Stereo-Aware Image Editing via 3D Model Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for stereoscopic three-dimensional image production and manipulation lacks effective tools for consistently editing multiple images to create finished stereoscopic products, particularly in handling and enhancing stereo image pairs.
Innovation Solution
The development of methods and systems for stereo-aware image editing, which involve building a three-dimensional model of a stereo scene from input images, computing camera parameters, modifying the model, and re-rendering the scene to produce edited stereo pairs that are consistent with the three-dimensional model, allowing for operations like painting, cutting, and pasting while maintaining three-dimensional consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional image editing tools are used on stereo image pairs, then editing operations can be performed on individual images, but three-dimensional consistency between left and right images is lost
Solution Approach 1:
The patent transitions from editing two-dimensional images to editing a three-dimensional scene model. By representing the stereo scene as a 3D model with vertices and performing edits in this third dimension, the system maintains depth ordering and geometric consistency while enabling flexible editing operations. The edited 3D model is then re-rendered to produce consistent stereo image pairs.
2Adaptability or versatility
If stereo image pairs are edited independently, then editing flexibility is improved, but depth ordering and geometric consistency deteriorate
Solution Approach 1:
The patent introduces a three-dimensional scene model as an intermediary between the original stereo images and the edited output. This intermediate representation serves as a mediator that preserves geometric relationships and depth information while allowing flexible editing operations. The model acts as a bridge that maintains consistency throughout the editing process.
3Measurement precision
If three-dimensional modeling is performed from stereo images, then depth information is captured, but processing complexity increases
Solution Approach 1:
The patent creates a three-dimensional copy or representation of the stereo scene rather than directly manipulating the original images. This 3D model copy preserves all depth and geometric information while providing a more manageable structure for editing. The copying process captures essential scene geometry that can then be manipulated with simpler operations than direct stereo image processing.

AI summary
Embodiments of methods and systems for stereo-aware image editing are described. A three-dimensional model of a stereo scene is built from one or more input images. Camera parameters for the input images are computed. The three-dimensional model is modified. In some embodiments, the modifying the three-dimensional model includes modifying one or more of the images and applying results of the modifying one or more of the images to corresponding model vertices. The scene is re-rendered from the camera parameters to produce an edited stereo pair that is consistent with the three-dimensional model.
