Solution Approach 1:

The patent applies color segmentation to divide the 2D image into multiple color-based regions or segments. This segmentation allows the system to identify and extract objects based on their color characteristics, improving object extraction accuracy while managing processing time through efficient segmentation algorithms.

Inventive Principle:

2Measurement precision

If depth maps are generated using stereo pairs with common point correlation, then depth information accuracy is improved, but processing complexity and time increase

Engineering Contradiction:
Improvedepth information accuracyVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts and utilizes only the essential common points between stereo images for depth map generation, rather than processing all image data. This extraction approach maintains depth information accuracy while significantly reducing processing complexity and time requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs partial depth map generation by focusing on critical regions and common points rather than complete image processing. This partial action approach achieves sufficient depth accuracy without the full processing complexity of traditional stereo pair methods.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If Bezier curves are used to define object outlines, then processing efficiency is improved, but outline accuracy decreases

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent dynamically adjusts the number and positioning of Bezier curve points based on object complexity and required accuracy. For simple objects, fewer points are used for efficiency, while complex objects receive more points for accuracy, creating a dynamic balance between processing efficiency and outline accuracy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies different levels of Bezier curve detail to different regions of the image based on local object characteristics. High-detail curves are applied where needed for accuracy, while simplified curves are used where efficiency is prioritized, achieving local optimization of both productivity and precision.

Inventive Principle:
Principle #3Local quality
