[0001] 本发明属于安检技术领域, 尤其涉及一种太赫兹安检方法及***。
背景技术
[0002] 太赫兹是频率在 0.1THz~10THz的电磁波, 其具有很强的穿透性, 能够轻易穿 透衣物, 目前用于机场、 火车站、 地铁站以及长途客运站等公共场所安全检测 的安检设备大多采用太赫兹安检设备。 太赫兹人体安检设备是通过扫描人体发 出的太赫兹波, 并将人体发出的太赫兹波经过处理转换后形成人体的二维太赫 兹"快照", 由于当人所穿衣物中隐藏有物品吋, 物品会吸收和阻拦太赫兹波的正 常轨迹, 使得"快照"中对应物品所在的位置和人体背景之间产生轻度对比, 从而 能够通过太赫兹"快照"探知到人体是否携带有物品, 然而现有的太赫兹人体安检 设备中一般是通过图像识别***自动对太赫兹"快照"进行识别, 然后将识别出的 人体图像和物品在人体图像中的位置以卡通图像的形式显示在安检终端的显示 屏上供安检人员査看, 而由于设备的分辨率、 图像处理及模式识别在物体特性 和尺寸上有一定的误差, 所以这种由图像识别***自动识别太赫兹"快照"的方式 在某种程度上可能存在有一定的漏检和错检的情况。
技术问题
[0003] 本发明实施例的目的在于提供一种太赫兹安检方法及***, 旨在解决上述由图 像识别***自动识别太赫兹 "快照 "的方式在某种程度上可能存在有一定的漏检和 错检的情况的问题。

本发明的实施方式
[0041] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实施例 , 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅仅用 以解释本发明, 并不用于限定本发明。
[0042] 图 1是本发明实施例提供的一种太赫兹安检方法的具体实现流程图。 参见图 1所 示, 本实施例提供的一种太赫兹安检方法, 可以包括以下步骤:
[0043] 在 S101中, 由监控端或客户端控制太赫兹扫描装置采集被测人体的太赫兹原始 图像, 并将所述太赫兹原始图像发送至中心服务器进行图像识别处理。
[0044] 在本实施例中, 由所述监控端的监控启动按钮或所述客户端的检测启动按钮触 发所述太赫兹扫描装置采集被测人体的太赫兹原始图像, 其中所述太赫兹原始 图像包括人体正面太赫兹人体图像和人体背面太赫兹原始图像。
[0045] 在 S102中, 所述中心服务器通过所述太赫兹图像识别出被测人体是否携带有物 品, 若有, 则在所述太赫兹原始图像中标记出物品所在位置, 生成带有标记的 太赫兹原始图像, 并将所述太赫兹原始图像和所述带有标记的太赫兹原始图像 发送至所述监控端。
[0046] 在本实施例中, 所述中心服务器可根据图像识别算法自动分别识别并标记中所 述人体正面太赫兹原始图像和所述人体背面太赫兹原始图像中物品的所在位置 , 然后将标记后的人体正面太赫兹原始图像、 标记后的人体背面太赫兹原始图 像、 标记前的人体正面太赫兹原始图像以及标记前的人体背面太赫兹原始图像 发送至监控端。
[0047] 在 S103中, 所述监控端根据所述带有标记的太赫兹原始图像在预先存储的人体 卡通图像上对应标记出物品的位置, 同吋将所述太赫兹原始图像和所述带有标 记的原始图像显示给监控人员, 使监控人员判断所述中心服务器是否出现识别 错误的情况。
[0048] 在本实施例中, 监控端在接收到中心服务器发送的标记前、 后的太赫兹原始图 像吋, 会根据标记后的太赫兹原始图像自动在预先存储的人体卡通图像上对应 标记处物品所在位置, 同吋还会将标记前、 后的太赫兹原始图像以及标记后的 人体卡通图像显示给监控端的监控人员, 使监控人员根据标记前、 后的太赫兹 原始图像分析是否有漏检和错检的情况, 其中, 太赫兹安检方法中标记前、 后 太赫兹原始图像以及带有标记的人体卡通图像的示意图具体可参见图 2所示。
[0049] 另外, 需要说明的是, 在本实施例中, 监控端还提供用于对显示屏中显示的太 赫兹原始图像进行连续浏览播放的播放按钮、 用于控制监控端停止连续浏览播 放太赫兹原始图像的暂停播放按钮、 用于査看上一帧太赫兹原始图像的上翻按 钮、 用于査看下一帧太赫兹原始图像的下翻按钮以及用于图像局部放大的功能 按钮。 监控端的监控人员可通过上述按钮根据控制监控端显示监控人员需要浏 览的太赫兹原始图像, 并可以对选中的太赫兹原始图像进行局部放大, 来辅助 监控人员更准确的判断是否出现漏检和错检的情况。
[0050] 在 S104中, 若有识别错误的情况, 则在所述监控端根据监控人员输入的指令更 改所述人体卡通图像上的标记, 并将更改后的人体卡通图像发送至安检人员的 客户端上进行显示, 使安检人员根据所述更改后的人体卡通图像判断被测人体 是否携带有物品。
