Description

基于毫米波安检设备的查验方法和系统以及服务器
本申请要求于2020年6月28日提交的、申请号为202010600568.2的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及安检技术领域，具体地，涉及一种基于毫米波安检设备的查验方法和系统。
背景技术
目前，大部分机场安检仍以“金属探测门+手检”的方式为主。毫米波人体成像技术是目前全球安防领域的先进技术，已在美国、英国、荷兰、澳大利亚、日本等国机场用于旅客人身安检。该设备能够在不直接接触人体的情况下，有效检测出在衣物覆盖下藏匿于人体各部位的物品，特别是能够检测出非金属物品，并可以从图像上获取隐匿物品的形状、大小和位置等信息。此外，毫米波人体成像设备具有对人体无害、穿透力强的特点，其发射功率不及手机电磁波辐射的千分之一，能准确识别人体携带物品，有效提高检查的客观性、准确性、针对性，降低安检员的劳动强度，提升安检效率。
毫米波安检系统工作方式也通常采用类似“金属门+手检”的方式。目前利用包括罗德施瓦茨等毫米波安检仪产品进行安检的方法分为四个阶段：第一阶段(扫描阶段)，旅客在安检仪接受扫描，安检仪进行自动危险品识别(ATR)后，显示卡通图以及嫌疑物位置；第二阶段(选择手检站阶段)，旅客在安检仪接受扫描后，安检仪屏幕上直接显示已经配置好的手检站编号，由安检仪操作员手动选择分配手检站，旅客到选择的手检站位置处等候接受手检；第三阶段(判图阶段)，当有远程查验图像需求时，安检仪将扫描的图像以及ATR识别出的信息一起发送到连接的判图站，由判图员对扫描图像人工查验，然后提交判图结果(通过或报警)到安检仪；以及第四阶段(手检阶段)，安检仪将卡通图和嫌疑位置信息、以及判图结果发送到之前操作员选择的手检站，手检员根据图像和嫌疑物位置对旅客进行手检。
然而，当前的安检方法存在以下问题：所有业务数据分散存储在各个安检仪中，无法统一查询；安检仪对旅客进行扫描以后，需要安检仪操作员手动选择分派手检站；当 旅客流量增加后，无法动态增加手检人员和远程审图人员；以及当有多台安检仪同时工作(多个安检通道)时，无法对手检站和判图站进行复用。因此，需要用于解决上述问题的基于毫米波安检设备的查验方法和装置。

具体实施方式
以下，将参照附图来描述本公开的实施例。但是应该理解，这些描述只是示例性的，而并非要限制本公开的范围。此外，在以下说明中，省略了对公知结构和技术的描述，以避免不必要地混淆本公开的概念。
在此使用的术语仅仅是为了描述具体实施例，而并非意在限制本公开。这里使用的词语“一”、“一个(种)”和“该”等也应包括“多个”、“多种”的意思，除非上下文另外明确指出。此外，在此使用的术语“包括”、“包含”等表明了特征、步骤、操作和/或部件的存在，但是并不排除存在或添加一个或多个其他特征、步骤、操作或部件。

目前，毫米波安检系统工作方式也通常采用类似“金属门+手检”的方式(如图1和图2所示)，旅客在毫米波安检仪完成扫描，安检仪采用自动识别算法检测危险物品，然后以扫描原图或者卡通图(基于隐私考虑)的形式直接显示在安检仪屏幕上，旅客随后到固定的手检人员位置处进行手检。当在有隐私要求但又需要更进一步的查看原图时，采用一台固定的计算机放在与安检现场隔离的环境里，远程连接至设备端显示扫描图像。
图3示出了根据本公开的实施例的基于毫米波安检设备的查验系统的示意图。查验系统可以包括后台服务器系统310、安检通道320、远程判图室330和交换机系统340。后台服务系统310可以包括至少一个服务器，例如，服务器310 1、310 2和310 3。安检通道320可以包括至少一个安检仪(例如，安检仪320a和320b)和至少一个手检站(例如，手检站320 1、320 2、320 3和320 4)。远程判图室330可以包括至少一个判图站，例如判图站330 1、330 2和330 3。交换机系统340可以包括主交换机(例如，主交换机340 1)和多个从交换机(例如，从交换机340 2、340 3、340 4和340 5)。安检仪320a和320b、手检站320 1、320 2、320 3和320 4以及判图站330 1、330 2和330 3可以通过交换机系统340连接到后台服务系统310。应当注意的是，服务器、安检仪、判图站和交换机的数量不限于图中所示的数量，并且本领域技术人员可以根据实际需求进行设置。此外，还应当注意的是，查验系统中可以不存在手检站和判图站，也即是说，安检通道320中可以只包括安检仪，并且可以不存在远程判图室330。
