Navigation Device Route Overlay on Front Camera Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices fail to provide an optimum route for vehicle drivers as they do not consider the presence of peripheral vehicles, leading to a mismatch between the displayed route and the actual traveling situation.
Innovation Solution
A navigation device that overlays a travel route on a front-view camera image, determining the position of the ego vehicle and peripheral vehicles using multiple sensors and cameras, and adjusts the route to dodge or follow the peripheral vehicle, displaying the adjusted route on a display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional navigation devices display routes irrespective of peripheral vehicles, then the navigation system is simple and easy to operate, but the route provided does not match the actual traveling situation causing driver confusion
Solution Approach 1:
The patent combines multiple detection systems (cameras, sensors) with the navigation route determination system to create an integrated system that considers both route information and peripheral vehicle positions, resolving the contradiction by merging previously separate functions into a unified navigation system
Solution Approach 2:
The patent introduces an intermediary processing system that receives data from multiple sensors and cameras, processes this information to determine peripheral vehicle positions, and then integrates this data with route information to provide accurate navigation that reflects actual traveling conditions
2Ease of operation
If the navigation device overlays route on camera images, then the visual display is enhanced, but the system requires multiple sensors and processing components increasing complexity
Solution Approach 1:
The patent makes the camera system serve multiple functions: it captures images for visual route overlay display and simultaneously detects peripheral vehicles for route determination, eliminating the need for separate detection devices and reducing overall system complexity while maintaining enhanced visual guidance
3Measurement precision
If the system determines route based on multiple sensor inputs, then the route accuracy improves, but the processing time and computational load increase
Solution Approach 1:
The patent performs preliminary actions by continuously monitoring and pre-processing sensor data in real-time, so when route determination is needed, the system already has processed position information from cameras and sensors readily available, reducing the time required for accurate route calculation

AI summary
Disclosed are provided a navigation device or a method for overlaying a travel route, in which the position of other vehicles located on the travel route is considered, on an image obtained from a front-view camera, wherein a navigation device includes: a display device configured to display an image acquired from a front-view camera of a vehicle, to overlay a travel route on the displayed image, and to display the overlaid resultant image; and a processor configured to determine a travel route starting from a position of the vehicle acting as an ego vehicle, when a peripheral vehicle is located at the determined travel route, to determine a travel route along which the ego vehicle dodges or follows the peripheral vehicle on the basis of the position of the peripheral vehicle, and to display the determined travel route on the display unit.
