一种信息获取方法、装置和计算机可读存储介质
相关申请的交叉引用
本申请要求在2021年03月30日提交华人民共和国知识产权局、申请号为202110342558.8、申请名称为“一种信息获取方法、装置和计算机可读存储介质”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
本申请涉及智能交通技术领域，尤其涉及一种信息获取方法、装置和计算机可读存储介质。
背景技术
随着经济的发展，拥有车辆的用户越来越多，但是由于停车场数量有限，因此导致很多车辆会将车辆停放在路侧。如果一条路段的路侧停放较多的车辆，则驾驶车辆经过该路段则需要格外小心，若条件允许，用户可能希望尽量绕过这些路段。
基于此，如何获取路侧车辆停放信息成为亟需解决的问题。
发明内容
本申请提供一种信息获取方法、装置和计算机可读存储介质，用于获取第一时间段内第一路侧的车辆信息，并据此确定第一路侧上车辆停放情况的信息，进而可以辅助用户更合理的驾驶。
第一方面，提供一种信息获取方法，包括：
获取第一时间段内第一路侧的车辆信息，车辆信息包括车辆的位置信息；
根据车辆信息，确定第一路侧的第一停放信息，第一停放信息是指第一路侧上车辆停放情况的信息。由于可以获取第一路侧的车辆信息，因此可以基于此分析出第一路侧上车辆停放情况的信息，进而可以辅助用户更合理的驾驶。
在一种可能地实施方式中，根据车辆信息，确定第一路侧的第一停放信息之后，还包括：根据第一停放信息，规划源地址与目标地址之间的目标路径。由于现有地图中在进行路径规划时，通常根据道路等级、拥堵状况、收费情况、距离等因素进行路径规划。然而，道路情况复杂多变，比如为了在放学时接孩子，在放学的时间段内学校附近路段的路侧可能会停放较多的车辆，通行效率较低。若在进行路径规划时，不考虑路边停车导致的通行效率低问题，则可能会因为距离较近等因素将车辆导航至该路段。而本申请实施例中若可以基于第一路侧上车辆停放情况的信息进行路径规划，则可以规划处更合理的目标路径。比如可以尽量避开路侧停放车辆较多的路段。
另一方面，很多城市为了缓解停车压力，在不影响道路使用的情况下，在道路上划出一部分停车位，来供车主使用，这部分通常可以称为路侧停车位。由于路侧停车位的信息并不像大型停车场一样有专门的服务器进行管控，因此路侧停车位信息一直以来并未为用户提供，而本申请实施例中可以基于第一路侧上停放的车辆的车辆信息确定第一路侧上车 辆停放情况的信息，进而可以基于第一路侧上车辆停放情况的信息规划是否将用户导航至第一路侧的路侧停车位，从而可以为用户提供更多的停车位的选择。
在一种可能地实施方式中，根据第一停放信息，规划源地址与目标地址之间的目标路径，包括：根据第一停放信息，预测第二时间段内的第二停放信息，第二时间段的时间起始点晚于第一时间段的时间起始点；根据第一停放信息和第二停放信息，规划源地址与目标地址之间的目标路径。在实际应用中，由于路侧停车具有无序性，因此路侧上车辆停放情况会经常发生变动，而在路径规划时，从当前地址行驶至第一路侧可能还需要一段时间，这种情况下，若基于未来的第二时间段内预测的第二停放信息进行路径规划，则可以进一步提高路径规划的合理性。
在一种可能地实施方式中，根据第一停放信息，预测第二时间段内的第二停放信息，包括：根据第一停放信息和预存的至少一个第三停放信息，预测第二时间段内的第二停放信息。由于预存的第三停放信息可能是历史的第一路侧上车辆停放情况的信息，或者可能是依据第一路侧车辆停放情况的规律预设，因此若基于第三停放信息和第一停放信息预测第二停放信息，可以更加贴合第一路侧车辆停放情况的规律，可以进一步提供第二停放信息与实际情况相符合的程度。
在一种可能地实施方式中，第二时间段中的一个时刻为沿第一路径从源地址出发行驶至第一路侧的时刻。如此，则可以更加合理的规划路径。
在一种可能地实施方式中，第一停放信息还包括：第一停放信息对应的节假日信息。预存的至少一个第三停放信息对应的节假日信息与第一停放信息对应的节假日信息匹配。如此，可以依据节假日第一路侧上车辆停放情况的规律去预测第二停放信息，可以进一步提供第二停放信息与实际情况相符合的程度。
在一种可能地实施方式中，第一停放信息包括以下内容中的至少一项：第一路侧的标识；第一路侧的位置信息；或，第一时间段。
在一种可能地实施方式中，第一停放信息中还包括可信度信息。根据第一停放信息和第二停放信息，规划源地址与目标地址之间的目标路径，包括：根据第一停放信息中的可信度信息、第一停放信息，以及第二停放信息，规划源地址与目标地址之间的目标路径；可信度信息用于表征第一停放信息对目标路径的影响程度。信息获取装置在筛选路径时，除了根据第一停放信息之外，还可以根据多个元素选择目标路径，比如道路等级、拥堵状况、收费情况、距离、红绿灯数量、用户个人行驶习惯、用户个人偏好等。因此，若结合第一停放信息的可信度信息，则在选择目标路径时可以更合理的确定各个因素对目标路径的影响程度，从而可以更合理的规划目标路径。
在一种可能地实施方式中，第一停放信息中的可信度信息为以下内容中的至少一项：第一停放信息的生成时间。第一路侧上车辆停放情况的信息的刷新频率，其中，第一路侧上车辆停放情况的信息是周期性刷新的。生成时间距离当前时间越近，则说明第一停放信息与当前第一路侧上车辆停放情况越符合，则可信度越高，反之则越低。第一路侧上车辆停放情况的信息的刷新频率越高，则第一停放信息的可信度越高，说明第一停放信息与当前第一路侧上车辆停放情况越符合，反之则越低。如此，可以看出，若结合第一停放信息的可信度信息，则在选择目标路径时可以更合理的确定各个因素对目标路径的影响程度，从而可以更合理的规划目标路径。
