附图简要说明
此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本公开的实施例，并与说明书一起用于解释本公开的原理。
为了更清楚地说明本公开的技术方案，下面将对本公开所需要使用的附图作简单地介绍，显而易见地，对于本领域普通技术人员而言，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本公开一实施例提供的基于wifi6的交通信息获取方法的流程示意图；
图2为图1中步骤S110的流程示意图；
图3为本公开又一实施例提供的基于wifi6的交通信息获取方法的 又一流程示意图；以及
图4为本公开一实施例提供的基于wifi6的交通信息获取系统的示意图。
详述
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
相关技术中，导航地图一般是通过用户终端返回的定位系统数据来进行判断得到，例如，导航地图会获取用户手机或者车载导航上的实时位置信息来判断当前道路的道路通信情况。然而，该相关技术中的这种方式十分依赖道路上用户的数量，如果数量较少，很难及时形成有效的路况信息；如果某道路发生交通事故而影响了后方车辆的正常通行，而恰巧后方车辆较少，那么反映到导航地图上的路况信息很可能还是正常通行的情况，只有在道路上的汽车越堵越多时，才可能反映到导航地图上是拥堵是状况，使得其他用户不能及时获知该路况进而选择其他路线。另外，相关技术中导航地图提供的路况信息，一般只提供交通十分拥堵的信息，用户通过终端只能被动的接收该信息。
本公开提供了基于wifi6的交通信息获取方法及系统，本公开通过利用已有的交通道路设置，在交通道路上的图像采集器附件加装wifi6路由器，使得图像采集器可以将采集到的车辆信息通过wifi6路由器发送到服务器，服务器在接收到图像采集器上传的车辆信息时，会对该车辆信息及时处理，生成当前该道路上的路况信息，并将该路况信息发布到的导航地图上。这样用户在使用导航地图时，可以实时获取当 前道路前方的路况信息，进而及时选择出现线路。
在某些实施方案中，由于wifi6路由器可以覆盖更大的区域范围，并且可以容纳更大的通信通达及更大的通信传输速率，通过在一个地理位置设置一个wifi6路由器，并通过多个wifi6路由器可以覆盖例如一个城市的所有区域。在wifi6路由器的覆盖区域，可以满足多个图像采集器与服务器之间的通信。例如，服务器通过对图像采集器上传目标位置道路上的车辆信息的处理，可以判断该目标位置大陆上的当前交通情况，例如是否发生交通事故、堵车或者道路通畅等等，并将该目标道路的路况信息实时发布到导航地图上，满足用户出行的需要。并且由于wifi6具备更大的通信通道和传输速率，可以满足实时获取图像采集设备采集的图像信息并上传该图像信息到服务器及接受用户上传的路况信息的条件，保证数据的实时传输及能够避免数据传输的较大延迟现象。
在某些实施方案中，wifi6路由器还可以接收用户上传的临时道路信息，服务器在对该临时道路信息进行预处理后，例如出重、审核等，会将该处理后的临时道路信息一并与路况信息发布到导航地图软件中，可以为其他用户提供更为丰富和详细的路况信息，用户之间可以基于该路况信息进行互动。这样本公开通过主动上传自己了解的路况信息，还能与其他用户互动，可以有效克服相关技术中用户只能被动接收信息的问题。
在某些实施方案中，本公开提供了基于wifi6的交通信息获取方法，其中，wifi6路由器、图像采集器和服务器之间基于wifi6通信连接；其中，wifi6路由器的数量有多个，每个wifi6路由器覆盖预设范围内的地理区域，在一个wifi6路由器为中心的预设范围内，设置有多个图像采集器，如图1所示，该方法可以包括如下步骤：
