AR Landmark Navigation for Finding Parked Items Without GNSS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation applications fail to provide efficient route guidance when a position point lacks a global navigation satellite system (GNSS) signal, leading to time-consuming manual searches for parked items.
Innovation Solution
Utilizing augmented reality (AR) devices to record and utilize key position points during a moving process, enabling intelligent guidance without GNSS signals by outputting movement guidance prompt information based on recorded environmental information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If navigation application uses GNSS signal for route guidance, then navigation accuracy is improved, but system applicability deteriorates in areas without GNSS signals
Solution Approach 1:
The patent introduces key position points as intermediary landmarks between start and end positions. These key position points serve as mediators that break down the navigation path into manageable segments, allowing the system to provide route guidance without relying on continuous GNSS signals. The system captures images at these key position points and uses image recognition to identify and match them, enabling navigation in areas where GNSS is unavailable.
2Adaptability or versatility
If navigation application operates without GNSS signal, then system adaptability is improved, but navigation precision deteriorates due to inability to recognize position point coordinates
Solution Approach 1:
The patent creates visual copies of key position points by capturing images at these locations during the movement process. These image copies are stored and later used for recognition and matching. Instead of relying on precise coordinate data from GNSS, the system uses these visual copies to identify and match position points, thereby maintaining navigation precision without requiring GNSS signals.
Solution Approach 2:
The system performs preliminary actions by capturing and storing images at key position points before the actual navigation and recognition process. This preliminary image capture allows the system to have reference data ready for comparison and matching during navigation, enabling position recognition to occur without real-time GNSS signals.
3Device complexity
If object searches for path manually without route guidance, then device complexity is reduced, but time consumption increases significantly
Solution Approach 1:
The patent segments the navigation path into multiple key position points between the start and end positions. This segmentation transforms a complex, continuous pathfinding problem into a series of simpler, discrete position matching tasks. The system only needs to recognize and match images at these segmented key points rather than continuously tracking the entire path, significantly reducing time consumption while maintaining manageable system complexity.

AI summary
A data processing method and apparatus, and a device and a readable storage medium. The method comprises: in response to a navigation request of a target object for a target article, collecting first environmental change information of the target object during a first movement process by means of an augmented reality device worn by the target object, wherein the first movement process refers to the process of moving from a starting position point to a parking position point of the target article (S101); and when the first environmental change information, which is collected by the augmented reality device, includes a target key position point, outputting movement guidance prompt information associated with the target key position point, wherein the movement guidance prompt information is used for guiding the target object to reach the parking position point, the target key position point refers to a position point which includes target identification degree information and is collected by means of the augmented reality device during the process of moving from the parking position point to a destination position point, and the starting position point refers to any position point where the target object is located during the process of the target object moving from the destination position point to the parking position point (S102). The method can improve the efficiency of searching for the target article.