在一种可能地实施方式中，第一停放信息还包括以下内容中的至少一项：停放在第一 路侧的车辆的路面宽度占用信息。如此，可以在路径规划过程中考虑被路侧停放车辆占用一定宽度的道路后，剩余宽度的道路的通行效率，如此，可以更加合理的进行路径规划。
在一种可能地实施方式中，路面宽度占用信息包括：第一路侧上停放车辆所占用的路面宽度。在一种可能地实施方式中，车辆信息还包括：车辆的宽度信息。根据车辆信息，确定第一路侧的第一停放信息，包括：根据第一路侧停放的至少一辆车辆的宽度信息、车辆的位置信息和第一路侧的道路宽度信息，确定第一路侧停放车辆的路面宽度占用信息。如此，可以根据第一路侧单量停放车辆所占据的宽度来确定第一路侧上整体路面宽度被占用的尺寸信息，从而为更加合理的进行路径规划奠定基础。
在一种可能地实施方式中，第一停放信息还包括以下内容中的至少一项：停放在第一路侧的车辆对第一路段的道路的占用程度信息。如此，可以为更加合理的进行路径规划奠定基础。
在一种可能地实施方式中，占用程度信息为以下内容中的一项：重度占用、中度占用、轻度占用或无占用。如此，可以尽量避开重度占用和中度占用的路段，从而可以提高路径规划的合理性。
在一种可能地实施方式中，根据车辆信息，确定第一路侧的第一停放信息，包括：根据车辆信息，统计第一路侧的第一停放车辆数；根据第一停放车辆数或路面宽度占用信息中的至少一项，确定第一停放信息中的占用程度信息。如此提高占用程度信息的计算的合理性和准确性。
在一种可能地实施方式中，占用程度信息满足以下内容中的至少一项：与第一停放车辆数正相关；或，与路面宽度占用信息正相关，其中，路面宽度占用信息用于指示停放在第一路侧的车辆所占据的路面的宽度。如此可以提高占用程度信息的计算的合理性和准确性。
在一种可能地实施方式中，根据数量和路面宽度占用信息，确定占用程度信息，包括以下内容中的一项：根据预设的占用程度信息、路侧长度和车辆数量之间的对应关系，确定第一路侧的长度和第一停放车辆数对应的占用程度信息。如此，可以结合第一路侧长度和停放车辆的数量来确定占用程度信息，可以提高占用程度信息的计算的合理性和准确性。
在一种可能地实施方式中，根据预设的占用程度信息、路段宽度和路面宽度占用信息之间的对应关系，确定第一路段的宽度和路面宽度占用信息对应的占用程度信息。如此，可以结合第一路侧宽度和停放车辆所占用的路面宽度来确定占用程度信息，可以提高占用程度信息的计算的合理性和准确性。
在一种可能地实施方式中，根据预设的占用程度信息、路侧长度、车辆数量、路段宽度和路面宽度占用信息之间的对应关系，确定第一路侧长度、第一路段的宽度和第一停放车辆数和路面宽度占用信息对应的占用程度信息。如此，可以结合第一路侧长度、停放车辆的数量、第一路侧宽度和停放车辆所占用的路面宽度来确定占用程度信息，可以提高占用程度信息的计算的合理性和准确性。
在一种可能地实施方式中，第一路侧包括路侧停车位。第一停放信息包括：第一路侧的停车位信息。由于路侧停车位的信息并不像大型停车场一样有专门的服务器进行管控，因此路侧停车位信息一直以来并未为用户提供，而本申请实施例中可以基于第一路侧上停放的车辆的车辆信息确定第一路侧的停车位信息，进而可以向用户提供第一路侧的停车位信息，或者也可以基于第一路侧的停车位信息规划是否将用户导航至第一路侧的路侧停车 位，从而可以为用户提供更多的停车位的选择。
在一种可能地实施方式中，第一路侧中的第一路侧停车位与目标地址之间的距离小于距离阈值。如此，可以为用户提供距离目标地址较近的路侧停车位信息。
在一种可能地实施方式中，停车位信息包括以下内容中的至少一项：第一路侧中空闲停车位的数量；或，第一路侧中路侧停车位的收费模式。如此，可以给用户提供更多的路侧停车位的相关信息，从而为用户进行更合理的选择奠定基础。
在一种可能地实施方式中，根据车辆信息，确定第一路侧的第一停放信息，包括：根据车辆信息，统计路侧停车位的第二停放车辆数；根据第二停放车辆数，确定停车位信息。如此，可以根据第一路侧的停车位中能停放的车辆总数量，以及当前停放在停车位内的车辆的总数量计算出空余停车位。可见，本申请实施例中可以基于众包车辆所采集到的周围环境信息，分析出路侧停车位信息，不需要专门的服务器进行停车位区域的管控，从而可以节省成本，也可以提高用户的便利性。

具体实施方式
下面结合附图进一步介绍本申请实施例。
图1示例性示出了本申请实施例适用的一种场景的示意图，如图1所示，该场景中可以有一个或多个数据采集装置，还可以包括信息获取装置。数据采集装置可以为终端设备，比如数据采集装置可以为图1中的车辆101、路侧单元102和车辆103，也可以是这些设备中的部件、模块或者芯片等。当数据采集装置为终端设备或为置于终端设备的部件或芯片时，可以通过终端设备的传感器采集道路中的车辆信息。数据采集装置可以直接向信息获取装置上报采集到的第一路侧的车辆信息，也可以通过其他设备向信息获取装置上报该信息，比如可以通过第三方云104向信息获取装置发送该信息。第三方云104可以为其他的服务器或设备。
本申请实施例中信息获取装置可以为终端设备或云端的服务器，或为这些设备中的部件或芯片等，在图1中是以信息获取装置设置于云端的服务器110上为例进行示意的。本申请实施例中的信息获取装置接收到至少一个数据采集装置采集的车辆信息，经统计分析，可以得到第一时间段内第一路段的第一路侧上车辆停放情况的信息，为了描述方便，将第一路段的第一路侧上车辆停放情况的信息称为第一停放信息。
