本发明涉及计算机技术领域，特别地涉及一种基于人脸识别技术的机场智慧航显方法和系统。
背景技术
目前，随着生活、工作的节奏与日俱增，为了节约时间，越来越多的人把乘坐飞机作为出行方式的首选。在人们享受飞机出行带来的便利的同时，不断增长的客流量也对机场的管理工作提出了挑战。大部分旅客通常会在机场航班信息显示屏(航显屏)设备处查看自己的航班信息，并根据机场内的指示路引找到自己的登机口。
目前的机场航显屏只能为旅客提供最基本的航班信息，旅客并不能很直观清晰的知道自己的登机口到底在机场内的什么位置、如有航班延误，也不清楚具体的航班到港时间。当旅客遇到上述问题时，通常会去机场内的咨询台进行询问，而这也正是现在大多数机场咨询台前都经常出现人满为患现象的主要原因。这种现象会大大增加机场工作人员的工作难度，同时也浪费了旅客自己的宝贵时间。
因此有必要提升机场航显的性能，使旅客能够更方便、更全面地获取在机场所需的与机场以及航班有关的信息。
发明内容
有鉴于此，本发明提供一种基于人脸识别技术的机场智慧航显方法和系统，有助于使旅客在机场的航显屏设备更方便、更全面地获取自己在机场所需的与机场以及航班有关的信息。

附图说明
附图用于更好地理解本发明，不构成对本发明的不当限定。其中：
图1是根据本发明实施方式的基于人脸识别技术的机场智慧航显系统的组成部分的示意图。
具体实施方式
以下结合附图对本发明的示范性实施方式做出说明，其中包括本发明实施方式的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施方式做出各种改变和修改，而不会背离本发明的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
图1是根据本发明实施方式的基于人脸识别技术的机场智慧航显系统的组成部分的示意图。如图1所示，机场智慧航显系统主要包括信息采集系统1、计算系统2、以及多个航显屏设备31、32、……、3N。以下分别对各部分的结构和功能加以说明。
信息采集系统1主要包括图像采集设备11、图像处理设备12、信息获取设备13。其中图像采集设备11可采用通常的摄像头装置，以采集旅客人脸图像。图像处理设备12可采用安装了相关功能软件的计算机，用以根据图像采集设备11采集的人脸图像得出人脸特征数据，可采用现有的各种人脸特征计算的算法来实现。信息获取设备13根据需要获取的信息的载体，可选择相应的一种或多种设备，例如可以是身份证阅读器，从而可以从居民身份证中获取身份信息，又如可以是条码扫描器，从旅客提供的其他证件上的条码中获取身份信息。
计算系统2是一个计算机系统，其中有航班信息系统21和人脸特征处理系统22，以及其他的计算系统。其中航班信息系统21按现有技术中的方式，在旅客购买机票时，保存该旅客的旅客信息及其搭乘航班的航班号。在本发明实施方式中，航班信息系统21还用于根据旅客信息确定该旅客的航班号，以及向航显屏设备发送该航班号对应的航班信息。人脸特征处理系统22用于保存旅客的人脸特征数据与该旅客的航班号之间的对应关系，以及根据该对应关系确定航显屏设备发来的人脸特征数据对应的航班号。另外计算系统2还保存了各航显屏设备的位置信息。
本发明实施方式中的航显屏设备除了具有触摸式显示屏，还具有图像采集装置，即摄像头，用来获取人脸图像；并且具有计算处理部件，能够进行图像处理等计算。这样，该航显屏设备除了具备其现有的功能之处，还能够在获取到人脸图像的情况下，从该人脸图像中获取查询信息的旅客的人脸特征数据然后发送给计算系统2，以及呈现计算系统2发来的航班信息，这是航显屏设备的功能之一，在计算系统2 的支持下，航显屏设备还可以向旅客提供更多的信息，具体在下文中加以体现。以下对本发明实施方式的基于人脸识别技术的机场智慧航显的方法进行说明。
在旅客到达机场之后应当进行安检。在旅客安检时，信息采集系统获取当前旅客的人脸特征数据和该旅客的旅客信息，然后发送给计算系统。计算系统根据该旅客信息确定该旅客的航班号，以及保存该旅客的人脸特征数据与该旅客的航班号之间的对应关系。这样，在旅客使用航显屏设备查询信息时，将面部靠近航显屏设备的摄像头，使航显屏设备获取到本人的人脸图像，再通过计算处理从而从该人脸图像中获取该旅客的人脸特征数据然后发送给计算系统。计算系统收到后，根据上述对应关系能够确定该人脸特征数据对应的航班号，然后将该航班号对应的航班信息发送给航显屏设备，这样航显屏设备可以在显示屏上呈现该航班信息，例如航班号、登机口号等。
在现实中，航显屏设备很可能采到不止一个人脸的图像，这是因为由于航显屏设备前可能有多名旅客等待查询信息，或者因为机场里人来人往，查询信息的旅客身边会有人经过，导致其面部图像也被航显屏设备的摄像头采集到。为了保证采集到的是查询信息的旅客的人脸图像，航显屏设备可以进行过滤。考虑到与其他旅客相比，查询的旅客的人脸的朝向是正对着摄像头，并且在摄像头前面停留的时间相对更长，所以航显屏设备在过滤处理时可以从接收到的多个人脸图像中，根据人脸在航显屏设备的图像采集装置前的停留时长和人脸朝向确定查询信息的旅客的人脸图像，再从该旅客的人脸图像中获取人脸特征数据。
航显屏设备可以向旅客提供更多的信息，旅客可以通过在触摸屏上操作来获取。例如可以获取机场的航站楼室内的地图，或者机场室外的地图。旅客还可以获取自己从当前位置前往自己将要搭乘的航班的登机口的路径。
为了在当前旅客使用当前航显屏设备进行查询时，向该旅客提供机场的航站楼室内的地图，计算系统在按照上文说明的方式确定了旅客的航班号之后，再确定该当前航显屏设备的地理位置，然后向航显屏设备发送机场的航站楼室内的地图，该航站楼室内的地图中标注有该航显屏设备的地理位置和当前旅客的航班号对应的航班的登机口的地理位置。最后由航显屏设备呈现机场的航站楼室内的地图。另外计算系统可采用现有的各种路径规划方法来确定从登机口到该航显屏设备的路径，将该路径标注在上述地图中。另外，除了提供上述的室内地图，计算系统还可以将机场的室外地图发送给航显屏设备。室外地图中可以标注机场地理位置、当前时刻机场附近上空飞行的航空器位置、机场附近的预设地点例如餐厅、商店的地理位置。
根据本发明实施方式的技术方案，通过将旅客的人脸特征与旅客的航班号进行关联，旅客无需手机输入信息，只需将面部对准航显屏设备上的摄像头，就能方便地在航显屏设备的屏幕上看到航班信息。除此之外，还可以得到从当前位置到登机口的路线，以及机场室内、室外的地图。
上述具体实施方式，并不构成对本发明保护范围的限制。本领域技术人员应该明白的是，取决于设计要求和其他因素，可以发生各种各样的修改、组合、子组合和替代。任何在本发明的精神和原则之内所作的修改、等同替换和改进等，均应包含在本发明保护范围之内。
