- How to create a 3D scan of an object using your cell phone camera and free software? We compare our free 3D scan to a professional scan of the same part. The Pro 3D scan was made with a 20.000 EUR 3D Scanner. Learn more at: holocreators.com/blog/3d-scan...
All software to do this tutorial is free. You don't need a special app for your phone, just the photos. The technique to create this 3D scan is called photogrammetry. Any commercially available camera can be used for this. Meshroom works best with an Nvidia GPU. There have been some problems with Meshroom, when not using a Nvidia graphics card, then you need to use “draft meshing”: github.com/alicevision/meshro...
Where is Meshroom saving the 3D files?
This question has been asked by many of you. Answer: When clicking the "Start" Button for the first time, Meshroom will ask you where to save the Cashe folder: normally it goes to C:/Users/Computer-name/AppData/local/Temp/MeshroomCashe
Software needed to follow this Tutorial:
Meshroom (to convert the photos into a 3D file):

Hello. Can you tell me, how I can scan something bigger. How I can scan a car? Thanks
This is such a good tutorial. No distracting music, no droning on about nothing...just well presented, useful information. This is how instructional content is done, folks. Subscribed.
Thanks Joe for the kind words.
Agreed! It's nice to have a detailed tutorial that isn't ruined by loud background music.
Totally agree! It was very clear to understand, and I appreciated that he mentioned the difference deviation average at the start too. Also subscribed from this. 👍 good stuff
Yep, I got way more than I expected from this.
Not only I learned how 3D scanning is done and that I can easily do it for free. I was handed the tools on a silver plate. And if I ever need better accuracy I know this is the company I will contact first.
This is how advertisement is done. Give something for free (great tutorial) and get user hooked.
Liked, subscribed, bookmarked and downloaded the video, same with their site, shared to friends.
I just wish more content creators followed this principle, so much filler in a lot of articles and videos.
Remember when you had to write numerous page essays in school or like they had a mandatory amount of words, so most people would write in a bunch of nonsense to fill up enough on their work to qualify the little bit of actually important substance?
Read articles online that have lots of dumb filler and look how they write it, it looks just like high-school all over again. Not a useful skill.
A 3D scanning company just made a video tutorial about how you don't generally need professional 3D scanning, and how using your phone and a bunch of free programs is more than good enough? This is immediately the best 3D scanning company I've ever seen
That shows real confidence in their abilities
Sure I love if more people get to 3d scan things. By the way we offer xray ct scanning too. I am working on a video how to do xray scanning at home ;-)
Thanks! I've done different kind of videos decades and it's good to see really pro-made tutorial as this is. Relaxing and clear explanations, no disturbing discomusic, no idiotic camera moving. Once again, thank you very much. I'm sure your company is also good and pro.
thank you
Thank you for making this video. This is the best quick start video for Meshroom I could find on CZcams. Subscribed!
thanks, glad you like it
A nice, calm tutorial. And a good way to promote your own company without pushing it too hard. Well done!
I appreciate that, Thank you Toby.
Great job on this tutorial comparison. I am currently in the market for my first 3D printer and plan to do some scanning as well. Thank you for posting this I will be watching more of your videos as I just subscribed. I think more traditional engineers like myself should learn 3D scanning and printing as additional tools for whatever their discipline.
thank you Clint
This is such a priceless tutorial! Thank you for making this available to the community!
thank you very much.
Amazing tutorial. Thank you! Something I always wanted to try. Keep the vids coming! 👍🏻👏🏻👏🏻
Thanks Jean. :-)
Excellent video! I appreciate this quick, and straight forward tutorial. Thanks Holocreators!
Thank you.
BEST 3D free tutorial as of the date of my post. How do I know? I've been searching this subject all Fking day lol. dozens of tutorials. When I take my work to the professional level. These are the guys, I'm going to call. Thank you so much for getting right to the good stuff. HAPPY TO SUBSCRIBE!
would love to see more videos like this!
thank you ;-) Did you see the STL to STEP video, its the sequal
czcams.com/video/5afn5N9fPdA/video.html
I’m actually amazed at the similarities of the 2 scans. The Photogrammetry would be enough for my project atm, I need to do a fair amount of modification / post processing anyways.