第一停放信息可以用于辅助用户进行智能驾驶。比如可以辅助用户进行路径规划。比如可以将规划的路径下发至用户的电子设备或车辆，以便提供导航服务。电子设备比如可以为图1中的电子设备113(图1中仅仅以智能手机示例，在实际应用中电子设备包括不限于平板电脑、智能手环、智能手表等具有显示屏的设备)。当信息获取装置将规划的路径下发给车辆时，可以由服务器110通过与车辆111之间的通信链路下发，也可以由服务器110先将规划路径发送至路侧单元112，之后由路侧单元112转发至车辆111。如此，可以尽量避开路侧停放车辆较多的路段，可以使通行时间缩短。另一方面，由于路侧停放车辆需占用一定宽度的道路，导致该段道路变窄，较易引发交通事故，因此在规划路径时若避开此类路段，也可以减少交通事故的发生频次。本申请实施例中还可以基于第一路侧上车辆停放情况向用户提供路侧停车位的信息，以便用户在选择停车场时除了考虑大型停车场之外还可以考虑路侧停车场。
如图1所示，本申请实施例中还可以包括有存储设备120，存储设备120可以用于存储数据，比如可以存储本申请实施例中各个数据采集装置上报的车辆信息，或者存储第一路侧的第一停放信息等。
下面分别介绍图1中涉及到的部件以及本申请实施例中涉及到的部分术语。

(2)路侧单元(road side unit，RSU)。
如图1所示，该应用场景中可以包括RSU，RSU可用于通过直接通信(如PC5)或专用短程通信技术(dedicated short range communications，DSRC)等通信方式向终端设备发送车辆到一切(vehicle to everything，V2X)消息。V2X消息可承载动态信息或者其他需要通知终端设备的信息。其中，路侧单元与终端设备之间的通信方式也可被称为车辆与路边基础设施(vehicle to infrastructure，V2I)通信。
路侧单元还可用于与服务器之间通信。路侧单元中也可以设置有数据采集装置。数据采集装置可以将管辖范围内发生的动态信息(例如路侧停放车辆信息)上报至车联网的服务器，如，可以通过路侧信息(roadside information，RSI)消息上报动态信息。
本申请对于路侧单元的具体部署形态不作具体限定，其可以是一个终端设备、移动或非移动的终端设备、服务器或芯片等。
(3)终端设备。

本申请实施例中终端设备可以用于采集周边环境信息，比如可以通过终端设备上设置的传感器采集周边环境信息。本申请实施例中车辆中可以包括数据采集装置。数据采集装置可以通过传感器采集数据，并将通过传感器采集的数据传输给服务器或路侧单元，以使其获取路侧上车辆停放情况的信息。当终端设备为车辆时，本申请实施例中车辆中的数据采集装置可以为车辆内的部件、车辆本身或者手机等。该数据采集装置可以包括该车辆中定位系统的数据采集设备、智能驾驶的数据采集设备或其他任何具有计算能力的设备实施。
本申请实施例中终端设备(比如车辆)上设置有传感器，该传感器用于采集车辆附近的图像，其中，传感器可以包括摄像头、激光雷达、毫米波雷达、超声波等。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。
(4)数据采集装置上报的数据。
本申请实施例中数据采集装置可以上报通过传感器采集到的原始数据，也可以上报对原始数据进行了处理的数据，比如可以上报对原始数据进行护理后得到的特征级数据或目标级数据。本申请实施例中对数据采集装置上报的数据的具体格式不做限制。
当传感器为激光雷达时，原始数据为激光雷达点云数据；当传感器为摄像头时，原始数据为像素级(Pixel Level)数据。原始数据可以表示为Pi(i＝0,1,2…N)，Pi为传感器探测的环境中某一点的信息，N表示传感器探测的环境点数量。如对于三维激光雷达点云而言，Pi表示环境中某点的三维坐标信息，对于摄像头而言，Pi表示环境中某点映射到二维图像中的像素信息。
特征级(Detection Level或者Feature Level)数据为从传感器采集到的原始数据中提取的能够表征被探测物特征的数据。特征，例如可以为某个被探测物形状轮廓的关键点，还可以为环境中通过三维激光点云或图像获得的局部梯度特征等。特征级数据可以表示为 Fi(i＝0,1,2…N)，Fi可以为传感器探测的环境中被探测物的某个特征的信息，N表示被探测物的特征的数量。

为了更容易理解本申请实施例，图2示例性示出了一种车辆通过传感器采集周边环境信息的场景示意图，如图2所示，将地图上的道路划分为至少一个路段，比如图2中示出的第一路段和第二路段。车辆101顶部的中间位置设有激光雷达。车辆101从第一路段经过，则车辆101可以通过激光雷达获取周边的环境信息，继而将环境信息上报至信息获取装置，车辆101还会上报获取该环境信息时该车辆101当前所处的位置的信息。从图2中可以看出，车辆101的激光雷达的扫描区域内有车辆(该车辆可能是停放在路侧的，也可能是在道路上行驶的)或其他物体，车辆101通过激光雷达获取到的环境信息中可以包括有车辆的位置信息、车辆的尺寸信息等。如图2所示，第一路段上还包括摄像头105，该摄像头也可以拍摄摄像头周边的环境信息，并将其上报至信息获取装置。
信息获取装置接收至少一个数据采集装置采集到的第一路段的环境信息，对这些信息进行分析，比如时间聚类分析，从而可以统计出第一路段的第一路侧的车辆停放情况。第一路侧的车辆停放情况可以用于进行路径规划。
