附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例的一种自动收费***的结构示意图；
图2是本发明实施例的一种车载器的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参见图1，是本发明实施例的一种自动收费***的结构示意图，该***包括：收费通信装置101、车载器102，其中，所述收费通信装置101设置于计费公路入口处的承载架上，所述车载器102设置在待计费车辆的目标位置处，在该目标位置处，所述车载器102能够与所述收费通信装置101通信。在本发明实施例中，所述***还可以包括自动栏杆、费用显示器等设备。可以设置专门的ETC门架来放置收费通信装置101。收费通信装置101可以通过微 波或者射频等方式与设置在车辆上的车载器102进行通信。车载器102可以***ETC卡，并贴附在车辆的前挡风玻璃上，以便于更好地与收费通信装置101进行通信。
所述收费通信装置101，用于与所述车载器102通信，从所述车载器102中获取该车载器102所在的待计费车辆的车辆信息，以便于基于该车辆信息对所述待计费车辆进行计费。
所述车载器102，用于与所述收费通信装置101通信，向所述收费通信装置101上报由该车载器102记录的车辆信息。
所述车载器102，还用于在与所述收费通信装置101通信的同时或者之后的预设时间段内，获取所述待计费车辆行驶方向上的环境影像，并在所述环境影像上设置水印信息，存储设置了水印信息的环境影像，所述水印信息包括拍摄所述环境影像时所述待计费车辆的定位信息。所述与所述收费通信装置101通信之后的预设时间段内可以为一个很短的时间段，例如仅0.5秒的时间间隔，不能过长，过长了可能车辆已进入了高速公路，无法拍摄到入口收费站的环境。
环境影像可以大致拍摄到入口处的环境，在某些条件下，能够拍摄到入口的位置名称，例如经过深圳XX收费站时，会配置“XX”的字牌，因此，在本发明实施例中，可以单纯地基于拍摄的环境影像即可确定入口。为了确保入口信息的准确性，在本发明实施例中进一步地设置了水印信息，该水印信息包括定位信息，例如可以是GPS(Global Positioning System，全球定位***)位置坐标信息，基于环境影像进一步结合GPS位置坐标信息，能够确保得到准确的入口信息。
车载器102获取行驶方向上的环境影像的方式包括多种，在一个实施例中，所述***还可以包括：摄像装置103；所述车载器102通过有线或者无线连接方式与所述摄像装置103数据相连；所述车载器102，具体用于调用所述摄像装置103拍摄所述待计费车辆行驶方向上的环境影像。所述摄像装置103的镜头方向可以朝上，以便于拍摄到上述提及的例如“XX”收费站等字牌。
在一个实施例中，所述车载器102上设置有拍摄模块，所述车载器102具体是通过所述拍摄模块拍摄所述待计费车辆行驶方向上的环境影像。也就是说，在车载器102上处理配置有插ETC卡、读卡等功能外，还具有拍照功能。由于车载器102本身是贴合在前挡风玻璃的内侧上方，因此可以更为容易地拍 摄到诸如“XX”收费站等字牌。
本发明实施例中，所述方法还可以包括：GPS定位装置104，所述车载器102通过有线或者无线连接方式与所述GPS定位装置104数据相连；所述车载器102，具体用于从所述GPS定位装置104中获取经纬度坐标信息，并将所述经纬度坐标信息作为水印信息设置到拍摄得到的环境影像上。通过GPS定位装置104来获取位置坐标，进而方便后续能够进一步准确地确定入口信息。
在一个实施例中，所述车载器102，具体用于在基于所述GPS定位装置104检测到所述待计费车辆进入公路收费站的预设范围区域内时，拍摄所述待计费车辆行驶方向上的环境影像。也就是说，为了保证能够拍摄到诸如“XX”等表示入口位置的字牌，可以在检测到快到收费站时，就触发拍摄一段影像，由此可以确保能够拍摄到“XX”等收费站入口位置的字牌。收费站的坐标位置一般是固定的，因此，基于车载的GPS定位装置104等可以确定车辆是否靠近某个收费站入口，到达离该收费站入口的一定区域范围内，例如50m范围内。
在一个实施例中，所述车载器102通过已建立的WiFi热点与外部设备进行通信；所述车载器102，还用于在接收到外部设备的影像信息下载请求时，将存储的包括水印信息的环境影像传输给所述外部设备。
