3D Map Anchor Pose Adjustment for Stable AR Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display of anchor points in augmented reality (AR) systems becomes staggered when the three-dimensional reality scene changes, leading to dislocation issues.
Innovation Solution
An information processing method that determines and adjusts the pose of anchor points based on change information, associating them with a first image frame of the three-dimensional map to maintain stability during scene changes.

Engineering Contradiction Analysis
1Reliability
If the three-dimensional map is updated or changed to reflect new scene information, then the map accuracy and currency are improved, but the anchor point display becomes staggered and dislocated
Solution Approach 1:
The system pre-associates anchor points with specific image frames before map updates occur. When a map change is detected, the system retrieves the pose information from the pre-associated image frame and applies it to the anchor point, ensuring the anchor point smoothly transitions with the map update without stagger or dislocation. This preliminary association enables the anchor point to maintain its spatial relationship with the updated map content.
2Stability of the object's composition
If the anchor point is fixed to the original image frame, then the anchor point position remains stable, but it becomes dislocated when the three-dimensional map changes
Solution Approach 1:
The system dynamically adjusts the anchor point's pose by associating it with image frames that correspond to the current map state. When the map changes, the system detects the change, retrieves the appropriate image frame pose, and updates the anchor point accordingly. This dynamic adjustment mechanism allows the anchor point to maintain both stability (by referencing fixed image frame data) and accuracy (by updating with current map state information).

AI summary
Embodiments of the present disclosure provide an information processing method and device, the method includes: in response to detecting first change information that a three dimensional map is changed, determining second change information of an anchor point based on the first change information, the anchor point being pre-associated with a first image frame of the three dimensional map; adjusting a pose of the anchor point based on the second change information. According to the method in the present disclosure, when the three dimensional map is changed, the anchor point of the three dimensional map can change with the change of the first image frame with which the anchor point is associated, so that the display of the anchor point remains relatively stable, and the problem that the display of the anchor point is stagger when the three dimensional map is changed is avoided.