[0051] 在本实施例中, 若监控人员发现有漏检或者错检的情况, 则可以手动更改人体 卡通图像上的用于标识物品在人体上位置的标记, 然后在更改完成后, 通过点 击监控端上的传送按钮, 将更改标记后的人体卡通图像传送至安检人员携带的 客户端进行显示, 这样安检人员既可以根据客户端上显示的人体卡通图像判断 出被检测人是否隐藏有携带物品。 [0052] 以上可以看出, 本实施例提供的一种人体太赫兹安检方法通过由监控端或客户 端控制太赫兹扫描装置采集被测人体的太赫兹原始图像, 并将所述太赫兹原始 图像发送至中心服务器进行图像识别处理; 所述中心服务器通过所述太赫兹图 像识别出被测人体是否携带有物品, 若有, 则在所述太赫兹原始图像中标记出 物品所在位置, 生成带有标记的太赫兹原始图像, 并将所述太赫兹原始图像和 所述带有标记的太赫兹原始图像发送至所述监控端; 所述监控端根据所述带有 标记的太赫兹原始图像在预先存储的人体卡通图像上对应标记出物品的位置, 同吋将所述太赫兹原始图像和所述带有标记的原始图像显示给监控人员, 使监 控人员判断所述中心服务器是否出现识别错误的情况; 若有识别错误的情况, 则在所述监控端根据监控人员输入的指令更改所述人体卡通图像上的标记, 并 将更改后的人体卡通图像发送至安检人员的客户端上进行显示, 使安检人员根 据所述更改后的人体卡通图像判断被测人体是否携带有物品, 从而能够提高安 检图像识别的准确率, 避免发生漏检和错检的情况。
[0053] 图 3是本发明另一实施例提供的一种太赫兹安检方法的具体实现流程图。 参见 图 3所示, 相对于上一实施例本实施例提供的太赫兹安检方案在由监控端或客户 端控制太赫兹扫描装置采集被测人体的太赫兹原始图像, 并将所述太赫兹原始 图像发送至中心服务器进行图像识别处理之前还包括:
[0054] 在 S300中, 将所述监控终端的安检模式设置为半自动安检模式, 所述安检模式 包括半自动安检模式和全自动安检模式。
[0055] 在本实施例中, 所述监控端的安检模式包括半自动安检模式和全自动安检模式 两种, 当监控人员选择半自动安检模式吋, 则进入本申请提供的太赫兹安检方 法的处理流程, 相反, 若监控人员选择全自动安检模式, 则进入中心服务器在 将标记前、 后的太赫兹原始图像发送至监控端后, 监控端在根据标记后的太赫 兹原始图像自动在预存的人体卡通图像上进行标记之后不再将标记后的人体卡 通图像显示给监控人员, 而是直接将标记后的人体卡通图像发送至客户端进行 显示。
[0056] 进一步的, 相对于上一实施例, 本实施例中在所述将更改后的人体卡通图像发 送至安检人员的客户端上进行显示, 使安检人员根据所述更改后的人体卡通图 像判断被测人体是否携带有物品之前还包括:
[0057] 在 S305中, 在所述监控端的显示屏上显示包含有各种危险物品图标的列表供监 控人员选择;
[0058] 在 S306中, 接收监控人员在所述列表中选择的危险物品图标, 并将监控人员选 择的危险物品图标导入所述卡通图像上对应的标记中去。
[0059] 在本实施例中, 所述危险品图标列表中至少包括铁器类的危险品图标和易燃物 类的危险品图像, 监控人员可根据标记后的太赫兹原始图像标记出的物品的大 小、 形状来识别危险品的种类, 然后选择与其对应的危险品图标添加到所述人 体卡通图像上对应的标记中去, 然后再所述人体卡通图像下发至所述客户端, 这样客户端的安检人员不仅可以根据所述人体卡通图像判处出被测人体是否隐 藏携带有危险物品, 而且还可以直接获取被测人携带的危险物品的种类, 以便 提前做好安全方法措施。
[0060] 进一步的, 相对于上一实施例, 本实施例提供的一种太赫兹安检方法还包括:
[0061] 当由监控端或客户端控制太赫兹扫描装置采集被测人体的太赫兹原始图像吋点 亮所述客户端上的扫描状态指示灯, 以提示安检人员当前正在对被检测人进行 扫描;
[0062] 当所述监控端将更改后的人体卡通图像发送至安检人员的客户端上进行显示之 后还包括:
[0063] 熄灭所述客户端上的扫描状态指示灯, 以提示安检人员当前所述被检测人扫描 结束。
[0064] 在本实施例中, 我们可以根据监控端处理进度来控制客户端的扫描指示灯的亮 灭, 当监控端启动吋, 控制客户端的扫描指示灯点亮, 提示安检人员正在扫描 被检测人的太赫兹原始图像, 当监控端将处理后的带有标记的人体卡通图像发 送至客户端后, 控制客户端的扫描指示灯熄灭, 提示安检人员被检测人扫描结 束, 这样当客户端的安检人员即可以通过客户端上扫描指示灯的状态获取监控 端的图像处理进度。
[0065] 需要说明的是, 本实施例中步骤 S301〜步骤 S304均与上一实施例的中实现方式 相同, 因此在此不再赘述。 [0066] 以上可以看出, 相对于上一实施例, 本实施例提供的一种太赫兹安检方法不仅 可以提高安检图像识别的准确率, 避免出现漏检和误检的情况, 而且还可以识 别出被测人体携带的危险物品的类型, 以使安检人员做好安全防范措施, 此外 还可以使安检人员实吋获取监控端的图像处理进度。
