图2为符合本发明实施例的一种基于智能终端的导航系统的结构示意图。
具体实施方式
以下结合附图与具体实施例进一步阐述本发明的优点。
本发明提供了一种基于智能终端的导航方法及导航系统。采用本发明提供的一种基于智能终端的导航方法及导航系统后，用户无需额外安装地图应用程序，节省智能终端的内存。用户需要导航时，仅需打开智能终端的相机功能，智能终端内置的导航系统通过相机预览到的实时图像即可获取用户当前所在的实时位置，结合用户输入的目标位置，可以为用户提供由实时位置到目标位置的实景导航路线。当导航系统通过预览到的实时图像获取到用户所在的实时位置发生变化时，导航系统规划的导航路线也会作相应地变化，无需用户额外地手动操作，方便快捷，为用户提供一种更好的使用体验。
如图1所示，为符合本发明实施例的一种基于智能终端的导航方法的流程示意图。本发明实施例提供了一种基于智能终端，如手机、平板电脑等智能设备的导航方法，具体地，包括如下步骤：
通过所述智能终端的相机预览一实时图像；
具体地，启动智能终端如手机、平板电脑等设备，找到智能终端界面上的导航应用程序的图标，点击导航应用程序图标，打开导航应用程序。进入导航应用程序后，选择开启智能终端的摄像头。摄像头开启，预览一当前用户所在位置的实时图像，完成实时图像的预览。
获取所述实时图像中包含的实时位置数据；
具体地，通过智能终端内置相机获取到预览的实时图像后，智能终端通过内置的全 球定位系统GPS会自动获取实时图像中所包含的实时位置数据。全球卫星定位系统(Global Positioning System，简称GPS)是一种结合卫星及通讯发展的技术，利用导航卫星可以对标的物进行定位、测时和测距。因此，智能终端通过GPS获取到实时图像中所包含的实时位置数据表明智能终端已获取智能终端当前所在的具体位置。
所述智能终端接收一目标位置；
具体地，用户在导航系统中输入一目标位置。该目标位置，也就是用户需要通过导航的帮助抵达的目的地。该目的地可以是市内的，也可以是市外，甚至国外的。但基于GPS导航的精度，目的地的设置需要是距离用户所在的初始位置即起点位置的100米范围以外的地方。例如，当用户所在的当前位置距离上海中心大厦超过100米范围时，该用户可以在导航系统中输入“上海中心大厦”作为其目标位置。
根据所述目标位置，生成所述目标位置数据；
具体地，待智能终端获取到用户输入的目标位置后，智能终端内置的GPS定位系统根据用户输入的目标位置进行转化，将获取到的目标位置转化为一描述目标位置的目标位置数据。例如，当用户在智能终端的导航系统中输入“上海中心大厦”时，GPS定位系统将“上海中心大厦”字样的目标位置转化为能描述“上海中心大厦”具体所在位置的目标位置数据。
根据所述实时位置数据与所述目标位置数据，生成一从所述实时位置到所述目标位置的导航路线；
当GPS根据预览的实时图像获取到用户当前所在的实时位置数据，并根据用户输入的目标位置生成一与目标位置相应的目标位置数据后，GPS进一步地会根据实时位置数据与目标位置数据，生成一从实时位置到目标位置的导航路线，即完成从用户所在的实时位置到目标位置的路线规划。例如，当GPS根据人民广场的实时图像获取到实时图像中所包含的实时位置数据描述的实时位置为“人民广场”，随后获取到用户输入的目标位置为“上海中心大厦”并根据该目标位置生成一描述“上海中心大厦”的目标位置数据后，会自动对从人民广场到上海中心大厦的路线作规划，以帮助用户明确从人民广场到上海中心大厦的路线。
优选地，所述导航路线根据所述实时位置的变化作相应调整。
优选地，随着用户根据智能终端导航应用程序不断向目标位置靠近，智能终端所采集到的实时图像也会随之发生变化，进而GPS获取到的实时位置数据也会随之改变。因此，GPS会不断更新其先前规划的路线，随着实时位置的变化实时更新改变导航路线，为用户提供一种可为精确的导航路线。
优选地，所述导航路线包含驾车路线、步行路线、公共交通路线、骑行路线中的一种或多种。
优选地，GPS根据预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出的由实时位置到目标位置的导航路线包括多种形式的路线，例如：驾车路线、步行路线、公共交通路线、骑行路线等。以此，本发明实施例中的一种基于智能终端的导航方法能够为用户提供全面的导航路线，可以满足各种用户不同的使用需求。
在所述实时图像中输出所述导航路线。
具体地，当智能终端中的GPS根据预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出的由实时位置到目标位置的导航路线后，智能终端会在包含实时图像的预览界面中输出GPS规划出的导航路线。通过本发明实施例中的一种基于智能终端的导航方法，用户可以在相机的图像预览界面中看到GPS规划的导航路线。
优选地，当从所述实时位置到所述目标位置存在多条所述导航路线时，所述智能终 端优先输出一用时最短的所述导航路线。
优选地，当智能终端中的GPS根据预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出多条由实时位置到目标位置的导航路线后，智能终端会自动根据导航路线需要的时间排序，优先向用户提供一条所需路程时间最短的导航路线。
优选地，在所述实时图像中输出所述导航路线的步骤中，进一步包括叠加所述导航路线与所述实时图像，以生成一完整的三维实景导航画面。
