system requirement for designing 3d scan device #2400

Open amira133 opened 2 months ago

amira133 commented 2 months ago

Hello I want to design a 3D scanning device that has an accuracy of 0.1 mm and a resolution of 0.2 mm. What camera, sensors and instructions do you recommend for this? If you know any help in this field, please send it. Thanks

Depends on your use case. For macro, take a look at https://www.youtube.com/watch?v=hnB7sApWzss

Thanks for your reply @natowi I want to use it for 3D scanning of industrial piece. I am looking for the design of a 3D handy scanning device(like Shining 3D pro 2), do you know any guidance on this matter, what are the challenges and what camera model is suitable for this? As I understand, there are many cameras for this work, but I did not find an answer as to which one can produce 0.1 mm accuracy in practice. Do you have experience in this field? Is there a forum to exchange information in this field?Can use Meshroom for this accuracy?

You know that you need a laser scanner for the precision you are aiming for?

I know that a German car builder uses Shining "3D FreeScan Trio 3D Scanner" for precision. The measurement comes from the scanner and the texture from the cameras
