AR Navigation Image Provision via Vehicle-to-Server 5G Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems face challenges in providing accurate, real-time images and augmented reality (AR) content, especially at intersections, due to limitations in camera range and delayed traffic information, which affects driving guidance and user experience.
Innovation Solution
An AR image provision method using 5G communication to transmit real-time images from vehicles passing through intersections to an external server, which then generates and displays AR content on the navigation screen, enabling composite guidance by dividing guide points into multiple AR image information points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If camera images are used for navigation guidance, then real-time road visualization is improved, but the viewing distance is limited and long-distance guidance cannot be provided
Solution Approach 1:
The patent merges camera images (providing real-time visualization) with map data (providing long-distance route information) to create a composite navigation display. The map data is overlaid on the camera image background, allowing both real-time road views and extended route guidance to be displayed simultaneously in the navigation interface.
2Loss of information
If traffic information is provided through TPEG, XM, or TMC systems, then traffic condition data is available, but there is a delay at certain intervals and actual road images cannot be viewed
Solution Approach 1:
The patent uses other vehicles as intermediaries to transmit real-time road images and traffic condition information. Instead of relying on delayed broadcast systems like TPEG or TMC, the navigation system receives live camera images from nearby vehicles through vehicle-to-infrastructure communication, providing immediate traffic condition data without the delays inherent in traditional traffic information systems.
3Reliability
If a three-dimensional electronic map is implemented, then the real environment can be better represented, but it requires high manufacturing cost, larger map data space, and more information processing
Solution Approach 1:
The patent replaces complex three-dimensional electronic maps with actual camera images captured from vehicles. Instead of creating and processing detailed 3D map data that requires significant manufacturing cost and data storage, the system uses real photographs of the road environment taken by other vehicles, providing accurate environmental representation with much lower system complexity and data requirements.
4Ease of operation
If AR content is provided for all guide points, then comprehensive navigation guidance is improved, but data usage increases and processing load increases
Solution Approach 1:
The patent applies AR content selectively to specific guide points based on navigation needs rather than providing AR content for all locations. The system identifies key guide points where AR enhancement is most beneficial and loads only those specific AR elements, reducing overall data usage and processing requirements while maintaining comprehensive guidance where it matters most.

AI summary
Disclosed is an AR image provision method of a vehicle navigation system, including transmitting, by a processor, information on a guide point or vehicle speed information to an external server, searching, by an external server, for candidate vehicles based on the information on the guide point or the vehicle speed information, selecting, by the external server, an image providing vehicle from among the candidate vehicles according to priority set by the processor, generating, by the external server, a graphical object to be displayed in a camera image received from the image providing vehicle using augmented reality (AR), and displaying, by the processor, AR image information on the guide point including the camera image and the graphical object on a navigation screen.