步骤S110，图像采集器获取道路上的车辆信息，并向wifi6路由器发送车辆信息；
步骤S120，wifi6路由器接收图像采集器发送的车辆信息，并向服 务器发送车辆信息；以及
步骤S130，服务器接收wifi6路由器发送的车辆信息，并将车辆信息生成路况信息，以及将路况信息发布到预设导航地图软件中，以便通过预设导航地图软件在终端上展示路况信息。
在某些实施方案中，图像采集器设置于道路上方，车辆信息包括车辆图像，每个图像采集器配置为采集同一车流方向的车辆图像。
在某些实施方案中，目前很多道路上都设置有摄像头，通过抓拍来判断是否有交通违规的车辆，本公开可以利用已有的交通道路设施，例如在交通路口或者通行道路上安装摄像头的设施上部署wifi6路由器和图像采集器，或者利用已有的摄像头作为该图像采集器等。由于一个wifi6路由器可以覆盖一定的范围，那么在一定的区域范围，例如一个城市等，可以通过部署多个wifi6路由器来实现全覆盖，形成如蜂窝网状的覆盖形式。这样在一个wifi6路由器的覆盖范围内，可以有多个图像采集器通过wifi6路由器与服务器进行通信。
在某些实施方案中，图像采集器可以设置在道路的上方，并且一个图像采集器可以采集同一车流方向的车辆信息，通过图像采集器将获取到当前道路位置上的车辆信息，通过wifi6路由器及时发送到服务器，以便通过服务器进行实时处理。
在某些实施方案中，由于wifi6通信技术可以提供更快的速度、更大的覆盖面积、更好的安全性和更低时延等性能；本公开通过采用wifi6路由器实现图像采集器与服务器之间的通信，可以大大降低通信时延，便于用户更快获取路况信息，同时，通过采用wifi6路由器可以通过较少的无线设备实现更大的覆盖范围。
在某些实施方案中，通过服务器对接收到的车辆信息进行处理，例如对车辆信息中的车辆图像进行分析判断，可以生成当前道路的路况信息，例如拥堵、交通事故或者通行通畅等。并将该路况信息发布到预设导航地图软件中，方便用户通过该导航地图软件及时获取当前路段的交通情况。
在某些实施方案中，服务器在检测到该车辆图像中有预设标识时，并确定该标识在图像中的位置，可以判断是否有交通事故发生。例如，服务器检测到车辆图像中出现了包含交警服饰的预设标识，并且该预设标识在连续的几张车辆图像中处于道路的车辆附近，并且该道路是处于拥堵状态，那么可以大概率判定当前是发生了交通事故导致的车辆拥堵。或者，服务器在检测到车辆图像中，两辆或者多辆车发生了碰撞(车之间接触在一起)，很可能发生了交通事故，可以做出当前道路发生了交通事故的路况信息。
本公开提供的基于wifi6的交通信息获取方法，图像采集器通过将获取到的车辆信息通过wifi6路由器发送给服务器，服务器在接收到该车辆信息时，通过对该车辆信息的及时分析处理，并将生成的路况信息发布到预设导航地图软件中，便于用户及时的获取相关道路的交通状况。由于本公开采用wifi6技术，可以保证图像采集器在低延时的情况通过wifi6路由器将获取到的车辆信息发送到服务器；并且本公开实施例并不依赖用户终端返回的位置信息来生成路况信息，可以通过部署在道路上的图像采集器全天候实时获取车辆信息，并通过服务器对车辆信息的处理，生成路况信息并发布到预设导航地图软件中，方便用户能够实时掌握相关道路上的通行情况。
为了提高图像采集器的信息采集效率，在本公开提供的又一实施例中，如图2所示，步骤S110可以包括以下步骤：
步骤S111，图像采集器按照预设采集频率采集当前道路上的车辆图像，以便将采集到的上述车辆图像通过wifi6路由器发送给服务器；以及
步骤S112，图像采集器接收服务器通过述wifi6路由器发送的采集频率调控信息，并根据采集频率调控信息调节当前道路上对车辆图像的采集频率。