基于上述内容，图3示例性示出了本申请实施例提供的一种信息获取方法的流程示意图，该方法可以由信息获取装置来执行。信息获取装置具体实现形式如前，在此不再赘述。如图3所示，该方法包括：
S301，至少一个数据采集装置在第一时间段内采集第一路段的环境信息，并将第一路段的环境信息上报至信息获取装置。图3示出了两个数据采集装置，本申请对数据采集装置的数量不做限制。
一个数据采集装置采集到的第一路段的环境信息中可以包括该数据采集装置周边的车辆信息，还可以包括周边的地图元素的相关信息，地图元素是指地图中的一些元素，包括不限于：道路、车道线、标牌、地面标识、信号灯、可行驶区域标识线等。其中，道路可以包括护栏、路沿等；标牌包括：路标牌、指示性牌、限高牌等各种类型，地面标识包括：分流标识、出入口标识、限速标识、限时标识等。
相对应地，信息获取装置接收至少一个数据采集装置上报的第一路段的环境信息。
本申请实施例中的一个路段是指具有一定长度的道路。本申请实施例中一条路径可以包括一个路段，也可以包括多个路段。当一条路径包括一个路段时，该路段是指该路径的源地址和目标地址之间的道路。当一条路径划分为至少两个路段时，具体划分方式可以有以下多种：
方式一，可以将满足预设长度的一段道路称为一个路段，这种情况下，任意两个路段的长度均为预设长度。
方式二，可以将两个相邻路口之间的道路称为一个路段，这种情况下两个路段的长度可能相等，也可能不相等。如此，可以以相邻两个路口之间的道路上停放车辆对道路的占 用程度，确定该段道路是否需要绕过。
方式三，可以将两个路口之间的道路称为一个路段，该两个路口可以是相邻的路口，也可以是不相邻的两个路口，且可以要求一个路段的长度与预设长度之间的差值的绝对值不大于预设的距离阈值，如此，既可以以路口来划分路段，也可以使每个路段的长度接近预设长度。
一个路段也可以理解为一个空间统计单元，第一对该空间统计单元内的路侧停放车辆进行时间聚类分析，从而得到第一停放信息。
S302，信息获取装置根据至少一个数据采集装置上报的至少一个第一路段的环境信息，获取第一时间段内第一路侧的至少一辆车辆的车辆信息。一辆车辆的车辆信息可以包括该车辆的位置信息，还可以包括该车辆所占据的路面宽度信息。
举个例子，数据采集装置为车辆，该车辆安装有摄像头，当该车辆途径第一路段时，通过摄像头采集道路信息，比如可以拍摄第一路段上的图像，进而车辆可以将通过摄像头拍摄的一张或多种图像以及拍摄的该图像的相关参数(例如拍摄时间、拍摄该图像时车辆的位置信息等)上传至信息获取装置。
信息获取装置根据接收到的至少一辆车辆上报的第一路段的图像，经分析后，可以确定出停放在第一路侧的车辆，针对停放在第一路侧的车辆，信息获取装置可以根据包括有该车辆的图像以及拍摄该图像时数据采集装置的位置信息，确定出该车辆的位置信息。该车辆位置信息可以是在一个坐标系下的一组坐标值，比如可以是在地球坐标系下的一组坐标值，也可以是在车辆坐标系下的一组坐标值。
基于该示例，在又一种可能地实施方式中，针对停放在第一路侧的车辆，信息获取装置可以根据包括有该车辆的图像确定出：车辆的宽度信息。进一步，信息获取装置可以结合该车辆的宽度信息，该车辆的位置信息，以及第一路段的道路宽度信息，确定该车辆所占据的路面宽度。
需要说明的是，本申请实施例中提到的路侧停放车辆是指在道路侧边停放的车辆。当道路侧边未停放车辆时，该道路侧边的道路可以用于通行车辆；而当道路侧边停车车辆后，可用于通行车辆的道路的宽度会变窄。本申请实施例中道路侧边可以设置有停车位，也可以未设置停车位，本申请实施例中的一辆路侧停放车辆可以为停放在路侧的停车位中的车辆，也可以为未停放在路侧的停车位中的车辆(比如由于附近没有停车位，或者由于临时短时间的停车导致的在路侧停车)。
S303，信息获取装置根据第一路侧的至少一辆车辆的车辆信息，确定第一路侧的第一时间段内第一路侧上车辆停放情况的信息。
为了描述方便，本申请实施例中将第一路侧的第一时间段内第一路侧上车辆停放情况的信息称为第一停放信息。第一停放信息可以用于规划源地址与目标地址之间的目标路径。
本申请实施例中的信息获取装置可以周期性或者以不定时长多次刷新第一路侧的车辆停放情况的信息，下面以第一停放信息为例，对本申请实施例生成的第一路侧的车辆停放情况的信息进行介绍。
在一种可能地实施方式中，第一停放信息可以包括以下信息a1至信息a5中的至少一项：
信息a1，第一路侧的标识。
第一路侧的标识可以是地图上对该第一路段的命名，比如道路名称。
在又一种可能地实施方式中，第一路侧的标识还可以是该第一路侧上的某个区域、地点或物体的名称。比如第一路侧上设置有路侧停车位，则第一路侧的标识可以为路侧停车位区域的区域标识。路侧停车位区域的区域标识可以是人为命名的，比如可能是由政府部门命名的，或者也可以有路侧停车位区域的管理者自己命名的。
信息a2，第一路侧的位置信息。
第一路侧的位置信息可以是能够指示出该第一路段的起始位置、终止位置以及所经道路的信息，还可以包括标识第一路侧为第一路段中的哪个路侧的信息(第一路侧可以是指第一路段中的两个路侧，也可以是指第一路段中的两个路侧中的任一个路侧)。举个例子，第一路段为两个路口之间的一段道路，则第一路侧的位置信息可以包括该两个路口的位置信息。
在又一种可能地实施方式中，第一路侧的位置信息还可以是该第一路侧上的某个区域的位置信息，比如第一路侧上设置有路侧停车位，则第一路侧的位置信息可以为第一路侧中的路侧停车位区域的位置信息，比如为路侧停车位区域的两个端点的位置信息。
