Real-time square surface looking board guidance design method of navigation apparatus

Abstract

The invention relates to a real-time square surface looking board guidance design method of a navigation apparatus. According to the present invention, the method is achieved through a geographic information reading module, a GPS receiving / positioning module, a path planning module, an intersection guidance data making module, a guidance control module, and a display module; based on different use requirements of users in the two cases of the path with no planning and the path with planning, two sets of real-time image guidance control implementation schemes are designed, wherein the first scheme is real-time image guidance control in the case of the path with no planning, and the second scheme is real-time image guidance control in the case of the path with planning; and the design method has the following advantages that: on the basis of the existing navigation guidance services, innovative functions are provided, real-time, dynamic, intelligent and humanized features are added, defects that the traditional square surface looking board has a fixed position, is immovable, and can not initiatively provide turning prompts for drivers are effectively overcome, and distraction with looking the square surface looking board indication board erected on the roadside is not required during a driving process so as to reduce driving risk and protect safety of personnel and vehicles.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a method for designing a real-time kanban guide of a navigation device. Background technique [0002] With the rapid development of the automotive electronics industry, car navigation systems have become more and more familiar and accepted by car buyers. Car navigation system is a complex that provides drivers with services such as electronic maps, vehicle positioning, real-time voice guidance, and real-time screen guidance based on embedded hardware, global GPS positioning, and geographic information data. [0003] At present, the navigation on the market has provided a variety of real-time image guidance services. When the driver approaches the intersection, the detailed map and steering information of the intersection ahead will be displayed on the screen of the embedded hardware. Generally speaking, the displayed content includes the following items: a detailed map with t...

Problems solved by technology

First of all, the position of the signboard in the real world cannot be moved. Drivers often have to drive close to the car to look up to see the sign clearly, and even miss it if they don’t see the signboard due to the speed of the car.

Moreover, in the process of driving, distracting to check the signs on the side board will undoubtedly affect driving safety.

[0007] Secondly, the side sign boards in the real world cannot directly provide steering information and driving routes to the driver. It takes a certain amount of time for the driver to complete the understanding-analysis-traveling route judgment of the side sign boards.

In the end, the judgment result of the driver is not always correct, and the situation of going the wrong way in the actual scene also happens from time to time
