下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
鉴于地图数据质量规范以及图商的地图评价体系中缺乏统一的地图评价标准，本申请提供了一种地图评估方法，该方法包括：获取待评估地图；获取待评估地图对应的第一配置文件，该第一配置文件用于指示待评估地图的多个评分维度；从多个评分维度中选择第一评分维度；确定第一评分维度的第一权重；根据第一评分维度和第一权重，对待评估地图进行评估。如此，可以实现灵活设置待评估地图的评分维度，使得用户可以基于自身需求对待评估地图进行评估，进而有助于用户选择符合其偏好需求的地图产品。
在介绍本申请实施例提供的地图评估方法之前，首先对本申请实施例适用的***架构进行详细的介绍。
图1为本申请实施例适用的一种可能的***架构示意图，如图1所示的***架构包括采集设备110、服务器120和电子设备130。
采集设备110是指能获取真实交通网络中的环境信息的设备，如可以包含但不限于如下类型的设备：
第三方服务器111，是指独立于服务器120和电子设备130以外的、且具有共享功能的第三方机构中设置的服务器。在车联网领域中，第三方机构通常可以设置为交通运输体系的管理者，如国家交通运输管理部、各级城市交通运输管理处或管理所等。交通运输体系的管理者具有实时监管交通运输体系中各条交通线路的能力，不仅能及时获知各条交通线路的通行情况，还能对交通线路的通行方式作出一定的改变，如更改某条交通线路的限速。通过第三方机构中设置的服务器也可以获得道路的环境信息。再比如，该服务器可以是车联网服务器，车联网服务器可以通过维护和更新高精地图(high definition map，HD MAP)的信息，为车联网终端提供规划和控制服务，还可以维护和更新地图的信息，为车联网终端提供导航服务。
路侧单元(road side unit，RSU)112，是指安装在道路一侧或两侧的具有通信功能的装置。通常情况下，路侧单元能在车辆经过时与车辆上的车载单元(on board unit，OBU)建立连接，实现对车辆的身份识别。在本申请实施例中，路侧单元中还可以封装诸如摄像头、雷达或激光发射器等的功能模块，路侧单元能通过这些功能模块实时监测所在道路，在道路环境发生变化时及时获知变化后的环境信息；
车辆113，具有摄像功能、传感功能等采集功能，可以采集车辆周围的环境信息。辆的摄像装置可以是单目摄像头、双目摄像头等。摄像装置的拍摄区域可以为车辆的外部环境。车辆的传感装置可以包括用于获取环境信息的激光雷达、毫米波雷达、超声波雷达等雷达，以及还可以包括用于获取车辆位姿的惯性导航***(例如，全球导航卫星***(global navigation satellite system，GNSS)，惯性测量单元(Inertial measurement unit，IMU))等。GNSS可以用于估计车辆的地理位置。为此，GNSS可以包括收发器，基于卫星定位数据估计车辆相对于地球的位置。在示例中，车辆中的计算机***可以结合地图数据使用GNSS来估计车辆行驶的道路。IMU可以基于惯性加速度及其任意组合来感测车辆的位置和朝向变化。在一些示例中，IMU中传感器的组合可包括例如加速度计和陀螺仪。将基于GNSS得到的定位信息和基于其它技术(例如，IMU)得到的信息融合，将融合后的结果作为车辆的当前时刻的全局位姿。这种将基于GNSS得到的信息和基于其它技术(例如，IMU等传感器)得到的信息进行融合以实现定位的方式可以称为组合定位。当然，组合定位还可以通过其他传感器采集到的数据与高精地图中存储的相应的传感器的数据进行匹配，可以实现对车辆当前所在的车道级的定位位置。例如，毫米波雷达传感器可利用无线电信号来感测车辆的周边环境内的目标。在一些实施例中，除了感测目标以外，毫米波雷达还可用于感测目标的速度和/或前进方向。激光雷达可利用激光来感测车辆所位于的环境中的目标。传感器可用于捕捉车辆的周边环境的多个图像。另外，每辆车可以设置一种或多种传感器，每种传感器的数量可以为一个或多个。传感器可以安装在车辆的顶部(例如可以设置在车辆顶部的中间位置)、车辆前端等等位置，本申请实施例对每个车辆中传感器安装位置和数量并不做限定。
