A Bidirectional Analysis Method for Extracting Glacier Crevasses from Airborne LiDAR Point Clouds

A Bidirectional Analysis Method for Extracting Glacier Crevasses from Airborne LiDAR Point Clouds

A crevasse is an important surface feature of a glacier. This study aims to detect crevasses from high-density airborne LiDAR point clouds. However, existing methods continue to suffer from the data holes within the crevasse region and the influence of the undulating non-crevasse glacier surfaces. T...
