Description

定位方法和装置
本申请要求于2021年03月30日提交中国专利局、申请号为202110342456.6、申请名称为“定位方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种定位方法和装置。
背景技术
随着城市交通的发展，立交桥的数量越来越多，其建造也越来越复杂。例如包含多层路面的立交桥。当用户使用导航驶入立交桥时，由于立交桥在同一位置设有多层路面，这就使得导航无法区分当前用户位于立交桥的哪一层，进而无法根据准确的路面层提供准确的导航路线；尤其是当用户根据导航路线走错之后，导航软件无法及时识别用户当前所在立交桥的哪一层，进而无法及时更新正确的导航路线，从而给用户在立交桥上行驶过程中带来极大麻烦。
现有可能的设计中，可以利用射频识别(radio frequency identification，RFID)对立交桥的路面层进行定位。例如，可以在路面上铺设RFID标签，并基于车辆经过该路面时接收到的RFID发射的信号，对车辆所在的路面层进行定位识别。
然而，由于RFID的识别宽度有限，可能会由于在道路中的车辆距离RFID标签较远，出现车辆无法识别到路面的RFID标签发送信号的情况，进而无法对车辆在立交桥中所处的路面层进行精准定位；除此以外，在立交桥路面铺设RFID，一方面容易被车辆压坏，另一方面需要破坏现有路面进行铺设，工程量大。

具体实施方式
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一值和第二值仅仅是为了区分不同的值，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
随着城市交通的发展，立交桥和隧道的数量越来越多，其建造也越来越复杂。例如包含多层路面的立交桥。立交桥给交通带来便利的同时，也给路面导航带来了挑战。通常情况下，当用户使用导航驶入立交桥时，由于立交桥在同一位置设有多层路面，这就使得导航无法区分当前用户位于立交桥的哪一层。可能会出现，用户已经驶入了错误的路面层，但导航仍按照用户行驶在正确的路面层上指示路线。
可以理解的是，本申请实施例的立交桥也可以替换为包括主路和辅路的道路，该主路和辅路可以在同一层，也可以在不同的层，通常情况下，导航无法区分主路和辅路，导致也不能为用户实现精准导航。适应的，该路面层也可以称为道路层。该路面层可以用于表示多层路面中不同层的路面；或者，该路面层也可以表示同一层路面中不同的道路，例如，相邻的道路中的主路和辅路，可以用不同的路面层表示。
为便于描述，后续均已立交桥和路面层进行描述，该描述并不构成对场景的具体限定。
示例性的，图1为本申请实施例提供的一种场景示意图。如图1所示，该场景中包括立交桥100。该立交桥100中包括多个道路：例如道路101、道路102和道路103。其中，道路101可以为一层的道路，用于驶入立交桥；道路102可以为二层的道路；道路103可以为三层的道路。示例性的，车辆104可以沿道路101驶入立交桥100，该车辆104可以沿箭头②所指示的方向驶入道路102，或者该车辆104也可以沿箭头①所指示的方向驶入道路103。
在道路101上，车辆104可以基于导航106所指示的路线行驶。其中，该导航106可以为：车载导航或手机导航等。
该立交桥100中可以包括多个摄像头，例如设置在专门的摄像头固定杆上的摄像头112，设置在路灯上的摄像头108，设置在广告牌上的摄像头110，或者设置在桥下的摄像头111等。可以理解的是，该摄像头可以根据实际场景设置在其他位置上，本申请实施例中对此不做限定。
