LV-UAV-Guide | Creating High Quality Products

Outcomes

The module is intended to provide a solid overview of the extensive range of structure-from-motion (SfM) photogrammetry software and its use:

Identify which of the software packages provide good results and are cost effective.
Using the commercial software Agisoft Metashape, an optimized workflow for orthoimage generation will be demonstrated and practiced.
Optionally, this workflow is also explained and illustrated with the open source software OpenDroneMap.
Optional tutorials are available for special tasks.

Experiences

Metashape basic workflow

The Metashape software provides a very slim standard workflow with reasonable default values. This tutorial gives some additional explanations for the initial exercises to create an otho image and a point cloud.

basic mandatory

Metashape Ortho+ - optimized processing of RGB images

Metashape Ortho+ extension provides a set of tools for easy reproducibility of optimized generation of orthoimages and point clouds. It is a convenient extension of the standard tools and workflows.

advanced mandatory

Use Case Gisselberger Spannweite

The objective of this feasibility test is to evaluate the postulated workflow for its efficiency and applicability.The goal is to acquire and compute sufficiently accurate (< 2.5 cm) and reproducible orthoimages using low-cost mini-UAVs (< 250 g weight) with minimal effort.
