Real scene navigation method and navigation terminal

Abstract

The invention is applicable to the technical field of positioning navigation and provides a live-action navigation method. The live-action navigation method comprises the following steps of: acquiring the current position of a vehicle in real time; acquiring a live-action image of environment in which the vehicle is located in real time; matching the live-action image with a pre-stored electronic map, and establishing a mapping relation; marking navigation prompt information according to the mapping relation between the live-action image and the electronic map, a pre-planned path and the current position; analyzing real-time road condition information according to the live-action image; and optimizing a navigation path according to the real-time road condition information. Correspondingly, the invention also provides a navigation terminal. Therefore, by the invention, a navigation image is intuitive and accurate by using a live-action navigation technology, and the navigation path can be optimized according to a real-time road condition, so navigation indication is intelligent and efficient, and a navigation experience of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of positioning and navigation, in particular to a real-scene navigation method and a navigation terminal. Background technique [0002] GNSS (Global Navigation Satellite System, Global Navigation Satellite System) uses radio signals emitted by navigation satellites to find the position of navigation objects such as vehicles relative to the satellite, and then calculates and determines the position of the navigation object on the earth based on the known position of the satellite relative to the ground. Technology. GNSS mainly includes GPS (the global satellite positioning system established by the United States), GLONASS (the satellite navigation system established by Russia), Compass (the Beidou satellite navigation system established by China), and Galileo (the satellite navigation system established by the European Union). Most of the current navigation solutions use GNSS satellite navigation data and st...

Problems solved by technology

[0003] Chinese patent application CN200910170836.5 discloses a street view dynamic navigation system and its method. The scheme needs to establish a street view image database in the whole area, and the street view image is called out from the database during use, but the street view image is not consistent with the actual scene seen by the user. There are still differences, resulting in a poor user experience

[0004] Chinese patent application CN201010269448.5 discloses a real-time road navigation method, which uses real-time captured images and displays navigation prompt information in the images; however, the map data is not associated with real-time road conditions, and the given path is not necessarily The best choice, the user experience is not good enough

[0005] In summary, the existing vehicle navigation technology obviously has inconvenience and defects in actual use, so it is necessary to improve it.
