Brief report on workflow using MacBook Pro 15-inch (2019)

[smiller]

Hello everyone,

Attached is a brief summary report of a project completed using drone imagery for surveying 16 site locations. Many people have asked me about Apple computers running Metashape. I hope this helps give somewhat of a general idea for some of the Mac users out there.

Also, like many of us know, there are many factors that influence how the various steps in Metashape run. Please be aware that I mainly focused on collecting the times (as reported in Metashape) for running the photo alignment and dense cloud steps. 3D models were not required for this project so they were not built.

Feel free to ask any questions. Thanks.

Hello smiller,

Thank you for sharing this information.

Have you checked, if you are getting similar results in terms of alignment accuracy and quality of the further processing products, if 40 000 and 10 000 key / tie point limits are used for the image matching? I think 200 000 / 100 000 is not needed for the specified image resolution in the set and would slow down all parts of Align Photos stage.

Hi Alexey,

The higher photo alignment (200,000 / 100,000) increased the resolution and visual appearance of the orthomosaic images slightly. This is also something I thought about as well. I may re-run the models to compare times with the 40,000 / 10,000 settings.
