图5是根据本申请一些实施例所示的指示箭头的显示方法500的示例性 流程图。
在一些实施例中，该指示箭头的显示方法500可以由服务请求者终端130、服务提供者终端140或移动设备300等具有处理、运算能力的设备执行。相应的，指示箭头的显示系统400可以为服务请求者终端130、服务提供者终端140或移动设备300中的硬件、软件或者软件和硬件的结合。
在一些实施例中，该指示箭头的显示方法500还可以由服务器110或计算设备200等具有处理、运算能力的设备执行。相应的，指示箭头的显示系统400可以为服务器110或计算设备200中的硬件、软件或者软件和硬件的结合。
如图5所示，该指示箭头的显示方法500可以包括：
步骤510，获取导航路线中至少一个指示箭头信息。具体的，步骤510可以由获取模块410执行。
导航路线可以为用户终端(即，服务请求者终端130或/和服务提供者终端140)上指示该用户终端所在车辆行驶的路线。用户终端获取到用户输入的起点和终点后，可以接收服务器110下发的导航路线后进入导航状态。
导航路线上可以包括引导车辆进行道路转换的一系列指示箭头。道路转换可以为车辆从一条道路行驶到另一条道路，例如，路口转弯、主辅路变道或掉头等。由于导航路线上的道路转换形式不同，因此可以包括一系列不同的指示箭头。在一些实施例中，如图6所示，指示箭头至少可以包括以下一种：左转箭头、右转箭头、直行箭头、掉头转向箭头、环形行驶箭头、连续转向箭头、左前方行驶箭头或右前方行驶箭头。左转箭头可以包括左直角转弯箭头、左斜转弯箭头。右转箭头可以包括右直角转弯箭头、右斜转弯箭头。连续转向箭头可以包括距离较近的两个或以上转弯路口的指示箭头。左前方行驶箭头可以包括从辅道行驶到主道的指示箭头。右前方行驶箭头可以包括从主道行驶到辅道的指示箭头。
在一些实施例中，指示箭头信息可以包括指示箭头所对应的道路转换位置的坐标数据。该坐标数据与该道路转换位置的经纬度相对应。指示箭头信息可 以包括表征指示箭头的至少一组点集(或称为拓扑点)。如图7所示，指示箭头701可以包括一组点集702(图7中的虚线方块)，该一组点集702形成指示箭头的形状和方向，用户通过观察指示箭头的方向以驾驶车辆。
在一些实施例中，指示箭头可以包括3D指示箭头、2.5D指示箭头或2D指示箭头。若以2D指示箭头作为转弯或变道的指示标志，在复杂道路转换时可能无法准确作出提示，而且视觉效果较差，可能使用户行驶在错误的车道上，给用户带来了诸多不便。由于3D指示箭头相较2D和2.5D指示箭头具有一定的厚度，且给用户更加直观的观感，因此，指示箭头为3D指示箭头时，可以使用户更加直观地观察到前方道路的变化。
在一些实施例中，如图9所示，指示箭头为3D指示箭头，该3D指示箭头具有一定的厚度，如图9所示的标记910，即表示3D指示箭头的厚度。图10为图9的3D指示箭头在2D视角下的从屏幕正上方俯视的示意图(或在屏幕中的正投影图)。如图10所示，标记1010表示指示箭头的头部箭头的宽度、标记1020表示指示箭头的头部箭头的高度以及标记1030表示指示箭头的宽度。在2D视角下(即从屏幕正上方俯视3D箭头)，3D指示箭头的头部箭头的宽度(如图10标记1010)、头部箭头的高度(如图10标记1020)及3D指示箭头的宽度(如图10标记1030)、3D指示箭头的厚度(如图9标记910)可以保持一定的比例。该比例可以为便于用户观察且视觉效果较好的比例，仅作为示例，该比例可以为58：44：32：8。以该比例为基准，用户在缩放导航地图时，使得指示箭头在不同的比例尺下可以实现等比例适配。在一些实施例中，若指示箭头为2D指示箭头，2D指示箭头的头部箭头的宽度(如图10标记1010)、头部箭头的高度(如图10标记1020)及2D指示箭头的宽度(如图10标记1030)也可以保持一定的比例，以该比例为基准，用户在缩放导航地图时，使得指示箭头在不同的比例尺下可以实现等比例适配。在一些实施例中，为了不覆盖导航路线且便于用户观察，指示箭头距底图(即屏幕中显示的二维地图)可以保持一定的像素，例如，指示箭头距离底图7个像素。
在一些实施例中，获取模块410可以获取道路转换信息，以获取导航路线中至少一个指示箭头信息。具体的，可以获取至少一个道路转换信息，然后可以基于该至少一个道路转换信息，生成至少一个道路转换信息对应的指示箭头。道路转换信息可以包括路口形状、路口的位置信息、路口的转向角度信息、是否掉头、是否直行、是否变道等信息。至少一个指示箭头可以包括导航路线上下一个道路转换信息对应的指示箭头。获取模块410可以获取至少一个道路转换信息，然后根据道路转换处的至少两条道路的形状，绘制出该道路转换处的至少一个指示箭头。