其中，服务器120可以是指单个服务器，也可以是指由多个服务器构成的服务器集群。在车联网领 域中，该服务器120具体可以是云服务器，也称为云、云端、云端服务器、云端控制器或车联网服务器等。云服务器是对具有数据处理能力的设备或器件的统称，诸如可以包括主机或处理器等实体设备，也可以包括虚拟机或容器等虚拟设备，还可以包括芯片或集成电路。
其中，电子设备130可以是具有地图评估功能的智能终端或任意车辆，车辆包括但不限于轿车、公交车甚至货车等。电子设备130通常还可以在服务器120上进行注册，以便获取服务器120所提供的各项服务，诸如语音服务、地图评估服务、自动驾驶服务、航班查询服务或语音播报服务等。
应理解，本申请实施例对***架构中采集设备的种类和数量、服务器的数量以及用户车辆的数量均不作限定，例如1个服务器可以只与1种采集设备(如第三方服务器111)和1台用户车辆进行信息交互，也可以与多种采集设备(如路侧单元112和车辆113)和1台用户车辆进行信息交互，还可以与多种采集设备和多台用户车辆进行信息交互。两个设备之间的信息交互可以是指这两个设备通过有线方式或无线方式直接交互，也可以是指这两个设备通过一个或多个其它设备间接交互。且，本申请实施例所适用的***架构中除了包括采集设备、服务器和用户车辆以外，还可以包括其它设备，如终端设备、网络设备、核心网设备等，对此本申请实施例也不作限定。以及，本申请实施例中的任一设备可以将功能集成在一个独立的物理单元上，也可以将功能分布在多个独立的物理单元上，对此本申请实施例也不作限定。
基于图1所示意的***架构，当电子设备130具有地图评估功能时，采集设备110获取真实交通网络中的环境信息之后，可以将该环境信息上传至服务器120；进而服务器120根据该环境信息，构建待评估地图；进而电子设备130可以预先从服务器120中获取待评估地图，并对待评估地图进行评估。
以上介绍了本申请实施例适用的***架构，下面结合具体的附图介绍本申请实施例提供的地图评估方法。
【实施例一】
图2示例性示出本申请实施例一提供的一种地图评估方法对应的流程示意图，该方法适用于具备地图评估功能的电子设备(例如可以是如图1所示意的电子设备130)。如图2所示，该方法包括：
S201，电子设备获取待评估地图。
在本申请实施例中，待评估地图即需要进行评估的地图。其中，电子设备获取待评估地图包括但不限于以下实施方式：
在一种可能的实施方式中，电子设备接收用户指令，该用户指令用于指示待评估地图；进而电子设备可以响应于用户指令，向地图服务器(例如服务器120)请求待评估地图。如此，用户可以灵活选择待评估地图。
在另一种可能的实施方式中，车辆在采集到环境信息时，根据环境信息生成相应的待评估地图，并将待评估地图发送至电子设备。相应的，电子设备接收待评估地图。如此，可以实现对实时更新的地图进行评估。
S202，电子设备获取待评估地图对应的第一配置文件，该第一配置文件用于指示待评估地图的多个评分维度。
在本申请实施例中，第一配置文件可以是基于地图数据质量规范和/或图商推荐的地图评价标准预设的，或者，也可以是用户参考地图数据质量规范和/或图商推荐的地图评价标准自定义的，本申请不作具体限制。相应的，电子设备获取待评估地图对应的第一配置文件包括但不限于以下实施方式：
在一种可能的实施方式中，电子设备可以从第三方服务器(例如可以是图商服务器或政府管理机构对应的服务器)获取预设的第一配置文件。
