3D scanner for tire profiles

Hey guys,

I have some basic knowledge in 3D printing with the ultimaker.
Now I want to try my luck with 3D scanning of tire profile for my university job.

I can't post a schematic experiment setup, but the width of the wheel is like 20cm.

The range from the sensor to the profile is adjustable between 20cm and 70cm, so that I could get the maximum resolution out of my sensor.
I want a really precide depth image (if possible in the mm range) so that I can create a 3D model out of it and print it.

Most 3D scanners work with a rotating table and I am unsure, if it is still possible to create a flat 3D Image without expensive software.

As a sensor, I am also unsure. I've read a lot of good things about the Intel RealSense 415/435 and the StereoLab ZED. But from what I've read in a lot of reviews/tests both don't seem to have a mm resolution for the depth images. And TOF sensors also don't seem to work for this accuracy.

Do you have experience with the recording of surfaces with high depth resolution? I would like to edit the measurement data later with a software.


Thanks,

if it was me and I had someone elses money to spend I'd get a https://www.scaninabox.com/
scan in a box machine. Structured light scanner.
(didn't realise faro had bought them out).

That said what you really want would probably cost ?20,000 ish: https://www.faro.com/en-gb/products/...freestyle3d-x/

These things are great, but also a little bit too expensive.
Something around 500-1000 would be great. :)

yes it would be - but it doesn't actually exist :-)

Intel real sense promised great things. But they have yet to appear.

Intel RealSense is basically a Kinect V3, no?
