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.
I know two ways around that issue. Option A: Mount your object on a pole at a height that allows you to take pictures from above and below. Option B: Perform two scans, one with the object flipped upside down, and merge them digitally. Meshlab has the Alignment tool for that purpose.
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.
I'd say it depends. While it does increase processing time, in my experience it also increases the likelihood of all camera positions being reconstructed successfully.
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.
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 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.
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
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!
@@horrorhotel1999 I think he means the laborious steps involved are the same as ever (no advances in automation), but the 3D reconstruction you get at the end is better. I don’t know whether that’s true, but it’s not contradictory.
Not much. You'll still want to get pictures evenly around the object. Professionals use a drone for that. If that's not an option, take pictures close and further away from the house. Then, depending on your roof you might not get good reconstruction there. For scaling you could use the length of a wall for example.
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.
Like handwritten or printed? I feel like tesseract should be able to do it if it's printed. If memory serves there is a language pack for math symbols.
@@oliverer3 Yes, I have tried Tesseract as well as numerous open-source tools and private software like PDF elements. I have some old scanned books that are no longer available in my country, but they are low-quality images in the form of old PDFs. Unfortunately, I haven't come across a single AI tool that can accurately recognize the text and transcribe it directly into a format like Markdown or LaTeX, especially when it comes to mathematical formulas and other symbols.
@@Maisonier You could probably use a combination of tesseract and OpenCV to do it then but it would take a decent amount of manual effort to tune it. Plug and play tools are probably not there yet.
hahah That’s pretty wild. I did that on one of my other channels. Just had some mobile game footage from years ago and posted a flight training video. (with a real airplane, not a video game) Just wanted to backup the files somewhere else besides the phone because it was overheating and the battery was expanding in thickness. Didn’t want to have to wait until I could order a new battery to get to the video files, in case the battery completely failed or even burst open. Ended up uploading public by accident and didn’t realize it till I got home hours later. Some of my old game buddys saw it along with a “face reveal” lol
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.
