Intro to 3D Zephyr Webinar & FAQs

Recently we held a seminar that introduces how 3DF Zephyr workflow is used to create highly representative 3D models and 2D ortho mosaics of the cultural heritage around us. You can watch this below.

Naturally there are a few questions that customers may ask. We thought it would be helpful to collate these on one page for ease.

Does the programme also work with Mac, or just Windows?

Presently just Windows is supported

Can you run bootcamp on your mac and install windows to run it?

Bootcamp will work but may not exploit hardware such as graphics cards

Is it easier on hardware than Metashape?

All photogrammetry software is demanding. So far, no hard metrics or comparative testing has been done. Anecdotally, some steps are slower, some faster. End result is about the same!

When setting control points, do the error margins suggest that there is an error in the mesh, or errors in where we’re clicking the control points?

The errors can indicate two issues; user error when placing points or weak camera bundle (not mesh) alignment.

Is there any limitation on number of images to process?

No limit in Zephyr. 500 camera limit in Zephyr Lite…we are lobbying hard to remove that. Please use the contact us page and let us know your thoughts

Does the lite version support control points?

No, the Lite version does not allow scaling. However, the project can be saved and loaded in full Zephyr, and vice versa.

When I capture large areas by video it comes with drift, Is there a solution for that?

We are always hesitant to recommend video as a source for photogrammetry.

Is it possible to estimate image quality?

Yes, image quality can be estimated.

Can we export as point cloud?

Yes, and in multiple formats. A separate application (included with Zephyr) is geared around point cloud alignment.

Is there need – or the tools – to “clean” the sparse cloud (aka Gradual Selection in the “other” software)?

Recursive optimisation steps are typically not required.

What is the best hardware to photogrammetry large industrial areas?

A drone with a high res camera with mechanical shutter and RTK positional correction would be a good start.

How much does it cost? Is there an educational option available?

The products are in our shop and yes there is academic/educational pricing too.

Is the software web/internet dependent? Or is local processing (no internet) possible?

Local processing – not a problem. Web link optional.

Is the software able to be moved between different render machines?

Yes, the license can be moved by deregistering one pc and moving to another

Where does 3DF originate from?

3DF are based in Verona, Italy.

AccuPixel’s shop is now open for 3DFlow.

If you have any further questions that aren’t answered here – please do not hesitate to contact us – we would be happy to help.
