Hi, Eric. I am also Eric. Thank you for this great video. I am exploring photogrammetry for 3d modeling and printing. Just one question though... Have you ever seen a picture of someone getting their hair caught in a piece of machinery? It is not pretty and depending on the machine it can be fatal. Please have your helpers adopt basic shop safety if you are going to include them in YT videos. It is the responsible community member thing to do. Ok, lecture over. Thanks!

[@EricStrebel]

Thanks! I appreciate your concern.

[@catchmeifucan6814]

there is something you didn't explain or got me confused about, u placed a panel behind the object and that's not good, the 3D software won't be able to understand the location of the camera, yet you got perfect camera coordinations , but in order for that to work you need a background like the first clip, if the background is different in every shot, the software works out the location of the camera, so I am really confused, I had to experiment a lot to come to this conclusion, how did u work this out ?!?!?

If you rotate the object the lighting will change from shot to shot confusing the software.

[@izoyt]

photogrammetry doesn't work in that way, you need to orbit object with your camera, no just rotating object in front of it. anyhow, very nice idea, i would add also some lighting etc. congrats.

[@veropag1850]

thank you for building this, it proves what i thought and i'll have to make myself a rig like that for doing 3d scans

[@cedricpod]

so my spin of your wonderful ideas is the following ........ DSLR camera that is remotely triggered. Camera is attached to a fixed robot arm that moves to appropriate angles . Object rotates on turntable controlled by stepper motor. Diffused LED lighting rotates with the object. System is shielded from stray light ( darkroom ? )

[@EricStrebel]

I like your spin, but who's going to design and build all that extra stuff it's just not worth it for me for occasional use.

[@cedricpod]

Eric Strebel .......i can definitely see your point

[@rodrigojager]

What if you add a chessboard background instead of a white one, so the machine can compare it and make some calculations? Does the software allows you to manually or through script, telling what is the position/angle of the picture? So if you are using a stepmotor, you can tell the software exactly how many degrees you turn in each picture. What about placing some line lasers and taking the pictures in a isometric view, so you can calculate the distance from the red curvy line projected on the surface to the turning axis (like in a solid of revolution, where you have the line of each degree that will spin).?

[@EricStrebel]

Rodrigo Jäger I have no idea, reach out to the software manufacturer, as far as I can tell it figures all that out by itself, watch my most recent scanning video here for more insight. kzbin.info/www/bejne/mGLXZGaBmKefpM0

[@rodrigojager]

As far as I am aware, it uses artificial intelligence comparing features from the 3D object and from the background to process how one picture connects to the other. That is why I believe having some sort of background, but still easy to differentiate from the object itself would help. Your result is amazing already, I was just wondering if you can combine this technology with others like counting known steps or tracing projected laser lines to pixels in some sort of triangulation and high order linear regression would improve the results for more situations. We know for instance that if the reflection of the light is not perfect due to refractions in materials like glasses or reflections in shinning objects, it would not be that good. So maybe it is possible to improve it with low cost technology and getting a quality better than some high cost solutions...

[@snowwolvesproductions]

wouldn't it have been easier to just rotate the bottle instead. you could even have used a motor to turn it slowly. The light would stay constant and so would the background...?

[@EricStrebel]

sure would, but this software does not make that easy.

[@steffiheaven8738]

Hey its a pretty cool project and I liked the way how you did it. I was wondeing if you have any problems scanning Objects which have a uneven bottom. Because your camera is only in one spot. I was thinking if you move the kamera from the top to the middle and then to the bottom, then you might get a better outcome. What do you think of that?

[@EricStrebel]

camera moves, three times actually, yes, you will have a problem on the bottom, you need to figure that out depending on the object and your priorities for your project.

[@Konradulations]

what would be the difference if I rotate the object instead of the camera?

[@EricStrebel]

Probably will not work with this software

[@Konradulations]

@@EricStrebel ok thanks for the reply. Did you try your setup but witout the background? If so it would be interesting if the result is better but i guess if you build this kind of kamera rig attaching a plain baclground to the other side is the least amount of work...

[@RichSobocinski]

Why wouldn't you just rotate the object in the center and keep the camera, background, and lighting stationary?

Rich Sobocinski most os the software does not work that way, unfortunately. It wants the camera to move and the object and lighting to remain constant. Thanks for your comment.

Scott Tuttle good question! You are definitly right about the bounced light. I would think that there needs to be enough contrast between the object and the background and then that could work. Dunno, might have to try some day. Thanks for the suggestion.

