Single-Camera XR Content Creation Using 2D-to-3D Object Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating 3D content for extended reality (XR) devices is challenging due to the need for complex setups involving multiple cameras or special equipment like stereo cameras and LiDAR sensors, which are costly and difficult to manage, and existing social media platforms primarily support 2D content creation, underutilizing XR technologies for immersive experiences.
Innovation Solution
A single-camera system captures 2D video, which is converted to 3D using a video conversion service that identifies objects through object recognition and audio detection, generates 3D models, and creates interactive 3D content with an index for navigation, allowing dynamic interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras or special equipment (stereo cameras, LiDAR sensors) are used to create 3D content, then the quality and immersion of 3D content is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The patent uses a single camera to capture 2D video, then generates 3D models by copying and manipulating the captured data through computational algorithms. Instead of using multiple physical cameras, the system creates virtual 3D representations from 2D input, significantly reducing hardware complexity while maintaining 3D content quality
Solution Approach 2:
The patent replaces the mechanical system of multiple physical cameras with a computational system that uses object recognition algorithms and 3D model generation software. The mechanical complexity of coordinating multiple cameras is substituted with software-based 3D reconstruction techniques
2Reliability
If multiple cameras or special equipment are used to capture 3D content, then the immersion and interactivity of XR experiences are improved, but the ease of operation and accessibility deteriorate
Solution Approach 1:
The system allows users to create immersive 3D XR content by simply recording 2D video with a standard camera, then automatically generating 3D models through computational copying and transformation of the captured data. This eliminates the need for specialized equipment while maintaining XR immersion quality
Solution Approach 2:
The patent makes the 3D content creation system universal by accepting standard 2D video input from common cameras and transforming it into interactive 3D XR content. This multi-functional approach allows a single device to serve both 2D recording and 3D content creation purposes, greatly improving accessibility
3Device complexity
If 2D video is converted to 3D content through object recognition and 3D model generation, then the cost and complexity of content creation are reduced, but the manufacturing precision and accuracy of 3D models may deteriorate
Solution Approach 1:
The system performs preliminary actions by capturing comprehensive 2D video data from multiple angles and using object recognition algorithms to identify and segment objects before 3D model generation. This preliminary processing ensures that sufficient information is available to create accurate 3D models even from a single camera
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously refines 3D model generation by comparing rendered views with original 2D video frames, adjusting the 3D model parameters to match the captured data. This iterative feedback process maintains manufacturing precision while using simplified hardware

AI summary
Systems and methods are provided herein for creating interactive 3D content for XR devices using a single camera. This may be accomplished by receiving a first piece of content comprising a plurality of segments, wherein the first piece of content is recorded by a first camera. A system may identify a first object within a first segment of the first piece of content and compare the first object with a plurality of 3D models stored in a database. In response to determining that a first 3D model of the plurality of 3D models corresponds to the first object, the system then generates a second piece of content, by combining the first 3D model with the first piece of content. The system also generates an index associated with the second piece of content.
