Navigation Video Guidance for Complex Route Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems rely on abstract maps, which can be difficult for users to interpret, especially in complex environments, leading to missed turns and reduced navigation accuracy.
Innovation Solution
A method and device for generating and using navigation videos that match specific starting and ending points, incorporating parameters like road names, seasons, weather, and driving speed, allowing for accurate video selection and playback to guide users through routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If abstract maps are used for navigation, then the navigation system structure is simple, but the user identification difficulty increases and navigation accuracy decreases in complex environments
Solution Approach 1:
The patent creates video copies of actual road scenes that users can watch during navigation. These video copies replicate the visual appearance of the road environment, allowing users to directly recognize their current location and upcoming turns without having to interpret abstract map symbols. The video is played back at a speed synchronized with the user's actual driving speed, providing an intuitive visual reference that simplifies navigation in complex environments.

Solution Approach 1:

The video is played back at a speed synchronized with the user's actual driving speed, providing an intuitive visual reference that simplifies navigation in complex environments.
Solution Approach 2:
The system provides continuous visual feedback by playing the pre-recorded video at a speed that matches the user's actual driving speed. This creates a synchronized feedback loop where the video progression corresponds to the user's physical movement along the route, helping users confirm they are on the correct path and reducing the likelihood of missed turns.
3Manufacturing precision
If navigation videos are generated and matched based on multiple parameters, then the navigation accuracy improves, but the system complexity and processing time increase
Solution Approach 1:
The patent performs video generation, parameter extraction, and video matching operations in advance, before the user actually needs navigation. Video clips are pre-recorded from vehicles traveling along various routes, and their parameters (starting point, ending point, route, season, weather, driving speed) are extracted and stored in a database. When a user needs navigation, the system simply queries the database for matching videos based on the user's requested parameters, dramatically reducing real-time processing requirements.