信息a3，第一时间段。
举个例子，第一路侧上的车辆停放情况的信息可以是周期性刷新的，比如每隔10分钟刷新一次。为了更加与实际情况贴合，刷新的周期可以设置为分钟级别。比如在8点钟生成第一路侧的车辆停放情况的信息，比如可以根据8点至8点10分数据采集装置上报的第一路侧的环境信息进行分析，确定出8点到8点10分第一路侧上车辆停放情况。
信息a4，第一停放信息对应的节假日信息。
第一停放信息对应的节假日信息可以辅助分析第一路侧的停放车辆的规律，以便更好预测第一路侧的车辆停放情况的信息。
第一停放信息的节假日信息可以包括：第一时间段对应的日期是否为工作日的信息，是否为休息日的信息，为周几的信息，是否为国家法定节日的信息，为国家哪个法定节日的信息等等。
信息a5，可信度信息。
可信度信息用于表示第一停放信息的可信程度。可信度信息比如可以以下信息a5-1或信息a5-2中的至少一项。
信息a5-1，第一停放信息的生成时间。
一种可能地实施方式中，当在进行路径规划时，第一停放信息距离当前时刻越近，则推测第一停放信息与第一路侧的实际情况越符合，在进行路径规划过程中被采信的可能性越高。当在进行路径规划时，第一停放信息距离当前时刻越远，则第一停放信息与当前第一路侧的实际情况越不符合，在进行路径规划过程中被采信的可能性越低。
信息a5-2，第一停放信息的刷新频率，其中，第一停放信息是周期性刷新的。
在实际应用中，由于路侧停车具有无序性，一种可能地实施方式中，本申请实施例中第一路侧上车辆停放情况的信息可以是周期性刷新的，刷新频率越高，则该第一停放信息与第一路侧当前实际情况越符合，在进行路径规划过程中被采信的可能性越高。刷新频率越低，则推测该第一停放信息与第一路侧当前实际情况越不符合，在进行路径规划过程中被采信的可能性越低。
在又一种可能地实施方式中，第一停放信息还可以包括以下信息b1或信息b2中的至少一项：
信息b1，停放在第一路侧的车辆的路面宽度占用信息。
路面宽度占用信息用于指示停放在第一路侧的车辆所占据的路面的宽度。
举个例子，针对停放在第一路侧的一辆车辆，信息获取装置可以根据包括有该车辆的图像确定出车辆的宽度信息。进一步，信息获取装置可以结合该车辆的宽度信息，该车辆的位置信息，以及第一路段的道路宽度信息，确定该车辆所占据的路面宽度。
进一步，信息获取装置根据第一路侧上至少一辆车辆所占据的路面宽度，确定路面宽度占用信息。比如，第一路侧停放3辆车辆，该3辆车辆所占据的路面宽度分别为2米、1.8米和1.8米，则可以选择占据路面宽度最大的值作为路面宽度占用信息，也可以选择在该3个路面宽度中占比最大的1.8米作为路面宽度占用信息，也可以选择在该3个路面宽度的平均值作为路面宽度占用信息。
又一种可能地实施方式中，路面宽度占用信息还可以用于指示第一路段上剩余的可以用于通行的道路的路面的宽度，比如可以从第一路段上可以用于通行的道路的路面总宽度减去两个路侧被停放车辆占据的路面的宽度，得到的值可以为路面宽度占用信息。
需要说明的是，本申请实施例中第一路侧是指第一路段中的路侧，可以是指第一路段中的两个路侧，第一路侧车辆的路面宽度占用信息可以包括第一路段中两个路侧上停放的车辆所占用的路面总宽度。或者第一路侧是指第一路段上两个路侧中的任一个路侧，这种情况下第一路侧车辆的路面宽度占用信息可以包括第一路段中第一路侧上停放的车辆所占用的路面宽度。
信息b2，停放在第一路侧的车辆对第一路段的道路的占用程度信息。
举个例子，可以预先设置几个占用程度信息，比如可以根据占用程度从低到高的顺序，依次设置：无占用、轻度占用、中度占用和重度占用。可以根据如下内容中的至少一项确定路侧停放车辆对第一路侧的道路的占用程度信息：
第一路侧停放车辆的数量(可以称为第一停放车辆数，可以根据车辆信息统计得到)、第一路侧的长度、第一路段的宽度，或路面宽度占用信息。
下面针对如何确定占用程度信息举几个示例：
示例一，设置路侧停放车辆的数量与占用程度信息的对应关系，之后根据该对应关系，以及第一路侧停放车辆的数量，确定出对应的路侧停放车辆对道路的占用程度信息。路侧停放车辆的数量与占用程度信息之间可以是正相关，即路侧停放车辆的数量越多，则该路段上路侧停放车辆对道路的占用程度越高。
需要说明的是，本申请实施例中第一路侧可以是指第一路段中的两个路侧，这种情况下第一路侧停放车辆的数量可以理解为在第一路段中的两个路侧停放的车辆的总数量。或者第一路侧是指第一路段上两个路侧中的任一个路侧，这种情况下第一路侧停放车辆的数量可以理解为在第一路段中的第一路侧停放的车辆的总数量。
示例二，设置路侧停放车辆的数量、路段长度(或者称为路侧长度)与占用程度信息这三者之间的关联关系，之后根据该关联关系，以及第一路侧停放车辆的数量和第一路侧的长度，确定出对应的路侧停放车辆对道路的占用程度信息。路侧停放车辆的数量和路段长度之间的比值与占用程度信息之间可以是正相关。
这种情况下，当两个路段的长度不同时，若该两个路段上路侧停放车辆的数量基本相等，则可能确定出两个不同的路侧停放车辆对道路的占用程度信息。举个例子，以相邻两个路口之间的道路称为一个路段，且一个路段的长度为另一个路段的长度的两倍，两个路段的路侧停放相同数量的车辆，这种情况下，长度较长的路段的路侧的停放车辆对该路段的占用程度信息可能为轻度占用，长度较短的路段的路侧的停放车辆对该路段的占用程度信息可能为中度占用。