Thanks for the tutorial!
Happy you liked it
i am delighted to have stumbled accross your channel. I am a metrlogy professional having worked for a couple of OEM's as well as the original inventor of the CMM in my forty plus year career. I have found myself getting in to scanning and reverse engineering on a deep level this past year and am enjoying immensely this evolution of metrology technology. I appreciate greatly the clear, concise and helpful tutorials. A lot of people like to hide their expertise, making it look like some kind of secret, magic black art. Thank you once again, and having now subscribed I shall look at all the other videos that you have posted.
thank you very much Stephen
Well done mate, great video+explanation+presentation! Thank you for sharing - NEW SUB 🙏🏻
I am new to the realm of 3D printing technology, and I just want to thank you for providing such a comprehensive explanation. Your efforts have ensured that even someone with limited understanding, like myself, is able to comprehend the information effectively.

THANKS! With warm greetings from Siberia
Thank you Sunduck. Best wishes to Siberia.
Really great you taking your time to explain things, the item could be hung on fishing line and then do all photos in one hit.Quite keen to try this method.
Hi, the part is not allowed to move during the individual pictures you take. So in all pictures the parts has to remain in the exact same position. Otherwise the photogrammetry process will not work.
@@Holocreators You're obviously smarter than the average bear. So please forgive me if I sound pretentious.
I like David Butcher's idea. And it beg's the question...
Why should the part not be allowed to move? Would it be so that the object maintains some point of reference to where
it sits, in relation to the camera? If so... then wouldn't the surrounding objects (to which the main object is resting on) become
part of the main object? Yes. They would. But... why should the software require any additional connected parts? For a point
of reference? Hmmm. Interesting.
The real question is...
Taking pictures at different angles creates movement. If pictures are being snapped, by hand... the camera is then
...not stationary. What difference does it make whether it's the camera, or the object being moved? The object being
photographed is the ONLY true point of reference. The object's background, OR WHATEVER IT'S RESTING ON in any photo is
irrelevant, since it gets edited out anyway. So... why would anything extra, connected to the main object, be necessary?
Why would having your camera shot conform to an x/y axis, in relation the object's center, be necessary when either x or y is
not a constant? Because the ONLY REQUIRED points of reference are with the object. Anything else is irrelevant.
And, then again... I could be wrong. My apologies if I've missed something.
Thank you taking time & making the effort to post this. Much appreciated.
@@Seemsayin Hi, I am no scientist and I don't know how photogrammetry software really works. The way I understand it is that in a first step the position from where the photos were taken needs to be calculated. That is easier when the object remains stationary, because then the background can also be used for the camera position calculation. But photogrammetry software gets better and better and it could be that its now also possible to have the object aswell as the camera move. As long as the object itself doesn't change.
@@Holocreators Ya see? I knew there was something I was missing. Thanks for your reply.
Great video. Thank you!
Damn bro. I don't believe I watch this video until finish cause your explanation very interesting. woww
Thank you
Excellent thank you for taking the time to make this video
thanks mate.
Thank you for sharing this video!
happy to help
Damn this is awesome, now i can 3d print anything i want, i just had this idea of scanning something and converting it to stl 3d model from pics, didnt think this was actually this affordable.
Hi Martin, yes you can. The Scans can look rough sometimes and cutting away unwanted elements just in meshlab can be not enough. Then you should probably also open the scans in blender and do some more cleanup there. But then you can scale it and export and 3d print it. Have a wonderful day. Kind regards. Swann
EXCELLENT video my friend!
Thank you
BROOO thankyou so much, this really helped and the tutorial was really easy to use as well :)
Glad it helped!

Great video! Would be great to see also some tips and tricks on structured light scanning.
Thanks. Yes I am planning to do a structured light video soon. What kind of tips and tricks are you expecting on that topic? Then I can include that in the next video.
@@Holocreators how to setup with micro dlp projectors and mobile phone for structured light scanning
@@normanonyxdagang7440 That sounds like a fantastic idea. I will look into it. :-)
Great tutorial. As the company itsself sell scanned product eventhough they explain how to produce a free scanned product. That interest me a lot. Thanks for the video
Thank you.
