Engineering Contradiction Analysis
1Measurement precision
If motion control and exposure settings are manually adjusted for generating training datasets, then image quality can be improved, but the process complexity and time consumption increase significantly
Solution Approach 1:
The system enables self-service by having the capturing device automatically execute motion sequences and adjust exposure parameters without manual intervention. The processor controls the motion generator to sequentially apply first motion for blur image capture and second motion for sharp image capture, while automatically setting capturing parameters including exposure time, thereby eliminating the need for manual adjustment and reducing process complexity
Solution Approach 2:
The patent replaces manual mechanical control with an automated electronic control system. The processor electronically controls the motion generator to execute precise motion sequences and electronically adjusts capturing parameters such as exposure time, substituting manual mechanical operations with automated electronic control to reduce complexity and time consumption
2Measurement precision
If multiple capturing parameters are adjusted to generate both blur and sharp images, then training dataset quality improves, but the time required for data collection increases
Solution Approach 1:
The system implements continuous operation by sequentially executing motion sequences and capturing images without interruption. The motion generator continuously applies first motion followed by second motion in a seamless sequence, and the capturing device continuously captures images with different parameters, eliminating idle time and maximizing useful action duration to reduce overall data collection time
Solution Approach 2:
The patent applies preliminary action by pre-programming the motion sequences and capturing parameter settings before data collection begins. The processor is configured with predetermined motion sequences and parameter settings, allowing the system to automatically execute optimized capture operations without trial-and-error adjustments, thereby reducing data collection time while maintaining high training dataset quality
3Measurement precision
If exposure time is extended to improve image quality, then image detail is enhanced, but motion blur increases
Solution Approach 1:
The patent segments the capturing process into distinct phases: first motion for blur image capture with longer exposure time to capture motion blur characteristics, and second motion for sharp image capture with shorter exposure time to minimize blur. This segmentation allows each phase to optimize for its specific purpose, simultaneously obtaining both motion blur and sharp images without compromise
