相关申请的交叉引用
本公开是以CN申请号为201710879776.9，申请日为2017年9月26日的申请为基础，并主张其优先权，该CN申请的公开内容在此作为整体引入本公开中。
技术领域
本公开涉及安检技术领域，特别是一种车辆安检系统、方法和控制器。
背景技术
相关技术中在车辆安检过程中存在两种成像方式，一种是X射线透视式成像，一种是X射线背散射式成像。
在利用透视成像进行车辆快速检查的过程中，由于需要用高剂量的X射线穿过车辆，因此会对驾驶室人员造成一定伤害。但是，若避开扫描驾驶室，仅高剂量扫描车身，则无法检查夹带在驾驶室的物品，降低检查的周密性。
背散射成像技术是使用X射线束照射物体，通过探测物体的背散射光子来成像的技术，具有辐射剂量低、对轻质材料敏感、图像直观等优点。但是背散射成像用的X射线穿透力较低，只能对被检物的表面浅层成像；穿透力比较弱，无法深入到物体内部去检查。

具体实施方式
下面通过附图和实施例，对本公开的技术方案做进一步的详细描述。
本公开的车辆安检系统的一些实施例的示意图如图1所示。车辆安检系统包括背散射探测器101、透射探测器102以及控制器103。背散射探测器101能够对车辆进行背散射探测。背散射探测器101保持常开状态，对待测车辆的各个部分均进行探测。背散射探测器101将背散射探测数据发送给控制器103。控制器103分析背散射探测数据，确定待测车辆的驾驶室已通过透射探测区域，继而开启透射探测器的射线发生 器，此时透射探测器102开始对透射探测区域内的车辆进行探测，由于车辆的驾驶室已通过了透射探测区域，因此避免了对车辆驾驶室的透射探测。
这样的车辆安检系统能够在对车辆进行背散射探测的基础上，根据背散射探测数据确定车辆驾驶室相对于透射探测区域的位置，当驾驶室离开透射探测区域后再开启透射探测器的射线发生器，从而能对全车进行背散射探测，避免对驾驶室进行透射探测，同时对车辆除驾驶室外的部分进行透射探测，在保证驾驶室人员安全的情况下提高安检效果。
在一些实施例中，控制器还能够根据透射探测数据确定已完成车辆的探测，进而关闭透射探测器，或仅关闭透射探测器的射线发生器，从而一方面能够减少X射线对周围人员的伤害，另一方面也能达到节能的效果。
在一些实施例中，控制器在得到透射探测数据和背散射探测数据后，利用背散射探测数据实现对车辆整体的安全检测，利用透射探测数据对车辆除驾驶室以外的区域进行安全检测，从而保证了驾驶室人员安全，也实现了对驾驶室的安检，保证了检查的周密性。
在一些实施例中，由于透射探测器和背散射探测器的部署位置相对固定，因此其探测区域也相对固定，可以基于背散射探测区域和透射探测区域的位置的差异，当获取车辆驾驶室在背散射探测区域中的位置后，确定驾驶室相对于透射探测区域的位置，进而实时确定车辆的驾驶室离开透射探测区域。在一些实施例中，控制器中可以预存有车辆驾驶室与车身之间的图像特点，如具有空隙、具有高度差、具有弧度或形状差异等中的一种或多种，通过图像识别确定驾驶室的位置。
这样的系统能够基于背散射探测数据确定车辆驾驶室相对于透射探测区域的位置，进而触发透射探测器的射线发生器工作，无需额外的传感器来触发，降低系统成本，也便于系统的部署。
在一些实施例中，背散射探测器的部署可以如图2所示，图中，车辆的行进方向为垂直于纸面向内或向外。背散射探测器204可以放置或嵌于地面；背散射探测器203可以置于顶棚或固定于顶架；背散射探测器201和202可以立在通道侧面。在一些实施例中，可以设置框架结构，框架结构的四周固定有背散射探测器，车辆从框架结构中穿过。多个角度的背散射探测数据可以分别处理，也可以合成后统一处理。
这样系统能够从上、下、左、右多个方向对车辆进行安全检查，减少了安检死角，提高了系统的可靠性。在一些实施例中，考虑到使用场合、成本、环境的要求，可以 适当减少探测器的数量。