示例三，设置路面宽度占用信息与占用程度信息的对应关系，之后根据该对应关系，以及第一路侧的路面宽度占用信息，确定出对应的占用程度信息。路面宽度占用信息可以指示出第一路侧停放车辆占据的路面宽度，该尺寸与占用程度信息之间可以是正相关，即第一路侧停放车辆占据的路面宽度越宽，则该路段上路侧停放车辆对道路的占用程度越高，反正则越低。
示例四，设置路面宽度占用信息、路段宽度与占用程度信息的对应关系，之后根据该对应关系，以及第一路侧的路面宽度占用信息和第一路段的宽度，确定出对应的占用程度信息。路面宽度占用信息和第一路段的宽度可以指示出第一路段剩余的可用于行驶车辆的路面宽度，该尺寸与占用程度信息之间可以是反相关，即剩余的可用于行驶车辆的路面宽度越宽，则该路段上路侧停放车辆对道路的占用程度越低，反正则越高。
示例五，设置路侧停放车辆的数量、路段长度(或者称为路侧长度)、路段宽度、路面宽度占用信息与占用程度信息之间的关联关系，之后根据该关联关系，以及第一路侧停放车辆的数量、第一路侧的长度、第一路段的宽度和第一路侧的路面宽度占用信息，确定出对应的占用程度信息。
在又一种可能地实施方式中，第一路侧包括路侧停车位，这种情况下，第一停放信息还可以包括以下信息c1：第一路侧的停车位信息。
信息c1可以包括以下信息c1-1或信息c2-2中的至少一项：
信息c1-1，第一路侧中空闲停车位的数量。
在一种可能地实施方式中，第一路侧的路侧停车位可能包括有停车位的标识线，也有可能没有停车位的标识线。当有停车位的标识线的时候，可以从数据采集装置上报的环境信息中识别出路侧的停车位是被占用还是空闲。进而可以统计出第一路侧中空闲停车位的数量。
又一种可能地实施方式中，可以根据第一路侧的停车位的总数量，以及当前第一路侧的停车位区域停放的车辆的总数量，可以称为第二停放车辆数，计算第一路侧中空闲停车位的数量。第一路侧的停车位的总数量可以是预设的，或者可以根据第一路侧的长度计算。
由于路侧停车位的信息并不像大型停车场一样有专门的服务器进行管控，因此路侧停车位信息一直以来并未为用户提供，而本申请实施例中基于数据采集装置上报的信息，可以生成第一路侧的停车位信息并向用户提供，从而可以为用户提供更多的停车位的选择，提高用户的便利性。
信息c1-2，第一路侧中路侧停车位的收费模式。
可选地，信息c1还可以包括其他信息，比如路侧停车位区域中停车位总数量，路侧停车位区域当前停放车辆数量的原因说明。举个例子，该路侧停车位区域位于学校附近，该时间段内该路侧停车位区域中的所有停车位全部为空闲停车位，可以添加原因说明，比如 为寒假期间。
在一种可能地实施方式中，当第一路侧包括路侧停车位，则第一停车信息可以用于辅助用户选择停车场，这种情况下，第一停放信息可以包括前述信息a1、信息a2、信息a3、信息a4、信息a5或信息c1中的至少一项。
S304，信息获取装置可以根据第一停放信息、预测的第二时间段内的第二停放信息，或预存的至少一个第三停放信息中的至少一项，规划源地址与目标地址之间的目标路径。
本申请实施例中第一停放信息和第二停放信息均是第一路侧上车辆停放情况的信息，区别为：第一停放信息为当前获取到的最新的第一路侧上车辆停放情况的信息。而第二停放信息是预测的第二时间段内第一路侧上车辆停放情况的信息。第二时间段的时间起始点晚于第一时间段的时间起始点。第三停放信息可以为在获取第一停放信息之前所获取到的第一路侧上车辆停放情况的信息，也可以为预设的第一路侧上车辆停放情况的信息，比如可以是根据以往经验预设的第一路侧上车辆停放情况的信息，或者是根据历史数据预设的第一路侧上车辆停放情况的信息。
本申请实施例中，第二停放信息可以根据第一停放信息或预存的至少一个第三停放信息中的至少一个预测。下面介绍几种可能的预测第二停放信息的示例。
示例d1，预测的第二停放信息中的占用程度信息为：一个第三停放信息中的占用程度信息。
举个例子，昨天在第二时间段(示例地，下午5：00到7:00)内第一路段的占用程度为重度占用。可以预测今天未来第二时间段(示例地，下午5：00到7:00)内路侧停放车辆对第一路段的占用程度也为重度占用。
再举个例子，当昨天在第二时间段内第一路侧的空闲停车位数量为5个。可以预测今天未来第二时间段内第一路侧的空闲停车位数量为5个。
在又一种可能地实施方式中，第三停放信息为历史的第二时间段内第一路侧上车辆停放情况的信息，如此，可以提高预测的第二停放信息的准确性。举个例子，第一时间段为7：50-8点，第二时间段为8：50-9点，则第一停放信息为今天7：50-8点对应的第一路侧上车辆停放情况的信息。第二停放信息为预测的今天8：50-9点对应的第一路侧上车辆停放情况的信息。第三停放信息为过去至少一天中每天8：50-9点对应的第一路侧上车辆停放情况的信息。
需要说明的是，本申请实施例中涉及到时间段的定义，比如第一时间段和第二时间段可以相等也可以不相等，不做具体限制。第一时间段和第二时间段中的任一个时间段的实际长度可以自行定义，比如可以是几分钟，也可以是几个小时，对此不进行限制。
示例d2，第二停放信息中的占用程度信息为：多个第三停放信息中的占用程度信息中：占比最大的一个。
举个例子，获取昨天、前天和大前天的第二时间段对应的三个第三停放信息，该三个信息分别指示停放车辆对第一路段的占用程度依次为重度占用、重度占用和中度占用。由于重度占用占了三分之二，因此可以预测今天未来第二时间段内路侧停放车辆对第一路段的占用程度也为重度占用。
再举个例子，获取昨天、前天和大前天的第二时间段对应的三个第三停放信息，该三个信息分别指示第一路侧的空闲停车位数量依次为5、5和10。由于5占用占了三分之二， 因此可以预测今天未来第二时间段内第一路侧的空闲停车位数量为5。
