Most recent gaussian and nerf to mesh algorithms are surprisingly good at getting reasonable results for objects that traditional photogrammetry would struggle with. The main challenge are reflective and uniform surfaces (e.g. lether or co

the Lidar on the phone is only suited for medium/large objects (>50-100cm). but you are absolutely right about the lowest cost hardware option. The thought behind the scanner is having a self-contained unit which of course increase

The OpenScanCloud is just a convenience solution and most photogrammetry pipelines will outperform it. Meshroom is a fully open-source alternative (which needs quite some fiddeling...). And EpicGames just release RealityScan free for indivi

scanning furniture is quite a challenge for photogrammetry. your best option would be NERF or Gaussian splatting and manually guiding the camera.

Thank you and no worries, I absolutely agree with your valid criticism. Later this year I will get some more CT reference scans to compare my results too. I think that this will give some better insights. By the way, even on the professiona

Cyclododecan has been the industry standard for vanishing 3d scanning sprays, but as Cyclododecan is no longer available from the textile industry, this kind of spray does not exist anymore. Aesub Blue is a rather new product from a young G

Actually, this is how I started the project. See for instance this one here (OpenScan in 2019 https://www.instagram.com/p/Bt6JtjEoEM7/ ) But I have found that smartphones give very inconsistent results (probably du

Yes, this is the current public stage. The device is making a bunch of images, creating a zip file that need to be downloaded and manually processed. The main advantage already is, that the images and the lighting is very consistent, which

Hi, this is Thomas, the guy behind OpenScan. I really would like to clarify several things. - I have never made such a bold claim of 10 micron accuracy for the device. Yes, I made several scans, where the accuracy is quite good, but I woul
