Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data capture and labeling is performed for numerous object types, then recognition model training can be achieved, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically capturing images across multiple environments and performing labeling before model training begins. The image capturing device collects training images in advance, and the labeling device prepares annotations beforehand, eliminating the need for manual data preparation during the training process and significantly reducing training time while maintaining accuracy.
Solution Approach 2:
The system uses virtual rendering technology to generate synthetic training images that copy real-world object appearances. These rendered images serve as substitutes for actual captured images, allowing the model to be trained on diverse object types without requiring extensive manual photo collection and labeling for each object type.
2Adaptability or versatility
If recognition models are trained for huge number of object types, then comprehensive recognition capability is achieved, but the acquisition of sufficient image data and labeling requires large amount of time and labor
Solution Approach 1:
The system implements a universal data collection and labeling framework that handles multiple object types simultaneously. The image capturing device is configured to capture images of various object types across different environments using统一的 parameters and settings. The labeling device applies consistent labeling rules across all object types, enabling comprehensive object type coverage without proportionally increasing data preparation effort.
Solution Approach 2:
Virtual rendering technology generates synthetic images that replicate the appearance and characteristics of diverse object types. This copying approach allows the system to achieve comprehensive object type coverage by rendering various object categories without needing to manually capture and label images for each specific object type, significantly reducing data preparation effort.
3Measurement precision
If images are captured under specific background environments, then training data can be obtained, but recognition accuracy deteriorates when applied to different background environments
Solution Approach 1:
The system dynamically adjusts image capture parameters and environmental conditions during data collection. The image capturing device is configured to capture images across multiple different background environments, lighting conditions, and angles. This dynamic approach ensures that the training data includes diverse environmental variations, enabling the recognition model to maintain high accuracy when deployed in different background environments rather than being restricted to specific conditions.
Solution Approach 2:
The system changes multiple parameters including background environment, lighting conditions, camera angles, and object positions during image capture. By systematically varying these parameters across different capture sessions, the training dataset incorporates diverse environmental conditions. This parameter variation approach enables the recognition model to learn robust features that generalize well to different background environments, improving both recognition accuracy and environmental adaptability.
