Solution Overview

Problem

Existing VR image scaling methods using mainstream encoding schemes like H.264, H.265, or HEVC result in equal-proportion scaling of the whole VR image, failing to provide a stereoscopic and realistic VR experience.

Innovation Solution

An image processing method that utilizes six-degree-of-freedom data to determine a motion vector and scale specific objects within the VR image, employing a 6-parameter affine model to achieve stereoscopic scaling effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If equal-proportion scaling of the whole VR image is used, then the implementation is simple using mainstream encoding schemes, but the stereoscopic and realistic VR experience is lost

Engineering Contradiction:

Improveimplementation simplicityVSAvoidstereoscopic scaling accuracy

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent segments the VR image into multiple regions based on depth information, identifying different objects or areas that require different scaling treatments. This allows selective scaling of specific regions rather than uniform scaling of the entire image, thereby achieving stereoscopic effects while maintaining implementation feasibility through region-based processing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different scaling qualities to different regions of the VR image based on their depth characteristics. Objects or regions closer to the user receive different scaling treatment compared to distant objects, creating local quality variations that produce the desired stereoscopic scaling effect and enhance the realistic VR experience.

Inventive Principle:

Principle #3Local quality

2Manufacturing precision

If selective scaling of specific objects is implemented, then the stereoscopic VR experience is improved, but the processing complexity increases

Engineering Contradiction:

Improvestereoscopic scaling accuracyVSAvoidprocessing complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by pre-processing the VR image to extract depth information and identify objects or regions before scaling operations. This preliminary segmentation and depth analysis are done in advance, allowing the actual scaling process to operate on pre-identified regions, thereby reducing the complexity of real-time selective scaling while maintaining stereoscopic accuracy.
