Study Notes
Laser Scanning - Modeling and Interpretation
- Topics covered in this course include laser scanning basics and applications, transformations and estimation, registration of datasets, segmentation and feature extraction, classification, Markov chain Monte Carlo and high-level reconstruction, and neural networks in laser scanning.
Aerial Laser Scanning
- Aerial laser scanning uses airborne laser scanners to capture 3D point cloud data.
- Examples of aerial laser scanners include Optech ALTM, Teledyne Optech Galaxy, and Riegl VQ-1560 II.
- Point cloud data can be used to create 3D models of cities, such as the Hannover main station example.
- Aerial laser scanning can be mounted on different platforms, including fixed-wing aircraft, helicopters, gyrocopters, and UAVs/drones.
Terrestrial Laser Scanning
- Terrestrial laser scanning uses ground-based laser scanners to capture 3D point cloud data.
- Terrestrial laser scanners can be classified as active, non-triangulating systems.
- Examples of terrestrial laser scanners include Leica, Faro, Riegl, and Z+F.
- Hybrid measurement systems combine laser scanning and image sensors to capture more detailed data.
Mobile Laser Scanning
- Mobile laser scanning uses vehicles equipped with laser scanners to capture 3D point cloud data while moving.
- Examples of mobile laser scanning systems include StreetMapper, Optech Lynx, and Riegl VMX-2HA.
- Mobile laser scanning can be used for mapping large areas, such as cities, and can capture detailed data, including point clouds and images.
Laserscanning in Robotics
