hi all
i am thinking to make 3d scanner using line laser pointer with rotation table and web camera all hardware is fine with
me Arduino and laser with camera mount is ok
i have reach to result like this
how i could convert this to .stl file with processing
i can convert the avi movie file to 360 photo like this
Uploading: 00000001.jpg…
Uploading: 00000006.jpg…
etc
etc
etc
etc
how to start this project any suggestions and help
thanks in advance
You need to incorporate depth values somehow.
from the 360 image how to collect them in one 3d image
deforming a sphere: Spherical Geometry - Coding Challenge #25 · The Coding Train
or deforming a cylinder would work I think!
Instead of a laser pointer, you can take a construction laser rangefinder and a rotating prism with a motor from an old laser printer, for vertical sweep. Leave the turntable.
there is laser pointer gives line laser called line laser pointer gives the same of your idea but standalone
No webcam needed. You need to use the native receiver rangefinder receiver. You will get depth.
i made the hardware and finished it
Clear. There was just such an idea.)))
thank you my dear i need to convert the images to 3d
Well, yes, a good laser rangefinder is expensive, it will not be possible to keep within 100 euro, and look for a prism. Camera, so camera.)))
I understand your idea.
I think it would be better to buy a real range measurement laser to get depth values as has been suggested.
Your idea is to make a movie while the rotation takes place.
Here you would need an image detection to see where the line is - maybe openCV will help?
Once you have a list of all frames and for each frames a list of all points x,y you are good to go. Just hammer them onto your cylinder shape.
here is some of my pre-results

is this 3D points from ONE frame? Or from many frames? Then when does one frame end and the next start?

apply this obj.file to your code it is open with any text editor can you ?
when ever you can i am not in harry i just have to be here with good people
this is the shape
Unfortunately I don’t have time
But I wish you luck.
