Researchers have developed a new method for extracting rail tracks from 3D point clouds using a fully convolutional recurrent neural network. This approach, trained on synthetic data, preserves full spatial resolution and enhances per-pixel quality for accurate track extraction. The process involves rasterizing track points, applying the neural network to clean the data, and then using morphological operations and smoothing techniques to refine centerlines. The method ultimately transfers 3D lidar information to 2D polylines, enabling the extraction of rail top and track centerlines with minimal manual intervention. AI