在某些实施方案中，图像采集器可以根据需要，按照预设采集频率来采集道路上的车辆图像，例如实时采集，还可以周期性的采集等 方式进行采集；或者图像采集器还可以根据当前时刻选择对应的预设采集频率进行采集，例如，将一天中的24h划分为多个时段，不同的时段对应不同的采集频率，示例性的，由于白天和傍晚的车流量大，其对应的采集频率可以较高，深夜与凌晨的车辆较少，可以降低对应的采集频率等等。又或者，在上下班高峰期可以提高采集频率等。
在某些实施方案中，图像采集器还可以接受服务器反馈的采集频率调控信息，并根据该采集频率调控信息调节当前道路上对车辆图像的采集频率。这样图像采集器可以根据实际的交通路况来适应性进行调整，提高采集效率，例如，在发生交通状况时，可以提高采集频率，在道路通信顺畅时，降低采集频率等。
在某些实施方案中，车辆信息还包括图像采集时刻和图像采集器的标识。实施例中提供的采集频率调控信息的生成方式，可以包括如下过程：
A：服务器通过wifi6路由器接收图像采集器照预设采集频率采集到的车辆图像，并根据图像采集时刻和图像采集器的标识得到图像采集器在预设时间段内采集到的序列车辆图像，序列车辆图像包含多张车辆图像；
B：服务器根据序列车辆图像判断当前道路上的交通状况，交通状况包括正常车流下的正常通行、较少车流下的正常通行或交通拥堵。其中，正常车流为单位时间内道路上通过的车辆数量大于预设数量且车速大于第一阈值，较少车流为单位时间内道路上通过车辆的数量低于预设数量且车速大于第一阈值，交通拥堵为当前道路上的通过车辆的数量低于预设数量且车速不大于第一阈值；
C：当前道路上的交通状况为正常车流下的正常通行时，采集频率调控信息为控制预设频率保持不变；
D：当道路上的交通状况为较少车流下的正常通行时，采集频率调控信息为在预设采集频率的基础上降低采集频率；
由于道路上的车辆较少且正常通信，短时间内一般不会发生交通 拥堵，所以可以降低采集频率来减少能量消耗，并且还可以减轻服务器的压力，提高处理效率；以及
E：当前道路上的交通状况为交通拥堵时，采集频率调控信息为在预设采集频率的基础上增加采集频率；
在前道路上的交通状况为交通拥堵时，为用户最为关心的时间段，很多用户希望早点获知交通拥堵解除的消息，因此，可以提高采集频率，以便能够及时获取到最新的路况信息，一旦拥堵解除，可以第一时间发布到预设导航地图软件中，便于用户可以及时或者该情况。
在某些实施方案中，不但可以根据上述实施例中图像采集器通过所处的当前时刻按照该时刻对应的预设采集频率进行采集，还可以根据服务器反馈的采集频率调控信息调节当前道路上对车辆图像的采集频率。并且在不同的路况下，调控图像采集器的采集频率，以提高采集效率。
为了准确判断道路上的道路状况，基于上述实施例，在本公开提供的又一实施例中，图像采集器上可以设置有定位模块，该定位模块配置为获取所述图像采集器的位置信息。图像采集器设置的采集方向与道路上的车流方向一致，车辆信息还包括定位信息，步骤S130，可以包括如下步骤：
步骤S1，服务器根据定位信息，确定图像信息所属的道路位置；
步骤S2，服务器判断序列车辆图像中是否存在多个局部红色区域的目标车辆图像；其中，局部红色区域为采集到的车辆红色尾灯信息；
如果序列车辆图像中存在多个局部红色区域的目标车辆图像，执行步骤S3；
在步骤S3中，服务器判断多个局部红色区域在目标车辆图像中所占的区域面积是否大于预设面积；
如果多个局部红色区域在目标车辆图像中所占的区域面积大于预设面积，且目标车辆图像为多张且在序列图像中连续存在，在步骤S4中，确定道路的交通状况为拥堵的路况信息。
在某些实施方案中，服务器在接收到图像采集器发送的车辆信息时，会对该车辆信息中的车辆图像进行处理，以通过该车辆图像来判断当前对应道路中的交通情况。
