Artificial intelligence (AI) can identify landslides and other geological changes that threaten electricity transmission towers, potentially helping operators intervene before infrastructure fails, according to research in the International Journal of Power and Energy Conversion.
The researchers focused on change detection, a remote-sensing technique that compares images of the same location taken at different times to identify disturbances in the landscape. While widely used in environmental monitoring and disaster assessment, such systems have not historically worked well with landslides, because disaster datasets are limited.
The new model analyses satellite or drone images captured before and after a disaster using a twin-network architecture, in which two linked AI systems process and compare images from different periods. It also uses a visual foundation model, a large AI system pre-trained on remote-sensing imagery, to provide broader information about terrain and landscape features.
A key component of the approach is an attention-based alignment module, which allows the AI to focus on relevant information. Here, the module filters out irrelevant differences, such as seasonal vegetation changes or lighting variations, while highlighting structural changes linked to hazards.
Tests on a real disaster dataset showed the system outperformed several recent change-detection methods.
