Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional three-dimensional reconstruction algorithms are used for transparent objects, then the algorithms can process non-transparent objects effectively, but the data acquisition reliability deteriorates due to complex reflection and refraction
Solution Approach 1:
The patent segments the light transport process into multiple discrete views by rotating the transparent object on a turntable to capture images from different angles. This segmentation allows the complex refraction and reflection processes to be analyzed separately in each view, improving data reliability while managing system complexity through systematic multi-view acquisition
Solution Approach 2:
The patent transitions from single-view to multi-view imaging by adding the rotational dimension. The turntable rotates the transparent object to capture images from multiple angular positions, effectively adding a temporal/angular dimension to the data acquisition process. This dimensional expansion enables reliable reconstruction by capturing light ray correspondences that cannot be obtained from a single viewpoint
2Measurement precision
If conventional algorithms are applied to transparent objects, then the processing flow remains simple, but the measurement precision deteriorates due to ineffective data acquisition
Solution Approach 1:
The patent performs preliminary action by capturing multiple views of the transparent object before reconstruction. The turntable rotates the object to predetermined angular positions, and images are captured at each position. This preliminary multi-view data acquisition ensures that all necessary light ray correspondence information is collected before the actual three-dimensional reconstruction process, improving measurement precision
Solution Approach 2:
The patent maintains continuity of useful action by systematically rotating the object through multiple angular positions and continuously capturing images at each position. This continuous multi-view data collection ensures uninterrupted acquisition of light ray correspondences, improving reconstruction precision while optimizing the balance between data quality and acquisition time
