Generation method and device of guidance and prompt marks

Abstract

The invention discloses a generation method of guidance and prompt marks. The method comprises the following steps: receiving guidance and prompt commands of an intersection, and determining information of entering roads and exiting roads of the intersection; dividing angle regions corresponding to preset guidance directions; determining the relationship between the exiting road information and the angle regions to obtain preset guidance directions corresponding to the exiting roads; compounding the guidance and prompt marks comprising the entering roads and the exiting roads. With adoption ofthe method, the actual roads are converted into the preset guidance directions, directions of the entering roads and the exiting roads are displayed, directions of other exiting rods at the intersection can also be displayed, the road distribution situation of the intersection is displayed clearly and visually without consuming too much storage space, and accordingly, discrimination of users to the roads is improved, and the condition of taking the wrong road due to complexity of the intersection is effectively reduced.

Description

technical field [0001] The invention relates to a method and device for generating a guidance prompt mark. Background technique [0002] With the continuous development of automotive electronics technology, car navigation, as an important component of automotive electronic products, is increasingly favored by the majority of users. At the same time, the competition for car navigation is becoming increasingly fierce, and car navigation is bound to need to continue to grow and enrich its functions. In order to better serve the majority of users, developing richer and more practical car navigation functions to provide users with more intuitive and accurate guidance is undoubtedly an effective means to increase product competitiveness. [0003] In the prior art, when vehicle navigation provides direction guidance at intersections, it usually adopts a simple and intuitive simple guidance method, that is, the route to be guided is displayed in the form of pictures, so that users c...

Problems solved by technology

[0003]In the prior art, when the car navigation provides direction guidance at intersections, it usually adopts a simple and intuitive simple guidance method, that is, the route to be guided is displayed in the form of pictures , so that users can quickly locate the driving direction without paying attention to other guidance details such as voice broadcasts; the simple guidance can only display the traveling direction of the current driving route, there is no background route comparison, and the displayed direction is only the preset direction Eight simple directions, and as the road conditions become more and more complex, there are more and more roads with similar angles. Such simple directions can only provide approximate directions. It is difficult for users to find the direction of the actual route, and it is easy to go in the wrong direction.
