Abstract

The invention relates to a navigation device comprising an external storage controller, a GPS positioning module, user input equipment, a CPU, an ROM, an RAM, a map information reading module, an external memory, a guide line computing module, a junction identifying and judging module, a timing control module of a junction enlarged image, a user interface display module, a display module of the junction enlarged image, an electronic map display module, an image synthesis module, a display controller and a display device which are respectively connected with a bus by a data line; a one-side multi-junction enlarged image display method is realized in such a process: the junction identifying and judging module is used for judging a relative distance between a vehicle and a next junction; and the display module of the junction enlarged image is used for numbering one-side junctions and drawing numbers of the one-side junctions on the basis of a general junction enlarged image. The invention has the advantage of displaying the numbers of the junctions on a screen for the steering junctions of vehicles in an emphasis mode.

Description

technical field [0001] The invention relates to the field of car navigation systems, and particularly provides a navigation device and a method for displaying enlarged images of multi-junctions on the same side. Background technique [0002] With the rise of the automotive electronics industry, car navigation systems have begun to come into people's attention. Car navigation system is a complex that provides drivers with electronic maps, vehicle positioning, real-time voice guidance, real-time picture guidance and other services based on embedded hardware, global GPS positioning, and geographic information data. [0003] The enlarged map of the intersection is one of the main manifestations of the real-time picture guidance service. When the driver approaches the intersection, a detailed map and steering information of the intersection ahead will be displayed on the screen of the embedded hardware. Generally speaking, its display content includes the following items: [0...
