New studies indicate photos taken both on the ground and using unmanned aerial vehicles (UAV) can be used to create accurate 3D models for volume calculation and visualization. This presentation will review the current UAV and terrestrial photographic and laser scanning technology being utilized for remote sensing, and demonstrate how ReCap 360 software processes and analyzes photography, traditional LiDAR (light detection and ranging), and laser scanning technology outputs. Resulting data sets are used in AutoCAD Civil 3D software to create surfaces and are analyzed in 3D for volume calculations, site, and building engineering drawing creation. They are then processed in Memento and brought into InfraWorks software to visualize the 3D mesh in real-world context. This class will review 3 studies comparing the accuracy of photographic differential parallax and traditional laser scanning captured by fixed wing UAV, quadcopters, and terrestrial laser scanning and survey equipment.
- Learn how to capture, process, analyze, and visualize data captured from UAV and terrestrial remote-sensing systems
- Learn how to use Recap 360, Memento, AutoCAD Civil 3D, and InfraWorks for data processing, analysis, and visualization
- Discover current UAV and terrestrial remote-sensing technologies by examining 3 separate studies and the accuracy results
- Discover where we are today and how this technology is shaping the future of reality capture
