Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustments are used to capture stereo video images, then the system can operate with simple hardware, but the quality of parallax settings deteriorates due to user experience limitations and time consumption
Solution Approach 1:
The system performs self-diagnosis and self-adjustment of parallax settings by automatically analyzing the captured stereo video images and adjusting the capture device parameters without requiring manual intervention from the operator
Solution Approach 2:
The system implements a feedback loop where the quality of captured stereo images is evaluated in real-time, and the parallax settings are automatically adjusted based on this feedback to maintain optimal quality standards
2Measurement precision
If a stereo video monitor is used to check image quality in real-time, then the user can detect parallax issues, but the small monitor screen size makes it difficult to detect certain undesired parallax that appears in large screens
Solution Approach 1:
The patent replaces the mechanical/visual inspection method using a small monitor with an automated computational analysis system that processes the captured images to accurately detect and measure parallax parameters, substituting human visual judgment with algorithmic analysis
3Ease of manufacture
If conventional stereo video capture systems are used, then the hardware requirements are simple, but the system requires significant manual corrections and repeated attempts to achieve reasonable quality
Solution Approach 1:
The system performs preliminary analysis of the capture parameters and automatically adjusts parallax settings before the actual video capture process, ensuring optimal settings are in place beforehand to avoid the need for repeated capture attempts and post-processing corrections

AI summary
A method is provided for a stereo video capture system. The stereo video system includes a stereo video monitor, a control platform, and a three-dimensional (3D) capture imaging device. The method includes capturing at least a first image and a second image, with a parallax between the first image and the second image based on a first parallax configuration. The method also includes receiving the first and second images; and calculating a value of at least one parallax setting parameter associated with the first and second images and corresponding to the first parallax configuration. Further, the method includes determining whether the value is within a pre-configured range. When the value is out of the pre-configured range, the method includes converting the first parallax configuration into a second parallax configuration. The method also includes sending, the second parallax configuration to the 3D imaging capture device, and adopting the second parallax configuration in operation.