示例性的，在图1对应的场景中，用户按照导航106指示的路线，驾驶车辆104沿道路101驶入立交桥100，用户本应该根据导航106指示的路线驾驶车辆104行驶在道路103上，但用户驾驶车辆104行驶到了道路102上。导航106本应该及时发现用户行驶路线错误，进而导航106可以根据道路102为用户重新规划路线。但是，由于导航106无法区分当前用户位于立交桥的哪一层，也就无法识别用户已经走错了路线，例如，用户已经驾驶车辆104行驶到了道路102上，因为道路102和道路103在经纬度定位或GPS定位中，位置几乎一致，所以导航不能识别到用户不在导航所指示的道路103上行驶，进而导航也就无法基于正确的路面层给用户提供准确的路线。
现有技术中提供了一种基于RFID的立交桥智能导航方法。具体的，可以在立交桥上设置RFID标签，当车辆判断当前道路为立交桥道路(或其他多层路面的道路)时，可以使用射频天线接收设置于立交桥上的RFID标签发送的信息，该信号可以为带有当前所在的道路编号的射频信号，进而车辆可以准确的知道自身所在的路面层，并基于获取的GPS定位信号、道路编号和行车路线进行导航。
然而，上述方法存在以下问题：其一，使用GPS进行定位时，由于GPS定位信号的定位精度在十米左右，在立交桥密集处就会发生导航不准甚至导航错误的情况；其二，将射频天线设置在车辆的底部，且将RFID标签设置在道路地面下方的方法，需要将RFID铺设到立交桥路面上，这种情况下，RFID不仅容易被来往的车辆压坏，而且其铺设RFID的工程量大，也很容易破坏现有路面，成本较高；其三，RFID的识别宽度有限，车辆的在道路中距离RFID标签较远，可能出现车辆无法识别到路面的RFID标签发送信号的情况。
有鉴于此，本申请实施例提供一种定位方法，可以充分利用设置在多层路面中的摄像头，并基于多层道路中的摄像头与路面层的对应关系，精准判断用户位于该多层道路中的哪一层，进而接收到该路面层信息的终端设备可以基于准确的路面层进行导航。其中，该终端设备可以为具有导航能力的车辆或手机等设备。
可以理解的是，上述终端设备也可以称为终端，(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、智能电视、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。

本申请实施例中，GPS定位信息可以用于标识终端200所在的位置，或者用于确定终端200所在的多层路面的位置，该GPS定位信息可以由终端200中的GPS定位模块生成。例如，终端200可以将实时获取的GPS定位信息发送至导航服务器302；相应的，导航服务器302可以实时对终端200进行定位，进而确定终端200所在的位置。
可以理解的是，此时导航服务器302中可以保存有从S601中获取的车牌信息，以及从S602中获取的GPS定位信息的对应关系。
示例性的，如图4所示的场景中，当终端200驶入多层路面的路口时，终端200中的GPS定位模块可以识别到车辆进入多层路面，并实时将该车辆所在的位置发送至导航服务器302。此时车辆可以按照终端200中的导航软件指示的路线继续行驶。
S603、导航服务器302获取摄像头拍摄的车牌照片，以及该车牌照片对应的摄像头编号。
本申请实施例中，该车牌照片可以用于识别车辆。该车牌照片可以为摄像头拍摄的包含车牌信息的照片。其中，该摄像头可以为多层路面中的至少一个摄像头。
示例性的，导航服务器302中可以获取来自多个摄像头(例如图4所示的场景中的，摄像头403、摄像头404以及摄像头405)拍摄的车牌照片，以及该车牌照片对应的摄像头编号。本申请实施例中的摄像头可以具有图像识别能力，或者，不具有图像识别能力，其中图像识别能力用于将拍摄的车牌照片进行图像识别，识别出准确的车牌信息。其中，导航服务器302可以控制摄像头拍摄车牌照片，或者导航服务器302可以获取连续拍摄的摄像头上传至导航服务器302的照片中，所需的照片。
一种实现中，当该摄像头具有图像识别功能时，该多层路面的摄像头可以拍摄多张车牌照片，并基于摄像头中的图像处理模块识别出该车牌照片中的车牌信息，并将该车牌信息，以及该车牌信息对应的摄像头编号上传至导航服务器302，后续导航服务器302可以执行S605所示的步骤。
