Engineering Contradiction Analysis
1Measurement precision
If LiDAR, GNSS, and RADAR units are used for anomaly detection, then detection coverage is improved, but system cost and complexity increase
Solution Approach 1:
The system segments the anomaly detection task by using different sensor types (LiDAR, GNSS, RADAR, cameras) for different aspects of detection. Each sensor handles specific detection requirements, dividing the complex detection problem into manageable parts that can be processed independently and then integrated.
Solution Approach 2:
The anomaly detection system is designed to perform multiple functions using a single integrated platform. The system can detect various types of anomalies (stones, structures, objects, power poles, trees, buildings, water bodies, humans, animals) using the same sensor suite and processing architecture, making the system universally applicable to diverse agricultural scenarios.
2Device complexity
If traditional image processing techniques are used in camera-based anomaly detectors, then system cost is reduced, but detection accuracy and robustness deteriorate
Solution Approach 1:
The system replaces traditional mechanical image processing techniques with deep learning-based computer vision algorithms. Neural networks automatically learn features from images without manual feature engineering, substituting complex mechanical processing with intelligent software-based processing that achieves superior accuracy.
Solution Approach 2:
The system changes the processing parameters by using deep learning models that can adapt to varying lighting conditions, occlusions, and clutter dynamically. The neural networks adjust their processing behavior based on input characteristics, allowing robust detection across diverse conditions without requiring manual parameter tuning.
3Device complexity
If simple anomaly detection systems are used, then system cost is reduced, but ability to detect moving anomalies and handle spatial relationships deteriorates
Solution Approach 1:
The system uses feedback mechanisms where anomaly detection results are continuously updated based on new sensor data and spatial relationships. The system processes sequential data from moving vehicles and anomalies, using feedback from previous detections to improve current and future detections, enabling accurate tracking of moving objects.
Solution Approach 2:
The system adds spatial and temporal dimensions to anomaly detection by considering the positions, movements, and relationships of multiple anomalies in three-dimensional space over time. This multi-dimensional approach enables the system to handle complex spatial relationships and dynamic environments that simple two-dimensional image processing cannot address.