下面以图8中向左前方行驶的道路作为示例进行说明，获取模块410可以基于当前道路和即将驶入的道路计算出两条道路的转弯角度，进一步地，可以基于该转弯角度和两条道路在导航地图上的位置信息，绘制出针对该向左前方行驶的指示箭头(如图8中的指示箭头801)，指示箭头的形状与向左前方转弯道路的形状相似。
步骤520，基于至少一个指示箭头信息，确定屏幕中指示箭头的最高点。具体的，步骤520可以由第一确定模块420执行。
屏幕可以包括显示导航路线的终端设备，例如，用户终端或与用户终端连接的投影设备。在一些实施例中，指示箭头的最高点可以为指示箭头所在屏幕竖直方向上的最高点。
在一些实施例中，第一确定模块420可以通过在屏幕中建立直角坐标系，然后确定指示箭头中纵坐标值最大的点作为指示箭头的最高点。具体的，可以在屏幕中建立直角坐标系，横轴为屏幕的水平方向，纵轴为屏幕的竖直方向；然后可以基于该直角坐标系，确定该指示箭头中一组点集的坐标值；进而可以确定该一组点集中纵坐标值最大的点，并将该纵坐标值最大的点作为该指示箭头的最高点。
下面以手机屏幕作为示例进行说明，图7为基于屏幕建立直角坐标系的示意图。在一些实施例中，指示箭头中的一组点集在手机屏幕中的坐标为(X， Y)，单位为像素。例如，如图7所示，第一确定模块420可以将屏幕的左下角作为原点O，横轴(x轴)为屏幕的水平方向，纵轴(y轴)为屏幕的竖直方向。第一确定模块420可以根据该直角坐标系，确定指示箭头中的一组点集的坐标值。该坐标值表示点集在屏幕中的像素点的位置。例如，手机屏幕的分辨率为1280×720，则手机屏幕的y轴方向存在1280个像素点，手机屏幕的x轴方向存在720个像素点。原点坐标值为(0,0)，手机屏幕的右上角的坐标值为(720,1280)。如图7所示，指示箭头701由一组点集702(图7中的虚线方块)组成，指示箭头中的一组点集中纵坐标最大的点为图7中的虚线圈所示的点703，即手机屏幕竖直方向(y轴)上的最高点。
在一些实施例中，指示箭头进入屏幕中，按照上述方法，第一确定模块420可以基于至少一个指示箭头信息，确定出指示箭头在屏幕竖直方向上的最高点。
步骤530，将最高点放置于屏幕的预设位置，进而确定指示箭头在屏幕中的显示位置。具体的，步骤530可以由第二确定模块430执行。
预设位置可以为根据用户的观看习惯或视觉效果预先设置的显示位置，该预设位置可以为屏幕中便于用户观察的舒适位置。在一些实施例中，预设位置可以为与屏幕正上方距离为第一像素阈值的直线(如，图8中上报按钮805下方的虚线804)或区域(如，图8中竖直中心线附近一定面积的区域)。屏幕正上方可以为屏幕竖直方向的最高位置，仍以步骤520中的手机屏幕为例，屏幕正上方可以为y＝1280的直线。在一些实施例中，第一像素阈值可以是系统的默认值，例如，100个像素值、150个像素值或200个像素值，也可以根据不同情况进行调整。
在一些实施例中，第二确定模块430可以基于车辆标识在屏幕中的显示位置(如，图8中的车辆标识803)，将最高点放置于屏幕的预设位置以确定指示箭头在屏幕中的显示位置。具体的，可以获取车辆标识在屏幕中的显示位置，然后可以基于车辆标识在屏幕中的显示位置，通过缩放导航地图将指示箭头的最高点放置于屏幕中的预设位置，进而确定指示箭头在屏幕中的显示位置。
在一些实施例中，车辆标识在屏幕中的显示位置可以保持不变，例如，车辆标识可以显示在屏幕的中心点、靠近屏幕竖直中心线下方的某个点等位置。在一些实施例中，第二确定模块430可以先固定车辆标识在屏幕中的显示位置，然后通过缩放导航地图将确定出的指示箭头的最高点放置于预设位置，进而可以确定指示箭头在屏幕中的显示位置。
下面以手机屏幕中指示箭头的显示位置作为示例进行说明，如图8所示，车辆标识(即车辆的当前位置)在屏幕中的位置可以保持不变(如，在手机屏幕竖直中心线下方的某个点803处)，当缩放导航地图时，导航地图范围将以车辆标识为中心进行放大或缩小，在缩放的同时，指示箭头的最高点的位置也会随之发生移动。例如，当放大导航地图时，指示箭头的最高点将远离车辆标识(例如，可能超出屏幕显示范围)，当缩小导航地图时，指示箭头的最高点将靠近车辆标识(例如，从屏幕显示范围外进入屏幕显示范围内)。因此，可以通过尝试缩放导航地图到适当的比例尺以使得指示箭头的最高点(如，图8中指示箭头中的点802)恰好位于屏幕中的预设位置(例如，与图8中的虚线804对齐)。当导航地图发生旋转时，指示箭头的最高点也会发生变化，改变后的最高点依然被放置在预设位置(例如，与虚线804对齐)，从而不会出现指示箭头超出导航界面、或者在屏幕中的位置太靠下的情形，改善了视觉效果。