另一种实现中，当该摄像头不具有图像识别功能时，该多层路面的摄像头可以拍摄多张车牌照片，并将该车牌照片，以及该车牌照片对应的摄像头编号上传至导航服务器302，导航服务器302具有图像识别能力，后续导航服务器302可以执行S604所示的步骤。
S604、导航服务器302对车牌照片进行图像处理，得到车牌信息。
S605、导航服务器302根据车牌信息和摄像头编号，确定该车辆对应的路面层。
本申请实施例中，导航服务器302中可以保存有摄像头编号与路面层的对应关系。如图4所示的场景中，该摄像头与路面层的对应关系如下表1所示：
表1 摄像头编号与路面层对应示意表
摄像头编号 路面层
摄像头403 ①
摄像头404 ②
摄像头405 ③
其中，摄像头403与路面层①对应，摄像头404与路面层②对应，摄像头405与路面层③对应。
示例性的，导航服务器302可以获取多组车牌信息和摄像头编号的对应关系。进一步的，导航服务器302可以根据S601所示的步骤中上传的车牌信息，如某12345，在该多组车牌信息和摄像头编号的对应关系中，确定该某12345对应的摄像头编号，如摄像头404。进而，如表1所示，导航服务器可以根据摄像头404，确定该终端200位于路面层②。
S606、导航服务器302将路面层信息发送至终端200。
适应的，终端200可以确定是否接收到该导航服务器302发送的路面层信息。
一种实现中，若终端200接收到该路面层信息，则终端200中的导航软件可以显示该路面层信息。该路面层信息用于指示该路面位于多层路面中的层级，该路面层信息可以为路面层编号等其他形式，例如路面层②。
示例性的，图8为本申请实施例提供的一种的显示路面层的界面示意图。在图8对应的实施例中，以终端200为手机为例进行示例说明。手机接收到导航服务器发送的该手机位于路面层②的信息时，手机中的导航软件可以显示如图8所示的界面。如图8所示，可以在手机左半屏的指示信息801中显示当前车辆位于路面层②的信息，以及在手机右半屏中显示路面层②对应的路线。
另一种实现中，若终端200未接收到该路面层信息，则终端200中的导航软件可以继续按照原导航算法继续导航。
示例性的，图9为本申请实施例提供的另一种的显示路面层的界面示意图。在图9对应的实施例中，以终端200为手机为例进行示例说明。当手机未接收到路面层信息时，手机中的导航软件可以显示如图9所示的原导航路线的界面，如沿路面层①指示的导航路线。如图9所示，可以在手机左半屏中显示当前车辆正在行驶的方向和行驶方向的说明，以及在手机右半屏中显示原导航算法指示的路面层①对应的路线。
基于此，在多层路面的场景中，导航服务器可以根据摄像头与路面层的对应关系，实现路面层的精准定位，进而为用户提供更准确的导航路线，且本申请实施例可以充分利用导航服务器等设备现有的功能，无需搭建新的服务器，降低实施成本。
在图6对应的实施例的基础上，可能的实现方式中，在S605确定路面层后，可以基于以下几种方法实现路面层的更新，或者维持当前的路面层。
一种实现中，导航软件可以基于路面层的权重，实现路面层的更新，或者维持当前的路面层。
示例性的，当利用摄像头对终端所在的路面层进行定位后，导航服务器可以为该摄像头确定的路面层设置较高的权重；当终端的GPS定位信息指示该终端所在的车辆位于其他路面层时，导航服务器可以为该GPS定位信息指示的路面层设置较低的权重。当导航软件接收到基于摄像头确定的路面层后，接收到该GPS定位信息指示的路面层，由于该GPS定位信息确定的路面层的权重低于摄像头确定的路面层的权重，因此，后续导航软件可以以摄像头确定的路面层信息为准，且可以忽略该GPS定位信息指示的路面层信息。
基于此，对不同设备确定的路面层，设置不同的权重，可以在不同的适用条件下， 根据该权重得到更准确的路面层信息，进而导航软件可以基于该准确的路面层信息，为用户提供更准确的导航路线。
另一种实现中，导航软件可以基于时间，实现路面层的更新，或者维持当前的路面层。
