It's Time To Put Open Source Photogrammetry In Your Toolbox

Excellent video! What RC truck is that?

Using FOSS: Yay!

And an Nvidia card.......... Oh.... Us FOSS users own ATI graphics cards since Nvidia refused to participate in FOSS for so long. Pity, was very interested in this video.

Bro came back after 9years and just posted a super useful video. Very appreciated, thank you😁

scan with iphone 11 is better

but meshlab sucks soooo bad, sooooooo bad....

11/10 explaination !

Great video, slick system, very informative, Thank You!!!

Sadly the Cuda requirement is a dealbreaker :( Also, from an open source standpoint a solution for AMD cards would be lovely

i used to do this for fun a long time ago using "123d catch" and later "3DF Zephyr" 😅

Awesome! Instant sub. ❤️

Thanks for your time and trouble making this, much appreciated!

We can't use Radeon Graphic?

I'm still waiting for a good OCR AI that can read old math books and transcribe all the formulas without any issues

> Open Source Photogrammetry
> Uses an nvidia only tool on windows.

Yeah, right...

why not just scan with an iphone with the lidar. does all the computing on the phone in the app and puts in scale and even color pretty accurately.

Seems way too much of a hassle compared to taking couple pictures from different axis and scaling picture to sketchplane and using that and simple measuring of target.

Try nerf it even work on reflective surface as well

How would you change this workflow to make a 3D model of something big like a house or garden?

Fascinating!

Blender can take a video and turn it into individual images in a folder, FYI.

Wow, this process has not improved at all in like 10 years. The results are way better now, tho. Thanks for the video, very clear instructions and tips!

Ahh, I was trying to do this photogrammetry using screenshots. Haha. Thank you for the video.

What about taking a video and then splitting it up into a series of still images? Seems like one could get thousands of pics that way?

Great video with a lot of tips. Thanks!

now this is a interesting topic... you could basically steal the blueprint of anything worth getting machined for example premium bike-frames or other stuff you can 3d-print or CNC it

This is a research tool, not a production tool. So the guy spends a whole day making just one part. Big deal.

Any options for AMD cards?

I hope something like this eventually comes to AMD GPUs. Haven't had an NVIDIA card since the 1050ti.

wow the scanning resoult is so good even without a 3d scanner crazy

I need LiDAR. I need to scan medium to large spaced and retain a high level of detail at mm or sub mm precision. And I need to be able to scan past 20 meters.

The issue I have is that everything on the market that can do this starts at $50,000 usd. And goes well north of that. The fact that they can get away with charging this much money in 2023 is a joke. I’m can’t believe that someone hasn’t made something in the $1000-4000 range. And for the love of got please don’t say iPhones or iPads. I’m talking about real scanners.

AMD 6900xt?

So, there is at least one person who knows how to use Meshlab. Impressive!

Photogrametry sux!

Blender can replace meshlab, and will give you undo support, just gotta use a different workflow.

The main idea of 3D scanning is that you don't need to do yourself 3D modelling. As long as it requires doing Topology manually after scanning it's not working as intended. You could 3D model this RC-Car by hand faster than you 3D scan it and then model manually

I got an error message for even thinking about doing this.

What is a much more powerful device. Calipers.

take a shot every time he says 'mesh'

Thank you, This helped me very much.

I've been looking for an open source 3D scanning tool to add to my FreeCAD and 3D printing tool chain. I need to make some parts that mate to someone else's fairly complex parts and I don't have their models. I'm a bit put off by the CUDA and nVidia requirements, but photogrammetry is definitely getting better.

You don't do your computer any favours including all that paving in the images

Wouldn't it be easier when you start aligning meshes, to use a mirror-build from the middle, for certain shapes?

Haha, they were never gonna give you the good tech. Like say, the scanning tech that the Chinese government uses to discern between all 1.5 billion people instantly. Because, spoiler alert, it exists in abundance everywhere. Instead we get the crude open source leftovers that don't employ any of the good tech that is secret or proprietary or under government contract. It should be immediately obvious to you that facial scanning technology, which is already widely deployed, has like 2 orders of magnitude better precision accuracy and speed than this consumer garbage. Yet you have to take 300 pictures and spend 2 hours meshing to get a dimensionally inaccurate blob. Because if they gave you the good tech you might use it to figure out that the guy in the Joe Biden mask isn't really Joe Biden🤣 Stop toiling in futility with this junky garbage. We all got played. It'll be at least 10 more years for all the patents to expire on the good tech. Then maybe this stuff will even be worth a shit to try.

Before I use something like meshlab I use blender which is way better for cleaning and also retopo

How do you take pictures of the bottom of the subject? There's a lot of detail underneath.

I've heard its possible to do proper scaling with CCTAGS. I'm having some issues with the workflow and I'd appreciate it if you had something for that. Archeo3d has worked with it before and made a printable for a turntable.

Good video thanks. I had tried Meshroom before but struggled with it. This is a really concise and clear path through it. Good work!

Absolutely excellent video. I run the same software on Linux. Thank you for the video.

Thanks for amazing tutorial! Question: I have a drone and want ro reconstruct a church, using this approach? Would it be possible?
