Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a projector and camera are used to establish a structured light detection system, then 3D information about objects can be obtained, but the system requires PC processing and cannot directly obtain 3D information
Solution Approach 1:
The patent integrates the projector, camera, and image processing module into a single integrated detection device. The controller synchronizes the projector and camera operations, and the image processing module directly processes captured images to obtain 3D information without requiring external PC processing, thus merging multiple independent components into one unified system that maintains measurement precision while reducing system complexity
Solution Approach 2:
The integrated detection device performs self-processing of images through the onboard image processing module. The system captures structured light patterns, processes the images internally to extract 3D information, and outputs results without needing external PC assistance, enabling the system to serve itself and eliminate the dependency on external processing equipment
2Measurement precision
If a projector and camera are used to establish a structured light detection system, then 3D information about objects can be obtained, but detection efficiency is reduced due to PC processing requirements
Solution Approach 1:
The patent integrates the projector, camera, and image processing module into a single integrated detection device. The controller synchronizes the projector and camera operations, and the image processing module directly processes captured images to obtain 3D information without requiring external PC processing, thus merging multiple independent components into one unified system that maintains measurement precision while reducing system complexity
Solution Approach 2:
The integrated detection device enables continuous and real-time 3D information acquisition by synchronizing the projector and camera operations through the controller. The image processing module continuously processes captured images without interruption or external processing delays, maintaining a continuous workflow that improves detection efficiency and productivity
3Device complexity
If ordinary image acquisition devices are used, then device simplicity is maintained, but only two-dimensional information about objects can be obtained
Solution Approach 1:
The patent integrates the projector, camera, and image processing module into a single integrated detection device. The controller synchronizes the projector and camera operations, and the image processing module directly processes captured images to obtain 3D information without requiring external PC processing, thus merging multiple independent components into one unified system that maintains measurement precision while reducing system complexity
Solution Approach 2:
The patent transforms the detection capability from two-dimensional to three-dimensional by integrating structured light projection with image capture and processing. The projector displays structured light patterns that encode depth information, the camera captures these patterns, and the image processing module decodes them to extract 3D information, thereby adding a depth dimension to the acquired object information