优选地，智能终端的相机在采集所得的实时图像中输出导航路线时，可以进一步地将生成的导航路线与采集所得的实时图像叠加，从而可以在实时图像中显示导航路线信息，以生成一完整的三维实景导航画面。例如在实时图像中显示转弯方向箭头，直行箭头，以及距离目的地的实际距离等导航信息。
如图2所示，为符合本发明实施例的一种基于智能终端的导航系统的结构示意图。本发明实施例中进一步提供了一种基于智能终端，如手机、平板电脑等智能设备的导航系统，该导航系统可以于Android操作环境下运行。具体地，本发明提供的一种基于智能终端的导航系统包含预览模块、定位模块、接收模块及输出模块；

具体地，本发明实施例中的一种基于智能终端导航系统包含一接收模块。接收模块接收用户输入的目标位置。该目标位置，也就是用户需要通过导航的帮助抵达的目的地。该目的地可以是市内的，也可以是市外，甚至国外的。但基于GPS导航的精度，目的地的设置需要是距离用户所在的初始位置即起点位置的100米范围以外的地方。当接收模块接收到一目标位置后，通过通讯连接，将目标位置发送至定位模块。例如，当接收模块接收到用户录入的“上海中心大厦”作目标位置后，会将“上海中心大厦”这一目标位置发送至定位模块。
所述定位模块，与所述预览模块、所述输入模块及所述输出模块通讯连接，提取所述实时图像中包含的实时位置数据；根据所述目标位置生成目标位置数据；根据所述实时位置数据与所述目标位置数据，生成一从所述实时位置到所述目标位置的导航路线；并发送所述导航路线至所述输出模块；
具体地，本发明实施例中的一种基于智能终端导航系统包含一定位模块，该定位模块与预览模块、接收模块、输出模块通讯连接。定位模块接收到预览模块发出的实时图像后会自动获取实时图像中所包含的实时位置数据；此外，当定位模块接收到接收模块发出的目标位置时，会根据该目标位置生成一描述该目标位置的目标位置数据。生成该目标位置数据后，定位模块会根据实时图像中包含的实时位置数据与生成的目标位置数据，对实时位置到目标位置的路线进行规划。规划完成后，将实时位置到目标位置的路线发送至输出模块中。例如，当定位模块根据人民广场的实时图像获取到实时图像中所包含的实时位置数据描述的实时位置为“人民广场”，随后获取到由接收模块接收所得的目标位置为“上海中心大厦”并根据该目标位置生成一描述“上海中心大厦”的目标位置数据后，定位模块会自动对从人民广场到上海中心大厦的路线作规划，以帮助用户明 确从人民广场到上海中心大厦的路线。
优选地，所述定位模块生成的所述导航路线根据所述实时位置的变化作相应调整。
优选地，随着用户根据智能终端导航系统不断向目标位置靠近，预览模块所采集到的实时图像也会随之发生变化，进而定位模块获取到的实时位置数据也会随之改变。因此，定位模块会不断更新其先前规划的路线，随着实时位置的变化实时更新改变导航路线，为用户提供一种可为精确的导航路线。
优选地，所述导航路线包含驾车路线、步行路线、公共交通路线、骑行路线中的一种或多种。
优选地，定位模块根据预览模块预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出的由实时位置到目标位置的导航路线包括多种形式的路线，例如：驾车路线、步行路线、公共交通路线、骑行路线等。以此，本发明实施例中的一种基于智能终端的导航系统能够为用户提供全面的导航路线，可以满足各种用户不同的使用需求。
所述输出模块，与所述定位模块、所述预览模块通讯连接，用于在所述实时图像中输出所述导航路线。
具体地，当智能终端导航系统中的定位模块根据预览模块预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出的由实时位置到目标位置的导航路线后，定位模块将规划所得的导航路线发送到输出模块中。智能终端导航系统的输出模块会通过通讯连接，在包含实时图像的预览界面中输出定位模块规划出的导航路线。通过本发明实施例中的一种基于智能终端的导航系统，用户可以在实时图像的预览界面中看到定位模块规划的导航路线。
优选地，当从所述实时位置到所述目标位置存在多条所述导航路线时，所述输出模块优先输出一用时最短的所述导航路线。
优选地，当智能终端中的定位模块根据预览所得的实时图像获取到的实时位置数据与由目标位置生成的目标位置数据所规划出多条由实时位置到目标位置的导航路线后，输出模块会自动根据导航路线需要的时间排序，优先向用户提供一条所需路程时间最短的导航路线。
优选地，所述输出模块进一步包括叠加所述导航路线与所述实时图像，以生成一完整的三维实景导航画面。
优选地，智能终端的输出模块在接收到预览模块采集所得的实时图像，以及定位模块生成的导航路线后，可以进一步地将生成的导航路线与采集所得的实时图像叠加，即实现在实时图像中显示导航路线信息，以生成一完整的三维实景导航画面。例如在实时图像中显示转弯方向箭头，直行箭头，以及距离目的地的实际距离等导航信息。
采用本发明提供的一种基于智能终端的导航方法及导航系统后，用户无需额外安装地图应用程序，节省智能终端的内存。用户需要导航时，仅需打开智能终端的相机功能，智能终端内置的导航系统通过相机预览到的实时图像即可获取用户当前所在的实时位置，结合用户输入的目标位置，可以为用户提供由实时位置到目标位置的实景导航路线。当导航系统通过预览到的实时图像获取到用户所在的实时位置发生变化时，导航系统规划的导航路线也会作相应地变化，无需用户额外地手动操作，方便快捷，为用户提供一种更好的使用体验。
应当注意的是，本发明的实施例有较佳的实施性，且并非对本发明作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本发明技术方案的范围内。
