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

[@Holocreators]

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)!

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

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

[@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]

As my siblings, and I, disposed of the belongings from my parents last house ... I was able to grab an antique (probably early 1900’s) globular, store display, dispensing jar made of glass. Our family over the generations have used this as a cookie jar. As I was cleaning it, it soon became clear that the cover that now exists was not the cover it originally had. To my best guess the original cover may have been glass, or possibly even a shaped steel sheet. The top of the jar has threads that suggest that it may have gently screwed on. Yes the worst case scenario is to strip the aluminum cover of its paint and repaint it to match the base of jar (presuming it came with the original jar) but then the threads of the actual jar would still be ignored. Questions: Would it be possible to get this jar scanned to both get: • The essence of these threads for reproduction of a new lid? • Would it also be possible to get a scan to capture the glass design with the thought to handing the scan to a glass craftsmen to reproduce a likeness it in a new cover? I am a person with multiple disabilities. The skills needed to produce a new cover for this antique are beyond my skill set. In the past I have tried to contact Minneapolis/St. Paul, Bloomington Minnesota area maker studios and all I have gotten is dead silence. Is there a ‘correct’ way to contact a Maker Studio to connect with a maker who might have the time to work with me on this project? OR is there a company in my area that help with this project?

[@Holocreators]

hello, scanning the threads of the jar is possible with this technique. But you have to take very high resolution images. The scan will then only be a starting point to analyze the thread pitch. this will need to be reconstructed inside a cad software to create a new lid. this new lid can then be 3d printed. I could do all of this for you, the price would be probably around 300-400 EUR. For a more accurate estimate please send me a picture of the jar and needed lid to [e-mail]

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

[@woodwaker1]

Something that I think should be mentioned at the beginning is the requirements for hardware. You MUST have a NVIDIA graphics card. I have an I-5 and use internal graphics. After going through all of the steps and starting the conversion I finally figured out that It error ed out in step 7. I can understand that they built the software to use a specific hardware minimum, but many of us do not have it and I don't like wasting a couple of hours to find this out.

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

[@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.

[@tallcypress]

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 :)

[@Holocreators]

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

[@tallcypress]

Thanks Swann. Looks like someone had the same idea: kzbin.info/www/bejne/o2jIlmeggdCSd9U

[@Shoopadawhoopa]

@@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.

[@reverse_engineered]

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.

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.

[@Holocreators]

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.

[@cedricpod]

great stuff indeed .... i plan to try using a programmable rotary table with a robot arm manipulating a DSLR

[@Holocreators]

Sounds great, would love to see that setup. Feel free to send me some pictures when its ready: [e-mail] I want to do a video soon on a robotic arm with a scanner attached.

[@elizabethoommen4115]

Thank u for duch detailing.👌

[@Holocreators]

happy if it was helpful

[@DCDLaserCNC]

Excellent tutorial/info! Thank you for sharing.

[@Holocreators]

thank you :-)

[@nickm2724]

Thanks for the video,very helpful.can you take pics from more than 2 viewpoints and combine via the software ?,thanks again

[@Holocreators]

hi, no you will need at least 60 photos I would recommend, even better 100-200. Two pictures is not enough.

[@nickm2724]

@@Holocreators Hi,thanks for replying,I didn't explain myself properly.I meant from more than two planes ie the first set of 60+ photos at an angle of say 15 degs from the Horizontal the next set of 60+ photos from 30 degs from the horizontal the next set from 45 degs etc. Hopefully that's a bit clearer ? Thanks

[@Holocreators]

@@nickm2724 yes thats a good idea to make the photos from different "planes", I don't know if you can see it in this video but I used about 4 different planes.

[@rodrigomartinsfarias8689]

great work! Whats the method's accuracy?

[@Holocreators]

its really accurate. I would say down to 1mm, which is great for photogrammetry.

[@GlueChickeN10]

Bravo! That's how to sell your service. Teach me and learn me at the same time.

