Terrestrial 3D Laser Scanning by Drone

DAY 1:

Discovering the 3D Laser Scanner

Getting familiar with the equipment, its characteristics, limitations, and maintenance;
Handling the scanner;
General principles of 3D scanning (instrument positioning, target positioning, resolution choices);
Learning different methods for field surveys.

Acquiring Data with a 3D Laser Scanner

Setting up with or without targets;
Capturing point clouds in the field;
Pre-aligning positions on the tablet (depending on the equipment);
Exporting data.

DAY 2:

Visual or Target-Based Assembly

Automatic assembly after import;
Mastering advanced assembly parameters (sub-sampling percentage, number of iterations, maximum errors);
Automatically adding constraints;
Merging assemblies without a common target.

Advanced Cleaning, Segmentation, and Measurements

Cleaning before assembly;
Working with a Limit Box;
Sampling the point cloud;
Semi-automatically cleaning surfaces;
Taking measurements, distances from a point to an axis.

DAY 3:

Assembly with Drone Data from Photogrammetry

Importing data into the software.
Assembly method with and without targets.
Checking the quality of data assembly.
Cleaning and clipping the point cloud.
Exporting data and exchanging with other platforms.
Managing databases.