在又一种可能地实施方式中，预测未来的第二停放信息的空闲停车位数量可以为：多个第三停放信息中的空闲停车位数量的平均值，或者为加权相加后的值。比如可以依据各个历史的第三停放信息生成的日期的新旧程度，为各个第三停放信息确定权重。其中，日期越新，则第三停放信息的权重可以越大。第三停放信息的权重用于表征其对第二停放信息中的空闲停车位数量的影响程度。
示例d3，在一种可能地实施方式中，第一停放信息还包括：第一停放信息对应的节假日信息。预存的至少一个第三停放信息对应的节假日信息与第一停放信息对应的节假日信息匹配。如此，可以依据第一路段的节假日的路侧停放车辆的规律，预测未来的第二时间段内第一路侧上车辆停放情况的信息，从而提高预测的第二停放信息的准确性。
举个例子，今天为周六，则可以依据过去的多个周六中第二时间段对应的第三停放信息预测。比如，可以将该多个周六中第二时间段对应的多个第三停放信息中的占用程度信息中占比最大的作为：第二停放信息中的占用程度信息。
再举个例子，今天为周六，则可以依据过去的多个周六中第二时间段对应的第三停放信息预测。比如，可以将该多个周六中第二时间段对应的多个第三停放信息中的第一路侧的空闲停车位数量中占比最大的作为：第二停放信息中的第一路侧的空闲停车位数量。
示例d4，结合第一停放信息和至少一个第三停放信息，预测第二停放信息。
可以为第一停放信息和第三停放信息设置对应的权重，从而对第一停放信息和第三停放信息中的占用程度进行加权相加的计算，从而可以得到预测的第二停放信息中的占用程度。再比如，可以对第一停放信息和第三停放信息中的空闲停车位数量进行加权相加的计算，从而可以得到预测的第二停放信息中的空闲停车位数量。
需要说明的是，预测的第二停放信息中包括的内容可以参见前述第一停放信息包括的内容，在此不再赘述。预测的第二停放信息中可以不携带上述可靠性信息。
本申请实施例中第一路侧上车辆停放情况的信息可以有多种应用场景，比如以下应用场景1和应用场景2。其中，应用场景1中是结合第一停放信息、第二停放信息或第三停放信息中的至少一项规划目标路径。应用场景2中是结合第一停放信息、第二停放信息或第三停放信息中至少一项为用户提供停车位信息。下面分别进行介绍。
应用场景1，结合第一停放信息、第二停放信息或第三停放信息中的至少一项规划目标路径。
下面通过几个示例介绍几种规划路径的方案。
示例e1，根据第一停放信息和第三停放信息规划目标路径。
举个例子，比如获取了10个第三停放信息，其中9个第三停放信息中占用程度信息为重度占用，而1个第三停放信息以及第一停放信息中占用程度信息为轻度占用。这种情况下，由于在该11个中有9个均指示第一路段被占用程度较为严重，占十一分之九，占比最大，因此可以判断该第一路段属于经常被占用的路段，如此，可以尽量避开第一路段，即不选择包括有第一路段的路径作为目标路径。由于本申请实施例中目标路径可以是作为优先级较高的路径推荐给用户的，用户选择使用的可能性较高，而未作为目标路径的其他路径优先级较低，因此用户选择的可能性较低。因此，该示例中，由于包括有第一路段的路径被筛除，并未作为目标路径，因此可以使用户尽量避开第一路段。
在一种可能地实施方式中，第二时间段中的一个时刻为沿第一路径从源地址出发行驶至第一路侧的时刻。比如，从源地址行驶至目标地址包括至少两条路径，第一路径为至少两条路径中包括有第一路段的路径。第二时间段可以为从源地址出发，沿第一路径行驶，途径第一路段的时间段。比如，第二时间段中的一个时刻为沿第一路径从源地址出发行驶至第一路段的时刻。
举个例子，若当前时间为上午9点15分，而若从源地址出发，沿第一路径行驶至第一路段需花费25分钟左右，则预计到达第一路段的时间为9点40分，则第二时间段可以为9点40分至9点50分。由于可以根据历史的第二时间段内对应的第三停放信息，以及第一停放信息去评估是否决策是否需要避开包括有第一路段的路径，进而可以提高路径规划的准确性。
需要说明的是，由于第三停放信息为过去所生成的第一路侧上车辆停放情况的信息，因此，第三停放信息中包括的内容可以参见上述关于第一停放信息的相关描述。
示例e2，根据第一停放信息和第二停放信息规划目标路径。
在一种可能地实施方式中，可以为第一停放信息和第二停放信息设置对应的权重，对其进行加权融合，继而根据结果判定是否需要避开第一路段。第一停放信息的权重用于表征第一停放信息对结果的影响程度，第二停放信息的权重用于表征第二停放信息对结果的影响程度。
在一种可能地实施方式中，可以根据第一路段历史的第三停放信息对权重进行设置，比如第一路段的第三停放信息显示出第一路段上停放车辆具有很强的规律性，则可以将第二停放信息的权重设置为较大值。若第一路段的第三停放信息显示出第一路段上停放车辆并无规律性，或者规律性很不明显，也可以说具有很强的随机性，则可以将第一停放信息的权重设置为较大值。
在又一种可能地实施方式中，可以使第一停放信息和第二停放信息的权重可调。比如可以根据可信度信息调整。可信度信息用于表征第一停放信息对目标路径的影响程度。举个例子，若第一停放信息可信度信息指示第一停放信息的可信度较低，比如刷新频率较低，和/或生成时间距离当前时间较远，则可以将第一停放信息的权重调低，相对应地，由于该两个权重之和是固定的，比如为1，因此第二停放信息的权重对应调高。而若第一停放信息的刷新频率较高，和/或生成时间距离当前时间较近，则可以将第一停放信息的权重调高，相对应地，第二停放信息的权重对应调低。
