Any Experience with Ciclops Scanners

  • Thanks for the links and I had seen a little bit about that in the past.

    Ok, perhaps not the best logic but the lack of many other people giving it a go on here or RepRap forums has encouraged me to give this a go.

  • Its a pain to get perfectly calibrated...

    I wouldnt recommend it...

    Look into photogrammetry instead 🙂

  • I got the impression the geometric accuracy of photogrammetry wasn't there?

  • It's mostly down to the technique and the amount of photos you can provide. For small objects you can get surprisingly good detail. It can't handle reflections at all, so getting a cheap polarizing filter, or dusting the object in corn starch can help a lot.

    I'd really like to put one of these together:
    As seen here:

    I've been experimenting with AutoDesk Recap. Even with the free trial it works quite well.

  • I could see some good examples of detail but less on geometric accuracy.

    What open source offerings are available to stitch the photos?

  • Ciclops? RUN the other way.

    Want one? You pay shipping... oh, not really... I binned it (saved the camera and stepper) because I'd NEVER inflict that thing on another human.

    Come on Danal, tells us how you really feel. 🙂

  • What were the issues you faced? I'm not expecting plug and play and plan to update the firmware and GUI.

  • My itteration on the Ciclop finally completed a scan last night. Running Horus on python 3 with freshly compiled versions of wxWidgits and OpenCV. To say it was a faff isn't doing it justice! The tweaked version of Horus is still very tempermental but happy to get a scan out of it.

    Now back to sorting a few P3Steels and getting RepRapFirmware to compile for RADDs on SamE70 XPLD...

  • @doctrucker what kind of quality?

  • Excuse the poor choice of sample part.

    The test bed set up. Some improvements needed but wanted to move away from the stock Ciclop parts as they were significant print times and lacked adjust-ability. Need to design in some more adjustment for the camera, but for the time being moving the extrusion about has sufficed.

    Here the first complete scan. This looks a little better than it really is as it is colour textured which gives more of an impression of 3D texture than there actually is. I will scan again without the image capture, and have yet to work through the rest of the software tool chain to go from point cloud to STL file.

    Edit: This is far from an off the shelf thing. It has been a real effort to get it working and it needed me to delve around in the code in order to get it working. Made more difficult by me deciding to use the latest libraries for wx, OpenCV and moving the whole lot to Python3. Latter was part done by someone else, but even that didn't run without a fight. Only tested in Ubuntu.
