Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional image processing techniques or simple machine learning models are used for anomaly detection, then the system is simpler and more cost-effective, but the detection accuracy and robustness deteriorate in complex agricultural settings
Solution Approach 1:
The patent transforms the anomaly detection approach by changing the fundamental parameter of the detection model from traditional image processing or simple machine learning to a deep neural network architecture. This parameter change enables the system to achieve high detection accuracy and robustness in complex agricultural settings with varying lighting, occlusions, and clutter, while still maintaining reasonable system complexity through efficient network design and training methods.
2Ease of manufacture
If camera-based anomaly detectors are used to capture rich visual information in a cost-effective way, then the cost is reduced, but the system fails to robustly and accurately detect a wide range of anomalies due to difficulty in handling varying lighting conditions, occlusions, and clutter
Solution Approach 1:
The patent changes the detection algorithm parameter from traditional image processing methods to a deep neural network, which fundamentally improves the system's ability to handle varying lighting conditions, occlusions, and clutter. This parameter change enables camera-based systems to achieve both cost-effectiveness and high reliability in detecting diverse anomalies in agricultural settings.
Solution Approach 2:
The patent implements a feedback mechanism where the deep neural network continuously learns from detected anomalies and adjusts its detection parameters. The system uses training data including images of anomalies to refine its detection capabilities, creating a feedback loop that improves reliability over time while maintaining the cost-effective camera-based approach.
3Loss of information
If anomaly detectors rely on data from LiDAR units, GNSS units, and radar units, then some information about the environment is obtained, but the accuracy, cost, and complexity are limited and many types of anomalies such as small objects, thin obstacles, or irregularly shaped features cannot be detected
Solution Approach 1:
The patent substitutes the mechanical sensor-based detection systems (LiDAR, radar) with an optical-based deep learning system. By replacing traditional mechanical sensing approaches with camera-based deep neural network analysis, the system achieves superior detection precision for small objects, thin obstacles, and irregularly shaped features while reducing overall system cost and complexity.

AI summary
A method of validating detected anomalies in an agricultural field includes gathering sensor data with one or more cameras, LiDAR units, and radar units and generating predicted anomalies based on the sensor data by applying an anomaly detection deep neural network to the sensor data. Sensor data is gathered at a second time and predicted anomalies are determined by applying the anomaly detection deep neural network to the sensor data acquired at the second time. The predicted anomalies at the second time is compared to the predicted anomalies at the first time to validate the predicted anomalies and generated a validated anomaly map. Related agricultural machines and systems are also disclosed.
