Augmented Reality Anchor Sharing With Segmented Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor sharing methods in augmented reality systems suffer from low accuracy of shared data.
Innovation Solution
The method involves determining target anchors, acquiring both first and second map data corresponding to the anchors, and uploading anchor identifiers, attribute data, and associated map data to a server for sharing between user terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If only first map data corresponding to the target anchor is uploaded, then the data transmission volume is reduced, but the accuracy and integrity of the shared anchor data deteriorates
Solution Approach 1:
The map data is segmented into two distinct parts: first map data that corresponds directly to the target anchor, and second map data that is associated with the first map data. This segmentation allows the system to transmit both types of data separately, ensuring that the anchor sharing accuracy is maintained through comprehensive data transmission while managing the overall data volume in a structured manner.
Solution Approach 2:
The system performs preliminary classification and organization of map data before transmission. By pre-identifying which map data corresponds to the anchor and which is associated with it, the system prepares the data in advance for optimal transmission, ensuring both accuracy and efficient data management without requiring retransmission or additional processing later.
2Measurement precision
If comprehensive map data including both first and second map data is uploaded, then the accuracy and integrity of shared data is improved, but the data transmission volume and processing complexity increases
Solution Approach 1:
By dividing map data into first map data (directly corresponding to the anchor) and second map data (associated with the first map data), the system reduces processing complexity through clear data categorization. This segmentation allows receiving devices to efficiently process and identify the relevant data portions without being overwhelmed by a monolithic data structure, thereby maintaining accuracy while managing complexity.
Solution Approach 2:
The system transmits comprehensive map data (both first and second map data) to ensure complete accuracy, but implements selective processing at the receiving end. The receiving device processes only the portions of data relevant to its needs, applying partial action to avoid unnecessary processing overhead while still achieving complete and accurate anchor reconstruction.
3Speed
If only essential anchor data is transmitted, then the transmission speed is improved, but the integrity and completeness of the shared anchor information deteriorates
Solution Approach 1:
The transmission system segments map data into first map data (essential for anchor identification) and second map data (complementary information). This segmentation enables prioritized transmission where critical data can be sent first to achieve quick anchor establishment, while associated data follows to complete the information set, thereby balancing transmission speed with data integrity.
Solution Approach 2:
The system performs preliminary identification and marking of essential versus associated map data before transmission. This preliminary action allows the receiving device to process and utilize critical anchor information immediately upon receipt, while continuing to integrate complementary data in the background, thus maintaining both fast initial response and complete data integrity.

AI summary
An anchor sharing method includes: a sending end determines at least one target anchor; the sending end acquires target map data according to the target anchor, where the target map data includes: first map data corresponding to the target anchor, and second map data associated with the first map data; the sending end uploads a target anchor identifier of the target anchor, the target map data, and anchor attribute data corresponding to the target map data to a server; a receiving end receives the target anchor identifier sent by the server; if the target anchor corresponding to the target anchor identifier is an anchor in a coordinate system of downloaded map data, the receiving end acquires the anchor attribute data of the target anchor from the server according to the target anchor identifier; and the receiving end displays the target anchor according to the anchor attribute data and the downloaded map data.
