Navigation device and one-side multi-junction enlarged image display method

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...

In this case, the driver needs to stare at the enlarged picture of the intersection from time to time, for fear of turning ahead or missing the intersection

In the process of driving, if you often stare at the enlarged picture at the intersection, it will inevitably distract the driver's attention. In other words, when encountering such a situation, the driver needs to be distracted to judge how to go. These reactions are undoubtedly The safety level of the driver has been reduced during driving
