I just recently started doing photogrammetry as a cinematographer and I have to say thank you for such a cool channel and helpful content! I'm surprised there aren't many views here.
I have used Polycam quite a bit. I am currently not subscribed anymore but I will say this - if you’re out scanning this is a fast way to get results before you return back into the office. also, when I have shot three or four have them processed all at once. So I get it a quick feedback for the things I am shooting, eventually getting the chance to re-shoot or shoot more images if I need them. I would consider that a pro for somebody shooting, professionally, knowing that you can get better quality once you’re returned to the office. It’s also nice that you can have a look at your scans from several devices(phone/iPad/computer) Keep up the good work. Kind regards.
Good point. If you're using your phone to shoot images then it's a big plus to get quick feedback. For sure. But then we're going back to the "who's it for" question. If you're shooting professionally you will probably choose to use a camera to get the maximum quality possible. And then we're back to square one. We lose the quick feedback benefit of Polycam. I guess it's doable if you transfer the camera images to the phone on location. But it will be clunky.
@@marvelousdecay you’re right, of course. I did transfer photos from camera to iPad to see if it works but then of course it slows down the process. I got the most benefit out of it when I was on vacation scanning things without a lot of equipment still got some nice assets out of it, once I have processed things with PhotoCatch at home, previews were very helpful while I was traveling. So I may just renew my subscription for my next vacation or a longer trip.
Dimitris, great video! I have a question for you. Suppose that I want to create a 3d model of an archaeological ruin (i.e. an old bridge, old building). Do you think that the combination of Polycam (for details and low points) and a drone for the high points is enough? I am usually using the photos inside Metashape to create the mesh file. Is that the best solution?
Hey there! As long as there's some overlap, combining your phone and drone photos will work fine. I would suggest the following: Take regular RAW images with your phone (instead of using Polycam) and then use Metashape to combine them with your drone photos. You will get better results that way. Hope that helps!
@@marvelousdecay I know that's the best way, but I bought the premium version of Polycam in order to take 2000 shots quickly!! Then I send to my Mac the images (.heif files) and combine with the jpegs from the drone to create a sum of images to align. What do you think of that?
Impressive that Photocatch is free. I don't have a Mac, so I can't use it. I guess it manages to process locally? Perhaps that will be an option on iPhones in another year or two. As for Polycam, I do think that it's targeting hobbyists, but it's also maybe carving out its own niche by having an asset library where people can share and "like" each other's scans, etc. I don't think it's intended for creating movie or big-budget assets... though it would be cool if it had a pro-tier subscription model for that. Turn the "raw" setting into the "high" setting and unlock a REAL raw with a bigger fee. I'd consider subscribing at least for a few months to create high-quality scans of things, just as a hobbyist, if AR/VR headsets ever really start to take off. I suspect that is where they're really hoping to carve out a market.
@@marvelousdecay What would you recommend as the best photogrammetry app/software to convert images to a high quality, very accurate point cloud? I have a pretty good 3D laser scanner, but even that doesn't create a point cloud with say .5mm accuracy. You have to spend about $30,000 to get that kind of a scanner. I'm looking into photogrammetry with good software as an alternative to an expensive 3D scanner. Any thoughts on this?
Metashape is really good and also Apple's photogrammetry SDK is good as well. If you own a PC you can check Reality Capture. It's supposedly really good but I haven't tried it since I'm on a mac.
Mainly Photocatch (the desktop version), the app you see in the tests of the video. It’s Mac only since it uses Apple’s SDK but it’s a fast and easy solution.
you can definitely scan it. It'll scan without any problems. As for revealing text I'm not so sure. It really depends on the state of the marker. I would say to increase your chances of getting good data use a camera instead of your phone.

Great to hear you love the content. Spread the word! :D

What iPhone model is he using
underrated channel fr

Is there a way to measure distance in any of these apps? Are the scanned objects to scale when exported as object or STL files?
I have Polycam and measuring is one the best features of the app/program.
Thanks, Dimitris...excellent review and very helpful
You're welcome!

Please mention those good and free alternatives of Polycam

Is photocatch free?
@@looeehg2490 As I said already yes it's free.
I was just clarifying...
@@marvelousdecay wow, I missed the information that Photocatch is free. Thank you for the answer
in your opinion could you scan a Grave marker that has been worn by time to reveal any text? Thanks, Mike
you can definitely scan it. It'll scan without any problems. As for revealing text I'm not so sure. It really depends on the state of the marker. I would say to increase your chances of getting good data use a camera instead of your phone.
@@marvelousdecay Thanks so much!
Ευχάριστο, Δημήτρης!
Για assets δεν είναι τόσο καλό πράγματι, αλλά για για αρχιτεκτονική και χώρους είναι απίστευτο
i love this channel
Fun fact, Polycam is not an iPhone app 😂.
It's for almost everyone
and if you are not stuck with Apple products, you have the freedom of using this app in Android devices from other companies
Not with lidar
