AR Navigation Sidewall Overlay for Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of positioning technology, such as GPS, used in augmented reality guidance is relatively low, leading to misaligned or inaccurate navigational information, potentially confusing users and causing them to be directed to cross streets unnecessarily.
Innovation Solution
A method that determines the position and orientation of a mobile terminal, uses map data to augment the display of visible images by presenting navigational information on sidewall surfaces within the image, ensuring accurate and intuitive direction signs, even when the terminal's orientation or position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning technology is used to determine user location in augmented reality guidance, then the system can provide directional information and navigation guidance, but the positioning accuracy is relatively low causing misalignment between navigational information and visual representation
Solution Approach 1:
The patent introduces an intermediary system that includes a camera to capture real-time images of the user's surroundings, image processing algorithms to identify physical landmarks and features, and a mapping system to correlate these visual features with GPS coordinates. This intermediary layer compensates for GPS inaccuracies by using visual recognition to determine the user's precise location and orientation relative to physical structures, thereby aligning navigational information with the actual visual representation.
Solution Approach 2:
The patent merges multiple data sources including GPS positioning data, camera-captured images, image recognition results, and map data into a unified augmented reality display. By combining these diverse data streams, the system achieves higher overall accuracy than GPS alone, as the visual recognition component corrects positioning errors and the integrated display presents navigational information that is accurately overlaid on the real-world view.
2Ease of operation
If directional arrows are displayed in augmented reality to indicate travel direction, then users receive navigation guidance, but low positioning accuracy causes the arrows to be displaced from the actual user location and misaligned with streets and sidewalks
Solution Approach 1:
The system uses image recognition as an intermediary to identify physical landmarks, street layouts, and sidewalk features in the captured images. This visual information serves as a reference framework that corrects the displacement and misalignment caused by inaccurate GPS data, allowing directional arrows to be properly positioned and oriented relative to actual streets and sidewalks rather than being offset from the user's true location.
3Productivity
If GPS positioning is used to determine user location, then navigation information can be provided, but users may be directed to cross streets unnecessarily due to difficulty in pinning down the precise location
Solution Approach 1:
The system implements feedback by continuously comparing the user's GPS-reported location with the actual visual features detected by the camera and image recognition system. This real-time feedback loop allows the system to detect and correct positioning errors, preventing the user from being misled into unnecessary street crossings. The navigational directions are dynamically adjusted based on the corrected position, ensuring efficient routing that avoids wasteful maneuvers.
