Solution Overview

Problem

The process of converting 2D motion pictures to 3D is labor-intensive and time-consuming, particularly due to the need for manual object separation and filling occlusion regions, which can result in visible artifacts and is not scalable for meeting tight cinematic release schedules.

Innovation Solution

A systematic process architectural model for converting 2D image sequences to 3D, involving the collection of image data cues and other processing information, using a multi-mode computing structure for object processing and occlusion region filling, and an automated system for rendering and updating render data records to ensure efficient and adaptable 3D image production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual object separation and occlusion region filling are used to convert 2D to 3D, then visual quality can be maintained, but the process becomes labor-intensive and time-consuming

Engineering Contradiction:
Improvevisual qualityVSAvoidconversion time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent segments the 2D image into multiple layers including foreground objects, background, and occlusion regions. This segmentation allows automated processing of each layer with specific algorithms, maintaining visual quality while reducing manual intervention. The layered structure enables parallel processing and automated occlusion filling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary depth map generation and object separation before final 3D rendering. By pre-processing the 2D image to identify objects, estimate depths, and separate layers in advance, the system reduces the time required for the actual conversion process while maintaining quality through automated algorithms.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual processing methods are used for 2D to 3D conversion, then quality can be maintained, but scalability for tight release schedules is limited

Engineering Contradiction:
Improveconversion qualityVSAvoidconversion scalability
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical processing with automated computational algorithms. Computer vision algorithms automatically perform object detection, depth estimation, and layer separation, while machine learning models handle occlusion region filling. This substitution enables scalable processing that can meet tight release schedules without sacrificing quality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the processing parameters from manual operation to automated algorithmic operation. By adjusting parameters such as depth map resolution, layer separation thresholds, and occlusion filling confidence levels, the system maintains quality while achieving high productivity through automated batch processing.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated algorithms are used for object processing, then productivity increases, but handling frequent changes and updates becomes more complex

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a dynamic processing pipeline where algorithms can be selectively applied to different image regions and objects. The system dynamically adjusts processing parameters and algorithm selection based on image content analysis, enabling efficient handling of frequent changes without requiring complete re-processing of entire scenes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary analysis to identify objects, regions, and features that require processing before applying automated algorithms. This pre-processing step creates a structured representation that simplifies subsequent automated processing and makes the system more adaptable to changes, as only affected regions need re-processing.

Inventive Principle:
Principle #10Preliminary action

4Manufacturing precision

If comprehensive processing information is collected for accurate 3D conversion, then visual quality improves, but the amount of data and processing complexity increases

Engineering Contradiction:
Improve3D conversion accuracyVSAvoiddata volume
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies different processing depths and information collection levels to different regions of the image based on their importance. High-priority regions such as foreground objects receive comprehensive processing with detailed depth maps and multiple views, while background regions use simplified algorithms. This local quality approach maintains overall visual quality while reducing total data volume.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent collects processing information selectively rather than comprehensively for all image elements. It focuses on gathering essential depth and motion data for objects that significantly impact 3D perception, using partial information for less critical regions. This approach achieves acceptable conversion accuracy with reduced data requirements.

Inventive Principle:
Principle #16Partial or excessive action