[@EricStrebel]

Rich Sobocinski Don't worry you are not alone, lots of head scratching going on with this photogrammetry software and process. But the other way just does not work so great when the object moves unless the lighting is super constant. The software seems to play a big part in the equation as well, basically I am tricking or hacking the software on a physical level.

I actually made something similar to this for curing resin prints. I took a lazy Susan and put a circle of wood on it. Then I attached a synchronous motor out of a microwave to it to rotate slowly. Works pretty good for photogrammetry too

@@MrMikedejeuner I'm not sure how you built your system, but I'm a software dev and I was doing an iPhone scan before Lidar and it was an older phone. It needed feedback for all the things it got and took a while to get the details. One of the key things is that it has to be able to know what side it's currently doing, in order to put things in order. Kinda like a single die, you have sides that are all different because they have a different number of dots on them. I've never built my own scanning system, but I'd guess it would need to be a slow turn and hitting different angles would probably help too. I think it's the background that matters. Maybe the phone knows more about where it is when you move it.

Nice work. I had my design idea since two years. The arc which is carrying the camera is near quarter of a circle which goes from -15 degree to 80. But instead the rig is rotating around the subject . The subject sets over a turn table and turns around its axis which is much easier . And the subjects sets inside a lighting box which diffuses the light. Which is necessary for quality photogrammetry.k

WOW I'm a newbie to this photogrammetry and having racking my brain on why my image of a white plastic 1/16 scale car body does not reproduce. I think I need to build me one of these tables verses trying to walk around it. What a great experiment that you did in making this. Thanks for the time and effort. Look forward to seeing more of your videos and will have to subscribe.

Why make the camera rotate around the object?.. Why not just make the object rotate?

[@EricStrebel]

Because that is how this software works

[@user-ml3nf2xn6o]

@@EricStrebel I want to know which program you used

[@mrbob92679]

One other question. How did you determine the camera length?

[@KirstyTube]

Wow that's quite impressive! I'm working on an auto shoot that rotates the object with a stationary camera but I doubt I will get results anywhere this good :/

[@cdentista10]

very good !

Greetings Eric. So glad I found this video and the way of using lazy Susan. I do have some questions though, and if it's possible some kind of modifications to this model. The issue with my model is that, well, it's a full size mannequin with old ethnological outfit. I need to create a small printed 3D model from the mannequin, something like palm-sized model, using of course the method of photogrammetry. I was thinking of placing my DSLR on a tripod and use additional studio lights which are controlled by a trigger from the DSLR. Then, placing the mannequin over a lazy Susan base (made from something more sturdy than a plywood, probably steel lazy Susan), and using the same technique like you - rotating every 10 degrees for a full circle. The background is going to be white canvas (used for photoshoots of real models) made as infinity wall (without a corner behind the mannequin) My dilemma - is this way of rotating is efficient and reliable? I'm going to use the same light and photo settings, and there aren't any glossy or transparent surfaces. Thank you.

Yes, the subject on a lazy susan will work too. Make sure to take 36 shots each from ~10’ high, mid height and low height, trying not to change the distance from the subject.

What I found to work best for me is to rotate the object itself, the final texture comes out uniformly lit on the entire surface, this way the object can be accurately lit in the 3d engine. Just a simple turntable used by cake shops, and the camera set on a tripod at different heights

[@EricStrebel]

What software supports that? Most do not....

[@thomaserikssen4792]

@Song Zee: Your result is impressive. Did you motorize the turntable, or manually spin it in increments? Any photos or footage of how your process goes? Also, I'm curious why you mentioned you had to do different heights with the camera+tripod...

[@DenisVFX2]

I have the same idea, why rotate camera, it’s easier to rotate object itself. If the lighting is ambient and close to constant the result should be fine…

[@EricStrebel]

The software does not work that way

[@sachacarnelos]

nice

[@MehmetKozal]

Great one man.

[@AustinBeaulier]

Best to move the turntable and not the camera. This contraption looks unwieldy. Also a waste of time and money because I can get a better quality faster with just a turntable and a tripod.

[@EricStrebel]

Thats just how this software works my friend, I wish it were easily possible with the way you describe but the light has to be super diffused for your idea to work with this software. Thanks for the comment and support!

[@admiralevan]

Love it man, great stuff

[@EricStrebel]

Thanks!

Which softwere use after scanning to mesh

[@coulterjb22]

Eric, did you use the standard version of the software or the professional? And did you check to see how well it captured the true size of the object it scanned (the standard version you have to manually play with scaling to get it close).

[@EricStrebel]

I have a licensed copy of the software, scale is not relevant for me, have no idea what scale it is is once it's done, I just scale it to what I need.

[@julianruan1093]

Yooo what programs did you use ???
