How Edge AI Works on Drones
Edge AI equips drones with the ability to make instant, onboard decisions, functioning as a self-reliant anomaly detection system that doesn't depend on ground-based networks.
Data Collection from Drone Sensors
Today's industrial drones are outfitted with a variety of sensors, each contributing to a detailed understanding of their environment. Thermal cameras detect heat signatures, helping identify overheating equipment or energy inefficiencies. LiDAR sensors create accurate 3D maps by measuring distances with laser pulses. Additionally, 360-degree cameras provide full visual coverage, and multispectral cameras uncover details beyond human vision.
The growing sophistication of these technologies is reflected in the global AI in drones market, which is projected to expand from $14.5 billion in 2023 to $84 billion by 2030, with an annual growth rate exceeding 28.5%. A key enabler of this capability is sensor fusion, where data from multiple sensors is combined to improve decision-making accuracy and reduce errors. This integrated data is processed onboard the drone, enabling split-second decisions.
Processing Data and Extracting Features
Once collected, the raw sensor data is processed by onboard systems to generate actionable insights. AI algorithms analyze this data to detect patterns that indicate abnormalities. For example, thermal imaging might highlight temperature spikes signaling equipment malfunctions, while visual data could reveal physical irregularities that suggest mechanical issues.
By processing data directly on the drone, edge AI ensures faster, more accurate anomaly detection compared to systems that rely on remote analysis. This localized processing allows drones to quickly adapt to dynamic conditions, such as rerouting around obstacles or focusing sensors on areas of concern. Frameworks like TensorFlow Lite and PyTorch Mobile are designed to run lightweight AI models efficiently on drones with limited computing power. These systems enable drones to deliver precise, real-time insights.
Applying AI Models for Anomaly Detection
The final step involves deploying advanced AI algorithms to differentiate between normal operations and potential problems. For instance, Isolation Forest models are adept at spotting single-point anomalies like sudden temperature changes or unusual vibrations. Meanwhile, LSTM (Long Short-Term Memory) neural networks excel at identifying time-based patterns, such as gradual changes occurring over minutes or hours.
One example of this in action is a CNN model that achieved 99.37% accuracy in detecting chainsaw sounds, showcasing how tailored AI models can precisely identify specific anomalies. Another example is the DroneCrypt IFF system, which combines multiple approaches to achieve a false positive rate below 0.01% and a false negative rate under 0.001%.
Autoencoder models are also widely used to detect mechanical issues by analyzing flight data for irregularities that may signal equipment problems. These AI-powered systems allow drones to assess their surroundings and respond instantly. A practical application of this technology is seen in the European Border and Coast Guard Agency (Frontex), which uses real-time anomaly detection in its drone surveillance systems. This has significantly enhanced their ability to identify unauthorized border crossings and smuggling activities.
AI Models and Technologies for Anomaly Detection
Edge AI thrives on specialized algorithms designed to quickly process various sensor data types and identify potential issues. Each AI model has its strengths, from detecting sudden equipment breakdowns to spotting gradual performance declines.
Isolation Forest for Sudden Anomalies
Let’s start with Isolation Forest, an algorithm tailored for identifying unexpected, discrete anomalies. It works by directly isolating unusual data points rather than defining what is normal. This makes it particularly effective for analyzing complex datasets like LiDAR scans or thermal images. The principle behind it is straightforward: anomalies are rare and distinct, so they’re easier to isolate.
Isolation Forest creates isolation trees through recursive partitioning, where anomalies result in shorter path lengths. By calculating average path lengths, the algorithm assigns anomaly scores - values closer to 1 indicate clear outliers.
This model is especially useful in drone applications due to its efficiency. It processes data linearly and requires minimal memory, as it works with smaller data subsets. Additionally, it avoids reliance on distance metrics, which can falter with complex sensor data, and it doesn’t assume any specific data distribution. Operators implementing Isolation Forest should fine-tune settings like the contamination parameter and consider using feature selection to minimize noise from sensor data.
LSTM for Time-Based Patterns
While Isolation Forest handles sudden anomalies, Long Short-Term Memory (LSTM) networks are ideal for analyzing changes that occur over time. LSTM models excel at capturing temporal dependencies, making them perfect for monitoring evolving patterns in drone operations. They can track how equipment performance shifts over time by modeling sequential data and contextual information.
LSTM networks have demonstrated impressive results, achieving false positive rates below 0.01% and false negative rates under 0.001%. They also outperform traditional Recurrent Neural Networks (RNNs), which often struggle with vanishing gradient issues, limiting their ability to retain long-term patterns.
Leveraging Multi-Sensor Data
For a broader perspective, combining data from multiple sensors can create a more comprehensive understanding of the environment. Multi-sensor data fusion integrates inputs from thermal cameras, LiDAR, visual sensors, and RF detectors. This approach capitalizes on the strengths of each sensor while compensating for their individual weaknesses.
In March 2025, Palladyne AI and Red Cat showcased this concept using Palladyne's Pilot AI software on Red Cat's Teal 2 drones. The drones worked together to locate and track a vehicle, seamlessly switching from camera feeds to radio signal detection when the vehicle disappeared from view. This was achieved using existing hardware.
"We reduce the cognitive load on a single operator using a six-inch screen with feeds from nine drones. It has to be augmented with AI."
– Geoff Hitchcock, Red Cat
The system employs AI-driven sensor fusion engines to combine outputs intelligently, generating actionable insights complete with threat levels and confidence ratings. Techniques like Kalman filtering, complementary filtering, and adaptive weighting algorithms process multiple data streams in real time. Recent tests highlighted an adaptive weighting algorithm that achieved 94.2% accuracy, 93.7% robustness, 100% real-time performance, and 95.6% consistency. This fusion method not only improves detection sensitivity and range but also significantly reduces false alarms.
"The software autonomously enables improved situational awareness."
– Matt Vogt, Chief Revenue Officer of Palladyne AI
To further enhance intelligence, the system integrates reinforcement learning, sensor fusion, and game theory techniques. When one drone needs additional data, it automatically requests input from others in the network. This collaborative effort ensures detailed monitoring across dynamic environments, while effectively filtering out noise that could lead to false alerts.
