3D Scanning for Free

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):
alicevision.org/#meshroom
Meshlab (for the 3D Scan Clean up and to combine several single scans):
www.meshlab.net/#download

Hello. Can you tell me, how I can scan something bigger. How I can scan a car? Thanks

[@Joe_Not_A_Fed]

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.

[@Holocreators]

Thanks Joe for the kind words.

[@mgpmbass3616]

Agreed! It's nice to have a detailed tutorial that isn't ruined by loud background music.

[@delsings]

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

[@galaxya40s95]

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.

[@QuantumKatmusic]

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.

[@officiallyanthony]

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

[@____________________________.x]

[@davidbutcher6637]

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.

[@Holocreators]

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.

[@Seemsayin]

​@@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.

[@Holocreators]

@@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.

[@Seemsayin]

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.

[@Holocreators]

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

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)!

[@abrannan]

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.

[@Holocreators]

Hi Andrew, no particular reason, it's just one workflow that worked for me, if "target size" works better, then please use that

sure it can be done. that shouldnt be a problem. thats the beauty about photogrammetry, the size of the part doesn't really matter as long as your able to photograph it from all angles. Be sure to place a measuring stick in your scan though.

[@marcusmikkelsen7668]

Would using data from acceletometer and gyroscope from the phone while scanning improve the quality?

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

I have one in good condition, I need the one for the other side which is a mirror of the one I have. Can the one I have be scanned, then mirrored and then 3d printed? If so, who can do it for me as I have no intention of getting a 3D printer and being on the ATF watchlist...

[@Holocreators]

You can't get a 3d printer when being on an ATF watchlist? Thats wild. But to answer your question. We can 3d scan your car part, mirror it and send you the files or 3d print it for your. Please send me an email to [e-mail]

[@jiritichy6855]

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!

[@Holocreators]

Thank you Jiri, I agree when there are no drawings and complicated surfaces then Reverse Engineering is a great technology

[@wesaderty]

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.

[@Holocreators]

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.

[@reverse_engineered]

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.

[@torbens.jensen7670]

Could you make a bigger yellow plate or "Studio-green" - and remove that in photoshop, and then dont need to 3d-scratch that off later on, so you only have the core object ?

[@Holocreators]

Hi Torben, yes that is be possible. You would need to post process (mask) the pictures then.

[@matasmate]

I've tried this method, but for me it wasnt very successfull. I have gotten an old car plastic part which i wanted to scan with meshroom, it did, but because of the part is black, the images doesnt give back the true geometry when its processed by meshroom, i tried painting it yellow or something brighter, but that only solved some of the problem. Do you have any recommendations how could i improve my scanning or the results?(after the meshroom process some part of the plastic is missing, i dont know why).

[@____________________________.x]

Paint contrasting dots all over it and rescan. It works for Hollywood

[@Holocreators]

I agree with the horse ;-) . Paint it bright white and add tracking markers. Also the object needs to be well lit so the scanning works well. Use diffuse lighting like in my video please.

It is really good tutorial. But, what about another program like meshroom >> meshmixer or blender or samething else where it is possible? I keep getting error in DepthMap (camera not reconstructed) also with nvidia cuda toolkit installed. So is there any possible free or open source? Or even if its possible with smartphone getting model with scanning app that would be awesome too.

Hi, sure there are other options, like for example reality capture for creating models from photos

[@lonerangerfilms4007]

Is their any software like meshroom compatible with Mac OS

[@Holocreators]

you could try visual fsm, though its not so easy to work with. Generally all photogrammetry software seems to be optimized for windows, I have no Idea why.

[@TheShooter466]

really struggling with meshroom, working through a lot of errors with absolutely no clue what i'm doing

[@Holocreators]

please check youtube, there are many more up to date tutorials on every aspect of the software

[@VirtuelleWeltenMitKhan]

very cool stuff

[@Holocreators]

Thanks!

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!

[@Holocreators]

Great tip! I didn't know Meshroom had this function. Yea the video is already a little dated.

Can these be transfered to sketch up. I do stereos and would like to be able to scan trunks so I can build boxes to fit tighter

[@Holocreators]

when you install an extra plugin for sketchfab you should be able to import obj files into it. obj is the file format in which meshroom exports the files

[@elmauto3021]

@@Holocreators thanks for the response, now I have to try it
