Solution Overview
Problem
Augmented reality devices face challenges in efficiently obtaining and processing information about real-world spaces to display virtual images effectively, requiring significant computation and depth information calculation.
Innovation Solution
An electronic device equipped with a camera, processor, and memory that obtains a 2D image, identifies objects, and retrieves spatial information from an external server to display virtual objects, allowing for realistic obstruction effects without 360-degree photography or depth sensors, thus reducing computational load.

Engineering Contradiction Analysis
1Measurement precision
If depth information calculation is performed to display virtual images realistically, then the realism and accuracy of virtual object display is improved, but the computational load and processing time increase significantly
Solution Approach 1:
The patent uses a pre-stored three-dimensional model as a copy of the real-world object instead of calculating depth information from scratch. The processor retrieves the stored 3D model based on object type identification and uses it to generate the virtual image, avoiding complex real-time depth calculations while maintaining visual accuracy
Solution Approach 2:
The three-dimensional models are prepared and stored in advance in the memory before being needed. This preliminary action allows the processor to simply retrieve and use the pre-computed spatial information during AR operations, eliminating the need for complex real-time computation
2Measurement precision
If 360-degree photography or depth sensors are used to obtain spatial information, then the accuracy of virtual object placement is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of using complex sensors or 360-degree cameras to capture spatial information, the system uses a simple camera to capture a 2D image and then retrieves a pre-stored three-dimensional model that copies the spatial characteristics of the object. This approach achieves accurate virtual object placement without adding complex hardware
Solution Approach 2:
The patent introduces a database of pre-stored three-dimensional models as an intermediary between the simple camera input and the virtual reality output. This intermediary provides the complex spatial information that would otherwise require complex sensors, allowing the system to use only basic imaging hardware
3Measurement precision
If extensive depth calculations are performed to achieve realistic obstruction effects, then the visual realism is improved, but the processing speed decreases
Solution Approach 1:
The pre-stored three-dimensional model already contains the spatial and geometric information needed to determine obstruction relationships. The processor simply uses this stored data to render the virtual image with realistic obstruction effects, avoiding the need for complex real-time depth calculations that would slow down processing