在另一种可能的实施方式中，电子设备可以提供第一配置文件对应的用户操作界面，接收用户针对用户操作界面的输入信息，并根据该输入信息生成相应的第一配置文件。其中，该输入信息例如可以是语音信息、文字信息、图形信息、或手势信息中的任一项。
在上述步骤202中，多个评分维度包括覆盖场景信息、图层属性信息、安全认证信息、产品格式信息、产品体量信息、更新维护信息、生态建设信息、或行业定制化信息中的至少一项；其中，覆盖场景信息用于描述待评估地图的使用场景，图层属性信息用于描述待评估地图中的至少一个图层的质量，安全认证信息用于描述待评估地图的安全等级和/或合规性，产品格式信息用于描述待评估地图支持的标准体系；产品体量信息用于描述待评估地图的产品形态和/或数据包大小；更新维护信息用于描述待评估地图的更新范围和/或更新频率；生态建设信息用于描述待评估地图在不同地图使用设备中的数据兼 容性；行业定制化信息用于描述待评估地图适用的第一行业的使用需求。如此，提供了多个评分维度的实施方式，进而用户可以灵活设置自己偏好的评分维度。下面对这些评分维度进行介绍：
(1)、覆盖场景信息用于描述待评估地图的使用场景，可以理解为覆盖场景信息用于描述待评估地图覆盖的物理空间，即待评估地图的应用场景。示例性的，考虑按不同物理空间对交通参与者的限制程度，覆盖场景可以包括但不限于封闭园区道路、专用道路、高功能等级道路、或城市普通道路。如此，将覆盖场景信息作为评分维度对地图进行评估，有助于用户选择满足其使用场景的地图产品。
(2)、图层属性信息用于描述待评估地图中的至少一个图层的质量，可以理解为图层属性信息用于描述待评估地图中各个图层中的组成要素的质量水平，其中，各个图层中的组成要素的质量水平可以通过图层要素的正确率来表征。可选的，图层要素的正确率可根据图层要素的完整性、逻辑一致性、专题准确度、数值准确度、和时间质量确定。其中，图层要素例如可以包括图层中的交通元素、道路几何元素等。如此，将图层属性信息作为评分维度对地图进行评估，有助于用户选择满足其图层要素质量水平的地图产品。
在一种可能的实施方式中，图层属性信息对应的至少一个图层包括动态图层和/或静态图层；其中，动态图层为交通事件图层、交通流量信息图层、实时感知图层、气象环境图层、或统计应用图层；静态图层为车道拓扑图层、道路拓扑图层、道路交通标线、标志图层、或路侧及路内设施图层。在该实施方式中，考虑到现实世界中的真实交通环境存在实时变化的特性，为提高地图评估的准确性，将图层属性信息维度对应的至少一个图层设置为动态图层或静态图层。如此，可以使得基于图层属性信息维度对待评估地图的评估结果更加准确。下面对这些的含义进行说明。
a)车道拓扑图层，包括车道中心线的线段和结点构成的拓扑连接网络信息。
b)道路拓扑图层，包括道路参考线、道路虚拟连接线和道路结点构成的拓扑连接网络信息。

h)气象环境图层，包括与出行和道路行驶相关的天气信息、光照情况、以及道路摩擦系数等信息。
i)统计应用图层，包括用统计方法获得的事故频发路段信息，以及用户自定义或电子设备通过学习用户行为获得的用户行为偏好信息。
在一种可能的实施方式中，至少一个图层包括多个图层，相应的，至少一个图层的质量是通过对多个图层的质量分数进行加权运算得到的一个质量分数。如此，电子设备可以结合多个图层的质量分数，来确定至少一个图层的质量分数，进而可以通过该质量分数来表征至少一个图层的质量，实现了在图层属性信息维度对待评估地图的量化评估，使得用户可以基于图层属性信息维度对应的质量分数，直观地选择符合其偏好需求的地图产品。
示例性的，至少一个图层包括图层A、图层B、和图层C，图层A的质量分数为90分，图层A对应的权重值为0.35；图层B的质量分数为95分，图层B对应的权重值为0.35；图层C的质量分数为97分，图层C对应的权重值为0.3；进而电子设备可以对图层A、图层B、和图层C的质量分数进行加权运算：(90*0.35+95*0.35+97*0.3)＝93.85，并将93.85作为至少一个图层的质量分数。