Out of curiosity, at 4:40 when you're scaling your photogrammetry model, why did you calculate a scaling percentage instead of using the "target size" measurement to input your 76.2mm? It seems like that would give you better accuracy, as there's no rounding of the scaling factor. I mean, obviously the results speak for themselves when compared to the professional scan, but I found that step odd.
Hi Andrew, no particular reason, it's just one workflow that worked for me, if "target size" works better, then please use that
Great job!
Thank you! Cheers!
this is sehr cool. will try tomorrow. Cheers
Hope you enjoy
Great video. Thank you.

Very cool!
Thank you!
Very nice description.
How can I measure the volume of the subject if it’s a part of the body or face?
I’m very new to this, thank you.
Hi, when you transform the scan into a solid model, then you will be able to measure the volume. The model needs to be watertight for that. Many programs can do that, i think netfabb has also that functionality.
Viewer David Wilson found out that you "You MUST have a NVIDIA graphics card" to run Meshroom successfully. So if you don't have this kind of hardware you might want to look into Photogrammetry Software alternatives like Reality Capture.
Where is Meshroom saving the 3D files? This question has been asked by many of you. Answer: When clicking the "Start" Button for the first time, Meshroom will ask you where to save the Cashe folder: normally it goes to C:/Users/Computer-name/AppData/local/Temp/MeshroomCashe
In that location Meshroom will save all the project files. After the photogrammetry process is finished look for the "Meshing" folder, inside you will find the 3D model (OBJ)!
Where would you go onto printing after you made your 3D scan?
@@Pyotr_Troyan just send it to shapeways
very cool stuff
Thanks!
Great knowledge
thank you
Awesome tutorial! Loved the presentation style! I wonder if there`s any free or low budget combo i could arrange to improve precision and use this workflow you showcased for GD&T purposes.
Hi Ralph, sorry I don't know how to help you there.
That's awesome, great tutorial. Just off to go scan a 1/24 sports car!
Glad it helped!
I saw your video only today , congratulations , great work I would like to understand how photogrammetry works , I am sure that this video will be useful to me.
Thanks and welcome
Thanks very much for information (Australia)
Thank you Adrian, happy that it was helpful.
Excellent video. Great detail and thank you. Did this video remind anyone else of BCC? lol
Thank you.
great stuff indeed .... i plan to try using a programmable rotary table with a robot arm manipulating a DSLR
Sounds great, would love to see that setup. Feel free to send me some pictures when its ready: info@holocreators.com I want to do a video soon on a robotic arm with a scanner attached.
Gobez Hermi. Thanx
Thank you.
Taking all those photos looks a little tedious. Curious to see if it's possible to record a video instead, then convert the video to a bunch of images and use those instead. I'm impressed at how good the scan turned out 👍
Good point! But make sure its a high resolution video without camera shake or you will not get a good reconstruction. I have tried it.
well explained!
thank you :-)
great JOB .. THANKS A LOT
Hi, glad you like it. Have wonderful day.
Well done
Thank you very much!
This is great, hope it works for me
Thank you.
Awesome!
Thank you! Cheers!
6:24 I'd fine-align again after deleting the floor. One object has a floor, the other does not. This might confuse the aligner. Also, because these are 2 different objects, each might have an ever so slight scaling deviation from the other. I suspect this is where the 0.2mm error came from
Yes could be, these were also not perfect scans. But i think the viewer gets the point.
mind answering some questions for me? When we set a measure of an object in NetFab, does the program automatically set the other corresponding measures in their real dimensions? is it possible to improve the texture of the object for a possible 3D printing? thanks for this tutorial and greetings from Brazil.
hello, when you change the overall dimensions of the object in netfabb, the entire object will be upscaled or downscaled. So all measurements will be adjusted.
If you want to improve the mesh or texture you would need to use a software like blender.
A mesh modelling program like Zbrush would probably be a better option for cleaning up the mesh surfaces. Blender is more appropriate for solid modelling, whereas Zbrush is more like sculpting a piece of clay, allowing you to build up or cut down small sections at a time. It can smooth rough surfaces, fill divots, and so on.
thx for leaving out so many important details!
I suppose there are more detailed tutorials for all individual steps which I show here. If I would have shown even more detail, this would have been a 1 hour tutorial.