在一些实施例中，透射探测区域32可以位于背散射探测区域31沿车辆行驶方向30的前方，如图3A所示，车辆驾驶室经过背散射探测区域31后再进入透射探测区域32。控制器可以根据背散射探测数据的变化情况确定车辆的速度，再根据背散射探测区域31和透射探测区域32的距离确定驾驶室在通过背散射探测区域31后到达透射探测区域32需要的时长t，控制器在确定车辆驾驶室经过背散射探测区域31后，延迟t后开启透射探测器的射线发生器。
这样的系统能够根据透射探测数据的探测数据确定车速和车辆位置，进而确定驾驶室离开透射探测区域的时刻，对开启射线发生器的效率要求较低，能够避免对车辆驾驶室以外的区域漏探测。
在一些实施例中，如图3B所示，透射探测区域32可以与背散射探测区域31相当。当控制器根据背散射探测数据确定车辆驾驶室经过背散射探测区域31后，即时开启透射探测器的射线发生器，从而无需检测车辆行驶速度，减少了控制器的运算量，降低了对控制器运算能力的要求，提高了控制效率。
在一些实施例中，如图3C所示，透射探测区域32可以位于背散射探测区域31沿车辆行驶方向30的后方，此时当控制器确定车辆驾驶室完全进入背散射探测区域31时，则驾驶室完全离开透射探测区域32，控制器开启透射探测器的射线发生器，从而无需检测车辆行驶速度，减少了控制器的运算量；同时避免车速较慢而射线发生器的开启速度较快的情况下产生对部分驾驶室的探测造成影响驾驶员的身体健康。
在一些实施例中，如图3D所示，射线发射器和接收器为多排阵列结构，背散射探测区域31和透射探测区域32可以有一定重叠或全部重叠。控制器可以确定透射探测区域32在背散射探测区域31中的位置，从而确定驾驶室离开透射探测区域32时在背散射探测区域31中位置，进而在驾驶室到达该位置时开启透射探测器的射线发生器。这样的系统占用的空间较小，便于设备部署。
本公开的车辆安检方法的一些实施例的示意图如图4所示。
在步骤401中，获取待测车辆的背散射探测数据。
在步骤402中，根据背散射探测数据确定待测车辆的驾驶室相对于透射探测区域的位置。在一些实施例中，由于透射探测器和背散射探测器的部署位置相对固定，因此其探测区域也相对固定，因此可以基于背散射探测区域和透射探测区域的位置的差异，当获取车辆驾驶室在背散射探测区域中的位置后，确定驾驶室相对于透射探测区 域的位置。
在步骤403中，判断驾驶室是否离开透射探测区域。若确定驾驶室离开透射探测区域，则执行步骤404；若确定驾驶室还未离开透射探测区域，则执行步骤402继续检测驾驶室相对于透射探测区域的位置。
在步骤404中，开启透射探测器的射线发生器。在一个实施例中，若透射探测器的其他部分默认处于关闭状态，则此时开启透射探测器的各个部分。
通过这样的方法，能够在对车辆进行背散射探测的基础上，根据背散射探测数据确定车辆驾驶室相对于透射探测区域的位置，当驾驶室离开透射探测区域后再开启透射探测器的射线发生器，从而能对全车进行背散射探测，避免对驾驶室进行透射探测，同时对车辆除驾驶室外的部分进行透射探测，在保证驾驶室人员安全的情况下提高安检效果。
在一些实施例中，当根据透射探测数据确定已完成车辆的探测时，关闭透射探测器，或仅关闭透射探测器的射线发生器，从而一方面能够减少X射线对周围人员的伤害，另一方面也能达到节能的效果。
在一些实施例中，当得到透射探测数据和背散射探测数据后，可以利用背散射探测数据实现对车辆整体的安全检测，利用透射探测数据对车辆除驾驶室以外的区域进行安全检测，得到安检结果，从而保证了驾驶室人员安全，也实现了对驾驶室的安检，保证了检查的周密性。在一些实施例中，当发现异常时还可以触发告警，以便工作人员及时发现异常。
本公开的车辆安检控制器的一些实施例的示意图。目标位置确定单元501能够基于背散射探测区域和透射探测区域的位置的差异，确定当车辆的驾驶室离开透射探测区域时驾驶室相对于背散射探测区域的位置，记为目标位置。驾驶室位置确定单元502能够获取车辆驾驶室在透射探测区域中的位置，并与目标位置进行比对。启动单元503能够在驾驶室位置确定单元502确定驾驶室到达目标位置时，开启透射探测器的射线发生器。
这样的控制器能够基于背散射探测数据确定车辆驾驶室相对于透射探测区域的位置，进而触发透射探测器的射线发生器工作，无需额外的传感器来触发，降低系统成本，也便于系统的部署。
