inspection were analyzed. The results show that when security personnel are inexperienced, the items in the bag are messy and there are other items to cover the contraband, they are most likely to make wrong judgments; under the condition that the items placed in the package are messy and other items cover the contraband, the association rules formed with the wrong judgment have the highest applicability; when the items placed in the bag are in a low degree of disorder, the security personnel are most likely to make a correct judgment; when the security personnel have experience, the association rules formed with correct judgment have the highest applicability.
