What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Iconasys automatically removes the background on each image too.

@ahmadaisabry 4 года назад

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

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

@MrMikedejeuner 3 года назад

somehow it didnt work for me, the camera really has to ''move'' around the object to translate it in 3d correctly I guess

@karljay7473 3 года назад

@@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.

@gordoncouger9648 2 года назад

Given a choice I always turned the subject rather than circle it with the camera. I think it is easier to maintain uniform lighting and a great deal faster as there is less time between images.

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 .

@steffiheaven8738 4 года назад

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.

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.

@dbldzo 4 года назад

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.

@califuturist 3 года назад

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.

@mrbob92679 3 года назад

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

@Ciupremo 4 года назад

Idea was good! But maybe it was easier to put a rotating table and fix the camera so the object is just there, at the same height within 0.5 mm difference. With that long arm holding the camera, there's a momentum that moves a little up and a little down the camera. Another tip, you could use a remote app to shoot photos avoiding any micro-movements. And... last but not least, adding a flat egg timer under the table, could automate the rotation so the only action would be press the "Shoot" button on the smartphone :))) Btw nice video!

@rodrigojager 4 года назад

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 4 года назад

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b1t33KcBlnk.html

@rodrigojager 4 года назад

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...

@EricStrebel 3 года назад

Dunno

@AhmadShahwaiz 3 года назад

Because white would reflect light and it can cause issue

@pjanoo6973 4 года назад

Is lighting that important? would it be helpful to have top lighting to simulate mid day to avoid shadows

@EricStrebel 4 года назад

Yes apparently light is important in photography and it needs to be has diffused as possible with the setup.

Hi Eric, thanks for project..but i m confused of stationary turntable and rotating the camera? What is the difference ? Why we didnt rotate the object instead of camera?what is the point? Thanks again

@EricStrebel 4 года назад

This software works better this way

What can save a lot of time and can take up to 11,000 pictures per rotation is a computer-controlled photography turntable. Iconasys makes 6 different sized turntables (1.5lbs-500lbs.). Set however many images and angles you want. Automatically removes the background on each image too. www.iconasys.com

@catchmeifucan6814 3 года назад

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 ?!?!?

@Rufus066 4 года назад

Add a random pattern to your rotating base for better detail and tracking

@Eric Strebel Great video. Very informative. Thanks you for sharing it. Do you think the camera could be mounted onto the Lazy Susan and pointed outwards so as to take photos of a small room? I'm wondering if Photogrammetry could be used instead of Lidar scanning?

@EricStrebel 4 года назад

Possibly, try it out see if it works

@abhinavsivakumar6403 4 года назад

Would rotating the object instead of the camera work if my lighting is diffuse and I put distinguishing marks on the rotating base?

@EricStrebel 4 года назад

Try and see if it works, possibly it might

@euclidallglorytotheloglady5500 4 года назад

At first I thought it might be possible, but I don't think so. Say you used the same object Eric did, I think in your version the end result would be a model that was cylindrical with the features of widest edges.

Insted of moving the camra around the object make the object move instead. Great show

@TheRealFOSFOR 4 года назад

You shouldn't change the lighting on the object. By moving the object, all the shadows will be different in each shot. The photogrammetry program will freak out when it can't recognize where to put the different looking images.

@califuturist 3 года назад

@@TheRealFOSFOR How about eliminating shadows by putting lights at the stationary camera?

@TheRealFOSFOR 3 года назад

@@califuturist It will still create shadows in different places in each shot. Plus, normal shadows helps the program recognize the different pictures and angles.
