Terrain segmentation with label bootstrapping for lidar datasets, case of doline detection
Aerial lidar scan of Slovenia with resolution 1 m^2 was used to segment out a large number of dolines, specific relief depressions that are a diagnostic feature of karst landscape with typical diameter of 42 m. This talk will cover data processing, label bootstrapping, TPU based model training and inference that was done to deliver a catalog of 472k segmented objects.