在一个实施例中，所述车载器102，具体用于在接收到影像信息下载请求时，对发起该影像信息下载请求的外部设备进行鉴权，在鉴权通过后，从内置的存储器中提取包括水印信息的环境影像，并将提取的包括水印信息的环境影像传输给所述外部设备。也就是说，车载器102只允许公路收费处的管理员设备等外部设备能够接入，这样可以放置入口信息被篡改。在本发明实施例的车载器102出厂时，可以设置某些特殊意义的字符，这些字符可以通过安全保密的通知方式通知给收费公路运营部门，以便于仅这些部门中的少部分工作人员能够基于特征意义的字符与车载器102建立连接，下载最近一次拍摄的待水印的影像。
车载器102可以循环存储拍摄到的环境影像，或者仅存储最近一次拍摄的环境影像。
本发明实施例中，车载器除了能够将在该车载器上***的ETC卡的相关信息上报给收费通信装置的功能，还能够触发对入口处的环境进行拍照的功 能，这两个功能相互独立的，当ETC卡出错无法确定入口信息时，可以快捷地读取ETC卡触发拍摄的入口视频信息，通过该水印来确定入口位置等信息。避免了ETC卡失效时确定入口信息效率低下的问题，节省了人力成本。
再请参见图2，是本发明实施例的一种车载器的结构示意图，所述车载器安装与待计费车辆的目标位置处，所述车载器包括：通信接口201、GPS定位模块202、摄像模块203、存储器204以及处理器205，其中：所述通信接口201，用于与收费通信装置进行通信，将存储在所述存储器204中的车辆信息发送给所述收费通信装置，以便于基于该车辆信息对所述待计费车辆进行计费；所述处理器205，用于在所述通信接口201与所述收费通信装置通信的同时或者之后的预设时间段内，调用所述摄像模块203拍摄所述待计费车辆行驶方向上的环境影像，并在所述环境影像上设置水印信息，将设置了水印信息的环境影像存储到所述存储器204中，所述水印信息包括拍摄所述环境影像时从所述GPS定位模块202中获取到的所述待计费车辆的定位信息。
所述存储器204可以包括易失性存储器(volatile memory)，例如随机存取存储器(random-access memory，RAM)；存储器204也可以包括非易失性存储器(non-volatile memory)，例如快闪存储器(flash memory)，硬盘(hard disk drive，HDD)或固态硬盘(solid-state drive，SSD)；存储器204还可以包括上述种类的存储器的组合。
所述处理器205可以是中央处理器(central processing unit，CPU)。所述处理器205还可以进一步包括硬件芯片。上述硬件芯片可以是专用集成电路(application-specific integrated circuit，ASIC)，可编程逻辑器件(programmable logic device，PLD)或其组合。上述PLD可以是复杂可编程逻辑器件(complex programmable logic device，CPLD)，现场可编程逻辑门阵列(field-programmable gate array，FPGA)，通用阵列逻辑(generic array logic，GAL)或其任意组合。
在一个实施例中，所述处理器205，具体用于在基于所述GPS定位模块202检测到所述待计费车辆进入公路收费站的预设范围区域内时，触发所述拍摄模块拍摄所述待计费车辆行驶方向上的环境影像。
在一个实施例中，所述处理器205，还用于在通过所述通信接口201接收到影像信息下载请求时，对发起该影像信息下载请求的外部设备进行鉴权，在 鉴权通过后，从所述存储器204中提取包括水印信息的环境影像，并将提取的包括水印信息的环境影像传输给所述外部设备。也就是说，车载器只允许公路收费处的管理员设备等外部设备能够接入，这样可以放置入口信息被篡改。在本发明实施例的车载器出厂时，可以设置某些特殊意义的字符，这些字符可以通过安全保密的通知方式通知给收费公路运营部门，以便于仅这些部门中的少部分工作人员能够基于特征意义的字符与车载器建立连接，下载最近一次拍摄的待水印的影像。车载器可以循环存储拍摄到的环境影像，或者仅存储最近一次拍摄的环境影像。
需要说明的是，本发明实施例中的车载器与上一实施例所描述的***中的车载器在功能实现相同，本发明实施例中的车载器以及其他结构、功能模块的具体实现可参考上一实施例中相关内容的描述，在此不赘述。
本发明实施例中，车载器除了能够将在该车载器上***的ETC卡的相关信息上报给收费通信装置的功能，还能够触发对入口处的环境进行拍照的功能，这两个功能相互独立的，当ETC卡出错无法确定入口信息时，可以快捷地读取ETC卡触发拍摄的入口视频信息，通过该水印来确定入口位置等信息。避免了ETC卡失效时确定入口信息效率低下的问题，节省了人力成本。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
