Engineering Contradiction Analysis
1Manufacturing precision
If spherical images are captured and transmitted using conventional image processing methods, then the images can be viewed online, but distortion occurs and data efficiency is reduced
Solution Approach 1:
The spherical image data is segmented into multiple resolution levels, with the first resolution level containing high-frequency components and the second resolution level containing low-frequency components. This segmentation allows selective transmission and processing of different data portions, improving both image quality and data efficiency by transmitting only essential information at each resolution level.
Solution Approach 2:
Different processing methods are applied to different portions of the image data based on their characteristics. The first resolution level (high-frequency) and second resolution level (low-frequency) are processed differently, with the destination apparatus performing image processing based on image processing setting information specific to each level, optimizing both quality and efficiency locally.
2Productivity
If image processing is performed at the source apparatus, then processing speed is improved, but device complexity increases
Solution Approach 1:
The source apparatus performs preliminary image processing to generate processed image data in multiple resolution levels before transmission. By pre-processing the image data and organizing it into structured resolution levels with associated setting information, the system reduces the processing burden on the destination apparatus and improves overall processing speed without significantly increasing destination device complexity.
Solution Approach 2:
Image processing setting information acts as an intermediary that guides the destination apparatus in performing appropriate image processing on the transmitted data. This intermediary information enables the destination apparatus to efficiently process the image data without requiring complex processing algorithms, thus improving processing speed while maintaining manageable device complexity.