In reverse engineering discipline, it is not very important to be accurate on the surfaces.If there are not drawings(which is assumed,because if they are available, then you can just re-create the part, not need to scan it).And as far as the hole sizes and locations, you can check with caliper and readjust the scan, after you convert it into solid geometry on you CAD program(like SpaceClaim).....This, what you are showing here is very useful information for the industry. Can save a lot of money and time!
Thank you Jiri, I agree when there are no drawings and complicated surfaces then Reverse Engineering is a great technology
Would this method work for scanning a vehicle interior? I’d like to scan my doors, dash and trunk areas to allow for “to-scale” design work.
Hi, for such scanning I would recommend a handscanner. Something like this: czcams.com/video/sbCNUPyvgos/video.html
This took my, kinda high end 5 years ago, pc like 2 days to complete. Only just importing to mesh lab. Will update.
curious. but two days seems pretty long
Thanks for the great info.
2 questions
1) Can you suggest any similar workflow for a Model wearing a dress.
2) which software is used for the final slow motion rotation of product.
Awaiting reply
Thanks for all.
Hi, with a dress it can be much more difficult depending on the fabric, just give it a try. unfortunately I don't remember the software anymore i did the rotation with, almost 2 years ago ;-) but Freecad can do such turntable animations. you just let it turn and run a screen recording tool (OBS) at the same time.
@@Holocreators Thanks for Reply.

Very good video. Given you have only a Galaxy S6, but get quite amazing photos for indoor shooting, I wonder what the lighting looks like? Seems like proper studio lighting. Can you please tell us more?
Hello, for lighting I used two soft boxes. They make nice even lighting and you can get them on amazon.
This is an awesome video! But I have scanned a test model before and I didn't have to combine the top and bottom angles, it combined automatically in Meshroom. I think that's only the 2021/2022 update though. Great video!
Great tip! I didn't know Meshroom had this function. Yea the video is already a little dated.
Excellent video. It looks like picture-taking (200 pics in your case) is no doubt one of the longest processes in this project- would it be possible to use the Burst function on my iphone camera and use a slow sweeping motion (instead of incremental as you're demonstrating) to make the process a little faster? This should also allow taking of more pics for a better dataset. Of course, all of this is null if the pics are fuzzy. If one found themselves doing this on a repeated basis, a jig is in order- may be my next project :)
Hello and thank you. I think the burst function should also work. Just check the pictures afterwards so they are alle in focus and not blurry. Kind regards. Swann
Thanks Swann. Looks like someone had the same idea: czcams.com/video/m7ee4jLk_As/video.html
@@tallcypress I'd avoid the burst function. With photogrammetry you rely on the sharpness of the images. To get perfect results a tripod and shooting one photo at a time is what i recommend.
A turn table is often used to help with this. A steady tripod will also help to keep the distances similar. Then you can lock the focus on the camera so that things stay in focus. You'll probably find that taking pictures from further away helps things stay in focus better, especially with a good camera and a telephoto lens, since the differences of height on the details of the part will be small compared to the distance between the part and the camera, so it will remain in the depth of focus. If you have a decent DSLR camera, you can also use timed exposures or a simple remote to take pictures at regular intervals as you turn the part.
Thank you for the video! I cant wait to try it out. I'm having issues downloading the windows version. Any advice?
Hi Logan, no I don't know why there would be an issue with the windows version.
This is awesome! Can you 3D scan an object and invert it? Meaning can I scan a left object to make right object?
yes you can mirror the 3d object
Excellent
thanks!
Would a small welder's turntable, a tripod, some lights and an object of known size at known distance make this even better?
Yes you could get a better result that way. But make sure to have an even background then. Like a grey screen. Otherwise the photogrammetry software (meshroom) will be confused because the object in front is turning but not the details in the background!
@@Holocreators thanks for the reply, i'm off to the store to buy some of the greenest fabric available...
I have some experience in studio photography and fabrication, trying to get into 3d modeling and printing on my own. This would help a lot.
@@mindbreak666 It doesn't have to be green. Dark grey is good too.
Thank you
happy to help :-)
So a lot of diffused lighting would be good for this.
Yes you need a lot of diffused light for the best possible scan. Light is your friend.
