2: Basic Image Collection and How to Use Agisoft Metashape
IN THIS LESSON
Nicole Pedersen, Staff Researcher | Scripps Institution of Oceanography
Learning Objectives: Build on the knowledge gained in previous lesson (Introduction to Metashape) by demonstrating the process of model processing in Metashape.
Supplementary Videos: Agisoft Advanced Features
Dr. Arthur Gleason, Research Associate Professor at the University of Miami
These videos explore advanced features and tools in Agisoft Metashape to refine your 3D modeling skills. Learn to create essential products like DEMs, orthophoto mosaics, and mesh models; incorporate accurate scale using scale bars; address noisy reconstructions for cleaner outputs; and interpret camera calibration reports. Dr. Arthur Gleason provides practical insights and demonstrations to refine your 3D modeling skills.
Agisoft Advanced Features: Scale
This video addresses a crucial detail omitted in the previous video, "Agisoft Advanced Features: Products," adding scale to your model. After explaining the need for scale in his “How Did We Get Here” video, Dr. Gleason now dives into using scale bars in Metashape, demonstrating how to effectively incorporate scale into your models.
Student Question: Interpreting Agisoft Reports
In this video, Dr. Gleason answers a student’s question about the meaning of the camera calibration image found in the Agisoft Metashape report generated for each product. What are those colored lines? What do they represent? Why should I care about this? Dr. Gleason provides a comprehensive overview of what this figure means and how to interpret these plots.
Agisoft Advanced Features: Editing
This video tackles a common challenge in model building - handling noisy reconstructions. Dr. Gleason demonstrates two effective methods to improve the quality of your Metashape models by reducing spurious points.
Agisoft Advanced Features: Products
This video builds on the concepts covered in Chapter 2, demonstrating how to derive products from the dense point cloud, including a digital elevation model (DEM), an orthophoto mosaic, and a mesh model. These steps are universal to most photogrammetry software, though Metashape is used here as the example platform.
