Stereo Image Disparity Packet Structure for Safe 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereoscopic image transmission methods fail to ensure that disparity angles for nearest and farthest object positions are within a safe range for viewer health, and struggle to maintain consistent perspective when overlaying graphics onto images in three-dimensional space.
Innovation Solution
A data packet structure is introduced, where disparity information is inserted into the content portion and identified in the header portion, allowing for efficient transmission of disparity data, and the data packets are transmitted in increments of video field segments or GOPs, ensuring accurate and consistent disparity adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If disparity information is transmitted without structured data packets, then transmission simplicity is maintained, but disparity angle control precision deteriorates
Solution Approach 1:
The transmission data is segmented into structured data packets with distinct header and content portions. The header contains identification information for disparity information type, while the content contains the actual disparity data. This segmentation enables precise control of disparity angles by allowing the receiver to correctly identify and process different types of disparity information (minimum, maximum, or representative values) for nearest and farthest objects.
2Reliability
If graphics are overlaid without disparity information, then rendering simplicity is maintained, but three-dimensional perspective consistency deteriorates
Solution Approach 1:
Disparity information for graphics is prepared and transmitted in advance along with the image data. The data packet structure includes identification information that allows the receiver to recognize that disparity information applies to overlay graphics. This preliminary preparation ensures that when graphics are overlaid on stereoscopic images, they automatically inherit the correct three-dimensional perspective without requiring complex real-time calculations.
3Object-affected harmful factors
If disparity information is not transmitted, then transmission data volume is reduced, but viewer health safety deteriorates
Solution Approach 1:
Only essential disparity information is extracted and transmitted through the structured data packet system. The identification information in the header allows the receiver to distinguish between minimum disparity information (for nearest objects), maximum disparity information (for farthest objects), and representative disparity information. This selective extraction ensures viewer health safety by transmitting only the critical disparity parameters needed to keep disparity angles within safe ranges, rather than transmitting all possible image data.
