Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of panoramic content is raised, then the immersion feeling of viewers is improved, but the data size becomes excessively increased
Solution Approach 1:
The panoramic image is segmented into a central high-definition region (from planar coordinate system) and surrounding low-definition regions (from spherical coordinate system). This segmentation allows different resolution levels in different areas, maintaining immersion in the central view while reducing overall data size.
Solution Approach 2:
Different quality levels are applied to different regions of the panoramic image. The central region where the viewer's attention is focused maintains high definition, while peripheral regions use lower definition. This local quality differentiation preserves immersion where needed while reducing total data size.
2Quantity of substance
If the resolution is lowered to prevent an excessive increase in the size of the panoramic content, then the data size is controlled, but the immersion feeling of viewers is deteriorated
Solution Approach 1:
The patent applies different quality levels to different spatial regions: high definition in the central planar region and low definition in the surrounding spherical regions. This ensures that the central viewing area maintains sufficient resolution for immersion while the overall data size remains manageable.
3Measurement precision
If high-definition image data of planar coordinate system and low-definition image data of spherical coordinate system are integrated, then the immersion feeling is maintained, but the technical complexity of alignment and stitching increases
Solution Approach 1:
The patent uses an intermediary coordinate transformation process that converts spherical coordinate system data to planar coordinate system data through feature point matching. This intermediary step simplifies the integration by establishing a common reference frame between the two coordinate systems, making alignment and stitching more manageable.
Solution Approach 2:
The patent replaces complex mechanical alignment procedures with automated image processing techniques, including feature point detection, coordinate transformation, and algorithmic stitching. This substitution reduces manual intervention and simplifies the overall processing complexity while maintaining integration quality.
