Navigation System Using Terrain Feature Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems struggle to provide intuitive and precise driving routes based on terrain features, especially in complex road sections, leading to potential incorrect route entries by drivers.
Innovation Solution
A navigation method and system that acquires images of the surrounding environment using sensing devices, determines easily recognizable terrain features as target objects, and outputs navigation information to guide drivers along precise routes based on these target objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation systems use conventional route guidance methods, then the system is simple to operate, but the driver may not properly recognize the vehicle turn point in complex road sections and enter an incorrect route
Solution Approach 1:
The system performs preliminary actions by capturing images of the surrounding environment in advance before the vehicle reaches the turn point. The navigation device acquires images at predetermined positions along the driving route, allowing the driver to visually recognize terrain features and turn points before they become critical, thereby improving route recognition accuracy without requiring complex real-time processing during the turn maneuver.
Solution Approach 2:
The system creates visual copies of the physical environment by capturing images of terrain features and surrounding objects. These image copies are displayed to the driver to supplement conventional navigation information, providing a visual representation of the actual road environment that helps the driver recognize turn points and navigate complex road sections more accurately.
2Loss of information
If navigation systems provide detailed turn-by-turn instructions, then the driver receives comprehensive guidance, but the driver may still fail to recognize the actual turn point location in complex road sections
Solution Approach 1:
The system transitions from two-dimensional map-based navigation information to three-dimensional visual representation by capturing and displaying images of the actual surrounding environment. This dimensional change allows the driver to perceive terrain features and turn points in their natural visual context, making it easier to locate and recognize the actual turn point location while maintaining complete navigation information guidance.
Solution Approach 2:
The system introduces images of terrain features and surrounding objects as an intermediary between the driver and the physical environment. These visual intermediaries bridge the gap between abstract navigation instructions and the concrete road environment, helping the driver translate turn-by-turn instructions into accurate physical navigation actions in complex road sections.
3Measurement precision
If the navigation system uses image recognition to identify terrain features, then the navigation becomes more intuitive and precise, but the processing time and computational resources increase
Solution Approach 1:
The system performs image acquisition and preliminary processing in advance before the vehicle reaches critical navigation points. By capturing images at predetermined positions along the driving route ahead of time, the system allows computational processing to occur during non-critical periods, reducing real-time processing delays while maintaining high terrain feature identification accuracy when needed.
Solution Approach 2:
The system extracts only the essential terrain features and turn point information from captured images that are relevant for navigation. Rather than processing and analyzing all image data in full detail, the system identifies and extracts key visual elements such as distinctive terrain features, road markings, and surrounding objects that serve as navigation cues, thereby reducing processing time while maintaining identification accuracy.

AI summary
There is provided a navigation method performed by a computing system. The method may comprise acquiring an image of a surrounding located in front of a vehicle using a sensing device, determining a target object acting as a terrain feature among a plurality of objects included in the acquired image of the surrounding located in front of the vehicle, determining a movement direction in which a driver drives along a driving route at a position of the target object and outputting navigation information including the determined target object and movement direction.
