道路实景导航系统及方法Road Real-Scene Navigation System and Method

技术领域technical field

本发明涉及一种道路导航系统及方法，特别是关于一种道路实景导航系统及方法。The invention relates to a road navigation system and method, in particular to a road real scene navigation system and method.

背景技术Background technique

传统的道路导航系统未与实地拍摄的360度街景相结合，仅能以电子地图或虚拟场景方式进行导航作业。若现场道路标示被遮蔽，或因道路施工、天色差异等因素，都会造成驾驶人不易以直觉方式确认电子地图或虚拟场景所指示的路线位置。当驾驶人使用传统道路导航系统行驶至匝道路口、高架桥或平面道路交错纵横的路段时，也不易判别传统道路导航系统中电子地图或虚拟场景所标示的路线为何种道路，亦容易因此而发生错上高架桥，或行驶于错误的道路等状况发生，造成驾驶人使用传统道路导航系统进行行车导航上的不便。The traditional road navigation system is not combined with the 360-degree street view shot on the spot, and can only conduct navigation operations in the form of electronic maps or virtual scenes. If the on-site road signs are obscured, or due to factors such as road construction and weather differences, it will be difficult for drivers to intuitively confirm the route position indicated by the electronic map or virtual scene. When the driver uses the traditional road navigation system to drive to the intersection of ramps, viaducts or flat roads, it is not easy to judge the route marked by the electronic map or virtual scene in the traditional road navigation system, and it is easy to make mistakes. Going on viaducts, or driving on wrong roads, etc., will cause inconvenience for drivers to use traditional road navigation systems for driving navigation.

Referring to FIG. 5 , when the driver selects the preset navigation mode, theimage acquisition module 103 plays the 360-degree street view image that is closest to the current date and matches the time point on thedisplay screen 13 . When the driver selects the custom navigation mode, the driver can choose any date to match the 360-degree street view image at the time point to play on thedisplay screen 13 .

参考图6所示，当手持式电子装置1接收到后端主机2传送的360度街景影像画面后，影像获取模块103将360度街景影像画面与道路相关导航信息(例如图6所示的前方100米向左转等导航信息)一并在显示屏幕13上进行播放。当驾驶人选择自订导航模式时，能够根据随着当前位置、使用时间等状况主动调整360度街景影像画面，从而使驾驶人不论何时都可以看到当时与道路状况相仿的360度街景影像画面，让驾驶人能够更直觉地掌握导航信息到达行车终点目的地。Referring to FIG. 6, after the handheldelectronic device 1 receives the 360-degree street view image frame transmitted by the back-end host computer 2, theimage acquisition module 103 combines the 360-degree street view image frame with road-related navigation information (for example, the front view shown in FIG. 6 ). 100 meters turn left and other navigation information) are played on thedisplay screen 13 together. When the driver chooses the custom navigation mode, it can actively adjust the 360-degree street view image according to the current location, usage time and other conditions, so that the driver can see the 360-degree street view image similar to the road conditions at any time screen, so that drivers can more intuitively grasp the navigation information to reach the destination of the driving end.