举个例子，第一停放信息的权重为70％，第二停放信息的权重为30％，第一停放信息指示在第一时间段内路侧停放车辆对第一路段的占用程度为轻度占用，第二停放信息指示在预测在未来的第二时间段内路侧停放车辆对第一路段的占用程度为重度占用。由于轻度占用的权重为70％，因此在筛选目标路径时，可以无需避开第一路段，即在其他因素也合适的情况下，也可以将包括有第一路段的第一路径做为目标路径。
再举个例子，比如第一停放信息的生成日期较为久远，比如为5个小时之前所生成的，由于路侧停放车辆具有无序性，因此5个小时之前的第一停放信息与未来第二时间段内第一路段的实际情况符合的可能性较低，因此可以将第一停放信息的权重调低，比如将第一停放信息的权重从70％调低为20％，第二停放信息的权重从30％调高至80％。之后可以根据更新后的权重以及第一停放信息和第二停放信息进行路径规划。
除了上述两种示例之外，还有其他方式规划目标路径，比如根据第一停放信息、第二 停放信息和第三停放信息规划目标路径。这种实施方式中，可以为各个停放信息分别设置对应的权重，从而综合考虑是否需要避开第一路段。该方式中的相关内容可以参见前述方案，此处不再赘述。
通过上述方案，在对路径筛选时，可以尽量选择路侧未停放车辆，或者路侧停放车辆对道路的占用程度较轻的路段，可以尽量避开路侧停放车辆较多的路段，从而可以使通行时间缩短，进而可以提高通行效率。另一方面，由于路侧停放车辆需占用一定宽度的道路，导致该段道路变窄，较易引发交通事故，因此在规划路径时若避开此类路段，也可以减少交通事故的发生频次。
信息获取装置在筛选路径时，除了根据第一停放信息之外，还可以根据以下元素中的一项或多项进行选择，从而选择出更加合理的目标路径：
道路等级、拥堵状况、收费情况、距离、红绿灯数量、用户个人行驶习惯、用户个人偏好等。
通过上述内容可以看出，本申请实施例中可以提供地图上路段的路侧上车辆停放情况的信息，该信息为动态可变的，也可以称为路侧停放车辆的动态信息(或者称为路侧停车车辆的动态信息模型)。本申请实施例中，可以构建路侧停放车辆的动态信息模型，进而可以生成路侧停放车辆的动态图层(该图层中包括有最近刷新的第一路侧的第一停放信息)，同时可以生成路侧停放车辆的预测图层(该图层中包括有预测的路段的第二停放信息)，在进行路径规划时，可以将最近刷新的路段的第一停放信息和预测的路段的第二停放信息作为两个输入，优先选择路侧未停车和路侧停放车辆较少的路段，从而可以使用户尽量避开被路侧停车车辆占用较为严重的路段。
应用场景2，结合第一停放信息、第二停放信息或第三停放信息向用户提供路侧停车位信息。
第一停放信息包括第一时间段内第一路侧的停车位信息。第二停放信息也包括第一路侧的停车位信息，而第二停放信息为预设的。第三停放信息也包括第一路侧的停车位信息，但第三停放信息为预测的未来的第二时间段内的第一路侧的停车位信息。第二时间段中的一个时刻可以为从源地址出发行驶至第一路侧的一个时刻。
本申请实施例中，当用户输入目标地址，也可以将用户当期位置作为目标地址，则可以对应提供目标地址附近的路侧的停车位信息。比如第一路侧的停车位为目标地址附近的停车位，第一路侧的一个停车位为与目标地址之间的距离小于预设的距离阈值。则可以向用户提供第一停放信息、第二停放信息或第三停放信息中的至少一项，以便用户决定是否将车辆停至第一路侧的路侧停车位。如此，相比于仅提供非路侧停车位信息的方案，本申请实施例中还可以提供路侧停车位信息，因此可以提高用户的便利性。
在又一种可能地实施方式中，信息获取装置可以根据第一停放信息、第二停放信息或第三停放信息中的至少一项确定是否将车辆导航至该路侧停车位区域。在一种可能地实施方式中，可以设置对应权重，继而根据各项对应的权重，对各项信息中的空闲停车位的数量进行加权相加，得到的结果如果大于预设的数量阈值，则可以将车辆导航至该路侧停车位区域，比如将该路侧停车位区域设置为目标路径中的一个途径点，或者也可以将该路侧停车位区域作为新的目标地址，以更新原有目标地址，当用户达到路侧停车位区域后，则重新基于用户的位置和原有的目标地址为用户规划步行路径。
通过上述内容可以看出，本申请实施例中可以提供地图上路段的路侧停车位信息，该信息为动态可变的，也可以称为路侧停车位的动态信息(或者称为路侧停车位的动态信息模型)。本申请实施例中，可以构建路侧停车位的动态信息模型，进而可以生成路侧停车位信息的动态图层，同时可以生成路侧停车位信息的预测图层，在进行路径规划时，可以将最近刷新的路段的第一停放信息中的停车位信息、第二停放信息中的停车位信息或第三停放信息中的停车位信息中的至少一项作为输入，以便当该路侧停车位在第二时间段内存在较多空闲停车位时，可以将车辆导航至该路侧停车位区域。由于可以对车辆进行提前诱导，因此也可以提高城市通行效率和停车效率。且另一方面，也可以发送第一停放信息、第二停放信息或第三停放信息中的至少一项，以使用户自行抉择是否行驶至路侧停车位区域以便进行停车。第三方面，路侧停车位信息的动态图层和路侧停车位信息的预测图层还可以为作为城市管理和城市路侧停车位区域规划的重要参考。
本申请实施例中的术语“系统”和“网络”可被互换使用。“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。
以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一停放信息和第二停放信息，只是为了区分不同的停放信息，而并不是表示这两个车辆的优先级或者重要程度等的不同。
