3D scanner project feedback needed

by DylansPrints1234

Update on project !!!
I have chosen to make a 3D Scanner as this would most suit my project work. ( this will be most likely 3D printed an available on this platform once finished !!!!)
My new question to you is: What features would you like on a 3D Scanner ?
some examples are :
•Automatic moving turntable
-mechanical moving turntable
•stationary turntable with camera which rotates around automatically at every angle e.g. in a spiral
•laser deformation sensing
•Multiple cameras
•portable
•large scale scanning
•small object scanning
etc

Thank you !!!
(I promise it will be unique)

Absolutely free photogrammetry path of mine

by yazkili

Some of the photogrammetry services or programs became out of free by time. I wanted to share my realy free method for current time:
After taking a series of photos or extracting extracting them from a video with VLC, i edit them by GIMP with or similiar free picture editing applications.
I use MVE at linux envirement. a little script is making the process easier to work. I guess there is way to use it with windows but i didn't try. MVE gives you a mostly cleaned dens point cloud at the end.
Then i preffer MESHLAB for more cleaning, repairing and simplification. Either MESHLAB can be used both at linux or windows.
At the last step, TINKERCAD is my favorite service to modify the STL file before printing. https://stephaneginier.com/sculptgl/ is an other usefull web site for more editing.

3DF Zephyr, Blender and Meshmixer - 1st photogrammetry attempt

by aprilla

Samsung Galaxy S4 phone camera, I took 12 pictures at 3 levels for a total of 36 (and one from the top made 37 but it was rejected) outside with good light.
Imported photos into 3DF Zephyr (free) and it did it's thing (I need to find out all about what it's doing). I then exported a ply file which I couldn't open in Meshmixer so went back and created a obj file. This looked dreadful in Meshmixer, full of big holes and little gaps and quite unlike the 'nice' image I'd seen in 3DF Zephyr. So I tried to open this in Blender (which I also don't know) and it looked fine, so exported it to a stl and Meshmixer loaded this fine.
Played with the stl in Meshmixer enough to think I'm going to enjoy this new learning curve... and there's a lot to learn.

I'm pretty pleased with this though :)

First attempt photogrammetry (3DF Zephyr, Meshmixer, Blender)

by aprilla

Samsung Galaxy S4 Camera. I took 37 outside photos, 12 around at three heights and 1 top view. It used 36, rejecting the one of the top of the head.
I'm still pretty confused by the settings available in 3DF Zephyr when it comes to saving the final file so there's much learning to do.
Meshmixer is easy but hard. Once you fathom just how a thing you want to do should be done it's fine, figuring out that approach is quite the adventure :)

3DF Zephyr Free seems just a matter of clicking through stages and doing a clean up of floating bits in the sparse and dense clouds. When I brought the 3DF Zephyr obj file into Meshmixer it was very different to what I'd seen in 3DF Zephyr. It was a bit of a shock, there were missing bits, big holes and it looked real bad. I'll need to find out why this is, or learn Blender because when I opened that same obj file in Blender it was intact, looked just as the 3DF Zephyr file did. I couldn't fathom Blender at all to actually do anything but was able to export as a stl file. Meshmixer accepted this stl file and I was good to mess it up. I did try a ply file first but can't remember why I went to obj, maybe Meshmixer wouldn't open the ply and I hadn't yet considered Blender.

3DF Zephyr Free is the only photogrammetry software I've used so far. I might try out a few others but considering this is a first go I'm really pleased. It's pretty mind boggling really.
I need to make an amusing focal point to keep other victims smiling through the photo shoot LOL

Advice always welcome

:)
