Article Highlights:  The use of Mobile Laser Scanning for collecting highway conditions such as pavement markings is increasing. Since pavement markings are made intentionally reflective their return intensity can be used to auto-extract them from the point cloud. Extracting them can be a challenge given the accuracies of current MLS systems (cm-level), relative to the thickness of the markings (mm-level). […]

Where Are We With Feature Extraction?

Feature extraction and automated feature extraction were the main topics of discussion at conferences and during presentations about five years ago. Now, focal plane LiDAR and UAV’s are all the buzz. Feature extraction is still a vital part of what we do and are trying to do better. Where are we with feature extraction and how have we progressed? Companies […]