示例性的，当利用摄像头对终端所在的路面层，例如路面层①进行定位后，导航软件可以在一定时间阈值内，以该路面层①为准，且不对路面层①进行更新。当超过该时间阈值时，导航软件可以重新请求获取该车辆所在的路面层的信息。例如，导航服务器可以在得到路面层时，为该路面层设置有效时间。如为该路面层①设置有效时间，1分钟。当终端的导航软件获取基于摄像头确定的当前位于路面层①的信息时，在该路面层①的1分钟的有效时间内，导航软件可以不对该路面层①进行更新。可以理解为，在该1分钟之内，即使导航软件接收到其他设备发送的路面层信息，也不对该路面层①进行更新。当超出路面层①的有效时间时，导航软件可以以接收到的新的路面层信息为准。
又例如，导航软件可以接收到GPS定位模块指示的路面层信息，以及接收到基于摄像头确定的路面层信息。由于传输延迟，当导航软件先接收到GPS定位模块指示的路面层信息为路面层②，并将原路面层更新至路面层②；随后接收到基于摄像头确定的路面层信息为路面层②，此时由于车辆可能已经行驶了一段距离，这时接收到的基于摄像头确定的路面层信息可能不够准确了，因此可以丢弃该摄像头确定的路面层信息，维持当前的路面层。
基于此，对不同设备确定的路面层，设置不同的时间，可以在不同的时间条件下，获得该段时间内更准确的路面层信息，进而导航软件可以基于该准确的路面层信息，为用户提供更准确的导航路线。
又一种实现中，导航软件可以基于用户在终端上报的路面层，实现路面层的更新。
示例性的，图10为本申请实施例提供的一种用户上报的界面示意图。在图10对应的实施例中，以终端200为手机为例进行示例说明。由于用户可以确定驾驶车辆位于多层路面中的哪一层。因此，当手机中的GPS定位模块检测到车辆驶入多层路面后，可以向用户发送提示信息，如图10中的a所示的界面，可以在手机左半屏的指示信息1001中显示请选择当前行驶路面层，并在手机右半屏中显示未接收到用户上报路面层信息前的，导航软件指示的路面层②对应的导航路线。当用户触发路面层①对应的控件时，响应于用户的触发操作，手机中的导航软件可以由图10中的a所示的界面切换至如图10中的b所示的界面。在如图10中的b所示的界面中，手机左半屏的指示信息1002中可以显示：已为您切换至路面层①对应的路线的信息，并在在手机右半屏中显示接收到用户上报路面层信息后的，导航软件指示的路面层①对应的导航路线。
基于此，导航软件可以在不同的场景中，基于用户上报的路面层信息，获得当前较为准确的路面层信息，进而导航软件可以为用户提供更准确的导航路线。
对于场景二，示例性的，图11为本申请实施例提供的一种基于导航服务器和交通平台服务器定位的流程示意图。如图11对应的实施例中，以采集模块为摄像头进行示例说明。其中，图5中的采集模块403也可以理解为摄像头403，图5中的采集 模块404也可以理解为摄像头404，图5中的采集模块405也可以理解为摄像头405，图5中的车辆401也可以理解为终端200。示例性的，基于导航服务器和交通平台服务器定位的方法可以包括如下步骤：
S1101、终端200获取车牌信息，并将该车牌信息发送至导航服务器302。
可以理解的是，S1101与图6对应的实施例中S601所示的步骤类似，在此不再赘述。
S1102、终端200将GPS定位信息发送至导航服务器302。
导航服务器302可以根据该定位信息确定终端200的位置，或者车辆所在的位置，例如车辆位于哪个立交桥、隧道或多层路面上。
S1103、终端200中的导航软件识别到车辆到达多层路面的路口100米(m)时，设置初始时刻为t0。
其中，导航软件也可以基于车辆到达多层路面Nm时，设置初始时刻。其中，N可以为正整数。
示例性的，终端200中的导航软件可以通过GPS定位模块识别到车辆距离多层路面路口的摄像头位置仅有100米，此时设为t0，并发送触发信号给导航服务器302。
S1104、终端200中的导航软件可以触发导航服务器302向交通平台服务器303发送查询请求。
