AR Virtual Object Positioning via Spatial Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality (AR) technology, electronic devices face challenges in accurately sharing information due to difficulties in obtaining the correct AR information when the receiving device is not positioned within the same field of view as the scene being shared, leading to inaccuracies in displaying virtual objects' locations and numbers.
Innovation Solution
An electronic device equipped with a camera, sensors, and a processor executes an AR application, obtaining images and sensing information to produce and identify virtual objects, and adjusts their display based on user inputs and sensor data, ensuring accurate positioning and sharing of AR information by overlapping images and matching sensing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If AR information is shared based on field of view (FOV) matching, then the accuracy of virtual object location sharing is improved, but the system becomes incapable of obtaining AR information when the receiving device is not positioned within the designated FOV range
Solution Approach 1:
The patent transitions from 2D FOV-based AR information sharing to 3D space-based sharing by introducing depth information and spatial coordinates. The system now operates in three-dimensional space, allowing the receiving device to obtain AR information regardless of its angular position, as long as it is within the spatial range of the virtual object.
Solution Approach 2:
The patent introduces an intermediary coordinate system that acts as a bridge between the transmitting and receiving devices. By converting AR information into spatial coordinates and using these coordinates as intermediaries, the system enables accurate virtual object location sharing without requiring direct FOV alignment between devices.
2Measurement precision
If multiple images are obtained and processed to identify virtual objects, then the accuracy of AR information sharing is improved, but the processing time and system complexity increase
Solution Approach 1:
The patent performs preliminary processing by pre-establishing the coordinate system and pre-identifying virtual objects in the transmitting device. This preliminary action allows the receiving device to quickly obtain and process AR information without requiring extensive real-time processing, thereby reducing processing time while maintaining accuracy.
Solution Approach 2:
The patent creates a copy of the virtual object information in the receiving device by transmitting spatial coordinates and rendering the virtual object locally. This copying approach eliminates the need for the receiving device to perform complex image processing and object identification, significantly reducing processing time while preserving accuracy.