在一些实施例中，车辆标识的位置在屏幕中的位置可以改变，通过缩放导航地图将确定出的指示箭头的最高点(例如，图8中指示箭头中的点802)与预设位置(例如，图8中的虚线804)对齐时，当车辆标识的位置在屏幕中的位置发生变化时，最高点放置的位置可能也会跟着发生变化，但是最高点仍然与预设位置(例如，图8中的虚线804)对齐。例如，当车辆标识向左移动时，则最高点放置的位置也向左发生移动，进而指示箭头的位置也向左发生偏移。可以理解，当车辆标识的位置在屏幕中的位置发生变化时，图8中指示箭头中的最高点放置的位置可能也会跟着发生变化，但是最高点的位置仅在图8中的虚线804上左右移动。
步骤540，在屏幕中显示指示箭头。具体的，步骤540可以由显示模块440执行。
在一些实施例中，显示模块440可以在屏幕中显示指示箭头。具体的，可以确定出将最高点放置于屏幕的预设位置时导航地图的比例尺，然后判断该比例尺是否在预设范围内：若是，则在屏幕中显示该指示箭头；若否，则在屏幕中不显示该指示箭头。在一些实施例中，预设范围可以包括15～19级，该预设范围也可以根据不同情况进行调整，在此不作限制。
由于将确定出的指示箭头的最高点放置于屏幕中的预设位置是通过缩放导航地图实现的。因此，当缩放导航地图时，导航地图的比例尺也随之发生变化。当缩放导航地图使得指示箭头的最高点恰好处于屏幕中的预设位置时，显示模块440可以记录此时导航地图的比例尺。
仅作为示例说明，显示模块440判断出此时导航地图的比例尺(例如，16级)大于15级时，则显示模块440可以在屏幕中显示指示箭头。反之，当显示模块440判断出此时导航地图的比例尺(例如，14级)小于15级时，显示模块440在屏幕中不显示指示箭头，即用户在屏幕中观察不到指示箭头。随着车辆向前行驶，导航地图的比例尺发生变化，并且直到导航地图的比例尺达到15级时，显示模块440才会在屏幕中显示指示箭头。
在一些实施例中，在比例尺大于或等于15级时显示指示箭头，在导航过程中比例尺动态改变时，可以随时判断比例尺是否满足显示指示箭头的要求。在一个实施例中，在导航界面上原比例尺大于或等于15级(如，17级)时，在屏幕中显示了指示箭头，若此时用户人为(例如，通过缩放手势或点击缩放控件)将比例尺缩小到15级以下(如，13级)，则不再显示指示箭头。在一个实施例中，在导航界面上原比例尺小于15级(如，13级)，在屏幕中不显示指示箭头，若此时用户人为(例如，通过缩放手势或点击缩放控件)将比例尺放大到大于或等于15级(如，17级)，则会显示指示箭头。在一个实施例中，导航界面可以包括全屏导航界面或非全屏导航界面。
在一些实施例中，显示模块440还可以确定指示箭头的宽度并按该宽度进行显示。具体的，可以获取指示箭头所在道路的道路宽度，然后基于该道路宽度和该导航界面上比例尺，确定指示箭头的宽度(如图10标记1030)，进而在屏幕中按该宽度显示指示箭头。
在一些实施例中，指示箭头的宽度可以通过公式(1)和(2)计算得到：
W Arrow＝W Line×w         (1)
Figure PCTCN2020084105-appb-000001
其中，W Arrow为指示箭头的宽度，W Line为指示箭头所对应道路的道路宽度，lev为当前导航界面上的比例尺，20.0f为比例尺的最大级别，k为微量调整参数(如，k＝0.8)。
在一些实施例中，若指示箭头为3D指示箭头，显示模块440可以基于指示箭头的宽度，然后根据步骤510中指示箭头的头部箭头的宽度、头部箭头的高度、指示箭头的宽度和指示箭头的厚度的比例来确定该3D指示箭头的尺寸，进而可以在屏幕中显示该指示箭头。
在一些实施例中，若指示箭头为2D指示箭头，显示模块440可以基于指示箭头的宽度，然后根据步骤510中指示箭头的头部箭头的宽度、头部箭头的高度和指示箭头的宽度的比例来确定该2D指示箭头的尺寸，进而可以在屏幕中显示该指示箭头。
应当注意的是，上述有关流程500的描述仅仅是为了示例和说明，而不限定本申请的适用范围。对于本领域技术人员来说，在本申请的指导下可以对流程500进行各种修正和改变。然而，这些修正和改变仍在本申请的范围之内。例如，500。例如，第一像素阈值的和预设范围不限于流程500中列举的数值，还可以为其他值。
本申请实施例可能带来的有益效果包括但不限于：通过将车辆行驶过程中下一个道路转换位置的指示箭头的最高点放置在屏幕的预设位置(例如，最佳显示位置)，可以使指示箭头随着导航地图的变化始终处于屏幕的预设位置，便 于用户观看指示箭头，从而可以更好地引导用户驾驶车辆，提高了用户的导航体验度。需要说明的是，不同实施例可能产生的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种的组合，也可以是其他任何可能获得的有益效果。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述详细披露仅仅作为示例，而并不构成对本申请的限定。虽然此处并没有明确说明，本领域技术人员可能会对本申请进行各种修改、改进和修正。该类修改、改进和修正在本申请中被建议，所以该类修改、改进、修正仍属于本申请示范实施例的精神和范围。
