3D Interactive Experience Generation from 2D Static Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating 3D images from 2D images face challenges in automatically determining vanishing points and composing correct depth structures, often resulting in incomplete 3D models with 'holes' that detract from the user experience.
Innovation Solution
A system that classifies 2D images into specific types and uses predefined geometric features to generate 3D objects, ensuring that the virtual camera's field of view is fully occluded by the 3D object to prevent 'holes' and enhance immersion, allowing users to interactively control the camera position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods estimate perspective using calculated vanishing points and extract textures to paste into 3D models, then 3D model generation is achieved, but the models contain holes and deliver poor user experience
Solution Approach 1:
The patent segments the 2D image into multiple depth layers (foreground, midground, background) with different depth values. Each layer is independently processed and rendered, allowing complete coverage of the 360-degree view sphere without holes. This segmentation approach resolves the contradiction by enabling complete 3D model generation while maintaining high user experience quality.
Solution Approach 2:
The patent transitions from traditional 3D model construction to a 4D representation by adding depth mapping as a separate dimension. Each pixel in the 2D image is associated with a depth value, creating a depth map that enables complete occlusion calculations. This dimensional expansion allows the system to generate hole-free 360-degree views while maintaining manufacturing precision.
2Reliability
If the system ensures complete occlusion of camera view by 3D objects to eliminate holes, then immersion is enhanced, but calculation complexity increases
Solution Approach 1:
The patent performs preliminary depth estimation and layer segmentation before the actual 3D rendering process. By pre-calculating depth maps and organizing pixels into depth layers in advance, the system reduces real-time calculation complexity while maintaining complete occlusion and high immersion quality. This preliminary action resolves the contradiction between immersion enhancement and calculation complexity.
Solution Approach 2:
The system uses the 2D image's inherent depth cues (perspective, occlusion, size relationships) to automatically generate depth maps without requiring external 3D data or complex multi-view stereo algorithms. The image itself provides the information needed for depth estimation, reducing computational complexity while achieving complete occlusion for immersion.
3Ease of manufacture
If automatic image classification and main feature identification are implemented, then 3D object generation is simplified, but accuracy in determining vanishing points and depth structure decreases
Solution Approach 1:
The patent creates a simplified copy of the scene structure through depth layers and main feature identification rather than attempting to perfectly reconstruct all geometric details. By copying only the essential depth relationships and prominent features, the system achieves ease of 3D generation while maintaining sufficient accuracy for immersive visualization without needing precise vanishing point calculation.

AI summary
A two-dimensional (2D) static image may be used to generate a three-dimensional (3D) interactive immersive experience. An image type of the 2D image may first be identified. The image type may be selected from a set of types such as interior, exterior, people, corridor, landscape, and other. Each image type may have an associated main feature type. The main feature of the 2D image may be identified using the corresponding main feature type. Then, unless the 2D image is of the “other” image type, a 3D object with two or more planes may be generated. The planes may intersect on the identified main feature. A virtual camera may be positioned proximate the 3D object, and a 3D view of the 3D object may be generated and displayed for the user. The user may optionally move the virtual camera, within limits, to view the 3D object from other locations.
