Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional image processing is performed to accurately aim the laser beam at specific portions of the target object, then the positioning precision is improved, but the operation complexity increases
Solution Approach 1:
The patent performs image processing operations (chromaticity space conversion, thresholding, contour detection) on the captured image before laser beam emission to pre-identify the characteristic portions and their coordinates. This preliminary processing allows the laser module to directly use the pre-calculated positioning information without requiring complex real-time processing during laser emission, thus improving precision while managing operational complexity.
2Measurement precision
If additional image processing is performed to accurately aim the laser beam at specific portions of the target object, then the targeting accuracy is improved, but the operation time increases
Solution Approach 1:
The patent extracts only the necessary information (coordinates of characteristic portions) from the full image processing pipeline. By focusing specifically on detecting contour points and calculating their coordinates in the image coordinate system, rather than performing comprehensive image analysis, the system achieves accurate targeting while minimizing the time consumed by image processing operations.
3Productivity
If the laser module directly emits laser beam without image processing, then the operation speed is improved, but the positioning precision deteriorates
Solution Approach 1:
The camera module captures the image and the processing module identifies characteristic portions and their coordinates before the laser module emits the beam. This preliminary positioning action provides the laser module with pre-calculated target coordinates, enabling fast and accurate laser emission without requiring complex real-time processing during the actual laser firing, thus maintaining both speed and precision.