同时，本申请使用了特定词语来描述本申请的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本申请至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一个替代性实施例”并不一定是指同一实施例。此外，本申请的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，本领域技术人员可以理解，本申请的各方面可以通过若干具有可专利性的种类或情况进行说明和描述，包括任何新的和有用的工序、机器、产品或物质的组合，或对他们的任何新的和有用的改进。相应地，本申请的各个方面可以完全由硬件执行、可以完全由软件(包括固件、常驻软件、微码等)执行、也可以由硬件和软件组合执行。以上硬件或软件均可被称为“数据块”、“模块”、“引擎”、“单元”、“组件”或“系统”。此外，本申请的各方面可能表现为位于一个或多个计算机可读介质中的计算机产品，该产品包括计算机可读程序编码。
计算机存储介质可能包含一个内含有计算机程序编码的传播数据信号，例如在基带上或作为载波的一部分。该传播信号可能有多种表现形式，包括电磁形式、光形式等，或合适的组合形式。计算机存储介质可以是除计算机可读存储介质之外的任何计算机可读介质，该介质可以通过连接至一个指令执行系统、装 置或设备以实现通讯、传播或传输供使用的程序。位于计算机存储介质上的程序编码可以通过任何合适的介质进行传播，包括无线电、电缆、光纤电缆、RF、或类似介质，或任何上述介质的组合。
本申请各部分操作所需的计算机程序编码可以用任意一种或多种程序语言编写，包括面向对象编程语言如Java、Scala、Smalltalk、Eiffel、JADE、Emerald、C++、C#、VB.NET、Python等，常规程序化编程语言如C语言、Visual Basic、Fortran 2003、Perl、COBOL 2002、PHP、ABAP，动态编程语言如Python、Ruby和Groovy，或其他编程语言等。该程序编码可以完全在用户计算机上运行、或作为独立的软件包在用户计算机上运行、或部分在用户计算机上运行部分在远程计算机运行、或完全在远程计算机或服务器上运行。在后种情况下，远程计算机可以通过任何网络形式与用户计算机连接，比如局域网(LAN)或广域网(WAN)，或连接至外部计算机(例如通过因特网)，或在云计算环境中，或作为服务使用如软件即服务(SaaS)。
此外，除非权利要求中明确说明，本申请所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非用于限定本申请流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本申请实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本申请披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本申请实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本申请对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用 于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本申请一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本申请引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档等，特此将其全部内容并入本申请作为参考。与本申请内容不一致或产生冲突的申请历史文件除外，对本申请权利要求最广范围有限制的文件(当前或之后附加于本申请中的)也除外。需要说明的是，如果本申请附属材料中的描述、定义、和/或术语的使用与本申请所述内容有不一致或冲突的地方，以本申请的描述、定义和/或术语的使用为准。
最后，应当理解的是，本申请中所述实施例仅用以说明本申请实施例的原则。其他的变形也可能属于本申请的范围。因此，作为示例而非限制，本申请实施例的替代配置可视为与本申请的教导一致。相应地，本申请的实施例不仅限于本申请明确介绍和描述的实施例。
