ML models were used to identify critical infrastructure components directly from inspection imagery. Importantly, beyond simple asset recognition, the system also now pinpoints anomalies, flagging issues such as missing equipment or structural deviations.

Advanced Image Analysis

A critical point in this process was the lack of ability to de-duplicate components visible across multiple images.

Utilizing clustering techniques derived from Siamese networks, the system groups similar elements based on visual features and spatial coordinates. This reduces redundancy, ensuring that each asset is uniquely cataloged, thus streamlining subsequent maintenance workflows.

Beyond simple visual analysis, this solution brings precision to quality control processes. It assesses image quality using advanced Deep Bilinear Convolutional Neural Networks (DBCNN), providing a perceptual quality score that helps determine the suitability of images for further analysis.

By automatically filtering out poor-quality images—affected by factors like incorrect exposure, blurriness, or pixelation—the system ensures robust data input for subsequent analytical stages.

Semantic Segmentation

Parallel to its image analysis capabilities, the system capitalizes on LiDAR-generated point clouds to construct accurate, detailed maps of transmission line networks. By leveraging state-of-the-art 3D semantic segmentation algorithms, such as the Kernel Point Convolution (KPConv), the platform distinguishes terrain features, vegetation, and structural components with high fidelity.

This semantic segmentation not only facilitates the automated generation of precise network maps but also identifies critical distance anomalies—situations where the spatial arrangement of assets might compromise safety or functionality. The automatically generated network map offers users quick and intuitive visual markers for each geolocated asset, significantly improving operational efficiency during inspections.

To further enhance model robustness, particularly crucial for field applicability, the ML models incorporate sophisticated data augmentation methods. Techniques such as AugMix introduce controlled variations in training data, significantly improving the models' performance under diverse real-world conditions and reducing susceptibility to common image corruptions. This approach ensures consistent reliability, even when confronted with suboptimal inspection imagery.

The Role of AI

An essential aspect of the neural network approach adopted by this system is its explainability—transitioning AI from an opaque "black box" to a transparent "white box" model.

Through specialized visualization techniques, users gain insights into exactly what features and regions within an image the neural network focuses on during asset and anomaly detection. This visual interpretation not only builds trust but allows developers to refine algorithms, improve network robustness, and take corrective actions based on clearly understood model behaviors.

The ability to automatically generate and visualize detailed network maps is a significant leap forward in infrastructure management.

These maps, created from LiDAR data, provide comprehensive insights into the layout and structure of transmission lines and their surroundings.

Each geolocated support, such as poles or secondary cabins, is marked clearly, facilitating quick and accurate identification. This functionality is particularly valuable in managing complex networks, providing clear, actionable information for operational teams, even in geographically challenging environments.

Transforming the inspection process

The platform’s superiority is further highlighted through direct comparison with traditional methods. Traditionally, inspections have relied extensively on manual processes involving visual checks conducted either from the ground or via aerial methods. These methods often suffer from inconsistencies, errors due to human factors, and limited scalability. By contrast, the AI-powered system provides greater accuracy, consistency, and speed, significantly reducing the scope for error and ensuring more reliable outcomes.

Additionally, the AI-driven approach enables automated verification of inspections performed by external contractors. This comparative analysis capability ensures higher levels of oversight, compliance, and quality control, reducing reliance on manual, labor-intensive verification methods. The platform’s semi-automatic comparison algorithms are particularly valuable in confirming the accuracy of external inspection results, enhancing accountability and quality assurance.

Moreover, the advanced image quality assessment tools within the platform ensure compliance with stringent inspection standards, automatically identifying images that do not meet the required criteria for clarity, exposure, or composition.