可选的，多个图层中每个图层的质量分数可以根据该图层中的地图要素的准确率确定。示例性的，图层的质量分数与图层中的地图要素的准确率之间存在如表1所示的映射关系，进而电子设备可以根据表1所示的映射关系，确定每个图层的质量分数。

由前文描述可知，第一评分维度可以包括一个或多个评分维度，相应的，第一权重也包括一个或多个权重的取值。
在上述步骤204中，第一权重用于表征用户对第一评分维度的重视程度。相应的，若用户对第一评分维度较为重视，可以将第一权重设置为较大的取值；若用户对第一评分维度不重视，可以将第一权重设置为较小的取值。
在本申请中，电子设备确定第一评分维度的第一权重包括但不限于以下实施方式：
实施方式1，电子设备接收第三指令，该第三指令用于指示第一评分维度的第一权重；进而电子设 备可以根据第三指令，确定第一评分维度的第一权重。可选的，第三指令可以为人机交互指令，例如可以是语音指令、触摸指令、或文字指令中的任一项。如此，用户可以灵活设置第一评分维度的第一权重，使得基于第一评分维度进行的地图评估更加符合其偏好需求，从而进一步提升用户的地图评价体验。

【实施例二】
在实施例二中，考虑到不同用户对地图产品的基本需求不一致，针对待评估地图还设置了第二配置文件，因此电子设备可以获取待评估地图对应的第二配置文件，基于第二配置文件，确定待评估地图是否满足第一条件。如此，使得对待评估地图的评估过程更加合理，以及可以提升用户的地图评估体验。
图5示出本申请实施例二提供的一种地图评估方法对应的流程示意图，该方法适用于具备地图评估功能的电子设备(例如可以是如图1所示意的电子设备130)。如图5示，该方法包括：
S501，电子设备获取待评估地图。
S502，电子设备获取待评估地图对应的第一配置文件，该第一配置文件用于指示待评估地图的多个评分维度。
S503，电子设备从多个评分维度中选择第一评分维度。
S504，电子设备确定第一评分维度的第一权重。
S505，电子设备获取待评估地图对应的第二配置文件，第二配置文件用于确定待评估地图是否满足第一条件。
可以理解的是，第二配置文件可以是用户参考地图数据质量规范、图商推荐的地图评价标准或基于其应用需求(例如智能驾驶应用)自定义的，本申请不作具体限制。
在S505中，第一条件用于表征用户对待评估地图的基本要求。因此，电子设备可以根据第二配置文件，确定待评估地图是否满足用户的基本需求，使得用户对待评估地图的评测体验更好。第一条件包括以下内容中的至少一项：
待评估地图适用于第一使用场景。示例性的，第一使用场景例如可以是封闭园区道路、专用道路、高功能等级道路、或城市普通道路等。
待评估地图中的第一图层的质量分数大于第一阈值。示例性的，第一图层包括交通事件图层、交通流量信息图层、实时感知图层、气象环境图层、统计应用图层、车道拓扑图层、道路拓扑图层、道路交通标线、标志图层、或路侧及路内设施图层。第一阈值例如可以是90％。

待评估地图满足第一行业的使用需求。示例性的，第一行业为无人机物流行业，无人机物流行业的使用需求为地图产品中应备道路网络结构和道路几何要素。
如此，提供了第一条件的多种实现方式，进而使得用户可以在第二配置文件中设置多样化的基本需求。
示例1，第一条件可以如表5所示，第一条件包括：条件1，地图中包含A城区公交专用道路；条件2，地图中车道拓扑图层要素正确率不小于98％；条件3，地图需通过ISO 26262认证。其中，待评估地图包含A城区公交专用道路，则待评估地图满足条件1；待评估地图的车道拓扑图层要素正确率为98％，则待评估地图不满足条件2；待评估地图通过ISO 26262认证，则待评估地图满足条件3；待评估地图支持洒水车智能驾驶及路面清洗作业，则待评估地图满足条件4；待评估地图的更新周期为按秒更新，则待评估地图满足条件5；待评估地图支持NDS、OpenDRIVE标准格式，则待评估地图满足条件6；待评估地图产品体量不大于120M，则待评估地图满足条件7；虽然待评估地图满足条件1、条件3-条件7，但是待评估地图不满足条件2，则电子设备将待评估地图判定为不满足第一条件。