在本公开实施例的完成过程中，如果车辆比较拥堵或者行驶缓慢，车辆基本都会打开红色尾灯。因此，本公开实施例可以通过检测车辆图像中的红灯情况来判断当前对应道路上的路况。本公开实施例通过检测车辆红灯在整个图像中所占的面积，来判断当前对应道路是否发生拥堵，即如果多个局部红色区域在目标车辆图像中所占的区域面积大于预设面积，且目标车辆图像为多张且在序列图像中连续存在，那么就可以确定道路的交通状况为拥堵的路况信息。通过采用这种方式，服务器可以快速实时的进行检测，以便用户可以通过在导航地图软件中发布的路况信息或者相关道路的交通情况。
本公开提供了新的交通信息获取方式，通过在道路上部署wifi6路由器，并且图像采集器通过wifi6路由器利用wifi6技术将采集到的车辆信息发送给服务器，以便将生成的路况信息发布到导航地图中，可以使得用户及时掌握道路的交通情况，便于选择更优的出行路线。在本公开提供的又一实施例中，用户终端还可以加入到wifi6路由器提供的局域网中，因此，基于上述实施例，如图3所示，该方法还可以包括如下步骤：
步骤S140，终端扫描当前区域范围内的预设无线局域网信号，其中，该预设无线局域网信号为目标wifi6路由器发出的无线信号；
步骤S150，终端在扫描到当前区域范围内的预设无线局域网信号时，向目标wifi6路由器发送网络接入请求，以使终端通过wifi6路由器与服务器通信连接；以及
步骤S160，终端通过预设导航地图软件接收服务器发布的当前区域范围内的路况信息。
在某些实施方案中，由于wifi6路由器可以覆盖一定的区域，用户在驾车进入到目标wifi6路由器覆盖的提供预设无线局域网信号时，用 户可以通过车载导航终端或者手机终端等设备接入到该无线局域网中，实现与服务器的交互。对此，用户可以直接通过该局域网获得预设导航地图上的路况信息，而不用再接入其他网络，使得用户在没有其他信号的情况下，也可以及时通过预设导航地图软件了解当前的路况信息。
在某些实施方案中，用户可以通过终端将获取的临时道路信息发送到服务器，该方法还可以包括如下步骤：
S11，终端获取临时道路信息，其中，该临时道路信息用于描述当前所在位置的道路通行情况，临时道路信息是用户基于当前所在的位置获得的图像信息、语音信息或文字描述信息；
S12，终端向wifi6路由器发送临时道路信息；
S13，wifi6路由器将接收到的临时道路信息发送给服务器；以及
S14，服务器将接收到的临时道路信息添加到路况信息中，并发布到预设导航地图软件中。
在某些实施方案中，终端在加入到wifi6路由器提供的局域网中后，用户可以通过车载导航终端或者手机终端，将自己对当前道路上了解到或者看到的情况，以图片、视频、语音或者文字描述等临时道路信息通过wifi6路由器发送给服务器，服务器在接收到该临时道路信息后，通过预处理后发布到导航地图上，便于其他用户可以了解到更多的情况，其他用户也可以对此进行评论或者打分等。
在某些实施方案中，服务器通过wifi6路由器接收用户对路况信息的评论信息；评论信息为目标用户在将临时道路信息发布后，其他用户对临时道路信息进行的评价；服务器在检测到临时道路信息被更新后，将临时路况道路信息删除或者标记为历史事件。这样可以及时更新路况信息，避免因没有及时更新路况信息误导其他用户。
在某些实施方案中，服务器通过wifi6路由器接收用户对路况信息的打分分值，打分分值用户衡量临时道路信息的准确度，打分分值与临时道路信息的准确度正相关。服务器在检测到打分分值低于预设分 值时，将临时道路信息删除。这样通过用户之间的互动，可以提高用户发布的临时道路信息的准确性，避免个别错误信息误导其他用户的出行选择。