适应的，交通平台服务器303接收到导航服务器302发送的查询请求。其中，该查询请求中可以包括车辆的车牌信息和/或GPS定位信息等。
可能的实现方式中，该查询请求中也可以包含多层路面的位置信息或多层路面编号(或称为立交桥的标识)等。示例性的，导航服务器302可以基于终端200的GPS定位信息，确定多层路面所在的位置，或者多层路面编号。
可能的实现方式中，该查询请求中也可以包含摄像头编号。示例性的，当导航服务器302中保存有多层路面中的摄像头编号时，导航服务器302可以根据GPS定位信息，定向查询该多层路面中的哪个摄像头拍摄得到的车牌照片或车牌序列等，得到该摄像头的编号。
S1105、交通平台服务器303根据多层路面的位置信息，调取(t0+3)s-(t0+9)s之内该多层路面的位置上所有摄像头拍摄得到的车牌序列A，并将得到的车牌信息与车牌序列A进行对比，获取该车牌信息对应的摄像头编号或路面层信息。
其中，该车牌序列A可以为，多层路面的位置中所有摄像头，在(t0+3)s-(t0+9)s之内，对拍摄得到车牌照片进行图像处理后，得到的多个车牌信息对应的序列。例如，在如图5对应的场景中，交通平台服务器303可以获取摄像头403、摄像头404和摄像头405拍摄得到的车牌序列A。
本申请实施例中，该时间范围的确定方法可以为，例如车辆按照60千米/小时(或16.7米/秒)速度行进，当t0时刻车辆在摄像头前方100m位置时，再过6s，车辆可以行驶到立交桥摄像头所在位置，此时，(t0+6)s时刻，摄像头完成拍摄；由于车辆速度有快慢，因此，可以在前后预留一部分余量，保证大部分情况下摄像头能拍摄到，因此可以将时间范围设置为(t0+3)s-(t0+9)s。可以理解的是，该时间范围可以根据实际场景包括其他内容，本申请实施例中对此不做限定。例如，该时间范围也可以为(t0+4) s-(t0+8)s等。
本申请实施例中，可以由交通平台服务器303，或者导航服务器302获取终端200的路面层信息。
一种实现中，当交通平台服务器303保存有摄像头编号与路面层的对应关系时，获取路面层信息的方法可以为，交通平台服务器303可以将车牌序列A与S1104中获取车牌信息进行对比，如果从车牌序列A中找到该车牌信息，则交通平台服务器303可以查询拍摄该车牌信息对应的摄像头编号，并基于交通平台服务器303保存的摄像头编号与路面层的对应关系，确定该摄像头编号对应的路面层信息，后续可以执行S1106所示的步骤中向导航服务器302发送该路面层信息。
另一种实现中，当导航服务器302保存有摄像头编号与路面层的对应关系时，获取路面层信息的方法可以为，交通平台服务器303可以将车牌序列A与S1104中获取车牌信息进行对比，如果从车牌序列A中找到该车牌信息，则交通平台服务器303可以查询拍摄该车牌信息对应的摄像头编号，后续可以执行S1106所示的步骤向导航服务器302发送该摄像头编号。
进而，导航服务器302可以基于摄像头编号和路面层的对应关系确定车辆所在路面层，后续可以将该路面层信息发送至终端200。
其中，若交通平台服务器303将车牌序列A与S1104中获取车牌信息进行对比，且未从车牌序列A中找到该车牌信息时，可以将空信息返回给终端200。适应的，当终端200接收到该空信息后，该终端200中的导航软件可以继续按照原导航算法继续导航。
S1106、交通平台服务器303将摄像头编号或路面层信息发送至导航服务器302。
适应的，导航服务器302可以接收到该交通平台服务器303发送的摄像头编号或路面层信息。
一种实现中，当导航服务器302接收到该交通平台服务器303发送的摄像头编号时，导航服务器可以基于自身保存的摄像头编号与路面层的对应关系，确定该摄像头编号对应的路面层信息，后续可以执行S1107所示的步骤。
另一种实现中，交通平台服务器303可以基于自身保存的摄像头编号与路面层的对应关系确定路面层信息，当导航服务器302接收到该交通平台服务器303发送的路面层信息时，后续可以执行S1107所示的步骤。
