How to Scan 3D objects with Agisoft Metashape: Basic Photogrammetry

[@elhfay4563]

Nice job, I do 3D scanning all day with structured light for inspection and I'm just picking up photogrammetry as a hobby so I bring my skills to photogrammetry. So a quick tip, if you need to ever coat something but spray paint is out of the question get an airbrush kit, 99% IPA (rubbing alcohol) , .05ym pure aluminum oxcide(raw make base can work just clogs the brush), mix 1/4tsp aluminum oxcide, .75oz IPA and mix well (it saturates better in largers batches) spray evenly about 8" away, don't spray in 1 spot... It goes on lightly but when it dries it's coated (it dries in milliseconds...but the best is it washes right off/wipes and the part isn't harmed

[@EricStrebel]

Good tip

im a 3rd year ID student @carleton your work is the most informative stuff on youtube. Please keep it up i tell all my mates about your channel. thanks for helping us learn the right techniques. We never get these focused lessons for tricks across the trade.

[@paul.hesketh]

Eric, I would love to see a vid outlining how you interact with the data: what you do with the mesh, .obj file etc. How you would bring it into CAD and make a solid model from it with a thickness. That sort of thing.

[@irgendna]

Great, what i like abt this tutorial is that its quick and self explanatory. thanks!

[@Made2hack]

That is incredibly powerful for just photos taken with a camera, as opposed to having to use something like a laser scanner. Thanks !

Good tut. Meshroom is a free software package that also does photogrammetry. Might be a bit less consumer friendly and has less editing options once you have the model - its more of a wrapper around a computer vision framework. (So you do get a whole bunch of options in terms of the CV functions) Are there not any available 'texture' spray paints that can do the noise pattern in one go ?

[@DanielCGCG]

I've had some good success with meshroom. It takes a bit of getting used to but great results

[@EricStrebel]

Thus I am using Metashape, works on a Mac

[@erezgonene1]

Aperture should be high value (close Aperture) NOT low, all of the object should be in focus and even if the background is in focus it is better, because it will make it easier for Metashape to align the photos based on that info. After the photos are aligned and a point cloud is generated, it is very easy to get rid of all of the background.

[@TheoWerewolf]

Should be noted, Metashape is available for MacOS, Windows and Linux. Windows 10 actually comes with a pretty good set of 3D editors, painters and printer software built in and integrated with Windows Mixed Reality (if you have a compatible VR headset)

[@jolyanesaule3262]

Hi Eric, thank you for this video. It's very informative and clear. I'm starting with photogrammetry and I need to create a 3D version of an object with a scale. Should I take pictures of my object with a physical scale or can I put one with the software?

[@EricStrebel]

Measure your object and then just scale it in CAD later to the exact size the object should be.

Thank you for this useful video

[@mikescncshop]

I have black and somewhat shinny objects I would like to scan but can't use any type of permanent paint on them. It there anything that would give me the flat textured appearance of paint but could be washed off afterwards? My original thought was to use some type of shrink wrap so I could paint it then remove it when I was done. Haven't found anything that will shrink tightly to the shapes I am working with.

[@DenisGerbassi]

Thanks for sharing. Best tutorial on youtube about photogrammetry.

[@EricStrebel]

Thank you!!!! I might make another one possibly. I have an idea I want to try. Don't forget to check out my Kickstarter campaign for the "Alfred" Backpack hanger kck.st/2Yi2Qnd thanks for your comment and support much appreciated.

[@wwkdiecastmore5647]

A great design!

[@SianaGearz]

I heard of hair spray and hair highlight spray being used to prepare the object for photogrammetry and scanning without modifying the object permanently. The hair products will just wash off with warm soapy water. In my little experience, hair spray needs to be sprayed on from a distance of over 1ft and at an angle, then it falls down in microscopic clumps and makes for a very dull matte finish.

[@EricStrebel]

Good tip, thanks for sharing. Much appreciated :-)

Can you save / export a STL out with Metashape?

[@mikebreler9724]

Does this program run on Mac OS Sierra or Mojave, or is it only for Windows? Thanks

[@EricStrebel]

Head to the developer web site for all the details

[@georgeaura]

How many pictures would you say you need in general?

[@EricStrebel]

It will depend on the object but I would say 50 to 100 would be a minimum to get something decent

[@davidvalens3337]

do you still use this method in 2020 or have you purchased a 3d scanner?

[@gilbertovertiz6699]

Hi did u it’s possible to scan the bed sea with only my ROV and that software?

Hi Eric, thanks for your tutorial. I have a trouble, when I import my model into cinema 4D, it just shows me a white model rather than that I scan one with color. What wrong with that? And What should I do? Thanks in advance:)

I need 3D model of furniture objects for my final year project. Can we apply this to a furniture objects i.e Chair, table etc.? Thanks.

[@EricStrebel]

Yes, I don't see why not

[@vincefrommenton]

Raheel Rajput I think for a better resolution during the shooting you can use un aromatic turning plate and shooting during the rotation

[@rajaraheel7590]

Please explain some more

[@vincefrommenton]

Raheel Rajput for a real good scan it’s better to use a turntable with little engine for rotate and you shoot on 160/180 degrees and let turn the table. This technic help the software to assembling picture. The light is important to for some better result you can check Pano2VR soft if you want it’s another alternative

Hi great explaination, but I have a problem: it always says this message: "SOME PHOTOS FAILED TO ALIGN. PLEASE RESET ALIGNMENT FOR INCORRCTLY ALIGNED PHOTOS AND RERUN PHOTO ALIGNMENT". I tried even with only two photos but same message. Can you help me?