[@Holocreators]

Thank you

[@CascadianBraeden]

What I'd like to know is how to do accurate room-scale 3D scanning (scanning the interior of a room or series of rooms) without having to spend thousands on a specialized device like Leica or Matterport. I got an occipital structure sensor for a few hundred, but the quality I'm lookin for just isn't there. The deviation error can be up to a full inch off, and the iPad memory limits you to about 15 seconds of scanning time before maxing out.

[@Holocreators]

Photogrammetry is not so well suited for room scanning. It can be done, with many individual scans stitched together but its a lot of work. I would highly advise to rent a laser scanner for this task. In Germany you can rent a Faro Focus 70 for 200EUR for one day. Thats enough time to scan an entire house from the inside and the data quality is superb.

[@luisfilipelopes2900]

Well scanning rooms is very difficult, specially in a precise way, since you have to be at multiple distances from the object, and there is little to reference it (like plane wall with no detail). If you try adding markers that appear in multiple images, it will be easier for the software to produce a good model. Markers can be anything from precise dots (white inside, black around) which are perfect, to crosses you can draw on walls, to furtiture (that actually helps as it has form and colours a scanner can corellate). Of course this means setup, and time consuming. This is why you pay money for good scanners that are professionally used, because they accelerate your work and bring you money back. Also by being more precise, you spend less time correcting errors and have a professional work to deliver to your client, or if it's you that are working withe the files, you work with confidence and fast

[@Holocreators]

@@luisfilipelopes2900 I absolutely agree with Luis

[@iheartmysquid]

Couldn't you add a reference object to the scan? like a gaugeblock sitting right beside it.

[@Holocreators]

Yes you can. Great idea. I'll do it next time.

[@Casey-tm6tv]

@@Holocreators something i saw online on someone's setup is that they lined the base of the box with newspaper

[@Holocreators]

@@Casey-tm6tv Thank you, this could help with the registration of the images. also you should always place a ruler in the scan to make scaling easier later on

[@jayinmi3706]

Excellent video. Great detail and thank you. Did this video remind anyone else of BCC? lol

[@Holocreators]

Thank you.

[@imnotok1989]

Can you recommend another method of scaling now that Autodesk killed Netfabb basic?

[@Holocreators]

Hi, is the old version not working any more? github.com/3DprintFIT/netfabb-basic-download/releases

[@UnicornRiderNarresh]

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.

[@Holocreators]

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.

[@UnicornRiderNarresh]

@@Holocreators Thanks for Reply.

[@ammaralkareem490]

Hello there .. thanks for the video it's really good, I would like to asking about the cheapest house scanner... and thank you again

[@Holocreators]

well you could use this technique to also scan a house, otherwise I would recommend laser scanners to scan houses, for example the faro focus

[@luminousfractal420]

So long as my models stay on my computer and aren't collected. 3d models are kinda valuable these days. Also wondering if you could use video frames. Say you take a video and pull every 100th frame and use that as a picture. And would like to see how it compares to Googles augmented reality scanner which a lot of phones are capable of using now.

[@Holocreators]

Yes you can also do photogrammetry from video frames. But I would recommend taking still photos. Much better quality.

[@hallenw]

Have you tried Lidar on newer iPhones or iPads?

[@Holocreators]

yes LIDAR works great, especially for larger parts. This tutorial will work with photos only.

[@imansalam01]

hence on here a month later. thanks for making feel normal again.

[@Holocreators]

Welcome back!

[@mikecoughlin4128]

Would the phone scan be better with the latest multi lens phones? What is the driver, picture resolution?

[@Holocreators]

newer phones have better cameras so yea the quality will improve, for best quality always use dslr cameras

[@nelsondog100]

Very cool! Can it be done using a Mac?

[@Holocreators]

Unfortunately not. Maybe with a different photogrammetry software like reality capture

[@starhawke380]

I have a plastic part for a car I need replaced. It is no longer available new or used. It is the cover for the electric power seat controls. 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]

[@186scott]

I wish I had found this video when trying to recreate parts for my car that you can't buy as it too me fore ever to try and make the parts by measurements

[@Holocreators]

Yes this can be used for car parts. You have to be really accurate with the reference measurements though.