S1107、导航服务器302将路面层信息发送至终端200。
适应的，终端200中接收到该导航服务器302发送的路面层信息，并在导航软件中显示该路面层信息。
基于此，在多层路面的场景中，交通平台服务器和导航服务器可以根据摄像头与路面层的对应关系，实现路面层的精准定位，进而为用户提供更准确的导航路线，且可以充分利用导航服务器或交通平台服务器等设备现有的功能，无需搭建新的服务器，降低实施成本。
在图6对应的实施例或者图11对应的实施例的基础上，可能的方式中，若当前处于雷雨天或雾霾天等，天气恶劣，或者能见度较低的场景中，可能会出现基于摄像头拍摄的车牌照片，识别得到的车牌信息不准确的情况。
示例性的，在下雨天时，摄像头由于天气原因，拍摄的车牌照片可能比较模糊，进而出现摄像头无法识别出该拍摄的车牌照片中的车牌信息，或者，摄像头识别该拍摄的车牌照片中的车牌信息出现错误等情况。因此，当出现该摄像头拍摄得到的车牌信息不准确时，可以通过以下方式，进行纠错。
一种实现中，当处于该天气恶劣的场景中，由于该摄像头拍摄得到的车牌信息可能不准确，因此导航软件可以基于路面层的权重进行纠错。例如，当处于该天气恶劣的场景中，由于该摄像头拍摄得到的车牌信息可能不准确，因此导航软件可以基于摄像头确定的路面层，以及基于GPS定位信息指示的路面层，该两个路面层的权重进行纠错。
示例性的，当利用摄像头对车辆所在的路面层进行定位后，导航服务器可以为该摄像头确定的路面层设置较低的权重；当终端的GPS定位信息指示该终端所在的车辆位于其他路面层时，导航服务器可以为该GPS定位信息指示的路面层设置较高的权重。当导航软件接收到基于摄像头确定的路面层后，接收到该GPS定位信息指示的路面层，由于该GPS定位信息确定的路面层的权重高于摄像头确定的路面层的权重，因此导航软件可以以该GPS定位信息指示的路面层信息为准，对基于摄像头确定的路面层信息进行纠错，并以基于该GPS定位信息指示的路面层信息为准。
基于此，导航软件可以在不同的场景中，根据该权重得到更准确的路面层信息，进而导航软件可以基于该准确的路面层信息，为用户提供更准确的导航路线。
另一种实现中，当处于该天气恶劣的场景中，由于该摄像头拍摄得到的车牌信息可能不准确，因此可以基于路面层间的距离进行纠错。例如，当处于该天气恶劣的场景中，由于该摄像头拍摄得到的车牌信息可能不准确，因此导航软件可以利用基于摄像头确定的路面层，以及基于GPS定位信息指示的路面层，该两个路面层之间的距离进行纠错。
示例性的，当利用摄像头对终端所在的路面层，例如路面层①进行定位后，当终端的GPS定位信息指示该终端所在的车辆位于其他路面层，例如路面层②时，导航软件可以基于路面层①与路面层②之间的距离，判断路面层①是否需要更新。例如，当导航软件确定路面层①与路面层②之间的距离超过某一距离阈值时，可以确定该路面层①不准确，此时导航软件可以以GPS定位信息指示的路面层②为准，对原路面层①进行纠错；当路面层①与路面层②之间的距离未超过某一距离阈值时，可以确定该路面层①准确，此时导航软件可以不对原路面层①进行纠错。
基于此，可以在不同的场景中，导航软件可以根据不同的设备确定的路面层，该路面层间的距离，得到更准确的路面层信息，进而导航软件可以基于该准确的路面层信息，为用户提供更准确的导航路线。
又一种实现中，当处于该天气恶劣的场景中，由于该摄像头拍摄得到的车牌信息可能不准确，因此导航软件可以利用基于用户输入的路面层进行纠错。
示例性的，当用户驾驶车辆行驶在路面层①中，但导航软件显示基于摄像头确定的路面层为路面层②时，用户可以通过更改该导航软件中的路面层信息，对基于摄像头确定的路面层进行纠错。
基于此，可以在不同的场景中，导航软件可以根据用户输入得到相对准确的路面 层，进而导航软件可以基于该准确的路面层信息，为用户提供更准确的导航路线。可以理解的是，本申请实施例提供的界面图只作为一种示例，并不作为本申请实施例的限定。