[@EricStrebel]

No idea, I would reach out to tech support, they are responsive. Tell them u saw the vid!

[@egbainbridge]

I started photogrammetry about two months ago - by watching this excellent video - and in my experience, this error message has always happened because I accidentally changed my camera's zoom, causing photos to have different focal lengths. I'm sure there are other causes, but for me, being careful to make sure my focal length is the same on all my shots solved the problem (I've taken close to a thousand shots so far on my project).

[@EricStrebel]

Thanks for the tip!

[@egbainbridge]

Since posting my previous reply, I've learned another cause of the problem, at least with Metashape. It's because the photos being aligned somehow don't give the software enough information to know how to fit them together. The solution I've found is to group photos into chunks, and then align the chunks. In my case, I had 1200 photos of a large archeological object (about 40'x40'x15'). A lot of them didn't align even though their focal lengths were all the same, so I divided the photos into groups and created a chunk (using the Add Chunk command) for each group. If some photos in one chunk didn't align, I removed them from that chunk and aligned the rest in the chunk. Then I'd create a new chunk for the photos that didn't align. When I had all my photos divided into chunks in which the photos all aligned (I had five chunks), I used the Align Chunks command. In my limited experience so far, as long as the photos within each chunk align and there's enough information in the photos for the software to know how the entire object fits together, the chunks will align and you'll have a single model.

[@EricStrebel]

Wow, that's cool, I did not know that about the chunks, thanks for sharing, much appreciated

[@stephenstrebel8165]

Good stuff..

[@FyL43]

How does he know where the photos are taken ? (sorry for my english) with gps/glonass ?

Hi Eric, thank you for your video, but when I open my .obj file on Autodesk fusion 3d the color are missing, how can I do to solve this ? Thanks

[@EricStrebel]

The texture map is not supported in Fusion

[@error079]

Can a turntable be used?

[@EricStrebel]

Possibly, I have not tried that.

[@lukefrahn8538]

These systems seem to rely on mapping the environment and the environmental light on the object. So no; you need to move the camera, not the object.

[@error079]

Put some tracking markers on the turntable

[@lukefrahn8538]

@@error079 Buy the largest 'lazy suzan' bearing you can find and make a donut shaped turntable. Mount a camera on a boom to it, with a counter weight on the other side. Place the stationary object in the middle, point the camera inwards, rotate and shoot. Let us know how it goes!

[@Atoufidou]

It s possible but you will need to generate alpha mask for each photo (autogenerate with photoscan xD) and have a perfect lighting setup. You can also scan top and bottom of the object and merge chuck with photoscan to have the whole model.

[@Proutprutproutprout]

Interesting..

[@halosrusty]

I have a couple items I really want to photo-scan as I’m no 3D modeller, however the product is white and shiney. Any tips

[@EricStrebel]

The object needs to be as matte and flat as possible with some reference point textures on the model follow the tutorials and you should get some decent results

[@charlesdib1111]

Hi i am trying to follow your tutorial but when I try to import the images it says it can't load them. Please help

[@Pfffffffffffff]

Good tutorial but the resulting model is a messy mesh of polygons with bad topology and would not be good for remodelling or editing. I am still to find a good tutorial on how to reduce polycount/remesh scanned objects so they're not a mess.

[@EricStrebel]

Let the software maker know, perhaps they could implement a way to clean it up, try mesh mixer.

[@christiandiblasi5333]

👏👏

[@AustinBeaulier]

Why not use a turntable?

[@EricStrebel]

It's not clear that this is possible without some trial and error, perhaps it could work but the lighting will need to be very very even. More time than I have at the moment, it would however be an ideal set up.

[@Mottersmotters]

Hello nice video thanks. I use auto desk recap photo or mesh room. 👍 Both free as I am a tight bastard lol

[@GiorgioAresu]

"I need to scan a bottle to figure out its volume". Yeah, I guess it's easier than just measure how much water does it take to fill it.. 🤔

[@EricStrebel]

Cool, good luck with the project, although feeling it with water is going to be way faster

[@vulrath8154]

I think he was poking fun at you .. :( However, I care not why you scan the bottle, and very much appreciate the video. I want to use this method to make copies of miniatures to create a 3d printable version of them. (I want to print in translucent PLA to make "invisible" versions) will this capture detail on objects that are between 1.5 inches-3 inches?

[@GiorgioAresu]

@@vulrath8154 Correct :D I really appreciated the video, it was not intended as a negative comment, I just laughed when he said it :) BTW I just made a single attempt at photogrammetry, so take this as a not-so-informed advice, but I think it all depends on whether you're able to succesfully focus the subjects at such a close distance. You always want to fill the frame with the subject, so distant photos just aren't gonna cut it...

[@vulrath8154]

That is helpful, I plan to make attempts this weekend. I think im going to make a platform that I can mount my camera too that will allow stability, but up close with a rotation feature. Been trying to do this with free apps....just doesn't work. This gives me hope!