表6
S506，电子设备基于第二配置文件，确定待评估地图是否满足第一条件。
在S506中，将用户对待评估地图的基本需求地图评估的顶层决定性指标，在确定待评估地图满足第一条件之后，才根据第一评分维度和第一权重，对待评估地图进行评估，使得待评估地图的评估过程更加合理，可以有效防止在待评估地图不满足用户基本需求的情况下对地图进行评估，避免浪费用户时 间，有效提升用户的地图评估体验。
S507，电子设备根据第一评分维度和第一权重，对待评估地图进行评估。
在一种可能的实施方式中，电子设备在待评估地图不满足第一条件时，将待评估地图的质量评估为最低等级或最低分数。其中，第一条件用于表征用户对待评估地图的基本需求。如此，将用户对待评估地图的基本需求地图评估的顶层决定性指标，在待评估地图不满足第一条件时，将待评估地图的质量评估为最低等级或最低分数，如此可以直观反映地图产品是否满足用户的基本需求。
【实施例三】
为了便于理解，在实施例二的基础上，实施例三结合具体的应用场景对本申请实施例提供的地图评估方法进一步介绍。
请参见图6，图6示出本申请实施例提供的用户操作界面的示意图之三。在图6中，评分维度包括覆盖场景信息、图层属性信息、安全认证信息、产品格式信息、产品体量信息、更新维护信息、生态建设信息、和行业定制化信息。其中，评分维度可以理解为待评估地图的产品画像。用户可以在图6中配置符合其偏好需求的评分维度，例如，用户可以选择覆盖场景信息、图层属性信息、安全认证信息、产品格式信息、产品体量信息、更新维护信息、生态建设信息、和行业定制化信息作为第一评分维度，并输入相应的确认指令，进而电子设备可以根据该确认指令，确定第一评分维度。
如表7所示，覆盖场景信息的评分项包含封闭园区道路和专用道路，而待评估地图包含A景区道路和B城区公共专用道路，则待评估地图在覆盖场景信息维度的得分是100；图层属性信息维度的评分项包含车道拓扑图层的要素正确率、道路拓扑图层的要素正确率、道路交通标线及标志图层的要素正确率、路侧及路内设施图层的要素正确率、交通事件图层的要素正确率、交通流量信息图层的要素正确率、实时感知图层的要素正确率、气象环境图层的要素正确率、统计应用图层的要素正确率，且待评估地图在图层属性信息维度的得分是96.5；待评估地图通过ISO 26262认证，则待评估地图在安全认证信息维度的得分是100；待评估地图支持NDS、OpenDRIVE标准，则待评估地图在产品格式信息维度的得分是100；待评估地图的数据包大小120M，则待评估地图在产品体量信息维度的得分是90；生态建设信息的评分项包含生态圈范围和具有多源适配性，而待评估地图包含覆盖范围内所有学校和可兼容云端数据，则待评估地图在生态建设信息维度的得分是80；行业定制化信息的评分项包含支持交通行业特定场景和支持物流行业特定场景，而待评估地图支持洒水车智能驾驶并完成路面清洗，以及支持园区内智慧物流无人车运输快递，则待评估地图在生态建设信息维度的得分是100。
表7

进一步的，用户针对覆盖场景信息、图层属性信息、安全认证信息、产品格式信息、产品体量信息、更新维护信息、生态建设信息、和行业定制化信息，设置了如表8所示的权重值，进而电子设备根据各个评分维度的得分和相应的权重，计算得到待评估地图的总分数为94.95分。
表8
进一步的，用户设置如表9所示的评级规则，根据表9可知，待评估地图的总分数为94.95分时，待评估地图对应的等级为A。
表9
可选的，用户还可以设置第一条件，第一条件以车道拓扑图层的要素正确率大于99％为例，待评估地图中的车道拓扑图层的要素正确率大于98％，则待评估地图不满足第一条件，因此将待评估地图设置为最低等级。
